Introduction: The Cuban population has a high proportion of older adults and faces age-related changes in the immune system, known as immunosenescence. Natural Killer T (NKT) cells and Natural Killer (NK) cells play an important role in innate immunity and modulating adaptive immune responses. Their diminished function in older adults contributes to increased susceptibility to infectious diseases, tumors and autoimmune diseases in this population group.
Objective: To characterize distribution of NKT and NK cells in Cuban older adults.
Method: A cross-sectional study was carried out in 30 Cuban older adults, considering age, sex and malignant neoplasm comorbidity as factors of influence on the values of NK and NKT. A linear regression model was used to analyze the data, as well as a two-tailed Mann-Whitney U test to.. View More»
