Lignin Nanoparticles Containing Cobalt‐Cyanine Complexes: Potential Multifunctional Platforms for Photoacoustic Imaging and Photothermal Treatment of Bacterial Biofilms in Chronic Wounds

Macromolecular Bioscience, Volume 26, Issue 2, February 2026.
CoPc is combined with a lignin‐based material to obtain NPs sensitive to NIR irradiation and capable of ROS scavenging. Through the NPs, mild photothermal therapy can be achieved to act against bacterial biofilms. ABSTRACT Chronic wounds (CWs) are characterized by persistent inflammation and bacterial biofilms, which hinder healing and contribute to ...

Twists and Turns of Liquid Crystals Unravelled by Small‐Angle Scattering

Small Methods, Volume 10, Issue 3, 9 February 2026.
X‐ray scattering provides valuable insights into material structure and self‐assembly. This review discusses the use of small‐ and wide‐angle X‐ray scattering (SWAXS) as well as grazing incident SWAXS for examining self‐assembled systems, especially liquid crystals.

No difference in inflammatory mediator expression between mast cell-rich and mast cell-poor rosacea lesions in Korean patients: a comparative study [PDF]

The Ewha Medical Journal
Objectives: This study aimed to evaluate the correlation between mast cell (MC) density in rosacea-affected skin and the expression of key inflammatory mediators, including IL-6, TNF-α, and cathelicidin LL-37.

Alanylation of Teichoic Acids Protects Staphylococcus aureus against Toll-like Receptor 2-Dependent Host Defense in a Mouse Tissue Cage Infection Model [PDF]

, 2017
Staphylococcus aureus is inherently resistant to cationic antimicrobial peptides because of alanylation of cell envelope teichoic acids. To test the effect of alanylated teichoic acids on virulence and host defense mediated by Toll-like receptor 2 (TLR2),

Influence of maternal nutrition and one-carbon metabolites supplementation on bovine antimicrobial peptides in fetal and maternal tissues

Frontiers in Veterinary Science
IntroductionMaternal nutrition during pregnancy critically influences offspring development and immune function. One-carbon metabolites (OCM) are epigenetic modifiers that may modulate antimicrobial peptide (AMP) expression, which is vital for innate ...

Imaging the Antistaphylococcal Activity of CATH-2: Mechanism of Attack and Regulation of Inflammatory Response

mSphere, 2017
Chicken cathelicidin-2 (CATH-2) is a broad-spectrum antimicrobial host defense peptide (HDP) that may serve as a paradigm for the development of new antimicrobial agents.

[Cathelicidins - endogenous antimicrobial peptides].

Postepy biochemii, 2015
Within the last decade, several antimicrobial peptides (AMPs) have been discovered. Cathelicidins are one family of AMPs characterized by a conserved cathelin domain and a variable C-terminal cationic antimicrobial domain. These peptides are produced by different cells, including leukocytes, epithelial cells and keratinocytes.

Current Status of Defensins and Their Role in Innate and Adaptive Immunity [PDF]

, 2002
Naturally occurring antimicrobial cationic polypeptides play a major role in innate and adaptive immunity. These polypeptides are found to be either linear and unstructured or structured through disulfide bonds.

Antimicrobial Peptides: Their Role in Innate Immune System and Usage in Future Drug Development [PDF]

, 2015
Antimicrobial peptides naturally play a role in the innate immune system of any living organisms. These small molecules are known as "ancient weapon" and also recognized as natural antibiotics. Antimicrobial peptides have distinct characteristics
