The Human Cathelicidin LL-37 Preferentially Promotes Apoptosis of Infected Airway Epithelium [PDF]

American Journal of Respiratory Cell and Molecular Biology, 2010
Cationic host defense peptides are key, evolutionarily conserved components of the innate immune system. The human cathelicidin LL-37 is an important cationic host defense peptide up-regulated in infection and inflammation, specifically in the human lung, and was shown to enhance the pulmonary clearance of the opportunistic pathogen Pseudomonas ...

Cathelicidin: Insights into Its Impact on Metabolic Syndrome and Chronic Inflammation

Metabolites
Background/Objectives: LL-37 is associated with metabolic syndrome (MetS), a constellation of risk factors comprising obesity, insulin resistance (IR), dyslipidemia, and hypertension, which elevates the risk of cardiovascular disease and type 2 diabetes.

Role of Antimicrobial Peptides in the Pathogenesis of Atopic Dermatitis

The Journal of Dermatology, EarlyView.
ABSTRACT Atopic dermatitis (AD) is a chronic inflammatory skin disorder characterized by barrier dysfunction, immune dysregulation, and microbial dysbiosis. Recent studies have highlighted the multifaceted roles of antimicrobial peptides (AMPs) both as innate defenders against microbial invasion and as regulators of immune responses and skin barrier ...

Lung organoids as a human system for Mycobacteria infection modeling and drug testing

The FEBS Journal, EarlyView.
Mycobacterial infections, including tuberculosis (TB) and infections by nontuberculous mycobacteria (NTM), are still public health issues. In 2023, TB caused 1.25 million deaths, while NTM remain a clinical challenge for patients with cystic fibrosis (CF).

Antimicrobial peptide LL-37 and recombinant human mannose-binding lectin express distinct age- and pathogen-specific antimicrobial activity in human newborn cord blood in vitro [PDF]

, 2018
Background: There is a need to prevent and treat infection in newborns. One approach is administration of antimicrobial proteins and peptides (APPs) such as LL-37, a membrane-active cathelicidin antimicrobial peptide, and mannose-binding lectin (MBL), a ...

Antimicrobial Peptides and Skin: A Paradigm of Translational Medicine [PDF]

, 2012
Antimicrobial peptides (AMPs) are small, cationic, amphiphilic peptides with broad-spectrum microbicidal activity against both bacteria and fungi. In mammals, AMPs form the first line of host defense against infections and generally play an important ...

The exposomal imprint on rosacea: More than skin deep

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Rosacea reflects systemic and environmental interactions, not just a skin disorder. Key factors include environmental triggers, genetic and microbiome influences, diagnostic gaps in skin of colour and social determinants. Advances in multi‐omics and exposome integration highlight pathways towards precision medicine, prevention and equitable, patient ...
