Diversity of coelomocytes in the class Echinoidea (Echinodermata): A comparative study based on morphological evidence [PDF]

Comparative Immunology Reports
Echinoidea is, by far, the most known echinoderm class regarding the coelomocytes and their physiological functions. However, a careful examination shows that most data deal with regular echinoids (sea urchins), leaving a gap regarding the irregular ...

Coelomocytes of the Oligochaeta earthworm Lumbricus terrestris (Linnaeus, 1758) as evolutionary key of defense: a morphological study

Zoological Letters, 2023
Metazoans have several mechanisms of internal defense for their survival. The internal defense system evolved alongside the organisms. Annelidae have circulating coelomocytes that perform functions comparable to the phagocytic immune cells of vertebrates.

Endocytic coelomocytes are required for lifespan extension by axenic dietary restriction

PLoS ONE, 2023
A rather peculiar but very potent means of achieving longevity is through axenic dietary restriction (ADR), where animals feed on (semi-)defined culture medium in absence of any other lifeform.

Immune Protective Effect of Chitosan Oligosaccharide on Lipopolysaccharide-Stimulated Coelomocytes of Sea Cucumber <i>Apostichopus japonicus</i> In Vitro. [PDF]

Polymers (Basel)
In recent years, chitosan oligosaccharide (COS) has demonstrated promising applications in enhancing the immune protective function of sea cucumbers. However, the immune-protective effect of COS on sea cucumber coelomocytes in vitro remains unclear. This

Expanded polystyrene microplastic is more cytotoxic to seastar coelomocytes than its nonexpanded counterpart: A comparative analysis

Journal of Hazardous Materials Letters, 2021
Microplastics (MPs) are established contaminants of coastal ecosystem. Present investigation is aimed to assess comparative toxicity of polystyrene microplastic (PS-MP) and expanded polystyrene microplastic (EPS-MP) in the coelomocytes of Astropecten ...

Carotenoid-based immune response in sea cucumbers relies on newly identified coelomocytes—the carotenocytes [PDF]

Frontiers in Immunology
Sea cucumbers are marine deuterostomes possessing a complex innate immune system composed of a wide diversity of immune cells—coelomocytes—making them compelling models for exploring the evolution of immunity.
