Project description:Chimeric antigen receptor (CAR) engineering of NK cells is an active area of research with early-phase clinical studies showing an excellent safety profile with encouraging clinical responses. However, the transcriptional signatures that control the fate of CAR-NK cell after infusion and their association with tumor control remain poorly understood. Here, we performed single-cell RNA sequencing (scRNA-seq) to depict the evolution of various engineered CAR-NK cells Single cell RNA sequencing (scRNA) has revolutionized high-thoughout systems-based analysis of cellular and functional heterogeneity, The goals of this work are to compare transcriptome profiling (RNA-seq).
Project description:The mitogen activated kinases ERK1/2 are activated by antigen receptor engagement and control T cell differentiation. We have used mass spectrometry to explore how ERK1/2 control antigen receptor driven cell growth and proteome restructuring in CD8 T cells. Quantitative analysis of >8000 proteins provides new understanding of the highly selective role of ERK1/2 in controlling T cell protein systems. The data reveal that ERK signalling is not a dominant regulator of the metabolic and biosynthetic programs that drive T cell growth. Rather, the dominant function of ERK1/2 is to control the repertoire of transcription factors, cytokines and cytokine receptors expressed by activated T cells. This study provides a comprehensive map of how T cell phenotypes are selectively shaped by ERK1/2 and reveals that ERK1/2 controls the transcriptional reprogramming of activated T cells that is pivotal for T cell differentiation and acquisition of effector function.
Project description:RNA sequencing was used to characterise PGE2-mediated changes in the gene expression profile of in vitro differentiated and repetitively activated antigen-experienced TCF1+CD8+ T cells.
Project description:We used microarrays to detail the gene expression profile during WAT -beige transition by treatment of beta adrenergic receptor agonist .
Project description:Upon immunization with a T cell dependent antigen naive follicular B cells (Fo) are activated and a germinal center reaction is induced. Within the next 2 weeks large germinal centers develop where the process of affinity maturation takes place. To analyze the gene expression profile of resting and activated B cells, follicular B cells (Fo), B cells from early (GC1) and late germinal centers (GC2) were isolated and their gene expression profile compared.
