The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
A recurrent case of left-sided endocarditis caused by high-level aminoglycoside-resistant Enterococcus faecalis was successfully treated with ceftaroline and daptomycin. This combination demonstrated excellent synergy in vitro. Mechanistically, cefta…
The purpose of the study was to elucidate whether responses to vibriosis vaccination and gene expressions in parts of the innate immune system were different in families of Atlantic cod (Gadus morhua). The fish were progenies of families with differe…
The α-chemokine stromal derived factor 1 (SDF-1), which binds to the CXCR4 and CXCR7 receptors, directs migration and homing of CXCR4+ hematopoietic stem/progenitor cells (HSPCs) to bone marrow (BM) and plays a crucial role in retention of these cell…
The oomycete Saprolegnia parasitica causes significant losses in the aquaculture industry, mainly affecting salmon, trout and catfish. Since the ban of malachite green, effective control measures are currently not available prompting a re-evaluation…
Antimicrobial peptides, molecules produced in many different organisms, have high biocidal activity against several microorganisms. However, several questions about these molecules remain unclear. Therefore, this report details a systematic survey of…
Apart from direct bacterial killing, antimicrobial host defence peptides (HDPs) exert various other biological activities that also include modulation of immune responses to infection. The bovine cathelicidin BMAP-28 has been extensively studied with…
Hematopoietic stem progenitor cells (HSPCs) respond robustly to α-chemokine stromal-derived factor-1 (SDF-1) gradients, and blockage of CXCR4, a seven-transmembrane-spanning G(αI)-protein-coupled SDF-1 receptor, mobilizes HSPCs into peripheral blood.…
BACKGROUND: Acne inversa is a chronic, suppurative relapsing inflammatory skin disease that primarily affects the axillae, perineum and inframammary regions. Evidence suggests that the innate immune system is involved in the pathogenesis of acne inve…
Neutrophils play an important role in periodontitis by producing nitric oxide (NO) and antimicrobial peptides, molecules with microbicidal activity via oxygen-dependent and -independent mechanisms, respectively. It is unknown whether variation in the…
Congenital unilateral linear porokeratosis (CULP) is a rare disorder of keratinization that shares clinical and molecular similarities with psoriasis. It also has an increased risk for malignant transformation to cutaneous squamous cell carcinoma (SC…
Antimicrobial peptides of the cathelicidin family are found in many mammalian species, and are focused on various effects other than antimicrobial action. In this study, we evaluated the anti-proliferative effect of an analogue peptide, FF/CAP18, der…
Leukocyte apheresis primarily used for treatment of inflammatory diseases such as inflammatory bowel disease (IBD). Beside an effect of the apheresis column, the plastic lines in the apheresis system might also have an effect due to interaction betwe…
BACKGROUND: The effects of serum vitamin D status on atopy, steroid requirement, and functional responsiveness to corticosteroids in children versus adults with asthma have not been studied systematically. OBJECTIVE: We sought to explore the age-spec…
BACKGROUND: Patients, especially young children, with atopic dermatitis are at an increased risk of developing eczema vaccinatum, a severe reaction to the smallpox vaccine, either through direct vaccination or indirect contact with a person recently…
Some antimicrobial peptides have emerged as potential anticancer agents. In contrast to chemotherapeutics, they act primarily by physical disruption of the cancer cell membrane. Selective targeting of these cationic peptides still remains elusive. We…
BACKGROUND: Vitamin D, which exerts its effect through vitamin D receptor (VDR), and LL-37, a vitamin D-dependent antimicrobial peptide, are involved in many infectious diseases. AIM: The objective of this study was to evaluate whether vitamin D stat…
Enterohemorrhagic Escherichia coli (EHEC) and enteropathogenic E. coli (EPEC) are food-borne pathogens that cause serious diarrheal diseases. To colonize the human intestine, these pathogens must overcome innate immune defenses such as antimicrobial…
As members of the indigenous human microbiota found on several mucosal tissues, Methanobrevibacter smithii and Methanosphaera stadtmanae are exposed to the effects of antimicrobial peptides (AMPs) secreted by these epithelia. Although antimicrobial a…
Host defense peptides (HDPs) are an evolutionarily conserved component of the innate immune response found in all living species. They possess antimicrobial activities against a broad range of organisms including bacteria, fungi, eukaryotic parasites…
PURPOSE: Superficial dermatophytosis is quite commonly seen in patients with adult T-cell leukemia/lymphoma (ATLL), as approximately 50% of the patients develop cutaneous mycotic infections. Because superficially infected fungi in the stratum corneum…
