DEFB130 recombinant protein is derived from the human DEFB130 gene, which encodes a member of the β-defensin family. Defensins are small, cationic antimicrobial peptides integral to innate immunity, exhibiting broad-spectrum activity against bacteria, viruses, and fungi. The DEFB130 gene is located on chromosome 8p23.1. a region densely populated with defensin genes, and is primarily expressed in epithelial tissues, including the respiratory, gastrointestinal, and urogenital tracts. Its expression is often modulated by microbial exposure or inflammatory signals, suggesting a role in mucosal defense.
Structurally, DEFB130 contains six conserved cysteine residues forming three disulfide bonds, a hallmark of β-defensins that stabilizes its β-sheet-rich fold. This compact structure enables interaction with microbial membranes, disrupting their integrity via electrostatic attraction to negatively charged pathogens. Beyond direct antimicrobial effects, DEFB130 may also act as a chemokine, recruiting immune cells by binding to chemokine receptors like CCR6. thus bridging innate and adaptive immunity.
Recombinant DEFB130 is produced using expression systems such as *E. coli* or mammalian cells, followed by purification via chromatography. Its recombinant form allows researchers to study its therapeutic potential in infections, chronic inflammation, or cancer immunotherapy. However, challenges persist, including optimizing stability, minimizing cytotoxicity, and understanding tissue-specific functions. Current research focuses on its role in microbiota interactions, wound healing, and as a biomarker for inflammatory diseases. Despite promising attributes, DEFB130's precise mechanisms and clinical applicability remain under active investigation.
