Previous studies have shown that the CC chemokine receptor CCR5 is downregulated on monocyte/macrophage(MO/Mw)surfaces in head and neck squamous cell carcinoma(HNSCC)patients(stage IIIB).Ligands(RANTES,MIP-1a and MIP-1b)of this chemokine receptor were also secreted in lesser quantity from MO/Mw of HNSCC patients in comparison with healthy *** an aim to restore this dysregulated receptor–ligand signaling,we have used neem leaf glycoprotein(NLGP),a novel immunomodulator reported from our *** upregulated CCR5 expression,as evidenced from studies on MO/Mw of peripheral blood from HNSCC patients as well as healthy *** of RANTES,MIP-1a and MIP-1b was also upregulated following NLGP treatment of these cells in ***,NLGP has little effect on the expression of CCR5 and the ligand RANTES in oral cancer *** restored CCR5 receptor–ligand signaling seen in MO/Mw was reflected in improved CCR5-dependent,p38 mitogen-activated protein kinase(MAPK)-mediated migration of MO/Mw after NLGP treatment to a standard *** also induces better antigen presentation and simultaneous costimulation to effector T cells by MO/Mw by upregulating human leucocyte antigen(HLA)-ABC,CD80 and *** addition,NLGP-treated MO/Mw-primed T cells can effectively lyse tumor cells in *** effects of NLGP on monocyte migration and T cell-mediated oral tumor cell killing were further demonstrated in transwell assays with or without CCR5 *** results suggest a new approach in cancer immunotherapy by modulating dysregulated CCR5 signals from MO/Mw.
