  • Exposure of quahogs to P. minimum resulted in: a lower percentage of phagocytic hemocytes, higher production of reactive oxygen species (ROS), larger hemocyte size, more-numerous hemocytic aggregates, and increased numbers of hemocytes in gills accompanied by vacuolation and hyperplasia of the water-tubular epithelial cells of the gills. (rwu.edu)

  • Flow cytometry analysis demonstrated that clodronate liposomes targeted large circulating hemocytes, resulting in a transient decrease in their number. (unimore.it)
  • Further, cellular defense status of clams was evaluated by analyzing hemocyte parameters (morphological and functional) using flow-cytometry. (rwu.edu)
  • The analyzed immune parameters were also compared with those measured in the clams kept at 4 °C for 12 h. (accesson.kr)
  • The immune parameters of the field-collected clams were 737,568/ml of THC, 0.553% of DNA damage, 41.962 A.U. of ROS, 0.121% of necrosis rate, and 0.055% of apoptosis rate, respectively. (accesson.kr)
  • This is consistent with reports indicating the large and agranular hemocyte population as the most represented among the professional phagocytes of P. canaliculata and with the hypothesis that different hemocyte morphologies could exert diverse biological functions, as it has been observed in other invertebrates.
