[T-lymphocyte subpopulations in old age].
The subpopulation of lymphocytes were studied in 25 subjects old age and in 20 adult subjects as control. The results demonstrate an appreciable difference in the percentage of rosettes values at +4 degrees C for 18 hours between the old age subjects (mean value 83,5%) and the control subjects (mean value 66,2%). It is difficult to interpret these variations but it is possible that there is a different distribution on the cell membrane of lymphocyte T for the receptors for SRBC. The probable relation ship with variations of the citoskeleton and more specifically the distribution of the "Tubuline".
