Project description:The CD19 positive antibody secreting cells (ASC) in both bone marrow (BM) have the capacity to provide immune memory in addition to cells traditionally considered long-lived, the CD19-negative BM ASC. We performed flow cytometry (FCM) immunophenotyping, fluorescence-activated cell sorting (FACS) for cell subset isolation, ELISpot assays detecting the isotype of antibody secretion as well as antibodies against vaccine derived antigens, and comparative gene expression analyses of CD19- ASC, CD19+ ASC, CD20- B cells, and CD20+ B cells from BM. The findings may aid in the understanding of the differential cell subsets created through vaccination and lead to improved vaccine strategies and production. FACS sorted tissue B cells and antibody secreting cell subset gene expression.
Project description:We measured genes expression differences in antibody secreting cells from LynKO mice in following treatment with a BMI-1 inhibitor (PTC-028) or a vehicle control. BMI-1 inhibition lead to a reduction in antibody secreting cells in LynKO mice and in humans donors. We performed RNA sequencing to understand the impact of BMI-1 inhibition on antibody secreting cells in LynKO mice.
Project description:We report whole transcriptome RNASeq data for cell-sorted pop2, pop3, and pop5 which are antibody-secreting cells from human peripheral blood
