Snake venom defensins: Defining the structural and functional characteristics of the toxin family

Journal of Structural Biology: X
Snake venom defensins are a toxin family found in rattlesnake venoms (Crotalus) which are comprised of crotamine-like peptides and myotoxins. Their tertiary structure resembles the β-defensin family structure.

Dietary modulation of antimicrobial peptides (HAMP and LEAP2) in Chinook salmon (Oncorhynchus tshawytscha) fed a phytobiotic functional diet: Integrated genomic characterisation and tissue‐specific expression

Journal of Fish Biology, EarlyView.
Abstract Antimicrobial peptides (AMPs) are key components of the innate immune system in fish, providing rapid protection against microbial pathogens. Among these, the liver‐expressed antimicrobial peptides (LEAPs), comprising LEAP‐1 (hepcidin; HAMP) and LEAP‐2, play central roles in host defence and iron regulation.

L‐Glutamine Plus L‐Glutamic Acid Enhances Antioxidant Status and Ammonia Toxicity Resilience, Upregulates Interleukin IL‐10 Gene, and Improves Gut Microbiota and Survival in Juvenile Nile Tilapia

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Glutamine (Gln) and glutamic acid (Glu) are the most abundant free amino acids (AAs) in the fish body. Although classified as non‐essential AAs, their supplementation can be a strategy to optimize the growth performance and health of fish.

Genetic Susceptibility to Periodontitis

Journal of Periodontal Research, EarlyView.
Aim: The aim of this narrative review was to identify genes carrying risk alleles associated with an increased risk of periodontitis and to place them in a biological context. Methods: The literature was reviewed based on predefined criteria. Results: The identified genes largely fall into functions linking immune response with tissue repair. The genes

[Scorpion toxins and defensins].

Comptes rendus des seances de la Societe de biologie et de ses filiales, 1998
Les venins de scorpion contiennent un grand nombre de neurotoxines peptidiques qui constituent un ensemble de familles molécu­laires à haut degré de polymorphisme, mais qui ont en commun une architecture semblable. Cette architecture se retrouve dans des peptides antibactériens circulants de la famille des défensines, qui s'apparentent tout ...

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.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Inflammation and mechanical force‐induced bone remodeling

Periodontology 2000, EarlyView.
Abstract Periodontitis arises from imbalanced host–microbe interactions, leading to dysbiosis and destructive inflammation. The host's innate and adaptive immune responses produce pro‐inflammatory mediators that stimulate destructive events, which cause loss of alveolar bone and connective tissue attachment.

Ideal soft tissue graft in periodontal and peri‐implant applications: A scoping review

Periodontology 2000, EarlyView.
Abstract Soft tissue grafts (STG) are used in a wide range of clinical situations including volume augmentation, keratinized tissue increase, and recession coverage around teeth and implants. Each STG, produced from different sources and processed with various techniques, possesses unique material properties and interaction with the host tissues, which

Avian Eggshell Evolutionary Adaptations Inform Biomimetic Strategies for Next‑Generation Precision Cancer Theranostics

Advanced Oncology, Volume 1, Issue 1, December 2026.
ABSTRACT The avian eggshell is a sophisticated, multi‐functional biocomposite and, more importantly, an autonomous life‐support system evolved to safeguard embryonic development across dynamic and hostile environments. Discussing eggshell‐inspired biomaterials beyond simple structural imitation, this review translates these evolutionary survival ...
