The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Lacticaseibacillus paracasei cell wall presents two capsular polysaccharides, CPS-1 and CPS-2, and a teichoic acid. CPS-1 is novel and it presents a branched heptasaccharide repeating unit, with the sequence →6)-α-d-Gal-(1→3)-β-l-Rha-(1→4)-β-d-Glc-(1…
Ferroptosis is an important cause of cardiomyocyte loss and cardiac dysfunction. Cathelicidin-related antimicrobial peptide (CRAMP) is an endogenous polypeptide that regulates oxidative stress in the body and is involved in ferroptosis. However, its…
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…
Obesity is a risk factor of developing type 2 diabetes (T2D) and metabolic complications, through systemic inflammation and insulin resistance. It has also been associated with increased bone marrow adipocytes along with increased bone fragility and…
Infections with the protozoancause abortion in cattle, likely due to the parasite's replication and excessive inflammation in the placenta. Cathelicidins are host defense peptides known for their antimicrobial and immunomodulatory functions, but thei…
BACKGROUND: Idiopathic granulomatous mastitis (IGM) is a chronic inflammatory disorder characterised by the formation of non-caseating granulomas in breast tissue, primarily affecting young women of childbearing age. The aetiology of IGM remains uncl…
: Excessive body fatness is the basis of many diseases, especially civilization-related ones. The aim of this study is to analyze the body composition and serum levels of selected antimicrobial peptides (AMPs) in patients with basal cell carcinoma (B…
: Cutaneous squamous cell carcinoma (cSCC) is a common cutaneous malignancy with diverse etiologies, including actinic keratosis, burns, and hidradenitis suppurativa (HS).: We reviewed 237 cases diagnosed as cSCC in our department between 2013 and 20…
Colonic goblet cells play a crucial role in mucosal defense by secreting Muc2 mucin and other proteins that entrap and expel enteropathogens. However, the role of innate effectors in the gut like cathelicidin peptides in regulating the mucus barrier…
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis (Mtb) and is a growing public health problem worldwide. Within the innate immune response, we highlight the secretion of the antimicrobial peptide LL-37, which is crucial for…
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…
INTRODUCTION: The emergence of antibiotic-resistant pathogens is a significant global health concern that necessitates the development of new antimicrobial drugs. Due to its broad-spectrum action against bacteria, fungi, and viruses, human cathelicid…
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…
Lytic transglycosylase A in Neisseria gonorrhoeae cleaves the β-1,4-glycosidic bond between peptidoglycan (PG) monomers to liberate 1,6-anhydro-PG fragments that are either recycled or released as cytotoxic fragments. To gain further insight into the…
BACKGROUND: Numerous studies have shown the presence of multiple defence factors in placental tissue, although their role is partially understood; therefore, the aim of this study was to evaluate the expression of nuclear factor-kappa B (NF-κB); huma…
Psoriasis, a chronic inflammatory skin disorder, is characterized by a complex interplay among immune cells. Although the specific mechanisms of platelet involvement in psoriasis are not fully elucidated, platelet activation is considered a major pat…
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…
INTRODUCTION: Oral diseases such as caries and periodontitis are complex, multifactorial diseases and remain the most prevalent worldwide. Both diseases are associated with vitamin D deficiency (VDD) and its pathophysiological process. The prevalence…
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…
BACKGROUND: The escalating global threat of antimicrobial resistance (AMR) necessitates the development of novel antimicrobial agents, innovative strategies, and representative infection models to combat AMR bacterial infections. Host defence peptide…
