PIgT

PIgT, also known as pigtailed transglutaminase, is an enzyme that has been studied for its potential therapeutic applications. This enzyme is a modified form of transglutaminase 2 (TG2), a naturally occurring enzyme in the human body that plays a role in various cellular processes, including cell adhesion, wound healing, and apoptosis. The "pigtailed" modification refers to the addition of a short peptide sequence to the enzyme, which is believed to enhance its stability and delivery.

Research into PIgT has primarily focused on its potential to treat fibrotic diseases. Fibrosis is a condition characterized by excessive scar tissue formation, which can impair the function of organs such as the liver, lungs, and kidneys. PIgT has been shown in preclinical studies to reduce collagen deposition and inflammation, key components of fibrotic tissue. This suggests that PIgT could offer a novel therapeutic strategy for conditions like idiopathic pulmonary fibrosis and liver cirrhosis.

Furthermore, PIgT is being investigated for its role in other conditions where TG2 activity is implicated, such as certain cancers and neurological disorders. The precise mechanisms by which PIgT exerts its effects are still under investigation, but it is thought to involve modulating TG2 activity and influencing extracellular matrix remodeling. While promising, PIgT is still in the early stages of research and development, and further clinical trials are needed to establish its safety and efficacy in humans.
