The DEFB1 antibody targets human beta-defensin 1 (DEFB1), a small antimicrobial peptide encoded by the DEFB1 gene. DEFB1 is part of the defensin family, which plays a critical role in innate immunity by providing rapid defense against pathogens, including bacteria, viruses, and fungi. It is constitutively expressed in epithelial tissues, such as the skin, respiratory tract, and urogenital system, and is regulated by inflammatory signals or microbial exposure. DEFB1 disrupts microbial membranes and modulates immune responses by attracting immune cells via chemotactic activity.
DEFB1 antibodies are essential research tools for studying its expression, localization, and function in health and disease. They are used in techniques like immunohistochemistry, Western blotting, and ELISA to investigate DEFB1’s role in infections, inflammatory disorders (e.g., psoriasis, cystic fibrosis), and cancer. Some studies suggest altered DEFB1 levels correlate with disease susceptibility or progression.
These antibodies are typically produced in hosts like rabbits or mice, either as polyclonal or monoclonal forms. Challenges include ensuring specificity due to sequence homology among defensins and optimizing detection in diverse biological samples. Research on DEFB1 continues to explore its therapeutic potential, including as a biomarker or a template for antimicrobial drug design.
