Mice that received transplants of syngeneic FasL⁺ lin⁻ BMs responded to an antigenic infectious challenge.

(A) Representative liver histologies of mice 4 days afterL monocytogenes injection. Some hepatic inflammation was seen in all mice in both control (top) and experimental (bottom) groups. (B) Livers were analyzed for T-cell infiltration by making single-cell suspensions from a portion of the liver and staining for T-cell markers. Shown are representative FACS plots of correlated CD4 and CD8 staining of the liver cells from a normal uninfected mouse liver, a liver from a mouse that received a transplant of control GFP⁺ lin⁻ BMs, and a liver from a mouse that received a transplant of FasL⁺ lin⁻BMs.
