We have developed a method for isolating and characterizing pigtailed macaque dendritic cells (DCs) generated from CD34(+) bone marrow (BM) progenitors based on methods previously developed for isolating human DCs. Macaque DCs displayed a characteristic morphology and were potent stimulators of allogeneic T cell proliferation. They expressed a set of DC-associated markers, such as MHC class II, CD1a, CD4, CD11a, CD40, CD58, CD80, CD83, CD86, and CXCR4. Macaque DCs, as well as peripheral blood CD4(+) T cells, were highly susceptible to HIV-2 infection, as detected by DNA-PCR. The expression of HIV-2 in macaque DCs was downregulated by treatment with the beta-chemokine RANTES. Macaque DCs will be useful for defining the in vivo role of DCs in HIV pathogenesis and for optimizing and testing peptide-DC vaccines or tolerizing regimens.

D003713 Dendritic Cells Specialized cells of the hematopoietic system that have branch-like extensions. They are found throughout the lymphatic system, and in non-lymphoid tissues such as SKIN and the epithelia of the intestinal, respiratory, and reproductive tracts. They trap and process ANTIGENS, and present them to T-CELLS, thereby stimulating CELL-MEDIATED IMMUNITY. They are different from the non-hematopoietic FOLLICULAR DENDRITIC CELLS, which have a similar morphology and immune system function, but with respect to humoral immunity (ANTIBODY PRODUCTION).
