A new study examined the maintenance of memory B cell responses to SARS-CoV-2, the virus that causes COVID-19, after recovery from natural infection or post-vaccination. The study is published in the peer-reviewed journal Viral Immunology. Click here to read the article now.

The study, coauthored by David Fear, from Kings College London, and colleagues, showed that among those recovered from natural infection, COVID-19 serologically-positive donors had strong antigen-specific memory B cell-associated responses. Post-vaccination, donors showed robust serological antigen-specific antibody responses against spike protein that waned over time. Memory B cell-associated responses against spike protein were also observed but showed less waning over time.

This study is of particular relevance at the moment, because with millions vaccinated, previously infected, or both, studies such as this one may tell us how long we might expect the immunity to last, says Rodney S. Russell, PhD, Editor-in-Chief of Viral Immunology, from Memorial University of Newfoundland, St. Johns.

Accelerating Transformational Research into Cell Transplantation for Patients with Type 1 Diabetes – UCSF

Loren and Mike Gordon. Image by Sonya Yruel

A personal investigation into the lifelong implications of his type 1 diabetes (T1D) culminated in a $7 million gift from Mike Gordon, co-founder of Meritech Capital Partners, and his wife, Loren, to help UCSF surmount a key impediment to treating the disease. The funds will support world-class stem cell biologists, immunologists, and bioengineers who are working to overcome significant barriers to beta-cell replacement therapy as an effective treatment for T1D.

Diagnosed when he was just 22 months old, Gordon went through a whole pancreas transplant at UCSF nearly 12 years ago. As a result, he has fewer complications from T1D but must take immunosuppressant drugs and endure the health risks that come with them for the rest of his life.

We wanted to give these researchers freedom to explore bold ideas.

Mike Gordon

Ive suffered a lot from this disease, Gordon said. People say, Its not that bad. Its a chronic condition. But you can fall apart.

Some 1.6 million people in the US have T1D, a disease that is often disabling and can become life-threatening. Diagnoses typically occur in childhood, but not always. The disease develops when the patients immune system attacks its own beta cells, which make insulin in the pancreas. The resulting lack of insulin leaves the body unable to absorb sugar from the bloodstream and convert it into energy, so sugar builds up in the blood. Patients are subject to a lifelong dependence on insulin and are at a higher risk for heart disease, blindness, kidney failure, and other chronic conditions, in addition to shortened average life expectancy.

Beta cell-replacement therapy has shown enormous promise for T1D patients. Beta cells make up 50%-70% of the cells in human pancreatic islets groups of cells in the pancreas that produce blood glucose-regulating hormones and they are the sole producers of insulin in the body. However, replacement beta cells dont live long, and the immune system often rejects the ones that do survive. To prevent the immune system from attacking the replacement cells, immunosuppressants are necessary, but they can be toxic and leave patients vulnerable to malignancies and other infections. UCSF scientists are poised to find solutions to these challenges.

So often the NIH provides funds for low-risk projects where outcomes are more predictable, Gordon said. We didnt want that; we wanted to give these researchers freedom to explore bold ideas.

The research team will use the Gordons investment to help answer two big questions: How can they prolong the survival of replacement beta cells after transplantation? And, can the need for patients to take immunosuppressive drugs be eliminated? The answers to these questions will be a game-changer for patients around the world.

Four interdisciplinary investigators will lead the research:

Julie B. Sneddon, PhDAssistant professor in the UCSF Diabetes Center, the UCSF Broad Center of Regeneration Medicine and Stem Cell Research, and the UCSF Department of Cell and Tissue Biology

Currently, islet-cell replacement relies on obtaining pancreatic tissue from deceased human donors. Thanks to groundbreaking advances during the last decade, beta cells can now be laboratory-generated from pluripotent stem cells, which means supplies, in theory, are unlimited. This creates an opportunity to engineer the stem cell-derived beta cells in ways that support their survival and help them avoid attack by the immune system.

We used to say we were 10 years away from a cure for T1D. We still might be. But if you look at the advances in cell biology and immunology, we have the road map now, Parent said.

Over the past five years, Drs. Parent, Tang, Sneddon, and Desai have co-advised trainees, joined forces on numerous projects, and published papers together. Their labs combine the fresh perspectives and innovation of junior faculty members with the expertise and experience of senior faculty members. The groups collective knowledge, unique understanding, and productive ongoing collaborations position them as an effective group to take on this challenge.

Insulin was first used to successfully treat a patient with type 1 diabetes a century ago, but it wasnt until 1980 that two Minnesota surgeons demonstrated successful intraportal islet transplantation in 10 patients with surgically induced diabetes (in which the patients own islet cells, or autografts, were infused back into their bodies after islet isolation). Ultimately, three of those patients achieved insulin independence for one, nine, and 38 months, respectively. In the last decade, significant strides have been made in groundbreaking technologies such as immunotherapy, metabolomics, and genomics. UCSF has been at the forefront of these advances, especially in immunology, with the Bakar ImmunoX initiative driving collaborative science and the UCSF Helen Diller Family Comprehensive Cancer Center using immunotherapies to find cures for some cancer patients.

All this progress has positively impacted diabetes research. Mark Anderson, MD, PhD, the Robert B. Friend and Michelle M. Friend Professor of Diabetes Research and the new director of the UCSF Diabetes Center, is optimistic about this moment in time and what it means for our patients with T1D and other diseases.

These developments provide unique opportunities for physician-scientists to research the molecular causes of diseases like T1D and potentially replace damaged tissues and repair malfunctioning organs, Anderson said.

Anderson believes that UCSF is one of the few places in the world capable of assembling this type of collaborative team. We are so fortunate to have the Gordons support and shared vision to help us realize the potential of cell transplantation without immune suppression, which could completely change the lives of those affected by T1D.

Grant Funds Study of the Role of Fungi in Cancer Development and Immunotherapy – Weill Cornell Medicine Newsroom

Dr. Iliyan D. Iliev, an associate professor of immunology and microbiology in the Division of Gastroenterology and Hepatology and a member of the Jill Roberts Institute for Research in Inflammatory Bowel Disease at Weill Cornell Medicine, has been awarded a five-year, $1.25 million CRI Lloyd J. Old STAR (Scientists Taking Risks) Program grant from Cancer Research Institute (CRI).

Dr. Iliyan D. Iliev

The non-profit CRI focuses on pursuing innovative research that could improve the way cancer patients are diagnosed and treated. The STAR program is a competitive grant that supports gifted, mid-career scientists who are working at the intersection of immunology, technology and bioinformatics. The aim of the program is to fund high-risk/high-reward research that has the potential to transform cancer patient responses to immunotherapy.

The grant will allow Dr. Ilievs lab to continue research that investigates relationships between certain types of fungi and specific cancers. His winning grant proposal stems from his study of patients with ulcerative colitis who later developed colorectal cancer. Dr. Iliev and his lab colleagues noticed that some cancer patients share unique microbiome composition where specific fungal strains prevailed.

We found that some patients carry specific fungal strains that expand and produce a toxin that affected inflammation, said Dr. Iliev, who is also co-director of the Microbiome Core Lab at Weill Cornell Medicine. One of the questions is whether the presence of these and other fungi influence cancer development and outcomes.

By isolating certain fungi and observing what they do in mouse models, Dr. Iliev and his colleagues will be learning about fungal biology within the tumor microenvironment. Those discoveries lead them back to cancer patients where these fungi originate.

This back-and-forth process, moving between mouse models and patients, is a catalyst for developing innovative ways to investigate and hopefully treat various forms of cancer. Its a new hypothesisa there are new players, Dr. Iliev said. There have been reports of certain fungal species associated with pancreatic cancer, for example. Now we have developed methodologies allowing us to assess microbial components in multiple tumor types to tune hypothesis and modeling promptly.

Dr. Iliev is excited about the opportunity to cross-fertilize the cancer field with discoveries about fungal and bacterial organisms linked to the inflammatory bowel diseases he studies. This funding is fantastic because it allows us to go in with an early hypothesis, he said, and gives us the freedom to go after what is really interesting in search of new and exciting ideas.

New method of inciting immunological responses is revealed – ThePrint

Washington [US], July 17 (ANI): Small proteins, called chemokines, that direct immune cells toward sites of infection can also form DNA-bound nanoparticles that can induce chronic, dysfunctional immune responses, according to a new study.

The surprising discovery of this new activity for this well-studied class of immune signalling molecules could shed light on some types of immune disorders.

The study, published May 31 in the Journal of Experimental Medicine, reveals an entirely new mode of triggering the immune system, through which chemokine-DNA nanoparticles can induce inflammation. Results in preclinical models suggest that this mechanism may play a central role in autoimmune diseases such as scleroderma and lupus.

The work was part of the scientists ongoing efforts to understand scleroderma, an autoimmune condition that causes inflammation and hardening of the skin. We had a project looking at scleroderma and it was shown by us and others a few years ago that patients with this condition have an elevated level of the chemokine CXCL4 in their blood, said senior author Dr. Franck Barrat, professor of microbiology and immunology at Weill Cornell Medicine and the Michael Bloomberg Chair and senior scientist at HSS. But the role of this chemokine in disease is unclear and we didnt expect the chemokine to provoke this particular immune response.

In setting up controls for one of their experiments, Dr. Barrats team, including first author, Dr. Yong Du, a postdoctoral associate in microbiology and immunology at Weill Cornell Medicine and a member of the HSS Research Institute, discovered that CXCL4 and several other chemokines could induce immune cells called plasmacytoid dendritic cells (pDCs) to produce interferon-alpha. Surprisingly, the induction appeared to be independent of known chemokine receptors, indicating that these molecules were activating the immune cells through some previously unknown mechanism.

Subsequent experiments revealed that the chemokines can bind pieces of DNA to form nanoparticles, which then bypass the cells chemokine receptors to induce interferon production directly. Tests in mouse models of skin inflammation suggest that this mechanism could account for the chronic immune activation that underlies scleroderma and other autoimmune diseases. The results also suggest that different DNA-chemokine nanoparticles could underlie different diseases. For example, while CXCL4 appears to be important in scleroderma, another chemokine, CXCL10, may perform a similar function in lupus.

Dr. Barrat believes that the DNA-chemokine nanoparticles are likely an essential component of the bodys wound healing system. Following a skin injury, such as if you cut yourself, dendritic cells infiltrate the skin and create an inflammatory environment to allow for proper closing of the wound. Our findings suggest that these cells do not need to see a pathogen a virus or bacterium and can directly sense self-DNA, he said. And that inflammation is helping to recruit other cells of the immune system. In autoimmune disease, the process goes awry, producing a chronic inflammatory state that ultimately damages tissue instead of healing it.

The researchers also collaborated on a related study, published June 14 in Nature Communications, that shows that CXCL4 can induce a similar inflammatory response in monocytes, another important class of immune cells. Taken together, the findings point toward possible strategies to shut down autoimmunity without interfering with normal immune responses.

It tells you the type of response that you have to stop, not necessarily at the DNA-chemokine level, but potentially more downstream in the cells themselves, Dr. Barrat said. (ANI)

GenFleet Receives CTAs Approval for Two Phase II Combination Studies of TGF- R1 Inhibitor (GFH018) with PD-1 Inhibitor – BioSpace

SHANGHAI, July 22, 2022 /PRNewswire/ --GenFleet Therapeutics, a clinical-stage biotechnology company focusing on cutting-edge therapies in oncology and immunology, announced China's National Medical Products Administration (NMPA) has approved the Clinical Trial Applications (CTAs) for GFH018 in two clinical studies for combination therapies.

One study is a phase Ib/II trial of GFH018 with PD-1 inhibitor treating patients with advanced solid tumors; the other study is a phase II trial of GFH018, PD-1 inhibitor with concurrent chemoradiotherapy treating patients with locally advanced & unresectable NSCLC. GenFleet has completed a phase I trial of GFH018 monotherapy treating solid tumors in early 2022, and the data will soon be published in relevant international medical conference.

"Pre-clinical in-vivo data have demonstrated desirable anti-tumor effects of GFH018 in combination with PD-1 inhibitors; the combo studyGFH018X0201being conducted in Australia and China's Taiwan has completed the dose escalation phase (phase Ib), with the dose expansion phase (phase II) currently ongoing. From this multi-regional, multi-center clinical trial, we expect to collect additional evidence to further confirm the efficacy of combination therapies with GFH018 in cancer patients. In the study of GFH018, PD-1 inhibitor with concurrent chemoradiotherapyGFH018X1202, we will investigate the combination's potential in improving the immunosuppressive microenvironment and reducing the side effects from concurrent chemoradiotherapy." said Yu Wang, M.D./Ph.D., Chief Medical Officer of GenFleet.

"GFH018 is GenFleet's first product that has moved into clinical development stage. The progress of GFH018's multi-regional studies clearly demonstrates GenFleet's capability in global regulatory registration, patient enrollment and market positioning, and will substantially accelerate GFH018's global clinical development. TGF- signaling pathway has been studied as a critical target in multiple solid tumors; however, no drugs have been approved to date for this pathway. GFH018 is a small molecule drug designed to specifically target and inhibit TGF- R1, and the discovery and development of GFH018 truly reflects GenFleet's strategy of novel mechanism-focused innovation in drug development. GenFleet expects the development of the GFH018 to bring a novel therapy with great clinical benefit to cancer patients. "said Jiong Lan, Ph.D., Chief Executive Officer of GenFleet.

Both studies are multi-center, single-arm, and open-label trials designed to evaluate the safety/tolerability and efficacy of the GFH018 in combination therapies. Shanghai Oriental Hospital and Sun Yat-Sen University Cancer Center will lead the phase Ib/II study evaluating the combination of GFH018 and anti-PD-1 monoclonal antibody conducted in over 20 domestic hospitals. The safety/tolerability and efficacy of combination of GFH018, anti-PD-1 monoclonal antibody, concurrent chemoradiotherapy will be evaluated in the phase II study, which will be conducted at over 10 hospitals including West China Hospital of Sichuan University, Peking Union Medical College Hospital.

About GFH018 and TGF- R1

Developed by GenFleet Therapeutics, GFH018 is an orally administered TGF- R1 inhibitor and entered into phase I clinical trial in 2019. Preclinical data showed evidence of GFH018's good anti-tumor properties against cancer cells in vivo and in vitro. Besides, translational and mechanistic studies confirmed it effectively acts on TGF- signaling pathway and synergizes with checkpoint inhibitors.

In the microenvironment of advanced solid tumors, TGF- signaling pathway can promote epithelial mesenchymal transition (EMT) & metastasis, induce the formation of cancer stem cells and their functional maintenance, inhibit anti-tumor immunity, enhance vasculature and fibrosis, and ultimately result in tumor progression. Among patients of hepatocellular carcinoma, glioma, colorectal cancer, lung cancer, pancreatic cancer, urothelial cancer and other solid tumors, high expression of genes related to TGF- signaling pathway is frequently discovered in their blood and tumor tissues. The expression level is positively correlated to the malignancy & poor differentiation of tumor and unfavorable prognosis in patients.

About GenFleet Therapeutics

GenFleet Therapeutics, a clinical-stage biotechnology company focusing on cutting-edge therapies, is dedicated to serving significant global unmet medical needs in oncology and immunology. Based on the deep understanding of disease biology and translational medicine, GenFleet's proprietary and fully integrated R&D platform highlights multiple cutting-edge products with novel mechanisms and global IP.

13-Year-Old Accepted to Medical School | MedPage Today – Medpage Today

At 13 years old, Alena Analeigh Wicker is on her way to medical school.

Wicker, who lives just outside of Forth Worth, Texas, learned in May that she had been accepted into the University of Alabama at Birmingham Heersink School of Medicine for 2024 through the Burroughs Wellcome Scholars Early Assurance Program, the Washington Post reported this week.

The child prodigy is more than 10 years younger than the average incoming medical student, the Post noted. And she is the youngest Black person to ever get accepted into a medical school in the U.S., KPNX-TV reported.

"I'm still a normal 13-year-old," Wicker, who recently began using her middle name, Analeigh, as her surname, told the Post. "I just have extremely good time management skills and I'm very disciplined."

She is currently a student at both Arizona State University and Oakwood University in Huntsville, Alabama, and is simultaneously earning two separate undergraduate degrees in biological sciences, the Post reported. She takes most of her classes online, but also spends time on campus completing labs.

Just last year, Wicker spoke with KPNX-TV about her acceptance to Arizona State University's engineering program at age 12. While she originally had hopes of working for NASA, her passion for biology shifted her focus to medicine.

"It actually took one class in engineering for me to say this is kind of not where I wanted to go," she told the news outlet. "I think viral immunology really came from my passion for volunteering and going out there engaging with the world."

"What I want from healthcare is to really show these underrepresented communities that we can help, that we can find cures for these viruses," she added.

Wicker's current timeline means that she'll become a doctor at 18, and she hopes to encourage her peers to follow in her footsteps.

About a year and a half ago, she started an organization called the Brown STEM Girl, aimed at providing opportunities to girls of color who are interested in exploring careers in science, technology, engineering, and math.

Wicker told the Post that she wanted to create the organization for girls like her "to feel like they belong somewhere."

She was also named one of Time's Top Kid of the Year Finalists for 2022.

In her spare time, Wicker plays soccer and participates in track and field, according to the Post. Some of her hobbies include going to the arcade with friends, singing, cooking, and traveling.

In a recent post on Instagram, she wrote that she was "grateful," noting that she had graduated high school just a year ago, the Birmingham Times reported.

"Statistics would have said I never would have made it," she added. "A little black girl adopted from Fontana, California. I've worked so hard to reach my goals and live my dreams. Mama, I made it. I couldn't have done it without you."

Wicker told the Post that she wants to continue to advocate for other young people.

"It feels amazing to be able to create a path for girls that look like me," she said. "It doesn't matter how old you are. You can do it. Don't let anybody tell you no."

Jennifer Henderson joined MedPage Today as an enterprise and investigative writer in Jan. 2021. She has covered the healthcare industry in NYC, life sciences and the business of law, among other areas.

Structure of Antibodies Could Be Key to More Effective Cancer Treatments – Lab Manager Magazine

Researchers at the University of Southampton have gained unprecedented new insight into the key properties of an antibody needed to fight off cancer.

The interdisciplinary study, published in Science Immunology, revealed how changing the flexibility of the antibody could stimulate a stronger immune response.

The findings have enabled the Southampton team to design antibodies to activate important receptors on immune cells to fire them up and deliver more powerful anti-cancer effects.

The scientists believe their findings could pave the way to improve antibody drugs that target cancer as well as other autoimmune diseases.

In the study, the team investigated antibody drugs targeting the receptor CD40 for cancer treatment. Clinical development has been hampered by a lack of understanding of how to stimulate the receptors to the right level. The problem being that if antibodies are too active they can become toxic.

Previous Southampton research has shown that a specific type of antibody called IgG2 is uniquely suited as a template for pharmaceutical intervention, since it is more active than other antibody types. However, the reason why it is more active had not been determined.

What was known, however, is that the structure between the antibody arms, the so called hinges, changes over time.

This latest research harnesses this property of the hinge and explains how it works: the researchers call this process disulfide-switching.

In their study, the Southampton team analyzed the effect of modifying the hinge and used a combination of biological activity assays, structural biology, and computational chemistry to study how disulfide switching alters antibody structure and activity.

Dr. Ivo Tews, associate professor in structural biology at the University of Southampton, said: Our approach was to analyze the structure of the antibody in atomic detail, using the method of X-ray crystallography. While the resulting picture is very accurate, the information on how they move their arms is missing, and we needed an image of the antibody in solution, for which we used an X-ray scattering approach called SAXS. We then used mathematical models and a chemical-computing approach to analyze the data, using the Southampton High Performance Computing cluster IRIDIS.

Through this detailed study of the hinge the team revealed that more compact, rigid antibodies are more active than their flexible counterparts.

Professor Mark Cragg, of the Centre for Cancer Immunology at the University of Southampton, said: This study has given us new information about how to engineer antibodies to deliver a better immune response. We propose that more rigid antibodies enable the receptors to be bound closer together on the cell surface, promoting receptor clustering and stronger signaling for activity. This means by modifying the hinge we can now generate more or less active antibodies in a more predictable way.

Excitingly, our findings could have wider implications as it may provide a highly controlled and tractable means of developing antibodies for clinical use in future immunostimulatory antibody drugs.

The study was funded by Cancer Research UK and brought together structural biologists, immunologists, chemists and computer experts from across the University. Collaboration with the Diamond Light Source in Oxford and the University of Hamburg that Southampton is partnered with were instrumental to these studies.

Cuban vaccine against lung cancer makes its way into the UAS – The Point – The Point

The Cuban Molecular Immunology Center (CIM) and the Roswell Park Cancer Research Center, in Buffalo, USA, joined forces a few years ago to facilitate access to equipment and reagents, in order to promote the development of the drug, a relationship that has not been without difficulties, due to the economic blockade policy against Cuba.

The creation of the only joint venture between Cuba and the United States, the biotechnological company Innovative Immunotherapy Alliance, with the purpose of introducing the drug into American society, provided Cuba with access to equipment and reagents that are very difficult to obtain due to the limitations of the coercive measure, while the US can access a drug with excellent results and prospects.

Dr. Elia Neninger, who has participated in clinical trials of the therapeutic vaccine since the beginning, assured that the drug has two great advantages: few adverse reactions and a solution to a serious health problem on the island, such as lung cancer.

Kalet Len Monzn, deputy director of the Center for Molecular Immunology, said that the beneficiary patients recover from an advanced tumor cancer that could have a very short-term prospect of survival under normal conditions.

One of those favored with the vaccine, Miguel Creus, a patient who began receiving Cimavax 15 years ago, when the disease was in phase four and the vaccine was in clinical trials, assures that the drug has prolonged his life with a state of satisfactory health. He currently has no traces of tumors or symptoms of the disease.

Despite the effects of the economic blockade of the White House, the collaboration between both institutions does not stop, and Cimavax overcomes the challenges. There are currently clinical trials that combine this Cuban vaccine with other successful cancer treatments, and their effects are being studied in high-risk people or patients in the initial stage of the disease.

According to some studies, lung cancer is the third most common cancer in the US, but the deadliest. A promising relief could be this Cuban drug, a good example of the benefits that both nations would obtain if they had a normal relationship.
