The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
PURPOSE: To study the angiogenic capacity of antimicrobial peptide LL37 (cathelicidin antimicrobial peptide), explore its molecular mechanisms, and provide new ideas for treating lower limb ischemic diseases. METHODS: LL37 was applied exogenously to…
Psoriasis is an immune-mediated inflammatory disorder, where the majority of the patients suffer from psoriasis capitis or scalp psoriasis. Current therapeutics remain ineffective to treat scalp lesions. In this study, we present a whole-metagenome c…
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…
The interactions between peptides and lipids are fundamental for many biological processes. Therefore, exploring the noncovalent interactions that govern these interactions has become increasingly important. Native mass spectrometry is a valuable tec…
BACKGROUND: Diabetic urinary incontinence is a multifactorial condition involving neuropathy, oxidative stress, and epithelial dysfunction. Serum biomarkers-cathelicidin (LL-37), elafin, vitamin D receptor (VDR), 4-hydroxynonenal (4-HNE), and amyloid…
Tuberculosis (TB), caused by members of the Mycobacterium tuberculosis complex, remains a critical global health challenge, affecting humans and a wide range of domestic and wild animals. Despite the availability of anti-TB drugs, cure rates remain s…
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…
The human cathelicidin LL-37 is active against both bacteria and viruses, but it also shows immunomodulatory properties. Here, we assess the impact of LL-37 on viral signaling in human airway epithelial BEAS-2B cells infected with the respiratory pat…
Current diagnostics for sepsis-associated acute kidney injury (SA-AKI) detect kidney damage only at advanced stages, limiting opportunities for timely intervention. A DNA origami-based nanoplatform is developed for the early diagnosis and treatment o…
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…
Globally, chronic wounds impact the health of millions of people, negatively affecting quality of life and healthcare budgets. Some of the crucial steps and pathways in healing mechanisms are the hypoxic response and the expression of host defence pe…
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…
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…
The increase in bacterial resistance to minocycline and other tetracyclines poses a serious threat to global public health. Because the development of new antibiotics has proven problematic, antibiotic sensitization therapy is now an effective coping…
Escalating antimicrobial resistance necessitates the development of alternative therapeutics that circumvent conventional enzymatic and efflux-based defence systems. Antimicrobial peptides (AMPs) represent a compelling class of innate immune effector…
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…
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…
Non-canonical functions of olfactory receptors, one of the largest families of GPCR receptors not confined to the olfactory system, include an intriguing role on hair physiology. Previous studies using odorant agonists of the Olfactory Receptor famil…
Cathelicidin-BF (CatBF) is a LL-37 homologous antimicrobial peptide (AMP) isolated fromwith an exceptional portfolio of antimicrobial, antiviral, antifungal, and anticancer activities. Contrary to many AMPs, it showed a good pharmacological profile w…
BACKGROUND: Sputum extracellular DNA (eDNA) is associated with disease severity in asthma and COPD and therefore emerging as a potential therapeutic target. The aim of this study was to investigate the effect of 10 days of recombinant human DNase (rh…
