A bovine myeloid antimicrobial peptide antimicrobial peptide (BMAP-28) is a member of the cathelicidin family and acts as a component of innate immunity. There are few reports of susceptibility difference of methicillin-resistant Staphylococcus aureu…
Infections with the parasitic flagellate Ichthyobodo necator (Henneguy, 1883) cause severe skin and gill disease in rainbow trout Oncorhynchus mykiss (Walbaum, 1792) juveniles. The epidermal disturbances including hyperplasia and mucous cell exhausti…
Polymorphisms in the CAMP gene (cathelicidin) have not been tested in tuberculosis susceptibility. We tested polymorphisms rs9844812 (HIF-1α::ARNT binding site) and rs56122065 (CAMP) plus rs1800972 (DEFB1). SNP rs1800972 was associated with extrapulm…
Antimicrobial peptides (AP) are important components of the innate immune system, yet little is known about their expression and function in the brain. Our previous work revealed upregulated gene expression of cathelicidin-related AP (CRAMP) followin…
The cathelicidin family is one of the several families of antimicrobial peptides (AMPs). A bovine myeloid antimicrobial peptide (BMAP-28) belongs to this family. Recently, the emergence of drug-resistant bacteria such as methicillin-resistant Staphyl…
SCOPE: The cathelicidin antimicrobial peptide (CAMP) gene is induced by 1α,25-dihydroxyvitamin D3 (1α,25(OH)2 D3), lithocholic acid, curcumin, nicotinamide, and butyrate. Discovering additional small molecules that regulate its expression will identi…
Current therapies for autoimmune chronic inflammatory diseases e.g. rheumatoid arthritis (RA) include inhibitors of inflammatory cytokines. However, these therapies can result in increased risk of infections. There is a need to explore alternate stra…
Human cathelicidin (hCAP 18) is one of the main immunomodulators in the local immune response to Mycobacterium tuberculosis. There has been no information regarding the role of hCAP 18+ in the in vivo production of cytokine in childhood pulmonary tub…
Bacterial infections are becoming increasingly difficult to treat due to the increasing number of multidrug-resistant strains. Cathelicidin-BF (BF-30) is a cathelicidin-like antimicrobial peptide and exhibits broad antimicrobial activity against bact…
LL-37 is a multifunctional component of innate immunity, with a membrane-directed antimicrobial activity and receptor-mediated pleiotropic effects on host cells. Sequence variations in its primate orthologues suggest that two types of functional feat…
Small ubiquitin-related modifier (SUMO) technology has been widely used in Escherichia coli expression systems to produce antimicrobial peptides. However, E. coli is a pathogenic bacterium that produces endotoxins and can secrete proteins into the pe…
The presence and localization of cathelicidin anti-microbial peptides in the lizard, Anolis carolinensis, were investigated by immunocytochemistry. The study showed that immunoreactivity for cathelicidins 1 and 2 was only present in large granules of…
Bacterial resistance against common antibiotics is an increasing health problem. New pharmaceuticals for the treatment of infections caused by resistant pathogens are needed. Small proline-rich antimicrobial peptides (PrAMPs) from insects are known t…
Bac7(1-35) is an active fragment of the bovine cathelicidin antimicrobial peptide Bac7, which selectively inactivates Gram-negative bacteria both in vitro and in mice infected with Salmonella typhimurium. It has a non-lytic mechanism of action, is ra…
Antimicrobial peptides (AMPs) hold great promise as potential therapeutic approach for curing of infectious diseases. Prokaryotic protein expression renders high scalability with an effective purification of several heterogeneous proteins. However, i…
BACKGROUND: Vitamin D receptor (VDR) is a member of the nuclear receptor family of transcription factors that play a critical role in innate immunity. This study examined the role of VDR in gastric innate immune defence against the gastric pathogen H…
The antibacterial protein hepcidin regulates the absorption, tissue distribution, and extracellular concentration of iron by suppressing ferroportin-mediated export of cellular iron. In CKD, elevated hepcidin and vitamin D deficiency are associated w…
BACKGROUND: Antimicrobial peptides (AMPs) are small proteins present in most living species and they are involved in the defence against pathogenic organisms. β-Defensins and cathelicidin are the most frequently studied AMPs in both people and dogs.…
Antimicrobial peptides are important for a healthy host-microbe homeostasis. In infections characterized by low levels of the human cathelicidin, LL-37, induction of its expression increases clearance of pathogens. Our aim was to discover signaling p…
Blood-feeding parasites have developed biochemical mechanisms to control heme intake and detoxification. Here we show that a major antigen secreted by Fasciola hepatica, previously reported as MF6p, of unknown function (gb|CCA61804.1), and as FhHDM-1…
