The present study was designed to investigate the immunomodulatory activity of the ethanolic extract of Tinospora cordifolia (Family: Menispermaceae) stem (climbing shrub, mango plant) at cellular level. For antioxidant study, the liver mitochondria were separated and the concentration of enzymes like lipid peroxidation (LPO), reduced glutathione (GSH), catalase (CAT) and superoxide Dismutase (SOD) were estimated; melatonin secretion characterization was carried out through SDS-PAGE. The spleen lymphocyte proliferation assay was performed through measuring its optical density at 570 nm using Elisa Reader. The cytokines viz. IL-2, IL-10 and TNF-α expression in spleen cells were determined through Real Time PCR. Tinospora cordifolia (Tc) ethanolic extract (100 mg/Kg/p.o.) increased the level of liver mitochondrial enzymes like GSH, CAT and SOD but decreased the level of LPO in liver as compared to the vehicle, SRBC and cyclophosphamide-treated groups. The secretion of melatonin via pineal gland was enhanced with Tc treatment. The extract also increased the spleen lymphocyte proliferation. In RT-PCR analysis, the expression of cytokines viz. IL-2, IL-10 and TNF-α was more in Tc-treated animals than vehicle and cyclophosphamide treatment. Hence, the study confirms the immunomodulatory activity of Tc stem through altering the concentration of antioxidant enzymes, increasing T and B cells and antibody which play an important role in immunity, enhancing the concentration of melatonin in pineal gland and increasing the level of cytokines like IL-2, IL-10 and TNF-α which plays an important role in immunity.
