Changes in immunological parameters by ageing in rural healthy Indian adults and their associations with sex and lifestyle.

ABSTRACT: Several factors including sex and lifestyle have been reported to contribute to the age-related alteration of immune functions. The study was undertaken to determine age-related differences in the proportion of peripheral blood mononuclear lymphocytes in the Indian population using blood samples from 67 healthy adults (33 females and 34 males) aged between 20 and 80 years old. In the linear regression analysis to estimate the relationship with age categories, there was a significant increase in the frequency of natural killer cells with ageing, while their cytolytic activity significantly declined. The frequency of CD4⁺ T cells increased with age, whereas that of CD8⁺ T cells decreased, resulting in the age-associated increase of the CD4/CD8 ratio. The subsets of B ce
