Gingipains function
WebGingipains are a family of proteases secreted by Porphyromonas gingivalis. Among other functions, it works to degrade cytokines, thereby downregulating the host response in the form of reduced inflammation. Gingipain has been studied for its potential role in the development of Alzheimer's disease.
