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.

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

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

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 ...

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

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

Cytotoxic Activity of Tunicate Hemocytes
1996Tunicates (protochordates) are filter-feeding marine invertebrates with a worldwide distribution. In their larval form, they exhibit many of the features characteristic of the vertebrates. The larva, with a tail, notochord, and dorsal neural tube, upon settlement undergoes a remarkable metamorphosis in which it loses most of its chordate ...

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.).

ENTOMON, 2020
The plasmocytes in five different scorpions- Mesobuthus tumulus tamulus, M. tumulus concanesis, Orthochirus bicolor, Heterometrus xanthopus, H. phipsoni were studied in the present investigation. The hemocytes are polymorphic and their population is about 70 – 80%. The length varied from 6- 12 μm and the width is 6- 12 μm in M.
