项目摘要

Project 3: Role of Cellular Senescence in long-lived plasma cell generation Abstract: Human long-lived plasma cells (LLPC) are important in the maintenance of protective serum antibodies. The mechanisms of how LLPC are generated and sustained are not well elucidated. These bone marrow resident cells are terminally differentiated, nondividing, and refractory to apoptosis yet they are capable of secreting antibodies for a lifetime. Exodus from cell cycle and resistance to apoptosis are major hallmarks of cellular senescence. In this application, we will understand the role of cellular senescence in LLPC maturation transcriptionally and epigenetically through single cell analysis. We will also dissect the unique senescence pathways that are needed for survival; then finally we will identify the unique components of the BM microniche that plays a role in survival and senescence.

项目3：细胞衰老在长寿命的浆细胞产生中的作用抽象的：人类长期浆细胞（LLPC）在维持保护血清中很重要抗体。 LLPC的产生和持续方式的机制无法很好地阐明。这些骨髓驻留细胞是终极分化的，非分明的，并且难治性凋亡却能够在一生中分泌抗体。细胞周期的出埃及记对凋亡的抗性是细胞衰老的主要标志。在此应用程序中，我们将了解细胞衰老在LLPC成熟的转录和表观上的作用通过单细胞分析。我们还将剖析独特的衰老途径生存所需；最后，我们将确定BM Microniche的独特组成部分在生存和衰老中起作用。
