Identification of differentially expressed genes and quantitative expression of complement genes in the liver of marine medaka Oryzias melastigma challenged with Vibrio parahaemolyticus

Physiological responses of reared sea bream (Sparus aurata Linnaeus, 1758) to an Amyloodinium ocellatum outbreak

“…This protein can also participate in inhibition of bacterial endotoxin, antiviral activity, antiinflammatory, anti-apoptotic role, inhibition of inflammatory cytokines, neutralization of LPS (Ulevitch, Johnston & Weinstein 1981;Johnston et al 2008) or associated with C3 complex in cod (Gadus morhua L.) (Magnadottir 2006) and in rainbow trout (Oncorhynchus mykiss Walbaum) (Villarroel et al 2007). The fact that usually an immune response is correlated with an increase or no change of ApoAI (Concha et al 2003(Concha et al , 2004Villarroel et al 2007;Bo et al 2012;Wu et al 2012) levels in plasma reinforces the possibility of an absence of response of the innate immune system to A. ocellatum, that is in agreement with the data obtained in HTC and differential blood cell count.…”

Fish Cytokines and Immune Response

“…Different works have been done with SSH to evaluate fish immune response at the gene expression level against challenges with bacteria-derived pathogen-associated molecular patterns (PAMP) like LPS [272,273] and whole bacteria like Aeromonas salmonicida [274,275], Listonella anguillarum [276], Edwardsiella tarda [277], and Vibrio parahaemolyticus [278] ( Table 1).…”

“…Infection of Atlantic salmon by A. salmonicida was observed to stimulate an acute-phase response (APR) as part of the innate immune defence system to infection, whose gene expression pattern was remarkably observed in liver at 7 days post-infection [275] indicating that the liver appears to be the main source of APPs in fish, as in mammals. Not surprisingly, the liver gene expression pattern observed in other fish species against L. anguillarum [276], E. tarda [277], and V. parahaemolyticus [278]. The APR is characterized by alterations in the levels of plasma proteins referred to as acute-phase proteins (APPs), as well as the secretion of some other innate defence molecules important for innate immunity, such as complementary systems [281][282][283].…”

Identification of three IFN-γ inducible lysosomal thiol reductase ( GILT )-like genes in mud crab Scylla paramamosain with distinct gene organizations and patterns of expression

“…The preparation of V. parahaemolyticus was as described previously (Bo et al, 2012). Mud crabs (150 ± 8 g in weight, with carapace length of 57 ± 5 mm) were acclimated for one week at 23-25°C in filtered, aerated seawater before injection with 200 μL live V. parahaemolyticus (7.5 × 10 5 CFU/mL) re-suspended in saline (0.8% NaCl), or saline as control.…”
