Toll like receptors play an important role in innate and adaptive immune responses. Heat shock proteins play a significant role in cell proliferation, differentiation and oncogenesis. HSP70 acts as one of the ligands of TLR4 and binds to it in a CD14 dependent fashion to bring about proinflammatory cytokine production leading to an anti-tumor response. On the contrary, TLR4 has been implicated in carcinogenesis by secretion of anti-apoptotic proteins. Thus the aim of this study was to compare and correlate the association of HSP70 and TLR4 in various grades of oral squamous cell carcinoma.
