Mode of action of Cr(VI) in immunocytes of earthworms: Implications for animal health [PDF]

, 2017
Chromium (Cr) is one of the major and most detrimental pollutant, widely present in the environment as a result of several anthropogenic activities. In mammalian cells, Cr(VI) is known to enhance reactive oxygen species (ROS) production and to cause ...

The physiological stress response to amputation in the eleven-armed sea star (Coscinasterias muricata) : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Zoology, Massey University, Palmerston North, New Zealand [PDF]

, 2016
The eleven-armed sea star, Coscinasterias muricata, is subject to human-induced stressors, such as invasive fishing activities, that can cause limb loss (amputation), and heavy metal discharge into their habitat.

Effects of PAHs and dioxins on the earthworm Eisenia andrei: a multivariate approach for biomarker interpretation. [PDF]

, 2014
In this study, a battery of biomarkers was utilised to evaluate the stress syndrome induced in the earthworm Eisenia andrei by exposure to environmentally realistic concentrations of benzo[a]pyrene (B[a]P) and 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD)

A Nuclear Hormone Receptor nhr‐76 Induces Age‐Dependent Chemotaxis Decline in C. elegans

Aging Cell, Volume 24, Issue 12, December 2025.
A forward genetic screen in C. elegans identified a nuclear hormone receptor, nhr‐76, as a gene that programs age‐dependent behavioral decline. In post‐reproductive adults, NHR‐76 downregulates odr‐10 that encodes an odorant receptor, leading to impaired chemotaxis.

STUDIES ON HOLOTHURIAN COELOMOCYTES. I. A SURVEY OF COELOMOCYTE TYPES

The Biological Bulletin, 1963
1. The coelomocytes of eleven species of holothurians, representing four orders, were surveyed and described. Eight of these species have not before been surveyed for their coelomocyte contents.2. The results of the investigation indicate that holothurian coelomocytes fall into five basic categories: hemocytes, amoebocytes, morula calls, lymphocytes ...

Structural analysis of an Asterias rubens peptide indicates the presence of a disulfide‐directed β‐hairpin fold

FEBS Open Bio, Volume 15, Issue 3, Page 415-426, March 2025.
Sea stars have remarkable regenerative capabilities. A peptide, KASH2, identified in the biofluid of the common sea star Asterias rubens appears to be involved with the wound‐healing response in the organism. Here, we show the 3D structure of KASH2 adopts a disulfide‐directed β‐hairpin fold, a fold only previously found in arachnids, and does not show ...

Coelomocyte populations in the sea urchin, Strongylocentrotus purpuratus, undergo dynamic changes in response to immune challenge

Frontiers in Immunology, 2022
The sea urchin, Strongylocentrotus purpuratus has seven described populations of distinct coelomocytes in the coelomic fluid that are defined by morphology, size, and for some types, by known functions. Of these subtypes, the large phagocytes are thought

Gender differences in the immune system activities of sea urchin Paracentrotus lividus [PDF]

, 2013
In the immune system of vertebrates, gender-specific differences in individual immune competence are well known. In general, females possess more powerful immune response than males. In invertebrates, the situation is much less clear. For this purpose we
