PG - 186-94 AB - This study shows that characteristic dendritic, antigen presenting cells, can be generated from adherent peripheral blood mononuclear cells (PBMC)/monocytes of uninfected and SIVsm-infected cynomolgus monkeys after stimulation in vitro with granulocyte macrophage colony stimulating factor (GM-CSF) and interleukin (IL)-4. The recruitment of monocyte derived dendritic cells (MDDC) was usually possible irrespective of the level of immunodeficiency (CD4-level) and viremia. The cynomolgus MDDC closely resembled their human counterpart (immature MDDC) with regard to capacity to upregulate CD1a, CD40, CD86 and human leukocyte antigen (HLA)-DR and develop dendrites and veiled processes. Such MDDC also increased their capacity for antigen uptake (dextran endocytoses/macropinocytosis) and for induction of T-cell proliferation in mixed leukocyte reaction (MLR) assays. However, although no clear difference with regard to phenotype and morphology was seen between MDDC from SIV-infected and uninfected monkeys, a reduction in MLR responsiveness in MDDC from SIV infected monkeys was consistently detected within each experiment.
