title: Influence of physical activity stress and age on the ADCC of lymphocytes from mice.
abstract: The influence of physical activity stress (swimming until exhaustion) and age on the antibody-dependent cellular cytotoxicity (ADCC) of lymphocytes from spleen, thymus and axillary lymph nodes in BALB/c mice was studied. The results indicate that the ADCC activity decreases after the acute stress both in young and in old mice. However, when swimming until exhaustion is performed after 1 month training, the ADCC activity increases except in the case of spleen lymphocytes from old mice. The basal ADCC capacity of spleen lymphocytes from old controls is higher (P<0.05) than from young controls, but there are no statistically significant differences in this respect between young and old animals in lymphocytes from thymus and axillary lymph nodes. No correlations between the increase in serum corticosterone levels and ADCC response are found.
