| description | ► Hemocyte subsets in
Biomphalaria glabrata and
Biomphalaria straminea. ► The same types of hemocytes in two species of mollusks. ► There are five types of cells in the hemolymph of
B. glabrata and
B. straminea.
Biomphalaria glabrata and
Biomphalaria straminea have been identified as intermediate hosts for
Schistosoma mansoni. Several studies have found two cell types in the hemolymph of
B. glabrata (hyalinocytes and granulocytes). However, there are no studies describing the hemocytes of
B. straminea. With the aim of further describing the hemocyte subsets in
B. glabrata and
B. straminea, we conducted a detailed study using optical microscopy and transmission electron microscopy. Based on the morphological characteristics of the cells, we identified the same types of hemocytes in two species of molluscs, namely: blast-like cells, granulocytes, type I hyalinocytes, type II hyalinocytes and type III hyalinocytes. Blast-like cells had a spherical profile with a central nucleus filling almost the whole cell. Granulocytes were characterized by presenting variable numbers of granules. Type I hyalinocytes were the most abundant cell type and displayed various cytoplasmic projections. Type II and type III hyalinocytes had never previously been reported. They were few in number and were characterized by having an eccentric nucleus. From these results, it is concluded that there are five types of cells in the hemolymph of
B. glabrata and
B. straminea. Further studies are now needed to identify the role of these hemocytes in the immune response of these snails. |
