ABSTRACT
Available data on the normal levels of white blood cell populations in healthy rhesus macaques (Macaca mulatta) originated and living in China is scanty. To obtain such data, blood samples from 150 Chinese rhesus macaques were collected and the normal range of white blood cells and their subsets were analyzed according to age and sex by flow cytometry. CBC data showed that the count of total white blood cells and lymphocytes decreased with age. Phenotypic analysis of CD4 and CD8 expression on CD3+ T lymphocytes showed that the percentage of CD4+ T cells (51.4+/-9.6%), CD4-CD8- T cells (8.5+/-4.1%) and the ratio of CD4+ T to CD8+ T cells (1.26+/-0.55) decreased with age; and the percentage of CD8+ T cells (42.0+/-9.7%), CD4+CD8+ T cells (1.3+/-0.9%) and CD3+ lymphocytes (55.3+/-13.3%) increased with age. However, no statistically significant difference was observed between the male and female groups in most parameters in these monkeys except for the percentage of CD4+CD8+ T cells. This study provided basic information about blood cell count and T lymphocyte subsets in Chinese rhesus macaques. It may be useful for comparative studies using Indian and Chinese rhesus macaques.
