| Brief description | Genes positively correlated with T cell responses (expansion and contraction, not long term) in peripheral blood mononuclear cell in seniors (50-75) after exposure to Zostavax , time point 1D. Comment: (A) Network of genes for which the change in expression correlated with both expansion and contraction and therefore not with long-term outcome |
| Full description or abstract | Vaccination with attenuated live varicella zoster virus (VZV) can prevent zoster reactivation, but protection is incomplete especially in an older population. To decipher the molecular mechanisms underlying variable vaccine responses, T- and B-cell responses to VZV vaccination were examined in individuals of different ages including identical twin pairs. Contrary to the induction of VZV-specific antibodies, antigen-specific T cell responses were significantly influenced by inherited factors. Diminished generation of long-lived memory T cells in older individuals was mainly caused by increased T cell loss after the peak response while the expansion of antigen-specific T cells was not affected by age. Gene expression in activated CD4 T cells at the time of the peak response identified gene modules related to cell cycle regulation and DNA repair that correlated with the contraction phase of the T cell response and consequently the generation of long-lived memory cells. These data identify cell cycle regulatory mechanisms as targets to reduce T cell attrition in a vaccine response and to improve the generation of antigen-specific T cell memory, in particular in an older population. |

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.
