Elucidation and reconstitution of hydrolyzable tannin biosynthesis

Plant Biotechnology
Hydrolyzable tannins (HTs) are a class of polyphenols produced mostly in core eudicot plants. They accumulate in various plant tissues and are considered to function as defense compounds that protect against herbivory, infections, and toxic metals (specifically aluminum ions).

Hydrolyzable and condensed tannins resistance in Clostridium perfringens

Anaerobe, 2015
Tannins added in the diet are being used to improve nutrition and health in farm animals as an alternative to antibiotic growth promoters and to control enteric clostridial diseases. However, the capacity of Clostridium perfringens to develop resistance under the selective pressure of tannins is unknown. The purpose of this study was to determine if C.

VEGETABLE TANNINS, RUMINAL MICROBIOTA AND RUMINANT METABOLISM INTERACTION

Tropical and Subtropical Agroecosystems, 2021
Background. Tannins, as polyphenolic secondary metabolites of plants, are attributed both beneficial and adverse functions when they are consumed by animals, effects that depend on the chemical structure and the concentration used.

Salivary proline-rich protein may reduce tannin-iron chelation: a systematic narrative review

Nutrition & Metabolism, 2017
Background Tannins are often cited for antinutritional effects, including chelation of non-heme iron. Despite this, studies exploring non-heme iron bioavailability inhibition with long-term consumption have reported mixed results.

Insecticidal Activity of Tannins from Selected Brown Macroalgae against the Cotton Leafhopper Amrasca devastans

Plants, 2023
Seaweeds, also known as marine macroalgae, are renewable biological resources that are found worldwide and possess a wide variety of secondary metabolites, including tannins. Drifted brown seaweed (DBSW) is particularly rich in tannins and is regarded as

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are
