Hemocyte lysate enhancement of fungal spore encapsulation by crayfish hemocytes
Developmental & Comparative Immunology, 1984Crayfish hemocytes exhibited a stronger encapsulation reaction to fungal blastospores of Beauveria bassiana coated with hemocyte lysate, than to blastospores treated with plasma or buffer, indicating an opsonic function of hemocyte lysate proteins.

Cadmium turnover in the hemocytes of Mercenaria mercenaria (L.) in relation to hemocyte turnover
Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1999The turnover of cadmium (Cd) in the hemocytes of the quahog Mercenaria mercenaria L. was investigated using 109Cd radiolabeling, and compared to the rate of hemocyte turnover as estimated following [3H]thymidine incorporation. Quahogs were injected with 5 microl of 0.8 microM 109Cd, and the hemocytes sampled over a 60-day depuration period.

In insects, melanotic encapsulation is an important innate immune response against large pathogens or parasites, and phenoloxidase (PO) is a key enzyme in this process. Activation of prophenoloxidase (proPO) to PO is mediated by a serine proteinase cascade. PO has a tendency to adhere to foreign surfaces including hemocyte surfaces.

Hemocytes and hemocytic responses in the mole crab Emerita emeritus (Linnaeus 1767)
Journal of Invertebrate Pathology, 2017The mole crab, Emerita emeritus, collected from the sandy shores of a Chennai beach, was investigated for cellular immune responses based on the morphology and defensive reactions of the circulating haemocytes. Three haemocyte morphotypes were identified using light and electron microscopy, and separated in a discontinuous percoll gradient.

Hemocytes and hemocytopoiesis in Silkworms
Biochimie, 1979A brief review is presented of the current state of ultrastructure, cytochemistry, and physiology of the hemocytes and meso- and metathoracic peri-imaginal-wing organs in silkworms. According to the accepted morphological classification, five circulating types of hemocytes are recognized in Bombyx mori as well as in Antheraea pernyi.

Insect hemocytes and their role in immunity
Insect Biochemistry and Molecular Biology, 2002The innate immune system of insects is divided into humoral and cellular defense responses. Humoral defenses include antimicrobial peptides, the cascades that regulate coagulation and melanization of hemolymph, and the production of reactive intermediates of oxygen and nitrogen.

Hemocytes of the cochineal insect: ultrastructure
Archives of Insect Biochemistry and Physiology, 2010AbstractUsing transmission electron microscopy, light microscopy (Giemsa May‐Grumwald), and the Periodic Acid‐Schif (PAS) and Sudan Black B staining techniques, hemocytes in the hemolymph of adult female Dactylopius coccus were characterized. The following, in order of abundance, were found: granulocytes, plasmatocytes, prohemocytes, and oenocytoids ...

Activation of lobster hemocytes for phagocytosis
Journal of Invertebrate Pathology, 1984Abstract Activation of lobster (Homarus americanus) hemocytes for phagocytosis of sheep erythrocytes (SRBC) was demonstrated in vitro by incubation with lipopolysaccharide and by prolonged adherence to glass coverslips. Morphological changes, which preceded phagocytic activation, were detected by phase microscopy and Nomarski interference microscopy.

Upon encountering an object recognized as foreign, insect hemocytes aggregate in multiple layers on the surfaces of the object in a process known as encapsulation. For encapsulation to occur, hemocytes must switch from their usual nonadherent state to an adherent state, presumably by regulating the activity of adhesion proteins.
