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.

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.

Insect Biochemistry and Molecular Biology, 2005
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.

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.

Origin and Functions of Tunicate Hemocytes
2016Tunicates, or urochordates, are a subphylum of the phylum Chordata, sharing with other members of the phylum: (1) a permanent or temporary notochord, in the form of a dorsal rod; (2) a central nervous system, in the form of a dorsal tube; (3) a pharynx provided with gill slits or pharyngeal pouches, and a ventral gland secreting iodoproteins (endostyle

Cytophysiological features of hemocytes in cockroaches
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1972The wide range of functional activities of circulating and sessile insect hemocytes expresses itself in highly specialized cytological terms. Electron microscopic studies carried out in five species of normal and experimentally manipulated cockroaches, in conjunction with light microscopic information, reveal a broad spectrum of structural organization

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 ...

THE HEMOCYTES OF RHODNIUS PROLIXUS STÅL
The Biological Bulletin, 19651. The hemocytes of Rhodnius prolixus have been studied with phase contrast microscopy, after supravital staining, and in fixed and stained smears.2. With phase contrast microscopy, the following categories of circulating cells can be readily identified: (a) non-dividing and mitotically-dividing prohemocytes, (b) non-vacuolated and vacuolated ...

Lectin-binding to hemocytes of Mytilusedulis
Developmental & Comparative Immunology, 1985Lectin receptors for WGA, Ricinus 60, Ricinus 120, and for the agglutinin from the albumin gland of Helix pomatia were detected on the surface of Mytilus hemocytes by an agglutination assay. When hemocyte monolayers on slides were incubated with these lectins, strong rosette formation was obtained after addition of human erythrocytes. The lowest lectin
