The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Butyrate-producing Clostridium spp. play fundamental roles in maintaining gut microbiota homeostasis by producing short-chain fatty acids. However, exploration of the strain resources and their probiotic effects remains limited. In previous work, a n…
Vitamin D receptor [VDR] expression promotes LL37 expression, possibly contributing to host defense. The hypothesis was that an increase in 25 hydroxyvitamin D [25vitD] could lead to enhanced VDR expression and increased LL-37 production, thereby con…
BACKGROUND: The role of vitamin D in Coronavirus Disease 2019 (COVID-19) outcomes remains debated, but emerging evidence suggests it may enhance recovery by strengthening immune responses. Vitamin D upregulates LL-37, an antimicrobial peptide with br…
is among the life-threatening fungal species and the primary contributor to hospital-acquired systemic infections, accounting for nearly 70% of all fungal infections worldwide. The current treatment primarily relies on azoles, pyrimidine analogs, pol…
With antibiotic resistance being a major global concern, there is a huge need of new treatment options to fight bacterial infections. In this study, we highlight the antibacterial and host-protective roles of a novel synthetic antimicrobial peptide i…
The oral epithelium is essential for maintaining oral health and plays a key role in the onset and progression of periodontitis. It serves as both a mechanical and immunological barrier and possesses antimicrobial activity. Vitamin D, a hormone with…
species are often the cause of implant-related infections, posing a significant clinical challenge in orthopedics. Antimicrobial peptides (AMPs) like LL-37-derived FK-16 and GF-17 offer promising alternatives to conventional antibiotics; however, the…
(1) Background: In recent years, there has been a growing interest in understanding the innate immunity of the mouth, particularly the mechanisms through which vitamin D influences oral health. Researchers have increasingly focused on the association…
Bergeyella cardium causes infections in human organs. However, the mechanism of the virulence of B. cardium is unclear. Peptidases are important virulence factors in bacterial pathogens. Here, we identified three KP-43 subfamily peptidases, SpBcA, Sp…
Atherosclerosis (AS) is a prevalent clinical vascular condition and serves as a pivotal pathological foundation for cardiovascular diseases. Understanding the pathogenesis of AS has significant clinical and societal implications, aiding in the develo…
: Periodontitis is a multifactorial inflammatory disease influenced by immune and genetic factors. Certain genetic and immunological disorders, such as Down syndrome (DS), Leukocyte Adhesion Deficiency type I (LAD-I), and Papillon-Lefèvre syndrome (P…
INTRODUCTION: The constantly growing resistance of bacteria causing bloodstream infections and the lack of alternative antibiotics generate the need to develop new therapeutic strategies. In this study, the antibacterial properties of synthetic choli…
P2X receptors are a family of ATP-gated ion channels widely distributed in various tissues, especially in neuronal cells and hematopoietic cells. ATP activates P2X receptors, causing the opening of an ionic channel with preferential permeability to t…
The bacterial oral environment poses a significant challenge to the long-term stability of dental implants due to vulnerability of peri-implant soft tissues to pathogenic infiltration. Therefore, the rapid formation of a dense soft tissue barrier in…
Chronic spontaneous urticaria (CSU) is a significant clinical condition characterized by an undetermined etiology, with some of its manifestations being attributed to immunological factors. The antibacterial properties of the cathelicidin leucine-leu…
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…
Plasmids are major vehicles for the spread of antibiotic resistance genes. Some plasmids additionally carry virulence genes that enhance host pathogenicity. The convergence of resistance and virulence genes on the same plasmid poses significant risk,…
BACKGROUND: 1,25(OH)Dsupplementation alone does not provide sufficient benefit to hepatocellular carcinoma (HCC) patients in clinical trials. Tumor-associated macrophages (TAMs)-mediated immunosuppression is regarded as a major hurdle for the effecti…
Amyloidogenic and antimicrobial peptides (AMPs) share structural and functional similarities, suggesting that AMPs may have evolved from aggregation-prone amyloidogenic precursors through selective incorporation of cationic residues. The core segment…
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…
