Effects of Probiotics on the Expression of Cathelicidins in Response to Stimulation by Salmonella Minnesota Lipopolysaccharides in the Proventriculus and Cecum of Broiler Chicks

The Journal of Poultry Science, 2016
The aim of this study was to determine whether probiotic-feeding affected the expression of cathelicidins (CATHs), a major family of antimicrobial peptides, in response to lipopolysaccharides (LPS) challenge in the proventriculus and cecum of broiler ...

A review of skin microbiome and new challenges to cosmetic microbiome‐friendly formulations

International Journal of Cosmetic Science, EarlyView.
Microbiome‐friendly concepts offer new perspectives for a healthy relationship between cosmetic use and the skin microbiome, especially the interaction of non‐biotic cosmetic ingredients with the skin, requiring further studies to clarify the dynamics between the skin microbiome and different classes of cosmetic ingredients.

Past, Present, and Future of Naturally Occurring Antimicrobials Related to Snake Venoms

Animals, 2023
This review focuses on proteins and peptides with antimicrobial activity because these biopolymers can be useful in the fight against infectious diseases and to overcome the critical problem of microbial resistance to antibiotics.

Plasma Elastase Screening in Hematological Disease Reveals Its Potential as a Diagnostic and Prognostic Biomarker in Hematological Malignancies

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction Neutrophil‐extracellular traps are net‐like material released by triggered neutrophils and composed of decondensed chromatin linked to nuclear proteins. Elastase, one of the fourth most represented neutrophil‐specific serine proteases stored in azurophil granules of naïve neutrophils, exerts various actions, including degradation ...

Inflammatory and Immunological Basis of Periodontal Diseases

Journal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

Novel Alligator Cathelicidin As-CATH8 Demonstrates Anti-Infective Activity against Clinically Relevant and Crocodylian Bacterial Pathogens

Antibiotics, 2022
Host defense peptides (HDPs) represent an alternative way to address the emergence of antibiotic resistance. Crocodylians are interesting species for the study of these molecules because of their potent immune system, which confers high resistance to ...

Autoimmunity and Periodontitis

Journal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

Antiviral Activity of Chicken Cathelicidin B1 Against Influenza A Virus

Frontiers in Microbiology, 2020
Cathelicidins (CATHs) are host defense peptides (HDPs) that play an important role in the innate immune response against infections. Although multiple functions of cathelicidins have been described, including direct antimicrobial activity and several ...
