Splet28. apr. 2014 · Rituximab causes a rapid depletion of CD20-expressing B-cell precursors and mature B-cells, which remain at very low or undetectable levels for 6–9 months before returning to pre-treatment levels. 7 Rituximab can lead to a state of immunosuppression through B-cell depletion, and also through the development of late onset neutropenia and … SpletIn humans, memory B cells are commonly identified by expression of CD27, coupled with low level expression of CD23/Fc epsilon RI, and lack of expression of the plasma cell marker, Syndecan-1/CD138. DEP-1/CD148 is also frequently used to identify human memory B cells, as are high level expression of B7-1/CD80, B7-2/CD86, and CD95.

Splet15. jan. 2003 · We have quantitated the response of naive and memory human B cells after in vitro stimulation with T cell-derived stimuli. In response to stimulation with CD40 ligand alone or with IL-10, both IgM-expressing and Ig isotype-switched memory B cells entered their first division 20–30 h earlier than did naive B cells. SpletFurthermore, both IgM and isotype switched memory B cells, but not naïve B cells, co-stimulated CD4+ T cells in vitro through a mechanism dependent on their constitutive expression of CD80 and CD86. This study demonstrates that upregulation of genes involved in activation, co-stimulation and survival provides memory B cells with a unique ...
