Inflammatory signaling through macrophages and the innate immune system are increasingly recognized as important contributors to multiple acute and chronic disease processes. Nitric oxide (NO) is a free radical that plays an important role in immune and inflammatory responses as an important intercellular messenger. In addition, NO has an important role in inflammatory responses in mucosal environments such as the ocular surface. Histatin peptides are well-established antimicrobial and wound healing agents. These peptides are important in multiple biological systems, playing roles in responses to the environment and immunomodulation.

  • A Novel Secretion and Online-Cleavage Strategy for Production of Cecropin a in Escherichia Coli
    www.nature.com/scientificreports OPEN A novel secretion and online- cleavage strategy for production of cecropin A in Escherichia coli Received: 14 March 2017 Meng Wang 1, Minhua Huang1, Junjie Zhang1, Yi Ma1, Shan Li1 & Jufang Wang1,2 Accepted: 23 June 2017 Antimicrobial peptides, promising antibiotic candidates, are attracting increasing research attention. Published: xx xx xxxx Current methods for production of antimicrobial peptides are chemical synthesis, intracellular fusion expression, or direct separation and purifcation from natural sources. However, all these methods are costly, operation-complicated and low efciency. Here, we report a new strategy for extracellular secretion and online-cleavage of antimicrobial peptides on the surface of Escherichia coli, which is cost-efective, simple and does not require complex procedures like cell disruption and protein purifcation. Analysis by transmission electron microscopy and semi-denaturing detergent agarose gel electrophoresis indicated that fusion proteins contain cecropin A peptides can successfully be secreted and form extracellular amyloid aggregates at the surface of Escherichia coli on the basis of E. coli curli secretion system and amyloid characteristics of sup35NM. These amyloid aggregates can be easily collected by simple centrifugation and high-purity cecropin A peptide with the same antimicrobial activity as commercial peptide by chemical synthesis was released by efcient self-cleavage of Mxe GyrA intein. Here, we established a novel expression strategy for the production of antimicrobial peptides, which dramatically reduces the cost and simplifes purifcation procedures and gives new insights into producing antimicrobial and other commercially-viable peptides. Because of their potent, fast, long-lasting activity against a broad range of microorganisms and lack of bacterial resistance, antimicrobial peptides (AMPs) have received increasing attention1.

  • Expression and Function of Host Defense Peptides at Inflammation
    International Journal of Molecular Sciences Review Expression and Function of Host Defense Peptides at Inflammation Sites Suhanya V.

The physicochemical properties and selective interaction of HDPs with various receptors define their immunomodulatory effects. However, it is quite challenging to understand their function because some HDPs play opposing pro-inflammatory and anti-inflammatory roles, depending on their expression level within the site of inflammation. While it is known that HDPs maintain constitutive host protection against invading microorganisms, the inducible nature of HDPs in various cells and tissues is an important aspect of the molecular events of inflammation. This review outlines the biological functions and emerging roles of HDPs in different inflammatory conditions. We further discuss the current data on the clinical relevance of impaired HDPs expression in inflammation and selected diseases. Keywords: host defense peptides; human antimicrobial peptides; defensins; cathelicidins; inflammation; anti-inflammatory; pro-inflammatory 1. Introduction The human body is in a constant state of conflict with the unseen microbial world that threatens to disrupt the host cell function and colonize the body surfaces.
