Cyclic and acyclic defensins inhibit human immunodeficiency virus type-1 replication by different mechanisms. [PDF]

PLoS ONE, 2010
Defensins are antimicrobial peptides expressed by plants and animals. In mammals there are three subfamilies of defensins, distinguished by structural features: alpha, beta and theta. Alpha and beta-defensins are linear peptides with broad anti-microbial

Targeting Amastigote and Trypomastigote Phases: Multi‐Epitope Vaccine Strategy Against Trypanosoma cruzi

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Effective vaccines against Trypanosoma cruzi, the causative agent of Chagas disease, are urgently needed. Here, we report the design and in silico validation of a novel multiepitope vaccine construct targeting the key surface proteins ASP‐2 and gp82. Using a comprehensive immunoinformatics pipeline, we identified and selected 38 potent T‐cell (

Bioactive compounds in insects—Composition, extraction, functionality, food applications, and safety concerns

Food Biomacromolecules, EarlyView.
This review synthesizes 94 studies (2000–2025) exploring edible insects as sustainable sources of peptides, lipids, and chitin. Utilizing “green” extraction, these bioactives offer antioxidant and antimicrobial benefits for functional foods. However, addressing safety concerns like allergenicity and heavy metals through standardized frameworks remains ...

N6‐Methyladenosine in Inflammatory Bowel Disease: An Emerging Regulator of Pathogenesis and a Novel Therapeutic Frontier

iMetaMed, EarlyView.
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the intestine associated with an imbalance in intestinal homeostasis. m6A‐modifying enzymes, consisting of m6A writers, erasers and readers, plays a pivotal role in the pathogenesis and progression of IBD by affecting four intestinal barriers, including the intestinal mechanical ...

The gut microbiome organ

iMeta, EarlyView.
The gut microbiome can be conceptualized as a distributed organ‐like functional system with spatially structured organization, broad biochemical capacity, and continuous bidirectional communication with the host. By transforming dietary, host‐derived, and environmental substrates into bioactive metabolites with endocrine‐like, immunomodulatory, and ...
