noun. de· fen· sin di-ˈfen (t)-sən. : any of a class of peptides that are found in neutrophils and have antimicrobial and cytotoxic properties.1 Introduction. Defensins are a group of antimicrobial peptides (AMPs) that are an essential part of the innate immune system. Because of their broad-spectrum …The role of defensins in human reproduction. Defensins are widely distributed along the male and female reproductive tracts. Sperm are produced from the testis, mature in the epididymis and enter the female reproductive tract for fertilization. (A) During the maturation in the epididymis, β-defensins are loaded onto the sperm surface.

Defensins are small (29–35 amino acids) proteins produced by circulating white blood cells and tissue cells. Defensins can be classified into alpha and beta families. Alpha-defensins (α-defensins) are found in neutrophils, macrophages, and Paneth cells in the intestine. ディフェンシン は、 脊椎動物 および 無脊椎動物 双方に見出される 正電荷 を持った タンパク質 （ オリゴ ペプチド ）である。. ディフェンシンは、 真正細菌 （バクテリア）・ 真菌類 ・ ウイルス ・ ウイロイド に対して活性を持つ 抗微生物ペプチド で ... Oct 15, 1999 · Thus, β-defensins may promote adaptive immune responses by recruiting dendritic and T cells to the site of microbial invasion through interaction with CCR6. Defensins, a family of small (3.5 to 4.5 kD) cationic antimicrobial peptides with three to four intramolecular cysteine disulfide bonds, are found in mammals, insects, and plants (1–4). Background β-defensins have attracted considerable research interest because of their roles in protecting hosts from various pathogens. This study was conducted to investigate the expression profiles of the porcine β-defensin 114 (PBD114) in different breeds and in response to infections. Moreover, the function of PBD114 protein was …

1. Introduction. Defensins are antimicrobial peptides known to protect the host through their direct or indirect activities on microbes [1–3], although recent studies have demonstrated their ability to promote viral infectivity [4,5], indicating a complex role of defensins in host defense in a microbe, defensin, cell-type specific manner. Purpose of review: Defensins are a major family of antimicrobial peptides expressed predominantly in neutrophils and epithelial cells, and play important roles in innate immune defense against infectious pathogens. Their biological functions in and beyond innate immunity, structure and activity relationships, mechanisms of action, and therapeutic …Defensins are widely distributed and abundant 3-4 kDa antimicrobial peptides that are variable cationic and contain six disulfide-paired cysteines. Three structurally distinct peptide families have been identified: 'classical' defensins, beta-defensins and insect defensins. In many animal species, d … ….
