The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Helminths can manipulate their host's gut microbiota, with the expansion of the lactobacilli population being a common feature. This process profoundly influences host immunoregulation, yet the underlying mechanisms remain almost unknown. Using a tis…
Cathelicidins are a diverse family of antimicrobial peptides found across many vertebrate species, playing a pivotal role in the innate immune system. These peptides exhibit a variety of structural motifs, including α-helices, β-hairpins, and random…
Sepsis-induced acute lung injury (ALI) is a serious disease constituting a heavy burden on society due to high mortality and morbidity. Inflammation and oxidative stress constitute key pathological mechanisms in ALI caused by sepsis. LL-37 can improv…
INTRODUCTION: Cathelicidins are a family of antimicrobial peptides well-known for their antimicrobial and immunomodulatory functions in eutherian mammals such as humans. However, cathelicidins in marsupials, the other major lineage of mammals, have r…
Fibroblasts that reside in the gut mucosa are among the key regulators of innate immune cells, but their role in the regulation of the defense functions of macrophages remains unknown. MyD88 is suggested to shape fibroblast responses in the intestina…
The lysosomal cysteine protease cathepsin S supports host defence by promoting the maturation of MHC class-II proteins. In contrast, increased cathepsin S activity mediates tissue destructive immune responses in autoimmune and inflammatory diseases.…
Isothermal titration calorimetry (ITC), circular dichroism (CD) spectroscopy, and molecular dynamics simulations were applied to describe interactions between lipopeptides and decavanadate ions ([VO]). The selected lipopeptides are conjugates of the…
Klebsiella pneumoniae is becoming increasingly difficult to treat as multidrug-resistant (MDR) strains become more prevalent. The formation of biofilm heightens this threat by embedding bacterial cells in a polysaccharide-rich matrix that limits anti…
Infections after psychological stress are a major health care problem. Single-cell transcriptomics and lipidomic profiling in a mouse model of stress show that dermal fibroblasts undergoing adipogenesis have defective responses toskin infection. Adre…
Antimicrobial peptides (AMPs), such as cathelicidins, show dual functionality by directly combating pathogens and indirectly eliminating them through stimulation of the immune system, generating interest in their therapeutic potential. Pigs have a la…
Tillage operation aims to create a favorable environment for seed germination of agricultural crop production practices. Physio-mechanical properties of soil directly affecting soil behaviors and determinants in initial conditions affecting soil fail…
Burn trauma triggers dysregulated systemic inflammation, leading to multiorgan dysfunction. Respiratory failure often follows burn injury, resulting in morbidity and mortality, in part, because of excessive and prolonged release of local and systemic…
BACKGROUND: Ruminants possess a rich repository of natural antimicrobial peptides(AMPs) within their bodies, surpassing those found in humans and mice. These peptides, including Defensin, Cathelicidin, and Lysozyme, are integral to the body's innate…
INTRODUCTION: Monoosteophils, derived from LL-37-treated monocytes, are a novel type of calcifying/bone forming cells. We have shown that monoosteophils can form bone-like nodulesand accelerate bone repair in a drilled femur defect model. Here, we ex…
AIMS: This study aims to develop novel antibacterial agents by targeting SufA protease, a key virulence factor in Finegoldia magna, using 1-aminoalkylphosphonate (1-AAP) diaryl esters as inhibitors. MATERIALS & METHODS: Structural optimization of a r…
Excessive glucose absorption is a major contributing factor of metabolic disorders that necessitates effective therapeutic strategies. This study investigates the potential of fermentedextract (FACE) in regulating glucose transport and immune respons…
OBJECTIVE: To assess the feasibility of gene expression profiling of platelets in dogs with sepsis. METHODS: This was a prospective observational feasibility study conducted at a university veterinary teaching hospital. All study dogs had CBCs and se…
Antimicrobial peptides (AMPs) are natural molecules of great interest in the fight against bacteria and in addressing antibiotic resistance. Their use as antimicrobial drugs is still limited due to their cytotoxicity and poor resistance to proteolysi…
BACKGROUND: Diosgenin, a well-known steroid sapogenin, has demonstrated anti-inflammatory effects; however, its therapeutic potential for sepsis remains unclear. Intestinal barrier dysfunction is a critical contributor to lethal sepsis, a systemic in…
The aberrant aggregation of the human islet amyloid polypeptide (hIAPP) is a hallmark of type II diabetes. LL37, the only cathelicidin host-defense peptide in humans, plays essential roles in antimicrobial and immunomodulatory activities. Mounting ev…
