A study conducted by international scientists has found that the capacity to resist or recover from infections and inflammation, known as "immune resilience," plays a significant role in determining an individual's health and lifespan. The researchers measured immune resilience through the relative quantities of CD4+ and CD8+ T cells, as well as gene expression signatures. Those with optimal immune resilience were more likely to live longer, resist infections, and survive diseases such as COVID-19 and sepsis. However, immune resilience can fluctuate, and aging can impact a person's ability to recover. Assessing immune resilience could have important public health implications in identifying disease risk, treatment response, and recovery potential.
A team of geneticists found evidence that the "Viking disease" hand disorder may have come from Neanderthal genes. Google DeepMind achieved a giant leap forward in sorting speed, and Google Research developed StyleDrop, an AI-based application that renders images based on user descriptions of objects. Archaeologists in Peru examined a mummy surrounded by coca leaves, and a team in Bavaria found a Bronze Age sword. Health scientists found that people who preserve their "immune resilience" tend to live longer and resist infections compared to everyone else.
Researchers from The University of Texas Health Science Center at San Antonio have developed a unique set of metrics to quantify the level of immune resilience, which is the capacity to resist or recover from infections and other sources of inflammatory stress. The laboratory tests developed to assess levels of immune resilience were evaluated in nearly 50,000 persons of differing ages and types of challenges to their immune systems. The researchers found that individuals with optimal levels of immune resilience were more likely to live longer, resist HIV and influenza infections, resist AIDS, resist recurrence of skin cancer after kidney transplant, survive COVID-19 infection, and survive sepsis.
