SAP (secretory antimicrobial peptide)

Secretory Antimicrobial Peptides (SAPs) are small proteins produced by our body's cells, especially at mucosal surfaces like the skin and lining of the gut. They serve as a first line of defense by directly attacking and neutralizing harmful bacteria, fungi, and viruses. SAPs operate by disrupting the outer structures of these pathogens, preventing infections. They are part of the innate immune system, providing rapid, localized protection without the need for prior exposure. Overall, SAPs play a crucial role in maintaining our health by helping to keep harmful microorganisms in check at vulnerable entry points.
