Description
Endogenous oligodendrocyte progenitor cells (OPCs) are a promising target to improve functional recovery after spinal cord injury (SCI) by remyelinating denuded, and therefore vulnerable, axons. Demyelination is the result of a primary insult and secondary injury, leading to conduction blocks and long-term degeneration of the axons, which subsequently can lead to the loss of their neuron. In response to SCI, dormant OPCs can be activated and subsequently start to proliferate and differentiate into mature myelinating oligodendrocytes (OLs). Therefore, researchers strive to control OPC responses, and utilize small molecule screening approaches in order to identify mechanisms of OPC activation, proliferation, migration and differentiation. Overall design: DEG analysis of primary OPC and OL populations, 5 biological replicates per population

Description
The goal of this study was to identify the molecular characteristics and putative markers distinguishing IL-10eGFP+CD138hi and IL-10eGFP-CD138hi plasmocytes. To this end, IL-10eGFP B-green mice were challenged intravenously with Salmonella typhimurium (strain SL7207, 10e7 CFU), and IL-10eGFP+CD138hi as well as IL-10eGFP-CD138hi plasmocytes were isolated from the spleen on the next day. For this, single cell suspensions were prepared, cells were treated with Fc block (10 g/ml, anti-CD16/CD32, clone 2.4G2), and then stained with an antibody against CD138 conjugated to PE (1/400; from BD Pharmingen) followed by incubation with anti-PE microbeads (Miltenyi Biotech). CD138+ cells were then enriched on Automacs (Miltenyi Biotech) using the program possel_d2. Cells were then stained with anti-CD19-PerCP, anti-CD138-PE, and antibodies against CD11b, CD11c, and TCR conjugated to APC as a dump channel to exclude possible contaminants. DAPI was added to exclude dead cells. Live IL-10eGFP+CD138hi and IL-10eGFP-CD138hi cells were subsequently isolated on a cell sorter. The purity of the samples was always above 98%. This led to the identification of LAG-3 as a cell surface receptor specifically expressed on IL-10eGFP+CD138hi cells but not on IL-10eGFP-CD138hi cells.
