Biotech firms are targeting a US$610 billion longevity market to reverse aging by using AI to reprogram human cells, according to Beijing-based METiS TechBio CEO Lai Tsai-ta. The approach involves fixing errors in genetic code, such as DNA sequences, and potentially repairing immune cells like T cells to slow or reverse the aging process.

Biotech firms are targeting a US$610 billion longevity market to reverse aging by reprogramming cellular errors using AI. METiS TechBio CEO Lai Tsai-ta compares aging to software bugs in DNA and suggests AI could repair immune cells like T cells to slow or reverse the process.

Research published in Nature found that immune cells in the blood contribute to cognitive ageing, and blocking them can improve memory. The study involved old T cells secreting an enzyme that impairs brain function in mice. This discovery may lead to new treatments for age-related cognitive decline.

HIV-1 signalling remodels nuclear pores to licence infection by triggering receptor-mediated signalling during cell-cell spread. This process overcomes the bottleneck of HIV-1 capsid nuclear import at the nuclear pore complex, allowing for resting T cell infection. The study was published in Nature on May 6, 2026.

A world-first clinical trial using long-lived T cells that mimic stem cells achieved remission in some blood cancer patients. The study, published in Nature on April 30, 2026, highlights a promising new approach to cancer immunotherapy.

A study published in Nature reveals that eating breakfast may enhance T cell responsiveness, potentially boosting immunity. Additionally, the article discusses lessons from the 40th anniversary of the Chernobyl disaster to prevent future nuclear accidents.

A study published in Nature reveals that infection-fighting T cells from individuals who have recently eaten can proliferate more quickly in response to threats. The research suggests that eating primes immune cells for faster action against infections.

Scientists identified HOXD13 as a key protein that drives melanoma tumor growth and immune evasion by enhancing blood supply and suppressing cancer-fighting T cells. Disabling HOXD13 reduces tumors and restores immune system activity, offering a potential new treatment approach for skin cancer.

Scientists discovered blocking the Ant2 protein enhances T cells' energy generation, making them more effective against cancer. This breakthrough could revolutionize cancer immunotherapy by boosting the immune system's ability to target tumors.

Zeaxanthin, a common nutrient found in vegetables and supplements, may enhance cancer treatment by strengthening T cells and boosting immunotherapy. Scientists suggest it's safe and accessible, with human trials planned as the next step.

A study published in Nature reveals that nasal tissue contains T cells capable of remembering pathogens long after infection. These long-lived immune cells suggest potential implications for understanding immune memory and disease resistance.
