The liver fluke Opisthorchis viverrini causes chronic infections in humans and animals. This helminth is known to coexist with the bacterial microbiome in the host's bile duct, and their interaction potentially impacts the helminth's pathogenicity. W…
Candida glabrata (currently classified as Nakaseomyces glabratus) is an opportunistic yeast-like fungus that causes infections in humans, with limited treatment options due to resistance to antifungal drugs. In contrast to C. albicans, which produces…
Cathelicidin LL-37, an antimicrobial peptide (AMP) of the innate immune system, wards off bacterial infections. Recent research has identified plenty of biological functions of AMPs beyond their antimicrobial activity, including antioxidant, self-ren…
LL-37 and its variants with amphiphilic structure can modulate amyloid-β (Aβ) fibril formation, but the detailed mechanism behind it is still unclear. By using four different peptides (LL-37, LL-37, LL-37, LL-37), we found these peptides affect Aβ40…
Macrophages are professional phagocytes that play a major role in engulfing and eliminating invading pathogens. Some intracellular pathogens, such as Salmonella enterica serovar Typhimurium, exploit macrophages as niches for their replication, which…
INTRODUCTION: Vesicoureteral reflux (VUR) is a prevalent pediatric urological condition that increases children's risk of urinary tract infections (UTIs) and renal damage. Renal scarring linked to VUR can lead to long-term complications, including hy…
Diabetic wounds, due to severe vascular dysfunction, persistent inflammatory responses, and susceptibility to microbial infections, exhibit delayed healing and pose a significant challenge to human health. Diabetic wounds face delayed healing and sig…
Antimicrobial peptides, which function as the first line of host immune defense, have recently been identified as important immunomodulators of inflammation, and are involved as regulatory molecules in infections, including sepsis. Treatment of sepsi…
The increasing threat of bacterial drug resistance calls for effective solutions, and antimicrobial peptides (AMPs) hold great promise. However, the connection between their structure and function remains unclear. The study of the structure-function…
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…
The escalating threat of antibiotic resistance demands novel antimicrobial strategies. This study introduces PCR12mod6, a rationally designed peptide derived from the amphibiancathelicidin-HR, engineered for both antimicrobial and antioxidant functio…
The authors explored the genomic landscape of bat cathelicidins, critical proteins in the vertebrate innate immune system, across 41 bat species, which are notable for their high microbial tolerance. An array of bioinformatics tools, complemented by…
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…
INTRODUCTION: Research has been intensive on the possibility of using the ideal oral fluids in the prediction and diagnosis of periodontal disease. OBJECTIVES: This study aimed to detect the most accurate biomarkers that can be used to predict and di…
INTRODUCTION AND AIMS: LL-37, an antimicrobial peptide with dual pro-/anti-inflammatory roles, has been implicated in the pathogenesis of periodontitis, yet its specific action through its receptor Formyl peptide receptor 2 (FPR2) remains unclear. Th…
Cryptosporidiosis, caused by, poses significant health risks, particularly for children and immunocompromised individuals. Current treatments are ineffective in these vulnerable groups. This study explores the antiparasitic effects of peptoids agains…
Rosacea is a chronic inflammatory skin disorder linked to the antimicrobial peptide LL-37 and immune cells. STING, a key DNA-sensing adaptor, initiates innate immune responses, with excessive activation contributing to inflammation. This study invest…
BACKGROUND: Colorectal cancer (CRC) remains a major global health challenge, with increasing incidence, particularly among individuals under 50 years of age. Cathelicidin LL-37, a multifunctional antimicrobial peptide, has shown promise in cancer tre…
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 emergence of multidrug-resistant (MDR) bacterial pathogens is an alarming global health threat that demands new therapeutic strategies beyond conventional antibiotics. Here, we present a rationally designed antimicrobial peptide (AMP) derived fro…
