Project description:RNAseq of germinal center B cells with different Blimp-1-GFP reporter level. Sorted germinal center populations were defined by their expression of Blimp-1-GFP reporter and the cell surface marker CD138 before they were further split into dark zone or light zone / dark zone like or light zone like cells based on their expression of the surface marker CXCR4 and CD83. We used RNAseq to find genes differentially regulated in various Blimp-1-GFP expressing germinal center populations from the spleen at day 10 after intraperitoneal immunisation with sheep red blood cells.
Project description:RNAseq of germinal center B cells (B220+IgDlowCD95+GL7+) with different Blimp-1-GFP reporter level in the presence of TfH cells or 72 hr after their depletion. Sorted germinal center populations were defined by their expression of Blimp-1-GFP reporter and the cell surface marker CD138. Analysed mice were bone marrow chimeras generated with a bone marrow mixture from CD4-cre+ Rosa26-loxP-stp-loxP-DTR Blimp-1GFP/+ (10%) and Rag1-/- OTII (90%) mice. In these mice TfH cells can be depleted by the injection of human diphteria toxin (DT).
