  • SE-induced MAPK activation within these neurons was repressed by STEP, leading to cell death. (jneurosci.org)
  • NK cell activation and the triggering of effector functions is governed by a complex set of activating and inhibitory receptors. (frontiersin.org)
  • Nascent transformed cells elicit NK cell activation and are eliminated. (frontiersin.org)
  • Findings also showed that in patients treated with DC1 at 100 x 106 cells, there was a decrease in peripherally circulating anti-HER2 T-cell response at week 6, which study authors attributed to a likely increase in T-cell trafficking to the tumor site. (onclive.com)
  • These findings identify a key set of signaling events that render somatostatinergic hilar interneurons vulnerable to SE-induced cell death. (jneurosci.org)

  • Drug interaction was studied using the combination index method, while cell cycle was investigated with flow cytometry. (worktribe.com)
  • A stable frequency of S-specific CD8 T cells was noted in circulation, and the CD38 levels decreased with budesonide therapy. (alecomm.com)
  • Unlike CAR T-cell therapy or TCR therapy, which modifies T cells taken from the blood, TIL therapy utilizes T cells that have infiltrated the tumor stroma, which requires a tumor biopsy. (aacr.org)
  • Background The capacity of cytomegalovirus (CMV) to elicit long-lasting strong T cell responses, and the ability to engineer the genome of this DNA virus positions CMV-based vaccine vectors highly suitable as a cancer vaccine platform. (bmj.com)
