Molecular Determinants of Brevetoxin Binding to Voltage-Gated Sodium Channels

open access: yesToxins, 2019
Brevetoxins are produced by dinoflagellates such as Karenia brevis in warm-water red tides and cause neurotoxic shellfish poisoning. They bind to voltage-gated sodium channels at neurotoxin receptor 5, making the channels more active by shifting the ...

Discovery of a Potential Human Serum Biomarker for Chronic Seafood Toxin Exposure Using an SPR Biosensor

open access: yesToxins, 2019
Domoic acid (DA)-producing harmful algal blooms (HABs) have been present at unprecedented geographic extent and duration in recent years causing an increase in contamination of seafood by this common environmental neurotoxin. The toxin is responsible for

Brevenal inhibits pacific ciguatoxin-1B-induced neurosecretion from bovine chromaffin cells.

open access: yesPLoS ONE, 2008
Ciguatoxins and brevetoxins are neurotoxic cyclic polyether compounds produced by dinoflagellates, which are responsible for ciguatera and neurotoxic shellfish poisoning (NSP) respectively. Recently, brevenal, a natural compound was found to specifically

Calcium Increase and Substance P Release Induced by the Neurotoxin Brevetoxin-1 in Sensory Neurons: Involvement of PAR2 Activation through Both Cathepsin S and Canonical Signaling

open access: yesCells, 2020
Red tides involving Karenia brevis expose humans to brevetoxins (PbTxs). Oral exposition triggers neurotoxic shellfish poisoning, whereas inhalation induces a respiratory syndrome and sensory disturbances.

Neurotoxic Alkaloids: Saxitoxin and Its Analogs

open access: yesMarine Drugs, 2010
Saxitoxin (STX) and its 57 analogs are a broad group of natural neurotoxic alkaloids, commonly known as the paralytic shellfish toxins (PSTs). PSTs are the causative agents of paralytic shellfish poisoning (PSP) and are mostly associated with marine ...

Evolution and Distribution of Saxitoxin Biosynthesis in Dinoflagellates

open access: yesMarine Drugs, 2013
Numerous species of marine dinoflagellates synthesize the potent environmental neurotoxic alkaloid, saxitoxin, the agent of the human illness, paralytic shellfish poisoning.

Microbial communities and functional diversity in seafood

open access: yesJSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

A New Cytotoxicity Assay for Brevetoxins Using Fluorescence Microscopy

open access: yesMarine Drugs, 2014
Brevetoxins are a family of ladder-framed polyether toxins produced during blooms of the marine dinoflagellate, Karenia brevis. Consumption of shellfish or finfish exposed to brevetoxins can lead to the development of neurotoxic shellfish poisoning.

Biosensors for Biotoxins Detection and Monitoring

open access: yesAdvanced Sensor Research, Volume 5, Issue 6, June 2026.
This review examines state‐of‐the‐art biosensing platforms for biotoxin detection, including antibody‐, aptamer‐, CRISPR‐, nanopore‐, whole cells‐ and MIP‐based sensors. It highlights advances in ultra‐sensitive detection, real‐matrix validation in food and water, and multiplexed analysis, and discusses how the integration with machine learning ...

Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

open access: yesEFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).
