Splenic CD8+ and CD8- DCs


ABSTRACT: Analysis of gene expressions in mouse splenic dendritic cells (DCs). DCs were purified into two subsets, CD8-positive and -negative ones. DCs were expanded in vivo by injecting Flt3L-producing tumors into the backs of C57BL/6 mice. To expand DCs in vivo, Flt3L-producing B16 melanoma cells were injected to the backs of mice. Then, 10-12 days later, splenic DCs were enriched by MACS and purified into CD3-B220-CD8a+CD11c+ and CD3-B220-CD8a-CD11c+ cells by FACS cell sorter.

A new triggering receptor expressed on myeloid cells (Trem) family member, Trem-like 4, binds to dead cells and is a DNAX activation protein 12-linked marker for subsets of mouse macrophages and dendritic cells.

Dendritic cells (DCs) are professional APCs that can control immune responses against self and altered self, typically foreign, determinants. DCs can be divided into several subsets, including CD8alpha(+) and CD8alpha(-) DCs. These subsets possess specific functions. For example, mouse splenic CD8alpha(+), but not CD8alpha(-) DCs selectively take up dying cells and cross-present cell-associated Ags to naive T cells. In this study, we identified genes that were more expressed in CD8alpha(+) than  ...[more]
