immune system
abnormal CD8-positive, alpha-beta T cell physiology ( J:141009 )
• cells produce less granzyme B than control cells after stimulation with allogeneic control dendritic cells (DCs) or DL1-DCs
abnormal cytotoxic T cell physiology ( J:141009 )
• mice, injected with spleen cells that were pulsed with OT-I (ova) peptide and 4 days later given labeled spleen cells or labeled spleen cells that were pulsed with OT-I (ova) peptide show little CTL-mediated killing of either population; in contrast, control mice display preferential cytolysis of OT-I pulsed spleen cells
increased susceptibility to parasitic infection ( J:141009 )
• mice display much earlier death after Trypanosoma cruzi infection compared to controls
