Sea Urchin Pigments: Echinochrome A and Its Potential Implication in the Cytokine Storm Syndrome [PDF]
Marine Drugs, 2021 Background: Echinochrome A (EchA) is a pigment from sea urchins. EchA is a polyhydroxylated 1,4-naphthoquinone that contains several hydroxyl groups appropriate for free-radical scavenging and preventing redox imbalance. EchA is the most studied molecule

THE EXTRACELLULAR RELEASE OF ECHINOCHROME [PDF]
Journal of General Physiology, 1946 A study was made of the diffusion of the red pigment echinochrome from the eggs of the sea urchin, Arbacia punctulata, into sea water. Unfertilized eggs retained their pigment, over periods of hours. Outward diffusion of pigment from unfertilized eggs normally is entirely negligible, or does not occur at all.

Echinochrome A Release by Red Spherule Cells Is an Iron-Withholding Strategy of Sea Urchin Innate Immunity [PDF]
, 2018 Cellular immune defences in sea urchins are shared amongst the coelomocytes – a heterogeneous population of cells residing in the coelomic fluid (blood equivalent) and tissues. The most iconic coelomocyte morphotype is the red spherule cell (or amebocyte)
