In A First, Researchers Reveal That Killer T Cells In Older Adults Find It Difficult To Recognise Infected Cells

Killer T cells in older adults: This world-first discovery is significant because it will help researchers develop better vaccines and therapies.

The gene features of killer T cells found in older adults are similar to those of the killer T cells in newborn babies. However, since they are replaced with suboptimal cells, they have a decreased ability to recognise influenza viruses.

Australian researchers have revealed that killer T cells in older adults are similar to those found in neonates and children, but cannot recognise infected cells. This world-first discovery is significant because it will help researchers develop better vaccines and therapies. The study describing the findings was recently published in the journal Nature Immunology.  Scientists have studied killer T cells, also known as CD8 + T cells, for several years. While they are known to eliminate
