Abstract

Characterization of immune cell subpopulations in the cynomolgus monkey was performed using a direct immunofluorescence technique adaptable for routine and repeated monitoring. This whole blood procedure is faster and requires less volume than conventional density gradient isolation methods. Low intra- and inter-animal variations were seen in hematology parameters and in CD4, CD8, and CD20 lymphocyte subtypes. CD4 values were 28% of lymphocytes in males and 30% in females. Fifty-six percent were CD8+ in males and 54% in females. CD4:CD8 ratios were approximately 0.5 in both sexes. This proportion is the reverse of that observed in humans, but appears normal for the cynomolgus. Consistent with values reported for humans, approximately 12% of cynomolgus peripheral blood lymphocytes were CD20+. Greater than 95% of the lymphocytes present in blood were identified as CD4, CD8, or CD20 positive.
