The IL-2 receptor in hemocytes of the sea mussel Mytilus galloprovincialis Lmk.
In the hemolymph of the sea mussel Mytilus galloprovincialis, two different cell types have been found. Rounded (RH) cells display a nucleus that is very large in relation to the cell size; spread (SH) cells have an expanded cytoplasm and multiple granules. We determined by flow cytometry that only the SH cell types express three interleukin-2 receptor (IL-2R) subunits. Mussel IL-2R alpha and IL-2R beta subunits display a molecular weight similar to those in vertebrates tissues, whereas mussel IL-2R gamma is smaller than that in vertebrates. Both lipopolysaccharide and IL-2 induce IL-2R alpha expression, and such induction depends on the concentration of both agonists.
