The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
BACKGROUND: Kawasaki disease (KD) is a type of vasculitis with an unidentified etiology. Cathelicidin (LL-37) may be involved in the development of the KD process; therefore, further research to investigate the molecular mechanism of LL-37 involvemen…
Neutrophils are essential for host defense against(). The neuro-repellent, SLIT2, potently inhibits neutrophil chemotaxis, and might, therefore, be expected to impair antibacterial responses. We report here that, unexpectedly, neutrophils exposed to…
The only human cathelicidin, LL-37, is a host defense antimicrobial peptide with antimicrobial activities against protozoans, fungi, Gram(+) and Gram(-) bacteria, and enveloped viruses. It has been shown in experiments in vitro that LL-37 is able to…
is a leading cause of antibiotic-associated diarrheal disease.colonization, growth, and toxin production in the intestine is strongly associated with its ability to use amino acids to generate energy, but little is known about the impact of specific…
Microglia-mediated chronic neuroinflammation has been associated with cognitive decline induced by rotenone, a well-known neurotoxic pesticide used in agriculture. However, the mechanisms remain unclear. This work aimed to elucidate the role of compl…
Salivary innate defenses encompass mechanical cleaning, calcium phosphate salts and fluoride ion reduction of enamel dissolution rate, buffering capacity and neutralizing capacity, and antibacterial properties employing antimicrobial substances like…
Identification of novel antibiotics is of top importance because of the threat of antibiotic-resistant pathogens. Antimicrobial screening in Mueller-Hinton broth is frequently the first step in antimicrobial discovery. Although widely utilized, this…
Type 1 diabetes (T1D) is an incurable condition with an increasing incidence worldwide, in which the hallmark is the autoimmune destruction of pancreatic insulin-producing β cells. Cathelicidin-based peptides have been shown to improve β cell functio…
is a major human fungal pathogen, and antimicrobial peptides are key components of innate immunity. Studying the interplay betweenand human antimicrobial peptides would enhance a better understanding of pathogen-host interactions. Moreover, potential…
AIM: To analyze a series of antimicrobial peptides (AMPs) in corneal tissue from individuals with fungal keratitis (FK) during the active phase of the fungus infection and after healing. METHODS: Patients undergone lamellar keratoplasty for the treat…
BMAP-18, derived from the N-terminal region of bovine myeloid antimicrobial peptide BMAP-27, demonstrates potent antimicrobial activity without cytotoxicity. This study aimed to compare the antibacterial, antibiofilm, and anti-inflammatory properties…
Cationic antimicrobial peptides (CAMPs) are powerful molecules with antimicrobial, antibiofilm and endotoxin-scavenging activities. These properties make CAMPs very attractive drugs in the face of the rapid increase in multidrug-resistant (MDR) patho…
Goats are an excellent animal model for research on some physiological and pathophysiological processes in humans. The search for supplements that prevent homeostasis disorders and strengthen the immune system is necessary to reduce the risk of many…
BACKGROUND: Although there are studies on colostrum and milk proteomics of different species in the literature, there is no published report about different quality bovine colostrums' proteomics. OBJECTIVES: The aim of this study was to compare the p…
BACKGROUND: The immunomodulatory effects of Vitamin D expand to induce the synthesis of an antimicrobial peptide, cathelicidin. There is evidence showing altered levels of cathelicidin in tuberculosis (TB). It has been suggested that Vitamin D-mediat…
Hepatocellular carcinoma (HCC) is associated with high rates of metastasis and recurrence, and is one of the most common causes of cancer-associated death worldwide. This study examined the protein changes within circulating exosomes in patients with…
Glioblastoma (GBM) is an aggressive and lethal malignancy of the central nervous system with a median survival rate of 15 months. We investigated the combined anticancer effects of nerve growth factor (NGF), cathelicidin (LL-37), and protegrin-1 (PG-…

is a zoonotic Gram-positive bacterium that causes invasive infections such as sepsis and meningitis, threatening public health worldwide. For successful establishment of infection, the bacterium should subvert the innate effectors of immune defence,…
Anti-microbial peptides play a vital role in the defense mechanisms of various organisms performing functions that range from the elimination of microorganisms, through diverse mechanisms, to the modulation of the immune response, providing protectio…
