Human Gene Set: GSE15215_CD2_POS_VS_NEG_PDC_UP


Standard name GSE15215_CD2_POS_VS_NEG_PDC_UP
Systematic name M3519
Brief description Genes up-regulated in comparison of CD2+ plasmacytoid dendritic cells (DC) versus CD2- cells.
Full description or abstract Plasmacytoid dendritic cells (pDCs) are key regulators of anti-viral immunity. They rapidly secrete IFN-alpha and cross-present viral antigens thereby launching adaptive immunity. Here we show that activated human pDCs inhibit replication of cancer cells, and kill them in a contact dependent fashion. Expression of CD2 distinguishes two pDC subsets with distinct phenotype and function. Both subsets secrete IFN-alpha and express Granzyme B and TRAIL. CD2high pDCs uniquely express lysozyme and can be found in tonsils and in tumors. Both subsets launch recall T cell response. However, CD2high pDCs secrete higher levels of IL12 p40, express higher levels of co-stimulatory molecule CD80 and are more efficient in triggering proliferation of naïve allogeneic T cells. Thus, human blood pDCs are composed of subsets with specific phenotype and functions.

We need your help: Update on GSEA/MSigDB funding support

Last November we submitted a proposal to NCI's Information Technology for Cancer Research (ITCR) program for the continued funding of GSEA and MSigDB. Unfortunately, our proposal was not funded in this round, but we were encouraged to resubmit for the next one. This funding is critical for our continuing support and enhancement of the GSEA-MSigDB resource.

For our original submission many of you sent us emails of support, an important requirement for these grants. We now ask for your help again. We would greatly appreciate a short email message from you describing how the resource has been of value to your work and any concerns you may have about its continued availability.

Please send us your message of support to gsea-los@broadinstitute.org on or before Monday June 5, 2023.

Thanks in advance for your help and support.
The GSEA/MSigDB Team.
