prozis-collagen-peptides Psoriasin, a key antimicrobial peptide, plays a significant role in the human body's defense mechanisms, particularly in the skin and on mucosal surfaces.作者：M Peric·2009·被引用次数：191—Antimicrobial peptides(AMPs) are strongly expressed in lesional skin inpsoriasisand play an important role as proinflammatory “alarmins” in this chronic ... While its name is closely associated with psoriasis, a chronic inflammatory skin condition, psoriasin's function extends beyond this disease, acting as a crucial component of the innate immune system.Vitamin D Analogs Differentially Control Antimicrobial Peptide ... This protein is recognized for its potent antimicrobial activity, especially against certain bacteria like *Escherichia coli*, contributing to the first line of defense against microbial invasion.
Psoriasin, also known by its gene name S100A7, is a member of the S100 protein family. These proteins are characterized by their ability to bind calcium ions and often function in cellular processes such as cell growth, differentiation, and inflammation. In the context of immunity, psoriasin is a prominent example of an antimicrobial peptide (AMP)Microbicidal protein psoriasin is a multifunctional .... AMPs are small, naturally occurring molecules that exhibit broad-spectrum antimicrobial activity, making them essential for host defense作者：KH Kim·2009·被引用次数：8—Conclusion. Increasedpsoriasinin cholesteatoma epithelium may play a role in epithelial inflammatory response and differentiation.. Psoriasin is predominantly expressed by keratinocytes, the main cell type in the epidermis, and is also found in other epithelial tissues, including the tongue and ocular surfaceAccepted Manuscript. Its presence in these locations highlights its role in protecting the body from external pathogens.
The strong link between psoriasin and psoriasis stems from the observation that its production is significantly upregulated in the lesional skin of individuals with psoriasis. In psoriatic skin, keratinocytes overproduce antimicrobial peptides, including psoriasin.2014年2月28日—Abstract.Psoriasin(S100A7) anantimicrobial peptidewas associated with inhibition of Esherichia coli on palms but the role of ... While these peptides are part of the innate immune response, their dysregulated expression in psoriasis contributes to the inflammatory cascade characteristic of the disease. Psoriasin, along with other AMPs, can act as an "alarmin," a signal that alerts and activates other immune cells, thereby exacerbating inflammation.CircuLex S100A7/Psoriasin ELISA Kit This dual role—protective antimicrobial agent and contributor to inflammatory disease—underscores the complexity of psoriasin's functionThe antimicrobial peptides psoriasin (S100A7) and ....
Psoriasin exerts its antimicrobial effects through several mechanisms. One primary mechanism involves its ability to disrupt bacterial cell membranesIL-1β is a potent player in cutaneous inflammation and central for the development of a Th17 micro-milieu in autoinflammatory diseases includingpsoriasis. Its .... Like many antimicrobial peptides, psoriasin can interact with the lipid bilayers of bacterial cell membranes, leading to pore formation and cell lysis. This direct killing of bacteria is crucial for preventing infections. Furthermore, psoriasin has been shown to enhance the expression of other antimicrobial peptides, such as human neutrophil peptides (HNPs), creating a synergistic effect that strengthens the antimicrobial defense. Its ability to target specific bacteria, such as *E. coli*, suggests a degree of specificity in its action, though it contributes to a broader defense against various microbesS100A7/Psoriasin antibody (13061-1-AP).
While its antimicrobial properties are well-established, psoriasin is also recognized for its multifaceted roles in cellular regulation.Psoriasin(S100A7) is a principalantimicrobial peptideof the human tongue · Biology, Medicine. Mucosal Immunology · 2008. It has been implicated in processes such as keratinocyte differentiation, wound healing, and modulating the inflammatory responseThe antimicrobial peptide psoriasin (S100A7) mediates.... Research indicates that psoriasin can influence the extracellular matrix, potentially affecting tissue remodeling and repair.作者：S Morizane·2012·被引用次数：312—One characteristic abnormality of lesional skin inpsoriasisis the excessive production ofantimicrobial peptidesand proteins (AMPs). AMPs typically are small ... Its involvement in signaling pathways suggests it acts not only as a direct effector of immunity but also as a regulator of cellular behavior and communication within the immune system and surrounding tissues.
The understanding of psoriasin's role in both host defense and disease pathogenesis opens avenues for therapeutic strategies. For conditions like psoriasis, targeting the overproduction or activity of psoriasin and other AMPs could offer new treatment options. Conversely, leveraging psoriasin's antimicrobial properties might lead to the development of novel antibacterial agents, particularly in an era of increasing antibiotic resistance. Research continues to explore the precise mechanisms by which psoriasin interacts with pathogens and host cells, aiming to harness its beneficial aspects while mitigating its contribution to inflammatory conditions2025年8月6日—S100A7, anantimicrobial peptide, is also considered an inflammation-related protein [34,35], which was first found in patients withpsoriasis....
