Mechanisms of recalcitrant fucoidan breakdown in marine Planctomycetota

Nature Communications
Marine brown algae produce the highly recalcitrant polysaccharide fucoidan, contributing to long-term oceanic carbon storage and climate regulation. Fucoidan is degraded by specialized heterotrophic bacteria, which promote ecosystem function and global ...

Impact of Positively Charged Backbone Modifications on the Properties of Spherical Nucleic Acids

Small, EarlyView.
A synthesis of spherical nucleic acids (SNAs) featuring cationic backbone modifications is presented, together with an analysis of their emerging properties. Introducing positively charged guanidinium groups near the SNA surface enhances cellular uptake and offers a pathway toward more precise control over SNA internalization.

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.

Dietary Supplementation with Low-Molecular-Weight Fucoidan Enhances Innate and Adaptive Immune Responses and Protects against Mycoplasma pneumoniae Antigen Stimulation

Marine Drugs, 2019
In this study, the low-molecular-weight (LMW) fucoidan, rich in fucose and sulfate, was extracted and purified from the edible brown seaweed, Laminaria japonica. In this study, we orally administered LMW fucoidan to mice for 6 weeks.

Insights Into the Antibiofilm Activity of Carbon Quantum Dots Against a Panel of Different Microorganisms: A Review

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Carbon quantum dots (CDs) have emerged as versatile nanoplatforms for combating biofilm‐associated infections through multiple mechanisms, including EPS disruption, membrane damage, ROS generation, and quorum sensing inhibition. This review highlights how CD physicochemical properties and surface engineering strategies influence antibiofilm activity ...
