Straight Men With ‘Bisexual Genes’ Have More Kids, Study Finds – ScienceAlert

For the first time, scientists have identified genetic variations associated with human bisexual behavior and found these markers are linked to risk-taking and having more offspring when they are carried by heterosexual men.

Jianzhi "George" Zhang, a professor at the University of Michigan and senior author of the new research, told AFP it helped answer the long-standing evolutionary puzzle of why natural selection has not eliminated the genetics underpinning attraction within the same sex.

The study, published Wednesday in Science Advances, was based on data from more than 450,000 people of European descent who signed up for the UK Biobank, a long-term genomics project that has proven a major boon for health research.

It builds on growing research including a seminal 2019 paper in Science that found genetic variants influenced to some extent whether a person engaged in same-sex behavior, though environmental factors were more important.

"We realized that in the past, people lumped together all homosexual behavior but actually there's a spectrum," Zhang said, explaining part of the motivation for the new work.

By studying participants' complete sets of DNA, or genomes, and combining that information with survey responses, Zhang and his co-author Siliang Song were able to confirm the signatures associated with same-sex behavior and bisexual behavior were in fact distinct.

This meant they could be analyzed separately which in turn revealed that male heterosexuals carrying the markers, which they called bisexual behavior (BSB)-associated alleles, father more children than average and thus carry those genes forward.

What's more, men who describe themselves as risk-takers tended to have more children and were more likely to carry BSB-associated alleles.

"Our results suggest that male BSBassociated alleles are likely reproductively advantageous, which may explain their past persistence and predict their future maintenance," the authors wrote.

Although the UK Biobank's survey simply asked respondents whether they considered themselves risk-takers or not, it is likely risk-taking behavior involves more unprotected sex and more partners.

"Nature is complicated," said Zhang, reflecting on the fact that a single gene can influence multiple traits a phenomenon known as "pleiotropy."

"Here we're talking about three traits: number of children, risk taking, and bisexual behavior: they all share some genetic underpinnings."

On the other hand, exclusive same-sex behavior (eSSB) associated alleles were correlated with having fewer children when carried by heterosexual men suggesting that over time these traits will fade away.

However, the UK Biobank data also revealed the proportion of people reporting both bisexual and homosexual behavior has been rising for decades, which is probably due to growing societal openness.

The authors estimated, for instance, that whether a person is bisexual or not in their behavior is 40 percent influenced by genetics, and 60 percent by the environment.

"We want to make it clear that our results predominantly contribute to the diversity, richness, and better understanding of human sexuality," they stressed.

"They are not, in any way, intended to suggest or endorse discrimination on the basis of sexual behavior."

Genetic Influence on COVID-19 Vaccine Response Revealed – Medriva

Unveiling the Genetic Influence on COVID-19 Vaccine Response

A recent genome-wide association study published in The American Journal of Human Genetics has shed light on the genetic factors that play a pivotal role in how individuals respond to COVID-19 vaccination. By using the comprehensive data available from the U.K. Biobank, researchers have identified significant genes, particularly the alleles from the HLA class II, that are linked to the IgG serostatus against the SARS-CoV-2 spike protein. This groundbreaking revelation is expected to shape future vaccination strategies, taking into account these genetic variations.

Among the identified alleles, the HLA-DRB1*13:02 allele displayed the most significant effect in protecting against seronegativity of IgG antibodies. In simpler terms, individuals possessing this particular allele have a higher likelihood of developing a positive IgG antibody response following COVID-19 vaccination. The alleles protective effect against IgG seronegativity has significant implications for understanding individual immune responses to the vaccine and devising effective vaccination strategies.

Another intriguing finding from the study was the shared genetic predisposition between the IgG serotype status and increased susceptibility to or severity of COVID-19. This implies that the same genetic factors that determine an individuals antibody response to the vaccine might also influence their susceptibility to the virus and the severity of the disease if infected.

The impact of HLA alleles on IgG responses was found to be cell type-specific. This implies that the influence of these genetic factors differs based on the cell type, adding another layer of complexity to the understanding of immune responses to COVID-19 vaccines. This finding necessitates further research to unravel the intricate relationship between these genetic factors and the cell types they affect.

The studys findings underscore the pressing need to consider the influence of constitutive genetics when designing vaccination strategies for diverse populations. As the HLA class II alleles significantly impact the bodys immune response to the vaccine, individualized vaccination strategies might be necessary to ensure optimal vaccine effectiveness for different individuals.

In a separate study, researchers investigated the time-dependent changes in SARS-CoV-2 antibody responses in infected and/or vaccinated and unvaccinated individuals. It was found that antibody levels declined after infection but persisted for at least 68 months. Individuals who had received only CoronaVac had higher anti-nucleocapsid antibody levels in the early months than those who received mixed vaccination. However, anti-spike antibodies persisted longer and at higher levels in individuals who had received mixed vaccinations. This finding suggests that combining two different vaccine platforms may provide a synergistic effect, informing future vaccination strategies.

In conclusion, understanding the genetic determinants of the IgG antibody response to COVID-19 vaccination is crucial to enhancing vaccine effectiveness and developing personalized vaccination strategies. The role of the HLA-DRB1*13:02 allele and the impact of HLA alleles on various cell types provide pivotal insights into the biological mechanisms contributing to variations in immune responses elicited by COVID-19 vaccines. Furthermore, the dynamics of antibody responses to COVID-19 infection and vaccination further underline the importance of considering individual differences in designing effective vaccination strategies.

IKAROS: Unlocking the secrets of the immune system’s key player – News-Medical.Net

In a scientific breakthrough that aids our understanding of the internal wiring of immune cells, researchers at Monash University in Australia have cracked the code behind IKAROS, an essential protein for immune cell development and protection against pathogens and cancer.

This disruptive research, led by the eminent Professor Nicholas Huntington of Monash University's Biomedicine Discovery Institute, is poised to reshape our comprehension of gene control networks and its impact on everything from eye colour to cancer susceptibility and design of novel therapies.

The study, published in Nature Immunology, promises pivotal insights into the mechanisms safeguarding us against infections and cancers. When the transcription factor Ikaros/Ikzf1 was deliberately obstructed, be it in preclinical models or humans, the once-mighty activity of Natural Killer (NK) cells, our immune system's frontline warriors, plummeted. Loss of this transcription factor in NK cells resulted in wide-spread dysregulation of NK cell development and function, preventing their ability to recognize and kill virus-infected cells and clear metastatic tumour cells from circulation. Aiolos/Ikzf3 and Helios/Ikzf2, related family member were found to partial compensate for the loss of Ikaros, as such when multiple IKZF-family members were inhibited, NK cells underwent rapidly death. Mechanistically, Aiolos and Ikaros were found to directly bind and activate most members of the JUN/FOS family, transcription factors known for their essential roles in human embryo development and tissue function.

This discovery opens the door to the prospect of potential novel cancer therapeutics. NK cells, our first line of defence against pathogens and internal threats like cancers, could be fortified by therapies enhancing their killing prowess by targeting IKAROS and JUN/FOS biology.

Professor Huntington notes that drugs targeting IKAROS/AIOLOS have already received approval from the US Food and Drug Administration (FDA) and local Therapeutic Goods Administration (TGA) for the treatment of B cell malignancy "but until now we haven't understood how these drugs work, armed with this new information it could be possible to develop novel drugs targeting these complexes which may offer differentiated pharmacology and therapeutic index for treating disease," he said.

Importantly on this front, Professor Huntington's team were able to show that IKAROS had a conserved role in healthy B cells and thus potentially B cell cancers.
