A synthetic peptide homologous to the envelope proteins of retroviruses inhibits monocyte-mediated killing by inactivating interleukin 1.


The synthetic peptide CKS-17 has homology to a highly conserved region of the immunosuppressive retroviral envelope protein P15E, to envelope proteins of HTLV I, II, III, and to that encoded by an endogeneous C-type human retroviral DNA. CKS-17 inhibits the immune response of lymphocytes and the respiratory burst of human monocytes. Because P15E-related… (More)
