Cytotoxicity and intestinal permeability of phycotoxins assessed by the human Caco-2 cell model

Ecotoxicology and Environmental Safety, 2023
Phycotoxins are a class of multiple natural metabolites produced by microalgae in marine and freshwater ecosystems that bioaccumulate in food webs, particularly in shellfish, having a great impact on human health.

Plankton communities today and tomorrow—potential impacts of multiple global change drivers and marine heatwaves

Limnology and Oceanography, Volume 70, Issue S2, Page S225-S241, December 2025.
Abstract In the context of global change, marine organisms are subjected not only to gradual changes in abiotic parameters, but also to an increasing number of extreme events, such as heatwaves. However, we still know little about the influence of heatwaves on the structure of marine communities, and experimental studies are needed to test the impact ...

Metabolism of the lipophilic phycotoxin 13-Desmethylspirolide C using human and rat in vitro liver models

, 2019
International audience13-Desmethylspirolide C (13-SPX-C) is a phycotoxin produced by dinoflagellates which can accumulate in shellfish. 13-SPX-C induces neurotoxic effects in rodents through blockade of nicotinic acetylcholine receptors.

Grazer‐induced bioluminescence and toxicity in marine dinoflagellates

Limnology and Oceanography, Volume 70, Issue 12, Page 3769-3783, December 2025.
Abstract Marine copepods are the most abundant multicellular zooplankton in the global oceans. They imprint their surrounding waters with a unique bouquet of chemical compounds, including polar lipids such as copepodamides. Prey organisms can detect copepodamides and respond by inducing defensive traits including bioluminescence, toxin production ...

Sustained Heatwaves Reshape the Phytoplankton–Zooplankton Community Structure in Freshwater Ecosystems: A Case Study of Shengjin Lake

Ecology and Evolution, Volume 15, Issue 11, November 2025.
The sustained heatwave has shaped the plankton community structure and led to high‐temperature domestication of some of the plankton. Plankton communities have the ability to resist heatwave stress. The sustained heatwave has altered the interrelationships between plankton.

Diversity of Amphidomataceae (Dinophyceae) in the Black Sea, including description of Amphidoma pontica sp. nov.

Phycological Research, Volume 73, Issue 4, Page 225-248, October 2025.
SUMMARY The dinoflagellate family Amphidomataceae includes the genera Azadinium and Amphidoma, several species of which are known producers of lipophilic toxins known as azaspiracids (AZAs). However, the diversity, abundance, and distribution of this important group of nanoplanktonic dinoflagellates in the Black Sea remain poorly understood. To address

Detecção de ácido ocadaico em cultivo de mexilhões Perna perna, Angra dos Reis, RJ Okadaic acid detection in mussel cultivation Perna perna, Angra dos Reis, RJ

Ciência Rural, 2010
A ficotoxina ácido ocadaico (AO) é produzida por um grupo de microalgas conhecidas como dinoflagelados. Os mexilhões, ao se alimentarem dessas microalgas, acumulam a toxina em sua glândula digestiva, desencadeando a Síndrome ou Envenenamento Diarreico ...
