In vivo effects of LCO soluble fraction on immune-related functions and gene transcription in the Pacific oyster, Crassostrea gigas (Thunberg)
International audience The effects of a soluble fraction of light cycle oil (LCO) on haemocyte parameters, phenoloxidase (PO) activity and mRNA expression of immune-related genes, in the Pacific oyster, Crassostrea gigas, were tested after seven days of exposure and two weeks of recovery period.
