The ichthyotoxic dinoflagellate Karlodinium veneficum has a worldwide distribution and produces highly potent lytic toxins (karlotoxins) that have been associated with massive fish kill events in coastal environments. The capacity of K. veneficum to gain energy from photosynthesis as well as phagotrophy enables cellular maintenance, growth and disp...

The oxidation of polyunsaturated fatty acids (PUFA) is a common stress response across biomes with potential to trigger impairment of cell growth and reproduction. The oxidative stress theory of coral bleaching induced by global warming has been widely accepted to explain coral reef decline, but its underlying physiological mechanism remains under...

Coral bleaching caused by ocean warming is leading to worldwide coral decline. The physiological processesunderlying this ecological event are still incompletely understood, although previous research has suggested oxi-dative stress as major player in the impairment of symbiont thylakoid membranes and in symbiosis breakdown.Lipids are interesting t...

Oxylipin signaling has been suggested as a potential mechanism for the inter-partner recognition and homeostasis regulation of cnidarian-dinoflagellate symbiosis, which maintains the ecological viability of coral reefs. Here we assessed the effects of symbiosis and symbiont identity on a model cnidarian, the sea anemone Exaiptasia diaphana , using...

COVID-19 virus likely infects the brain causing irreversible damage. We suggest that it might be a consequence of energy stress, which is well known to be the trigger of death cascades. This view opens new treatment strategies for compromised patients. Once again, the devil is in the details. Figure 1: Several human lipid viruses, including the nov...

Coral reefs around the world have been largely devastated by the phenomenon of “coral bleaching”, which causes have been reported to be strongly related to oxidative stress promoted by climate change drivers, including mainly global warming and catastrophic El Niño events. Genetic variability in coral endosymbionts from the Family Symbiodiniacea wa...
