Response of common carp (Cyprinus carpio L.) leucocytes to hormone-induced stress

Physiological and proteomic responses to corticosteroid treatments in Eurasian perch, Perca fluviatilis : Investigation of immune-related parameters

“…The effects of these corticosteroid hormones are mediated by intracellular receptors that act as ligand-dependent transcription factors. Under the current paradigm, cortisol binds to either glucocorticoid receptors (GR) or mineralocorticoid receptors (MR) whereas DOC appears to 2 act only via the MR (Sturm et al, 2005;Arterbery et al, 2011). Whereas cortisol has been shown for a long time to exert pleiotropic actions, the physiological roles of DOC in teleosts are still poorly understood.…”

Evaluation of hematological and plasma indices in grass carp, Ctenopharyngodon idella, with reference to age, sex, and hormonal treatment

“…Similarly to our results, no differences in biochemical indexes were observed between two groups of tench females treated with GnRH analog and carp pituitary extract (Kouril et al 2007). It is reported that differences in plasma indexes in response to hormonal treatments could stem from species differences, the type of hormone administered, fish maturity, and also species sensitivity to injection stress (Luskova 1998, Hrubec et al 2001, Öner et al 2008, Balabanova et al 2009. Balabanova et al (2009) report increases in WBC in response to dexametazone phosphate (a synthetic hormone); thus, increases in the percentage of lymphocytes and eosinophils in our study could be related to injection stress.…”

The Effect of Phenanthrene on Some Hematological Indices Yellowfin Seabream (Acanthopagrus Latus)

“…The differentiation of immune cells in hemopoietic organs was suppressed in common carp with high plasma level of cortisol; however, myeloid cell production increased in these fish [32]. It was possible because of the decrease in the cytokine synthesis responsible for regulating the differentiation processes of lymphomyeloid cells [32].…”
