A study by Monash Biomedicine Discovery Institute (BDI) expands the understanding of the molecular pathways that control T cell function and survival and how it relates to declining T cell immunity in the elderly.
The findings, published in Nature Communications, led by Monash BDI’s Professor Nicole La Gruta and Dr. Kylie Quinn (formerly of Monash University BDI, now Vice-Chancellor’s Research Fellow at RMIT University), outline that the increased metabolism of T cells observed with advanced age was an indication that they were working harder merely to survive.
This contradicts previous knowledge, which suggested an increased metabolism was indicative of T cell function, and will have implications for the development of targeted interventions such as vaccines or immunotherapies to treat age-related immune dysfunction.
