β-defensin 134 アクチベーター

In general, β-defensins are small, cationic peptides that exhibit broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses. They are characterized by the presence of six conserved cysteine residues that form three disulfide bonds, contributing to their stability and functional conformation. These peptides are predominantly expressed in epithelial cells of various tissues including the skin, respiratory tract, and urogenital tract, serving as a first line of defense against pathogens.

The mechanism of action of β-defensins involves the disruption of microbial cell membranes, which leads to the leakage of essential cellular contents and subsequent cell death. In addition to their direct antimicrobial functions, β-defensins also play a role in immune signaling by acting as chemotactic agents for immune cells, thereby assisting in the orchestration of the adaptive immune response.If "β-defensin 134" were to be a newly discovered member of the β-defensin family, it would likely share these characteristic features and functions. It would be a subject of interest to researchers aiming to understand its specific antimicrobial spectrum, expression patterns, and potential roles in disease and host defense mechanisms.
