Prognostic significance of the heterogenous expression of IgG Fc receptors in B-cell chronic lymphocytic leukemia

Receptors for the Fc part of IgG (FcγR) are expressed in three forms on peripheral blood lymphocytes. The presence of the releasable form (FcγR_REL.) as well as of the two nonreleasable forms with lower (FcγR_LOW) ...

Unusual basement layer in the midgut of gammaridean Niphargus virei Chevreux (Crustacea, Amphipoda)

The basement membrane of the midgut and posterior caeca epithelium in the gammaridean amphipod Niphargus virei Chevreux, 1896 is made of an unusual structure. This basal lamina, properly called “basal layer”, sho...
