Cd28tm1Mak mutation (12 available); any Cd28 mutation (53 available)
Tg(TcrLCMV)327Sdz mutation (8 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
immune system
• CD8 T cells require 10- to 100-fold more antigen (gp33 peptide) to induce the same amount of proliferation as cells from Tg(TcrLCMV)327Sdz mice
• however, addition of IL2 restores CD8 T cell proliferation in response to gp33 peptide
• in mice treated gp33 peptide
• after 3 days, cytotoxic T lymphocyte (CTL) activation in mice treated with gp33 peptide is decreased compared to in Tg(TcrLCMV)327Sdz mice
• splenocytes exposed to gp33 exhibit impaired CTL activation compared with similarly treated cells from Tg(TcrLCMV)327Sdz mice
• however, CTL activation in mice treated with gp33 peptide is normal at day 1 and treatment with IL2 restores CTL in splenocytes
• cytotoxic T lymphocyte anergy in mice treated with gp33 peptide is induced unlike in similarly treated Tg(TcrLCMV)327Sdz mice
