The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Alcohol consumption and obesity are known risk factors of steatohepatitis. Here, we report that the deficiency of CRAMP (cathelicidin-related antimicrobial peptide-gene name:) is protective against a high-fat diet (HFD) plus acute alcohol (HFDE)-indu…
LL-37, a well-known antimicrobial human peptide, is a cationic peptide that provides an important antimicrobial defense mechanism in damaged skin. Accumulating evidence indicates that LL-37 also displays an anticancer effect in colon cancer, gastric…
OBJECTIVE: To investigate the diagnostic value of the T cell spot (T-SPOT.TB) test, oxidation-related factors (ORF), and antimicrobial peptide LL-37 in patients with pulmonary tuberculosis (PTB) with type 2 diabetes. METHODS: A total of 560 patients…
BACKGROUND: In periodontal connective tissue cells, the vitamin D pathway has been elucidated, and vitamin Din the main storage form, 25-hydroxy vitamin D(25[OH]D), and the functional form, 1,25-dihydroxy vitamin D(1,25[OH]D), have been found to indu…
Preservation of intestinal stem cells (ISCs) plays a critical role in initiating epithelial regeneration after intestinal injury. Cathelicidin peptides have been shown to participate in regulating intestinal damage repair. However, it is not known ho…
Active form of vitamin D (VitD) enhances human innate immunity against() infection. Our previous studies showed that MIR337-3p was highly expressed in lymphocytes of tuberculosis (TB) patients. Here, we identified the mechanism of MIR337-3p in the re…
Infections are a major complication of obesity, but the mechanisms responsible for impaired defense against microbes are not well understood. Here, we found that adipocyte progenitors were lost from the dermis during diet-induced obesity (DIO) in hum…
Based on the cathelicidin family antimicrobial peptide Hc-CATH derived from sea snake, the Hc-16 and Hc-15 of 16 and 15 amino acid residues, were designed. By using CCK8, minimal inhibitory concentration, ELISA and bio-layer interferometry assays, th…
SARS-CoV-2 coronavirus infection induces heterogeneous symptoms, ranging from asymptomatic to lethal forms. Severe forms usually occur in the elderly and/or individuals with comorbidities. Children generally remain asymptomatic to primary infection,…
Human cathelicidin antimicrobial peptide LL-37 (LL-37) is an antimicrobial peptide derived from its precursor protein hCAP18, which is an only cathelicidin in human. LL-37 not only serves as a mediator of innate immune defense against invading microo…
BACKGROUND: We aimed to establish an acute treatment protocol to increase serum vitamin D, evaluate the effectiveness of vitamin D3 supplementation, and reveal the potential mechanisms in COVID-19. METHODS: We retrospectively analyzed the data of 867…
Chemerin-derived peptide Val-Pro(p4) restricts the growth of a variety of skin-associated bacteria, including methicillin-resistant(MRSA). To better understand the antimicrobial potential of chemerin peptide, we compared p4 activity against MRSAto ca…
We previously reported that conjugates of antimicrobial peptide fragment analogues and poly (lactic-co-glycolic) acid (PLGA) enhance antimicrobial activity and that the conjugated micelle structure is an effective tool for antimicrobial drug delivery…
HYPOTHESIS: pH-responsive nanocarriers have the potential to provide targeted delivery of antimicrobial peptides (AMPs) to sites of bacterial infection with typically abnormal pH levels in the body. However, the local pH of the infected sites varies…
Angiogenesis, the growth of new blood vessels from preexisting vessels, is associated with inflammation in various pathological conditions. Well-known angiogenetic factors include vascular endothelial growth factor (VEGF), angiopoietins, platelet-der…
The increasing numbers of infections caused by multidrug-resistant (MDR) pathogens highlight the urgent need for new alternatives to conventional antibiotics. Antimicrobial peptides have the potential to be promising alternatives to antibiotics becau…
Antimicrobial peptides (AMPs) are one of the primary mechanisms used by the skin in the early stages of immune defense. AMPs have a broad antibacterial activity and also show antifungal and antiviral attributes. Various studies have also shown that l…
Synthetic, cationic random nylon-3 polymers (β-peptides) show promise as inexpensive antimicrobial agents less susceptible to proteolysis than normal peptides. We have used superresolution, single-cell, time-lapse fluorescence microscopy to compare t…
One of defense mechanisms of the human immune system to counteract infection by the opportunistic fungal pathogenis the recruitment of neutrophils to the site of invasion, and the subsequent production of neutrophil extracellular traps (NETs) that ef…
(1) Background: The cathelicidin peptide LL-37 is a prominent molecule with many biological activities, including antimicrobial. Due to its importance, here, we describe the production of LL-37 tagged with SmbP, a relatively new carrier protein that…
