cellular
decreased T cell proliferation ( J:159749 )
• decrease in the percentage of dividing CD8 T cells in response to stimulation by staphylococcal enterotoxin B pulsed A20 B cells or A20 B cells transfected with murine Pvr

hematopoietic system
decreased T cell proliferation ( J:159749 )
• decrease in the percentage of dividing CD8 T cells in response to stimulation by staphylococcal enterotoxin B pulsed A20 B cells or A20 B cells transfected with murine Pvr
impaired natural killer cell mediated cytotoxicity ( J:159749 )
• NK cells do not appreciably kill B16F10 tumor cells
• however, the ability to kill YAC-1 cells is unimpaired

immune system
decreased T cell proliferation ( J:159749 )
• decrease in the percentage of dividing CD8 T cells in response to stimulation by staphylococcal enterotoxin B pulsed A20 B cells or A20 B cells transfected with murine Pvr
impaired natural killer cell mediated cytotoxicity ( J:159749 )
• NK cells do not appreciably kill B16F10 tumor cells
• however, the ability to kill YAC-1 cells is unimpaired
decreased inflammatory response ( J:209990 )
• significantly increased survival rates after LPS-induced endotoxicosis at 0.5 or 0.75 mg LPS/30 g levels

neoplasm
increased metastatic potential ( J:159749 )
• with lower tumor doses mice have significantly higher numbers of B16F10 lung metastases than do wild-type
• the injection of the mouse prostate carcinoma, RM-1, at all tumor doses inoculated, results in significantly higher numbers of RM-1 lung metastases than in wild-type
increased tumor growth/size ( J:159749 )
• accelerated tumor growth is observed after subcutaneous injection of B16F10 compared to wild-type
• unlike wild-type mice, mice fail to reject the subcutaneous injection of a colon carcinoma cell line, MC38,that has been transfected with OVA
abnormal tumor susceptibility ( J:209990 )
• more lung metastases after injection of B16F10 melanoma cells into tail vein

hematopoietic system
decreased cytotoxic T cell cytolysis ( J:159749 )
• CD8 T cells kill B16 cells pulsed with OVA peptide 257-264 less effectively than control CD8 T cells
abnormal T cell activation ( J:159749 )
• CD8 T cells stimulated with T cell lymphoma cell line EL-4 transfected with Pvr and pulsed with OVA peptide 257-264 fail to become activated
decreased T cell proliferation ( J:159749 )
• in CD8 T cells stimulated with T cell lymphoma cell line EL-4 transfected with murine Pvr and pulsed with OVA peptide 257 ? 264
• however, proliferation in response to dendritic cell stimulation is similar to wild-type

decreased interferon-gamma secretion ( J:159749 )
• fewer IFN gamma secreting T cells are evident in lymph nodes after restimulation with the T cell lymphoma cell line EL-4 cells transfected with Pvr and pulsed with OVA peptide 257-264
• however, the frequency of IFN gamma secreting cells is similar to wild-type after restimulation with dendritic cells
