Single cell RNA-seq and VDJ-seq of B cells from sheep red blood cells-primed WT and Stch cKO mice
Once activated, B cells produce the antibodies needed to fight against infection. B cells are necessary for adaptive or specific immunity, which focuses on the destruction of foreign invaders that have gotten past the bodies initial defenses. Heat shock protein family is a group of highly conserved molecular chaperones with important functions in protein folding such as antibody and in signal transduction. Stch (Heat shock 70 kDa protein 13) is a member of the heat shock protein 70 family and is found associated with microsomes. Members of this protein family play a role in the processing of cytosolic and secretory proteins. To explore the role of Stch in B-cell activation and antibody production, we evaluated the transcriptional events and the role of stch pathway on the activation and antibody production of B cells by single cell RNAseq. Splenic lymphocytes were isolated from 7-9-week-old female Stchf/f wildtype (WT) mice and B-cell specific Stch knocked-out (CD19creStchf/f) mice (3 mice/group) using Ficoll (Ficoll-Paque Plus, GE Healthcre). B cells were sorted using B220 microbeads (Cat No. 130-049-501, Miltenyi Biotec, Germany). Their transcriptomes were captured using a 10x chromium system.
