Özet:
Myelosuppression and gastrointestinal damage are common side effects of cancer treatment limiting efficacy of DNA-damaging chemotherapeutic drugs. The Toll-like receptor 5 (TLR5) agonist, Entolimod, has demonstrated efficacy in mitigating damage to hematopoietic (HP) and gastrointestinal (GI) tissues caused by radiation. Here, using 5-Fluorouracil (5-FU) treated mice as a model of chemotherapy-induced side effects; I demonstrated significant reduction in the severity of 5-FU-induced morbidity. Increased survival was accompanied by the improved integrity of intestinal tissue and the restoration of hematopoiesis in Entolimod treated mice. Entolimod-stimulated IL-6 production was essential for Entolimod's ability to rescue mice from death caused by doses of 5-FU associated with HP failure. In contrast, IL-6 induction was not necessary for protection and restoration of drug-damaged GI tissue by Entolimod. In a syngeneic mouse CT26 colon adenocarcinoma model, Entolimod reduced the systemic toxicity of 5-FU, but did not reduce its antitumor efficacy indicating that the protective effect of Entolimod was selective for normal, noncancerous tissues. These results suggest that Entolimod has clinical potential to broaden the therapeutic window of genotoxic anticancer drugs by reducing their associated HP and GI toxicities.
