Integument and hemocyte peptides
Journal of Insect Physiology, 1994Abstract There are four routing classes of integument peptide in the caterpillar of Calpodes ethlius. The epidermis secretes peptides apically into the cuticle (C), basally into the hemolymph (H) and in both directions (BD). Peptides in a 4th class (T), are presumed to be transported across the epidermis, because the epidermis does not synthesize ...

Different roles of crayfish hemocytes in the uptake of foreign particles
Fish and Shellfish Immunology, 2018Crustacean hemocytes are known to remove invading pathogens by phagocytosis. In this study, we investigated how the semigranular cells (SGCs) and granular cells (GCs) of crayfish Cherax quadricarinatus participated in this process.

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.

Shrimp, as invertebrates, have an open vasculature that allows circulating hemocytes to infiltrate the tissues, where they are referred to as sessile hemocytes.

1979
The function of insect blood cells has long puzzled scientists. This much-needed volume, first published in 1979, attempts to explain the forms and functions of insect hemocytes, creating a solid basis from which work in the field may proceed. Insect Hemocytes had its origins in a symposium held at the XV International Congress of Entomology (1976). It

Presumed hemocytic neoplasms in scorpions
Veterinary PathologyAlthough neoplasia has been documented in invertebrates, it has not been reported in scorpions. This report describes presumed hemocytic neoplasia in 2 scorpions: a >3-year-old, female emperor scorpion ( Pandinus imperator) and a >4-year-old, male, Asian forest scorpion ( Heterometrus sp.). The emperor scorpion had a 1-month history of body wall

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 ...

Immunomodulation by 17β-estradiol in bivalve hemocytes
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2006In mammals, estrogens have dose- and cell-type-specific effects on immune cells and may act as pro- and anti-inflammatory stimuli, depending on the setting. In the bivalve mollusc Mytilus, the natural estrogen 17β-estradiol (E2) has been shown to affect neuroimmune functions.

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.

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.
