| Abstract |
In crustaceans, major physiological functions such as homeostasis, growth or reproduction are regulated by neurohormones elaborated in the major neuroendocrine center: the X-organ-sinus gland (XO-SG) complex. In Decapoda, this complex is usually located within the eyestalks. The major neurohormone elaborated by the XO-SG complex is cHH (crustacean hyperglycemic hormone), a polymorphic and multifunctional neurohormone which is considered as a stress hormone since the primary response of animals to an exposure to stressing situations (hypoxia, hyperthermia, handling... ) consists in hyperglycemia consecutive to cHH release. Characterization of the neurosecretory system and neurohormone structure in crustaceans adapted to the extreme conditions of the deep-sea hydrothermal vents was undertaken to gather informations in different fields such as hormone evolution or adaptative physiology. Pacific deep hydrothermal vents crabs Bythograea thermidron were collected during the HOT cruise. |
