WebHemolymph, or haemolymph, is a fluid, analogous to the blood in vertebrates, that circulates in the interior of the arthropod (invertebrate) body, remaining in direct contact with the animal's tissues. It is composed of a fluid plasma in which hemolymph cells called hemocytes are suspended. Web16 sep. 2005 · Most proteins in insect hemolymph, the insect equivalent of blood serum, are produced in fat body cells, which also secrete antimicrobial peptides that constitute an important component of the humoral immune defense ( 7 ).

WebHemocytes are further treated with different endocytic inhibitors, methyl-β-cyclodextrin (MβCD) and chlorpromazine (CPZ). WSSV still can be detected in the hemocytes treated with CPZ, but not in the hemocytes treated with MβCD. Thus, we conclude that WSSV adopts the caveolae-mediated endocytosis to enter the shrimp cell. 收回 WebInsect hemocytin generally consists of 3 000-4 000 amino acids with multiple and repeatedly arranged domains including FA58C (coagulation factor 5 or 8 C-terminal), VWD (von Willebrand factor type D), ...
