Serum LL‐37 and inflammatory cytokines levels in psoriasis [PDF]

Immunity, Inflammation and Disease, 2023
Background Psoriasis (PsO) is a T‐cell‐associated inflammatory autoimmune dermatitis. Leucine leucine‐37 (LL‐37) is upregulated in PsO patients and correlated with the area and severity of PsO.

LL-37 and citrullinated-LL-37 modulate IL-17A/F-mediated responses and selectively suppress Lipocalin-2 in bronchial epithelial cells [PDF]

Journal of Inflammation
Background Levels of the human cationic antimicrobial host defence peptide LL-37 are enhanced in the lungs during neutrophilic airway inflammation. LL-37 drives Th17 differentiation, and Th17 cells produce IL-17A and IL-17F which form the biologically ...

LL-37 and citrullinated-LL-37 enhances oxylipins: citrullination attenuates LL-37-mediated COX-2-dependent chemokine response in human bronchial epithelial cells [PDF]

Respiratory Research
Background During airway inflammation, chemokines, oxylipins (bioactive lipids) and cationic host defence peptides (CHDP) are enhanced in the lungs. However, the interplay of these molecules in the process of airway inflammation is not fully resolved ...

Elevated LL-37/FPR2 Axis and its Regulatory Role for Gingival Fibroblasts in Periodontitis [PDF]

International Dental Journal
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.

Adaptive immune response to the autoantigen LL‐37 differentiates atherosclerotic cardiovascular disease phenotypes [PDF]

Clinical & Translational Immunology
Atherosclerosis is the common underlying pathology in atherosclerotic cardiovascular disease (ASCVD) phenotypes of myocardial infarction (MI), stroke or peripheral artery disease (PAD). Single immune cell profiling of atherosclerotic plaques demonstrates

Glioblastoma Multiforme: Sensitivity to Antimicrobial Peptides LL-37 and PG-1, and Their Combination with Chemotherapy for Predicting the Overall Survival of Patients [PDF]

Pharmaceutics
Background/Objectives: Glioblastomas (GBMs) are the most malignant and intractable of all cancers, with an unfavorable clinical prognosis for affected patients. The objective was to analyze the sensitivity of GBM cells to the antimicrobial peptides (AMPs)

A Novel Pathway of Platelet Activation in ACS Mediated by LL-37 Immunoglobulin G Autoantibody Immune Complexes [PDF]

JACC: Basic to Translational Science
Summary: The cathelicidin antimicrobial peptide LL-37 is a self-antigen in neutrophil extracellular traps that provokes autoantibody responses in autoimmune/autoinflammatory conditions.

The antibacterial effect of human adipose-derived stem cells on LL-37-resistant bacteria. [PDF]

PLoS ONE
Human adipose-derived stem cells (hADSCs) exhibit antibacterial properties, but their effectiveness against bacteria resistant to LL-37- a natural human antimicrobial peptide important in the immune defense- is not fully understood.

LL-37 Attenuates Sepsis-Induced Lung Injury by Alleviating Inflammatory Response and Epithelial Cell Oxidative Injury via ZBP1-Mediated Autophagy [PDF]

Toxins
Background: 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.
