Marginal zone B cells regulate antigen-specific T cell responses during infection.

Marginal zone B cells (MZB) participate in the early immune response to several pathogens. In this study, we show that in μMT mice infected with Leishmania donovani, CD8 T cells displayed a greater cytotoxic potential and generated more effector memory cells compared with infected wild type mice. The frequency of parasite-specific, IFN-γ(+) CD4 T cells was also increased in μMT mice. B cells we...

Marginal Zone B-cell lymphoma

Extra-nodal MZBCL of MALT type (7% of all NHL) is an indolent disease involving most often the stomach, where it usually follows chronic gastritis due to Helicobacter pylori (HP) infection. The disease may also localize in the lung, the thyroid, the salivary gland, the orbit. Splenic MZBCL (1% of all NHL on histologic samples) usually, though not invariably, presents splenomegaly associated cir...
