The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
OBJECTIVE: This study aimed to evaluate the efficacy of narrow-band ultraviolet B (NB-UVB) phototherapy, methotrexate, and combined NB-UVB phototherapy with methotrexate in the treatment of psoriasis vulgaris and to assess their effects on serum cath…
OBJECTIVES: Sepsis is a lethal clinical condition with dysregulated cluster of differentiation (CD) 4T cells that leads to inflammation and multiorgan injury. Low vitamin D levels are commonly seen in patients with sepsis. Obesity is a state with oxi…
Leprosy is an infectious disease influenced by genetic, immunological, and environmental factors. Reduced gene expressions may be associated with the immunological response pattern and leprosy susceptibility. We investigated the direct and indirect e…
Porphyromonas gingivalis is a keystone oral pathogen that successfully manipulates the human innate immune defenses, resulting in a chronic proinflammatory state of periodontal tissues and beyond. Here, we demonstrate that secreted outer membrane ves…
Legionella micdadei is responsible for community- or nosocomial-acquired pneumonia as well as the influenza-like illness Pontiac fever. The aim of this study was to investigate the ability of L. micdadei to utilize extracellular choline for phosphati…
The human cathelicidin hCAP-18 (pro-LL-37) is the pro-protein of the antimicrobial peptide LL-37. hCAP-18 can be produced by many different cell types; bone marrow neutrophil precursors are the main source of hCAP-18 in the circulation. Neutrophil co…
Tuberculosis (TB) presents a serious health problem with approximately a quarter of the world's population infected with() in an asymptomatic latent state of which 5-10% develops active TB at some point in their lives. The antimicrobial protein cathe…
This study evaluated the in vitro activity of antimicrobial peptides pexiganan (MSI-78), h-Lf1-11, LL-37, cecropin B, magainin-2, and fengycin B against the veterinary mastitis agent Prototheca bovis. The results showed that pexiganan, h-Lf1-11, LL-3…
To study the molecular interplay between TLRs and complement representing ancient danger-sensing mechanisms, we examined the regulation of the C3a/anaphylatoxin C3a receptor (C3aR) axis in normal human epidermal keratinocytes (NHEKs) by treatment wit…
BACKGROUND: Protecting the intestinal mucosa from being destroyed helps reduce the inflammation caused by acute pancreatitis (AP). In this study, whether okra pectin (OP) could attenuate the inflammation of AP through protecting the intestinal barrie…
Palmoplantar pustulosis (PPP) is a chronic dermatitis characterized by sterile intra-epidermal pustules associated with erythema and scales on the palms and soles. Tumor necrosis factor (TNF)-α/interleukin (IL)-23/IL-17 inflammatory pathway may be in…
Timely and objective diagnosis and classification of mastitis is crucial to ensure adequate management and therapeutic decisions. Analyzing specific biomarkers in milk could be advantageous compared with subjective or semiquantitative criteria, such…
Leptospires are aerobic, Gram-negative spirochetes with a high invasive capacity. Pathogenic leptospires secrete proteases that inactivate a variety of host's proteins including molecules of the extracellular matrix and of the human complement system…
BACKGROUND: Antimicrobial peptides are components of innate immune response that have a key role on susceptibility and resistance of the oral cavity to diseases. This study aimed to investigate the influence of smoking on cathelicidin LL-37 and human…
Characterization of biomolecular dynamics at cellular membranes lags far behind that in solutions because of challenges to measure transmembrane trafficking with subnanometer precision. Herein, by introducing nonfluorescent quenchers into extracellul…
Incidence of drug resistance in clinical isolates of methicillin-resistant(MRSA) is attributed to its diverse repertoire of virulence factors. Of these virulence determinants, Panton-Valentine Leukocidin (PVL) has been experimentally validated as a p…
Type 1 diabetes has an increasingly greater incidence and prevalence with no cure available. Vitamin D supplementation is well documented to reduce the risk of developing type 1 diabetes. Being involved in the modulation of cathelicidin expression, t…
Several epidemiological studies have identified the cigarette smoke as a risk factor for the infection and development of tuberculosis. Nicotine is considered the main immunomodulatory molecule of the cigarette. In the present study, we evaluated the…
The remarkable ability of Pseudomonas aeruginosa to form biofilms renders antibiotic treatments inefficient and therefore causing a wide variety of chronic infections. The quorum sensing (QS) system in P. aeruginosa plays a role in the regulation of…
species can form biofilms on tissues and medical devices, making them less susceptible to antifungal agents.Antifungal combination may be an effective strategy to fight againstbiofilm.In this study, we investigated theactivity of fluconazole, caspofu…
