Fig. 6. Crassostrea gigas (mollusc). (A) Response of oyster haemocytes incubated in 2E,4E-decadienal or decanal (at concentrations of 2 and 50 µmol l^-1) and DMSO (solvent control). Values (mean ± S.E.M.) are given for three replicate tests, showing the proportions of blood cells presenting phagocytosis inhibition with each treatment. (B) Fluorescent confocal micrographs of three consecutive optical sections of normal (1) and inhibited (2) haemocytes, related to presence (P) or absence of fluorescent phagocytosed beads observed inside the cytoplasm. N, cell nucleus.
