The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
PURPOSE: Respiratory tract infections (RTIs) are a major cause of illness worldwide and the most common cause of hospitalization for pneumonia and bronchiolitis. These two diseases are the leading causes of morbidity and mortality among children unde…
Acinetobacter baumannii is one of the most challenging pathogens, on account of its predisposition to develop resistance leading to severe, difficult-to-treat infections. As these bacteria are more usually isolated from nosocomial infections, the new…
Immunization of patients with autologous,matured dendritic cell (DC) preparations, in order to prime antitumor T-cell responses, is the focus of intense research. Despite progress and approval of clinical approaches, significant enhancement of these…
Over the past three decades, a considerable body of evidence has highlighted T cells as pivotal culprits in the pathogenesis of psoriasis. This includes the association of psoriasis with certain MHC (HLA) alleles, oligoclonal expansion of T cells in…
The genetic repertoire underlying teleost immunity has been shown to be highly variable. A rare example is Atlantic cod and its relatives Gadiformes that lacks a hallmark of vertebrate immunity: Major Histocompatibility Complex class II. No immunolog…
Melioidosis is a severe disease caused by. The biofilm ofacquires resistance to several antibiotics and may be related to relapse in melioidosis patients. Here, the killing activity of antimicrobial peptides (LL-37, LL-31) and the D-enantiomers (D-LL…
Cathelicidins are effector molecules of vertebrate immunity that play vital roles against microbial invasion. They are widely identified in mammals, but few have been reported in Crocodilians, which are considered to be species with a powerful immune…
BACKGROUND Recent studies have proved that autophagy dysfunction in proinflammatory cells is involved in tissue damage and an excessive inflammatory response in sepsis. In the present study, we identified that the human antimicrobial peptide LL-37 fa…
Aroylated phenylenediamines (APDs) are novel inducers of innate immunity enhancing cathelicidin gene expression in human bronchial epithelial cell lines. Here we present two newly developed APDs and aimed at defining the response and signaling pathwa…
The emergence of carbapenem-resistantandraises fears of untreatable infections and poses the greatest health threats. Antimicrobial peptides (AMPs) are regarded as the most ideal solution to this menace. In this study, a set of peptides was designed…
PURPOSE: is the most common persistent pathogen in humans, so development of new formulations to combat pathogen invasion is quite necessary. METHODS: In the current study, for the first time, the synergistic activity of recombinant lysostaphin and L…
Venezuelan equine encephalitis virus (VEEV), a new world alphavirus belonging to the Togaviridae family, causes periodic disease outbreaks in humans and equines with high associated mortality and morbidity. VEEV is highly infectious via the aerosol r…
Temporins are anti-microbial peptides synthesized in the skin of frogs of thefamily. The few studies to date that have examined their anti-viral properties have shown that they have potential as anti-viral therapies. In this work, we evaluated the an…
BACKGROUND: Mycobacterium tuberculosis can grow in hostile intracellular environment of macrophages by actively evading macrophage-associated antibacterial activities. The stress response factor contributes this process by releasing inflammatory cyto…
BACKGROUND: Exacerbations of chronic obstructive pulmonary disease (COPD) are debilitating events and spur disease progression. Infectious causes are frequent; however, it is unknown to what extent exacerbations are caused by larger shifts in the air…
The innate immune element, cathelicidin antimicrobial peptide (CAMP), is vital in the formation of the antimicrobial barrier in skin. CAMP production is increased during epidermal differentiation and enriched in the stratum corneum. We recently ident…
Mouse cathelin-related antimicrobial peptide (CRAMP) and its homologue human cathelicidin (LL-37) play active roles in innate immune responses, angiogenesis, and wound healing. In addition, LL-37/CRAMP fends off microbes and protects against infectio…
(PA) is the leading cause of corneal blindness worldwide. A constant increase in multi-drug resistant PA strains have heightened the challenge of effectively managing corneal infections with conventional antibiotics. Antimicrobial peptides are promis…
The gut microbiota can play a role in pancreatitis and, likely, in the development of type 1 diabetes (T1D). Anti-microbial peptides and secretory proteins are important mediators of the innate immune response against bacteria but their expression in…
is the leading cause of bacterial keratitis in the developing world with a growing trend of acquiring resistance against various antibiotics. In the current study, we determined the expression of different antimicrobial peptides (AMPs) in response to…
