Mouse used with mouse surrogate virus because human GM-CSF does not bind mouse receptor; human GM-CSF not bioactive in mice
“The expressed human GM-CSF is not bioactive in the mice, thus the findings are likely not related to exposure to this human protein.”

Surrogate molecule
Yes: mouse surrogate HSV-1 encoding murine GM-CSF (OncoVEXmGM-CSF) for pharmacology; clinical virus used in tox
“A mouse surrogate HSV-1 vector encoding the murine GM-CSF (OncoVEXmGM-CSF; JS1/34.5-/47-/mGM-CSF) was developed and used for the in vivo mouse studies because of the inability of human GM-CSF to bind to mouse GM-CSF receptor.”
