Task: Answer Verification
Input (English): Question: Is early increased chemokine expression and production in murine allogeneic skin grafts mediated by natural killer cells?
Answer: Early chemokine mRNA expression and protein production in allogeneic skin grafts is amplified by recipient natural killer (NK) cells. These results indicate a novel function for infiltrating NK cells in mediating early increased intra-allograft chemokine production and inflammation during the initiation of acute rejection.
Output (English): yes
