Project description:Understanding pathogen recognition and mechanisms in Atlantic cod are of significant importance for both basic research on wild populations and health management in aquaculture. A microarray approach was utilized to search for effects of viral (poly I:C/ polyinosinic acid:polycytidylic acid), bacterial (LPS/lipopolysaccharide) and polyclonal activator (PHA-L/phytohaemoagglutinin) stress in Atlantic cod head kidney cells. LPS cell activation increased mRNA expression of chemokine/Interleukin 8 (CXCL8/IL-8); interleukin -1? (IL-1?); cyclooxygenase 2 (COX2); leukocyte derived chemotaxin 2 (LECT2); LOC100698154, encoding a protein with unknown function; carboxyl-esterase 2 (CES2) and environmental biomarker cytochrome P450 1A (CYP1A). Mitogen activated protein kinase p38 (p38MAPK) and cathepsin F (CTSF) were downregulated by LPS. The antiviral responses induced by double stranded RNA (Poly I:C) clearly increased transcription of Toll like receptor 3 (TLR3) and interferon stimulating gene 15 (ISG15). The PHA response seemed to be more non-specific. Special for the PHA induction were the increase in Major histocompatibility complex class I (MHCI). CC chemokine type 2 (CK2) mRNA expression was increased by PHA, LPS and poly I:C, while p38MAPK and LECT2 was downregulated by PHA. Oxidative stress related genes like catalase and glutaredoxin (GLRX2) and the anti-apoptotic gene Bcl-2 showed no transcriptional changes compared to control in any of the treatments. Especially Poly I:C, but also LPS, induced leukotriene B4 (LTB4) and leukotriene B5 (LTB5) synthesis, while small amounts of prostaglandine E2 (PGE2) seemed to be constitutively produced in untreated cells, a production that was slightly elevated when exposing cells for LPS. This study reveals distinct signatures of bacteria and virus transcriptional responses in cod head kidney cells. In addition, the novel finding that Cyp1a was upregulated during the antibacterial response indicates a connection between immunity and aryl hydrocarbon receptor (AhR) activation in Atlantic cod.
