Gene expression profile at single cell level of plasma cells (PCs) from human bone marrow

ABSTRACT: Antibody-secreting plasma cells (PCs) are generated in secondary lymphoid organs, but are reported to reside in an emerging range of anatomical sites. Analysis of the transcriptome of different tissue-resident (Tr)PC populations revealed that they each have their own transcriptional signature indicative of functional adaptation to the host tissue environment. In contrast to expectation, all TrPCs were extremely long-lived, regardless of their organ of residence, with the longevity influenced by intrinsic factors like the immunoglobulin isotype. Analysis at single-cell resolution revealed that the bone marrow is unique in housing a compendium of PCs generated all over the body that retain aspects of the transcriptional program indicative of their tissue of origin.

Unraveling the diversity and functions of tissue-resident plasma cells (RNA-seq of mouse antibody-secreting cells)

Project description:Antibody-secreting plasma cells (PCs) are generated in secondary lymphoid organs, but are reported to reside in an emerging range of anatomical sites. Analysis of the transcriptome of different tissue-resident (Tr)PC populations revealed that they each have their own transcriptional signature indicative of functional adaptation to the host tissue environment. In contrast to expectation, all TrPCs were extremely long-lived, regardless of their organ of residence, with the longevity influenced by intrinsic factors like the immunoglobulin isotype. This study reveals that extreme longevity is an intrinsic property of TrPCs whose transcriptome is imprinted by signals received both at the site of induction and within the tissue of residence.

Microarray analysis of regenerating parietal cells (PCs) in murine gastric epithelium recovering from Diphtheria toxin injury

Project description:Highly specialized, acid-secreting PCs are one of many epithelial lineages that line the gastric epithelium. Even though PCs are functionally and structurally distinct from other lineages in the stomach, the molecular mechanisms that govern their specification and maturation from the gastric stem cells are relatively unknown. We used microarray analysis to interrogate transcriptional changes that occur in regenerating PCs and to identify candidate regulators of PC fate specification and maturation.

Single cell transcriptional analysis of regenerating parietal cells (PCs) in murine gastric epithelium recovering from Diphtheria toxin injury

Project description:Highly specialized, acid-secreting PCs are one of many epithelial lineages that line the gastric epithelium. Even though PCs are functionally and structurally distinct from other lineages in the stomach, the molecular mechanisms that govern their specification and maturation from the gastric stem cells are relatively unknown. We used single cell RNA sequencing (scRNA-seq) to construct a transcriptional profile for regenerating PCs and identify candidate regulators of PC fate specification and maturation.

Absolute quantification of budding yeast proteome with PCS method

Project description:Absolute quantification of proteome is one of the most important tasks in proteomic research. The aim in this analysis is providing proof-of-principle of our originally developed strategy for absolute quantification of multiple proteins present at various concentrations in a cell, using stable isotope-labeled peptide concatenated standard (PCS). This study also provides insights into structures of regulation of metabolic pathway and into biological mechanisms for regulation of expressed protein abundance.
