Fig 7. CD4⁺CD8^- and CD4⁺CD8^+high phenotypes have biphasic and monophasic cytotoxicity kinetics against PRRSV-infected MDM, respectively.

The percentages of four T-cell phenotypes with PS⁺ death signals in the CTL assays using autologous (A) and heterologous (B) MDMs infected with PRRSV_SD23983 for 0 to 24 hours and then incubated for 1-hour with gilt-2 effectors are presented in graphs. The gating strategies for different T-cells are presented (C). Autologous and heterologous MHC-matched MDMs were prepared from PBMC of gilt-2 and gilt-678, respectively.
