Abstract:
Innate immune system forms the first line of defense against microbial infections, as it exerts an immediate response. Innate immunity works through Toll-like receptors (TLRs) which functions as primary sensors of pathogens. TLR activates multiple signaling cascades leading to the induction of genes responsible for the release of inflammatory cytokines and type I interferon. Thus, they induce antimicrobial responses and also have an instructive role in adaptive immunity. However, TLR-mediated inflammation is said to be responsible for many of the destructive host responses in inflammatory diseases like periodontitis. Hence, therapeutics targeting TLRs are being used to treat disease such as HIV, Hepatitis B, asthma etc. Recently, synthetic TLR agonists are tried as novel vaccine adjuvant in treating periodontal diseases. This paper reviews the scope of TLR-based therapeutics in treating periodontitis.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
