“…In P. leniusculus, Söderhäll et al (1986) revealed that both hyaline and semigranular cells function as agents of phagocytosis. Since the granular features of GI and GII of the present study resemble those reported for other crustaceans (Hose et al, 1990;Vázquez et al, 1997;Hong da, 2002;Laxmilatha and Laxminarayana, 2004;Vargas-Albores et al, 2005;Nisha, 2006;Sanguanrut et al, 2010) it is possible that these cells also execute similar roles in T. schirnerae. Further cytochemical investigations are required to ascertain their definite roles in the immune processes of T. schirnerae.…”

“…The Ag of T. schirnerae, generally devoid of granules, was comparable to the hyaline cells reported for other crustaceans (Hose et al, 1990;Vázquez et al, 1997;Vargas-Albores et al, 2005). Granules were rare in the hyaline cells of E. sinensis (Bauchau and De Brouwer, 1972) and Scylla olivacea (Sa-nguanrut et al, 2010) and in hyalinocytes of F. indicus (Laxmilatha and Laxminarayana, 2004).…”

The light and ultrastructural observations on haemocyte profile of the freshwater crab Travancoriana schirnerae demonstrated three cell types: agranulocyte, granulocyte I and granulocyte II. Agranulocytes are the smallest of the haemocyte types, comprised 38% of the haemocytes, devoid of granules and showed high nucleoprotoplasmic ratio. Their cytoplasm contained numerous free ribosomes, vesicles of smooth endoplasmic reticulum, few mitochondria with parallel cristae and vacuoles. Granulocytes I (37%) are the largest of the haemocyte types, characterized by the presence of numerous granules (26 to 61) of varying size, shape and densities and organelles like mitochondria, free ribosomes and peripheral vacuoles and displayed low nucleoprotoplasmic ratio. Granulocytes II (25%) contained large electron dense granules (10 to 23) and organelles like free ribosomes and vacuoles and showed intermediate nucleoprotoplasmic ratio. Unlike granulocytes, agranulocytes exhibited prominent pseudopodial projections suggesting a phagocytory function. This study revealed the unusual occurrence of a binucleate agranulocyte and a rare phenomenon called clasmatosis of granulocyte II, wherein part of the cell fragments off along with cytoplasmic contents devoid of nucleus.

“…Phagocytosis by various cell types of M. rosenbergii has earlier been examined and contradictory findings have been described. For example, Sung et al [8] found that hyaline cells were the primary phagocytes for elimination of bacteria, whereas large granular haemocytes were found to be the only cell phagocytic towards chicken erythrocytes in M. rosenbergii [35]. In another study, large ovoid and rounded haemocytes were reported to exert phagocytic activity in M. rosenbergii [20].…”

“…For example, small and large GCs have been demonstrated to be phagocytotic in H. americanus, P. interruptus and Loxorhynchus grandis (Hose et al, 1990), whereas HCs in Carcinus maenas have been demonstrated to be phagocytotic after coating bacteria with peroxinectin, indicating cell-to-cell cooperation (Smith and Ratcliffe, 1980;Thörnqvist et al, 1994). In, contrast, GCs were found to be phagocytotic in shrimp (Gargioni and Barracco, 1998;Vázquez et al, 1997).…”

Crustacean hemocytes are important mediators of immune reactions, and the regulation of hemocyte homeostasis is of utmost importance for the health of these animals. This review discusses the current knowledge on the lineages, synthesis and differentiation of hemocytes in crustaceans. Hematopoietic tissues, their origins, and the regulation of hematopoiesis during molting, seasonal variation and infection are discussed. Furthermore, studies concerning the molecular regulation of hemocyte formation in crustaceans are also described, and the different lineages and their molecular markers are discussed and compared with several insect species. Signaling pathways and the regulation of hematopoiesis by transcription factors are typically conserved among these arthropods, whereas cytokines and growth factors are more variable and species specific. However, considering the great diversity among the crustaceans, one should be cautious in drawing general conclusions from studies of only a few species.2
