Membrane microviscosity was assessed by a fluorescence polarization technique in fresh and precultured human peripheral blood lymphocytes of young and old subjects. Membrane microviscosity was significantly higher in fresh, non-treated cells of old donors as compared to young adults. Preincubation of cells in culture medium supplemented with pooled human serum diminishes the original microviscosity difference between the age groups. The observed increase in membrane fluidity correlates with the improvement of the mitogen-induced proliferative response due to preculturing cells from aged subjects. The results support the suggestion that membrane microviscosity can affect the proliferative response of lymphocytes, and it may play a role in the decline of the immune responsiveness in the elderly.
