Probable Microcystin Toxicosis in a Red-Gartered Coot (Fulica armillata) from a Protected Coastal Wetland in Central Chile—A Sentinel for Toxic Cyanobacterial Bloom?

Veterinary Sciences
Cyanobacterial harmful algal blooms are an increasing concern for wildlife health, particularly in eutrophic wetlands, yet well-documented avian cases supported by environmental, pathological, and toxicological evidence remain scarce.

Safety evaluation of blue galdieria extract as a food additive

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract The EFSA Panel on Food Additive and Flavourings (FAF Panel) provides a scientific opinion on the safety of blue galdieria extract as a food additive. Blue galdieria extract is an enzymatically treated C‐phycocyanin extract derived from the lysed biomass of the microalgae Galdieria sulphuraria.

Noncompetitive Chromogenic Lateral-Flow Immunoassay for Simultaneous Detection of Microcystins and Nodularin

Biosensors, 2019
Cyanobacterial blooms cause local and global health issues by contaminating surface waters. Microcystins and nodularins are cyclic cyanobacterial peptide toxins comprising numerous natural variants.

Microcystin-LR Induces Alterations in Heart Muscle

Folia Biologica, 2006
MC-LR belongs to a family of cyanobacterial toxins. MC-LR acts as serine-threonine phosphatase-1 and -2A inhibitor. Chronic intoxication with low doses of this toxin promotes liver tumour formation and induces kidney injury. The aim of the study was to evaluate whether chronic exposure to relatively low doses of MC-LR has toxic ...

Absence of Cyanotoxins in Llayta, Edible Nostocaceae Colonies from the Andes Highlands

Toxins, 2020
Edible Llayta are cyanobacterial colonies consumed in the Andes highlands. Llayta and four isolated cyanobacteria strains were tested for cyanotoxins (microcystin, nodularin, cylindrospermopsin, saxitoxin and β-N-methylamino-L-alanine—BMAA) using ...

Haematology of Clarias gariepinus exposed to Microcystin-LR

Beni-Suef University Journal of Basic and Applied Sciences, 2017
A static bioassay experiment was conducted by exposing Clarias gariepinus to 200 µg/L and 400µ/L of MC-LR solutions for 14 days and 28 days to assess the haematological impacts such as estimation of red blood cells, white blood cell and Thrombocytes, haemoglobin percentage, haematocrit, and percentage changes.

Multiomic single nuclei profiling the mouse hippocampus reveals that ACSS2 confers neuronal resilience to tauopathy

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Epigenomic dysregulation contributes to Alzheimer's disease (AD) and related tauopathies. Acetyl‐CoA synthetase 2 (ACSS2), a nuclear‐localized metabolic enzyme in neurons, supports histone acetylation and learning‐related gene expression.

Hepatocyte apoptosis is triggered by hepatic inflammation in common carp acutely exposed to microcystin-LR or chronically exposed to Microcystis

Ecotoxicology and Environmental Safety
Cyanobacterial blooms pose a serious threat to the survival of fish because of the hepatotoxicity of microcystins produced by toxic cyanobacteria such as Microcystis.
