Immune cell frequency in different rat strains over time from days 30 until 90 of life. The frequency of natural killer (NK) cells as well as the frequency of monocytes and B cells was measured in the different rat strains. For each time-point a mean value ± standard error of the mean (s.e.m.) was calculated for each group. Diabetic and non-diabetic LEW.1AR1-iddm rats showed more changes in the immune cell frequency over time (a,b) than the other strains. (d) = diabetic, (nd) = non-diabetic.
