RP-832c

RP-832c is a synthetic analogue of host defense peptides (HDP), targeting the mannose receptor CD206 on the surface of M2 polarized macrophages (Kd = 3.5 μM) . RP-832c binding to CD206 induces a significant conformational change in the receptor, activating signaling pathways that lead to rapid apoptosis and repolarization of CD206-positive M2 macrophages to an M1 phenotype. RP-832c treatment significantly reduces CD206 gene expression in M2 macrophages while transiently increasing expression of TNF-α, a marker for M1 macrophages. RP-832c is used for the studies of T-cell lymphoma (CTCL) and idiopathic pulmonary fibrosis (IPF) [1][2].
