Inhibition of the delayed-type hypersensitivity response by staphylococcal enterotoxin B-induced suppressor T cells.

abstract：:CCR5 is a chemokine receptor expressed by T cells and macrophages, which also functions as the principal coreceptor for macrophage (M)-tropic HIV-1 strains to enter the host cells. In this study, we aim to better understand the ligand-binding profiles of CCR5 and the chemokine-receptor usage on leukocyte cells. We fou...
