摘要: The development of Ia + dendritic cells (DCs) in the aqueous outflow pathways and iris rat eye may occur more slowly than that observed other tissue sites. It appears DCs infiltrate primordium as Ox62 /Ia - or lo precursor cells, which subsequently develop situ into bearing high levels antigen. purified by positive immunomagnetic selection have functional capacity to stimulate naive T a mixed lymphocyte response (MLR) similar conventional DCs, such Langerhans (LCs). Iris like “immature” peripheral tissues, are weak antigen presenting (APCs), require appropriate cytokine maturational signals, GM-CSF order display potent stimulatory an MLR assay. In eye, retinal pigment epithelium (RPE) also known release GM-CSF, is survival factor for DCs. Production RPE induced cytokines TGFβ, TNFα, IL-1.
