The activation of the host cell immune system upregulates the production of inflammatorymediators,comprisingcytokinesandproteolyticenzymes,whichcontributetoinflammationandbonedestruction.Ithasbeenwellknownthatperiodontitisisrelatedtosystemicinflammationwhichlinkstonumeroussystemicdiseases,includingdiabetesandarteriosclerosis.Furthermore,periodontitishasbeenreportedinassociationwithneurodegenerativediseasessuchasAlzheimer’sdisease(AD)inthebrain.Regardingimmuneresponsesandinflammation,cathepsinB(CatB)playspivotalrolefortheinductionofIL-1β,cathepsinK-(CatK-)dependentactivetoll-likereceptor9(TLR9)signaling,andcathepsinS(CatS)which involves in regulating both TLR signaling and maturation of the MHC class II complex. Notably, both the production and proteolytic activities of cathepsins are upregulated in chronic inflammatory diseases, including periodontitis. In the present review, we focus on the roles of cathepsins in the innate and adaptive immune responses within periodontitis. We believe that understandingtherolesofcathepsinsintheimmuneresponsesinperiodontitiswouldhelptoelucidatethetherapeuticstrategies of periodontitis, thus benefit for reduction of systemic diseases as well as neurodegenerative diseases in the global aging society..
