Abstract

Immunological T cells and associated cytokines have been shown to be involved in the pathogenesis of multiple myeloma (MM). However, the abnormal immune imbalance of T lymphocyte subsets on MM remains unknown. We investigate the proportions of T helper 1 (Th1)/Th2/Th17/T regulatory (Treg) cells in peripheral blood mononuclear cells (PBMCs) by flow cytometry (FCM), and serum levels of relevant cytokines in MM patients and controls were detected by enzyme-linked immunosorbent assay (ELISA). The messenger RNA (mRNA) expression of T-bet, STAT6, RORgammat, and Foxp3 was measured by real-time quantitative polymerase chain reaction (PCR). The CD4+ Th1 and CD4+ Th17 cells in patients with MM were significantly higher than those in health controls as well as the expression of T-bet and RORgammat mRNA. Furthermore, serum levels of interferon gamma (IFN-γ), IL-6, and IL-17A in MM group were greatly increased and significantly associated with each other. Significant differences on Th cells, cytokines, and transcription factors were observed on MM patients. The imbalance of T lymphocyte subsets was thought to contribute to the pathogenesis and underlying mechanisms of MM.
