Immune condition of the carpet shell clam (Ruditapes decussatus) haemocytes in response to temperature challenge
Graphical Abstract Abstract The aim of this study was to investigate the immunotoxic effects of acute temperature challenge in the carpet shell clam, Ruditapes decussatus . Haemolymph samples were incubated at 20 and 30 °C for 24 h. Total haemocyte count (THC), percentage of dead cells (PDC), phenoloxidase (PO), lysozyme (LYZ), alkaline phosphatase (ALP), esterase (EST), lectin (LCT), and antibacterial (AB) activities were chosen as biomarkers of temperature stress. Our results revealed that exposure to high temperatures increases the AB, and the LCT activities while it decreases the THC, the PDC, and the ALP activity. Meanwhile, no obvious negative effect of acute temperature stress was detected on PO, LYZ and EST
