CALPAIN ACTIVITY MAINTAINS GOOD HEALTH OF CENTENARIAN T CELLS; SUMMARY OF THE CALPACENT PROJECT
2017
Causes of aging-associated deterioration of human immunity, and the reasons why the immune system of the oldest old individuals (centenarians) is relatively robust, remain moot. Intracellular proteolysis system of two proteases – µ- and m-calpain – and their inhibitor – calpastatin (the calpain-calpastatin system (CCS)) - is active in resting human peripheral blood T cells, participating in maintenance of their readiness to proliferate and secrete cytokines in response to stimulation. The amounts of the CCS proteins decrease in resting T lymphocytes of healthy elderly, only to return in the centenarians to those levels seen in the young individuals. We compared the calpain activities and th…

Abstract Background Ubiquitous system of regulatory, calcium-dependent, cytoplasmic proteases – calpains – and their endogenous inhibitor – calpastatin – is implicated in the proteolytic regulation of activation, proliferation, and apoptosis of many cell types. However, it has not been thoroughly studied in resting and activated human lymphocytes yet, especially in relation to the subjects’ ageing process. The CALPACENT project is an international (Polish-Italian) project aiming at verifying the hypothesis of the role of calpains in the function of peripheral blood immune cells of Polish (Pomeranian) and Italian (Sicilian) centenarians, apparently relatively preserved in comparison to the g…
