A New Cytotoxicity Assay for Brevetoxins Using Fluorescence Microscopy
Marine 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.

Brevetoxin PbTx2 Modulates Oxidative Stress and Inflammatory Response in an In Vitro Human Immune Cell Line [PDF]
ToxicsBrevetoxins (PbTx) exert detrimental effects on marine organisms and humans, mainly through alterations in immune cell function. This study evaluated the immunotoxic potential of sublethal concentrations of PbTx-2 using the THP-1 human monocyte cell line

Use of intravenous lipid emulsion therapy as a novel treatment for brevetoxicosis in sea turtles [PDF]
Scientific Reports, 2021 The southwest coast of Florida experiences annual red tides, a type of harmful algal bloom that results from high concentrations of Karenia brevis. These dinoflagellates release lipophilic neurotoxins, known as brevetoxins, that bind to sodium channels ...

When the Red Tide Rolls In: A Red Tide Associated Angioedema Case Report [PDF]
Clinical Practice and Cases in Emergency Medicine, 2021 Introduction: Histamine-mediated angioedema is a potentially life-threatening reaction following exposures that incite mast cell activation. In Florida, red tides are a frequent phenomenon caused by overgrowth of the harmful algae species Karenia brevis,
