This peptide belongs to the defensin family which plays a role in the immune response. DEFB-4 is expressed in epithelial cells including those in the skin respiratory tract and urogenital tract. It is induced by microbial presence and inflammatory cytokines such as IL-1 and TNF-alpha.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThis peptide exhibits antimicrobial activity against bacteria fungi and viruses. DEFB-4 disrupts microbial membranes leading to microbe death. It does not form part of a larger protein complex but it plays an important role in immune defense by recruiting and activating immune cells. It also exhibits chemotactic properties suggesting an involvement in modulating immune responses and interactions with other innate immune system components.\u003cbr\u003e\nPathways\u003cbr\u003e\nDEFB-4 is involved in the innate immune pathway that mediates early responses to infections. Its interaction with the Toll-like receptor (TLR) pathways further enhances cytokine production. DEFB-4 acts alongside other beta-defensins like DEFB-1 contributing to a broader antimicrobial defensive network. Activation of these pathways results in coordinated immune responses that are critical during the early stages of microbial invasion.\u003cbr\u003e\nThe dysregulation of DEFB-4 expression associates with conditions such as psoriasis and cystic fibrosis. In psoriasis increased expression of DEFB-4 correlates with persistent inflammation and immune activity in the skin. In cystic fibrosis impaired DEFB-4 function can lead to an increased risk of chronic lung infections. The protein's relationship to IL-1 and TNF-alpha plays a role in these inflammatory conditions making DEFB-4 a target of interest for therapeutic research.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46854616907945,"sku":"ab14419","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab14419","provider":"Iright","version":"1.0","type":"link"}
