title: Immunomodulatory and antitumor actions of medicinal plant Tinospora cordifolia are mediated through activation of tumor-associated macrophages.
abstract: The present investigations were under taken to study whether the tumor-associated macrophages (TAM) of Dalton's lymphoma (DL), a spontaneous transplantable T cell lymphoma, can be activated by the alcoholic extract of medicinal plant Tinospora cordifolia (ALTC). Intraperitoneal administration of ALTC in DL-bearing mice not only augments the basic function of macrophages such as Phagocytosis as well as their antigen presenting ability and secretion of IL-1, TNF and RNI. The results of the present investigation also indicate that the intraperitoneal administration of ALTC slow down the tumor growth and increases the life span of tumor bearing host, thus showing its anti tumor effect through destabilizing the membrane integrity of DL cells directly or indirectly. This is the first study of it's kind regarding the effect of alcoholic extract of Tinospora cordifolia on the activation of tumor associated macrophages and showing the antitumor effect on the spontaneous T-cell lymphoma (DL), thus may have clinical implications.
