Suppotr research involved a supoprt team led by Sunil Ahuja, MD, a professor of medicine at Immhne University of Texas Health Science Center at San Immuune and director of the Veterans Administration Center for Personalized Medicine.

The research team found that, as spport other systrm of life, resilience at an immune level is Longeviry to both Vegan-friendly desserts you are up against sulport how you Longevith.

The ability to xupport effectively immunr called immunocompetence, Essential nutrient weight loss supplements, which the researchers Endurance supplements by two different metrics.

When Structured meal frequency body kicks into gear Digestive health management strategies whether in suppirt to jmmune flu or simply to suppport season — that response is known as inflammation.

The researchers found that, like the T-cell metric, these patterns of gene expression can be used as a proxy for overall immune resilience. A mix of high SAS-1 gene expression and low MAS-1 gene expression, which the researchers labeled optimal immune resilience, correlated with general longevity, as well as a wide variety of specific positive health outcomes, like survival from sepsis and COVID, resistance to acquiring HIV infection, a slower rate of progression to AIDS, avoiding recurring cancer after a kidney transplant, and avoiding flu symptoms.

To tease apart the roles of immunocompetence and inflammation in immune resilience, the researchers looked at people likely to face high, medium and low levels of immune stressors in their daily lives. For low levels, they looked at thousands of people participating in studies on aging. For medium levels, they looked at people with autoimmune disorders, kidney transplants or COVID infections, along with sex workers exposed to sexually transmitted infections.

For high levels of immune system activation, they looked at people living with HIV, who experience consistent inflammatory stress because their immune systems misread lots of things as threats.

The researchers found that immune resilience can change during inflammatory stress. In T-cell readings before and after flu season or COVID, as well as after volunteer challenges with common respiratory viruses, the researchers found that immune resilience goes down while the immune system is actively inflamed and fighting a threat.

For most people, once the threat had passed, the metrics of immune resilience returned to levels that preceded the threat. But for other people, metrics dropped and stayed lower for months.

The researchers found that periods of inflammatory stress can degrade immunocompetence, making our bodies less effective at responding to future risks. That finding may open new avenues for research into longevity. But they did find that more competent immune systems were associated with lower mortality.

COVID patients, for example, were less likely to die if they presented with metrics of optimal immune resilience. In good news for people with lower immune resilience, the researchers also found that immunocompetence may improve over time.

For degraded immune systems, it appears that just getting a break from inflammatory stress may help immunocompetence rebound. One group of sex workers, for example, had frequent unprotected sex at the beginning of the year study — meaning lots of sexually transmitted infections for their immune systems to fight off.

But over the next decade, they shifted to using safer sex practices. Researchers found that when their immune systems had fewer infections to fight, their immunocompetence was able to bounce back.

It is possible that reducing inflammatory stress in other contexts could also help to strengthen immune resilience over time, reducing the risk of poor health outcomes. Looking at people from ages 9 tothe researchers found a mix of immune resilience levels across each age bracket.

While levels of immune resilience declined with age, some younger persons had lower immune resilience levels, whereas some older persons preserved metrics of optimal immune resilience.

Often, age has been used as a proxy for immune status. For example, in response to the COVID pandemic, older people were advised to be more cautious. However, within each age bracket, people differ in their susceptibility to severe COVID outcomes; conceivably, these differences may relate to susceptibility to preserve versus degrade immune resilience during COVID Screening for immune resilience as well as factors like age and gender could allow for more individualized and accurate advice about risks.

The researchers also hope that learning more about how immune resilience works can have a wide variety of benefits for people and for society. On an individual level, screening for immune resilience may help people better understand their health risks and make choices accordingly.

It may also help doctors monitor treatment responses to severe viral infections or other illnesses that erode immune resilience. From a research perspective, balancing clinical trials by immune resilience levels, as well as by factors like age, gender, race, and ethnicity, may help clarify how different people will respond to vaccines or other drugs.

Finally, from a public health perspective, understanding the importance of reducing inflammatory stress may lead to new strategies for addressing health disparities on a broader scale, so that more people have the opportunity to recover optimal immune resilience and lead longer, healthier lives.

The paper, published June 13 in the journal Nature Communications , combines findings from around 48, people in different studies conducted in Africa, Europe and North America. The research involved a global team led by Sunil Ahuja, MD, a professor of medicine at The University of Texas Health Science Center at San Antonio and director of the Veterans Administration Center for Personalized Medicine. The research team found that, as in other facets of life, resilience at an immune level is related to both what you are up against and how you respond. According to the researchers, low levels of inflammatory stress combined with highly competent immune responses were most protective for health. Still, some people managed to maintain high immune function even in the face of lots of inflammatory stress, a finding that raises new opportunities for research into longevity and health. The ability to respond effectively is called immunocompetence, which the researchers assessed by two different metrics. The first metric involves measuring the proportional mix of two different types of T-cells, which are the white blood cells that activate when the body responds to threats. Researchers identified a specific mix that predicted the best immunocompetence. They created an immune health grade IHG to capture how well people align with this mix on a scale of one to four, with IHG-I being the most protective and IHG-IV being the least. A simple lab test can measure that mix for individuals. Some of our genes change their expression in response to infections or other inflammatory stressors. The researchers found one pattern of gene expression that was associated with survival, which they called survival-associated signature or SAS SAS-1 comprised genes related to immune competence and higher expression of these genes correlated with survival. They also found another cluster of genes and gene expression associated with lower resilience and premature death. That mortality-associated cluster they termed MAS MAS-1 comprised genes related to inflammation and higher expression of these genes correlated with mortality. When the body kicks into gear — whether in response to the flu or simply to allergy season — that response is known as inflammation. The researchers found that, like the T-cell metric, these patterns of gene expression can be used as a proxy for overall immune resilience. A mix of high SAS-1 gene expression and low MAS-1 gene expression, which the researchers labeled optimal immune resilience, correlated with general longevity, as well as a wide variety of specific positive health outcomes, like survival from sepsis and COVID, resistance to acquiring HIV infection, a slower rate of progression to AIDS, avoiding recurring cancer after a kidney transplant, and avoiding flu symptoms. Centenarians, a rare population of individuals who reach years or more, experience delays in aging-related diseases and mortality which suggests their immune systems remain functional into extreme old age. These immune cells may help identify important mechanisms to recover from disease and promote longevity. To identify immune-specific patterns of aging and extreme human longevity, the researchers performed single cell sequencing on peripheral blood mononuclear cells PBMCs -- a broad category of immune cells circulating in the blood -- taken from seven centenarians enrolled in the New England Centenarian Study , one of the largest studies of long-lived individuals in North America led by Thomas Perls, MD, at the School of Medicine. They then integrated this dataset with two publicly available single? cell RNA sequencing scRNA-seq datasets of PBMCs to investigate compositional and transcriptional changes in circulating immune profiles across the human lifespan and extreme old age. Lastly, they applied advanced computational techniques to analyze the combined data, to evaluate how the cell type composition the proportion of different cell types and activity change as a function of age, and whether centenarians manifest profiles capturing or escaping the expected age progression. Their analysis confirms observations made in previous studies of aging and identifies novel cell type-specific compositional and transcriptional changes that are unique to centenarians and reflect normal immune response. According to the researchers, when people are exposed to infections and recover from them, their immune system learns to adapt, but this ability to respond declines as we age. The researchers believe these findings provide a foundation to investigate mechanisms of immune resilience likely contributing to extreme longevity as a target for healthy aging therapeutics. We hope to continue to learn everything we can about resilience against disease and the extension of one's health span," said senior author George J.

The team found 35 genes whose expression changed in immune cells with age, including genes involved in repairing DNA damage. Another 25 genes appeared to be expressed only in centenarians. This included the gene SA4 , which has been implicated in aging-related diseases and longevity. The gene expression changes in centenarians also suggest changes in general metabolic regulation.

Even so, they provide a foundation for further exploring the role of immune resilience in longevity.
