摘要

In an objective to find out an effective, nontoxic dendritic cell (DC) maturating agent for human use, CD14+ monocytes were differentiated with GMCSF/IL-4 and matured with neem leaf glycoprotein (NLGP). NLGP matured DCs (NLGP-DCs) show upregulated expression of CD83, CD80, CD86, CD40 and MHCs, in a comparable extent of control, LPS. NLGP-DCs secrete high amount of IL-12p70 with low IL-10. NLGP upregulates the expression of crucial transcription factor, ikaros, indicating maturation towards DC1 phenotype. Increased expression of CD28 and CD40L on T cells following co-culture with NLGP-DCs was noticed to promote DC-T interactions. As a result, T cells secrete high amount of IFN gamma with low IL-4 and generates anti-tumor type 1 immune microenvironment. Such NLGP-DCs present carcinoembryonic antigen (CEA) effectively to T cells to increase T cell mediated cytotoxicity of CEA+ tumor cells in vitro and in vivo. With emergence of the NLGP as a promising DC maturating agent, NLGP-DCs can be used as a candidate vaccine tool for antigen specific cancer immunotherapy.
