Establishment of the immunological self in juvenile Patiria pectinifera post-metamorphosis

open access: yesFrontiers in Immunology, 2022
Ontogeny of the immune system is a fundamental immunology issue. One indicator of immune system maturation is the establishment of the immunological self, which describes the ability of the immune system to distinguish allogeneic individuals ...

Sex-Specific Transcriptomic Differences in the Immune Cells of a Key Atlantic-Mediterranean Sea Urchin

open access: yesFrontiers in Marine Science, 2022
The abundance of the black sea urchin, Arbacia lixula, has been increasing during the last decades likely related to global warming. This thermophilous species has a leading role in maintaining marine barrens in the Mediterranean with the consequent ...

Combining computer vision and standardised protocols for improved measurement of live sea urchins for research and industry

open access: yesAquaculture, Fish and Fisheries, Volume 3, Issue 6, Page 507-517, December 2023., 2023
In this paper, we find the currently applied sea urchin measurement techniques are not standardized, have high measurement errors and are labour‐intensive. Therefore, we develop a protocol requiring no specialised equipment and open‐source software that precisely and rapidly quantifies urchin wet mass and diameter.

Highly efficient optogenetic cell ablation in C. elegans using membrane-targeted miniSOG. [PDF]

open access: yes, 2016
The genetically encoded photosensitizer miniSOG (mini Singlet Oxygen Generator) can be used to kill cells in C. elegans. miniSOG generates the reactive oxygen species (ROS) singlet oxygen after illumination with blue light.

Localization of relaxin‐like gonad‐stimulating peptide expression in starfish reveals the gonoducts as a source for its role as a regulator of spawning

open access: yesJournal of Comparative Neurology, Volume 531, Issue 13, Page 1299-1316, September 2023., 2023
Oocyte maturation and release (spawning) in starfish are triggered by relaxin‐like gonad‐stimulating peptide (RGP), which exerts its effects by stimulating ovarian follicle cells to produce 1‐methyladenine. Here, we present evidence that gonoducts (Gd) located proximal to the ovaries (O) are the physiological source of RGP that triggers spawning in ...
