ABSTRACT
In order to effectively use cynomolgus monkeys as animal models for human diseases, more than 300 anti-human monoclonal antibodies (mAbs) were studied as to their cross-reaction with various antigens from cynomolgus monkeys (Macaca fascicularis). Two hundred twenty-nine of 339 (67.55%) anti-human mAbs that react with human antigens of CD-defined molecules, chemokine receptors, and T cell receptors were cross-reactive with the monkey antigens. Using the cross-reactive antibodies and the fluorescenced beads for calibration, the procedure for the absolute count of monkey lymphocyte subsets was developed and the mean values for CD4+ and CD8+ lymphocyte subsets in peripheral blood were 718 and 573/mm3, respectively. Moreover, intracellular cytokines, IL-2, IL-4 and IFN gamma, and intracellular apoptosis-related proteins, Bcl-2, FADD and active form of caspase-3 could be detected in peripheral blood mononuclear cells as well as various tissue cells. It is therefore practicable to detail the phenotype of leukocytes, assess the production of intracellular cytokines and enumerate T-lymphocyte subsets by using the cross-reactive human antibodies with respective antigens of cynomolgus monkeys.
