Inflammatory bowel disease (IBD) is an idiopathic chronic inflammation of the gastrointestinal tract which is mainly caused by dysregulated gut immune response to commensal flora. Very limited treatment options with marginal efficacy are available along with surgery which has high risk of reoccurrence. As both innate and adaptive immune responses have been found altered in IBD, a good therapeutic strategy could be to restrict both of them under chronic inflammatory conditions. Effect of chloroquine on TLR9 signaling is well reported, while there are limited studies on non-endosomal TLRs as well as T cell responses. Hence, we studied its effect on other TLRs as well as T cell response along with testing it as a potential therapeutics in IBD using murine preclinical colitis model. Chloroquine significantly suppressed the TLR2 as well as TLR9 signaling in both in vitro as well as in vivo experimental settings, while it had no effect on TLR4 pathway. It also suppressed the T cell cytokine and proliferative responses. In, DSS-induced murine colitis model, chloroquine administration, significantly improved body weight loss, colon length shortening, tissue damage and inflammatory cell infiltration. Based on our findings in preclinical murine model of IBD, chloroquine has the potential to be considered as a therapeutic option in clinics through inhibition of diverse TLR and T cell responses.
