A C-type lectin with an immunoglobulin-like domain promotes phagocytosis of hemocytes in crayfish Procambarus clarkii

Scientific Reports, 2016
C-type lectins are important immune molecules that participate in host defense response. The present work reports a novel C-type lectin (PcLec3) from the red swamp crayfish Procambarus clarkii.

Ultrastructural and Cytotoxic Effects of Metarhizium robertsii Infection on Rhipicephalus microplus Hemocytes

Frontiers in Physiology, 2019
Metarhizium is an entomopathogenic fungus widely employed in the biological control of arthropods. Hemocytes present in the hemolymph of invertebrates are the cells involved in the immune response of arthropods.

Molecular Profiling of Phagocytic Immune Cells in Anopheles gambiae Reveals Integral Roles for Hemocytes in Mosquito Innate Immunity*

Molecular & Cellular Proteomics, 2016
The innate immune response is highly conserved across all eukaryotes and has been studied in great detail in several model organisms. Hemocytes, the primary immune cell population in mosquitoes, are important components of the mosquito innate immune ...

Active Hematopoietic Hubs in Drosophila Adults Generate Hemocytes and Contribute to Immune Response

Developmental Cell, 2015
Summary Blood cell development in Drosophila shares significant similarities with vertebrate. The conservation ranges from biphasic mode of hematopoiesis to signaling molecules crucial for progenitor cell formation, maintenance, and differentiation ...

EM Study of Isopod Hemocytes

Microscopy and Microanalysis, 1998
Abstract Crustacean hemocytes have been characterized on the basis of cell size and nature of cytoplasmic granules. Based on light microscopic morphological analysis and cytochemistry, investigators variously named the hemocyte types (agranular, small-granule, large granule, undifferentiated, hyaline cells, non-explosive, explosive ...

Hemocytes control stem cell activity in the Drosophila intestine

Nature Cell Biology, 2015
Coordination of stem cell activity with inflammatory responses is critical for regeneration and homeostasis of barrier epithelia. The temporal sequence of cell interactions during injury-induced regeneration is only beginning to be understood.

A Drosophila Model to Image Phagosome Maturation

Cells, 2013
Phagocytosis involves the internalization of extracellular material by invagination of the plasma membrane to form intracellular vesicles called phagosomes, which have functions that include pathogen degradation.

Immune Defenses of the Invasive Apple Snail Pomacea canaliculata (Caenogastropoda, Ampullariidae): Phagocytic Hemocytes in the Circulation and the Kidney

PLoS ONE, 2015
Hemocytes in the circulation and kidney islets, as well as their phagocytic responses to microorganisms and fluorescent beads, have been studied in Pomacea canaliculata, using flow cytometry, light microscopy (including confocal laser scanning microscopy)
