Thus, to specifically determine if Gr1−/lowCD11b−/low myeloid cells could cross‐present Ag to provoke a T cell response, we sorted splenic Gr1−/lowCD11b−/low myeloid cells and pulsed them with recombinant Neu ECD protein, followed by a culturing period with tumor‐sensitized T cells. The gene discussed is ERBB2; the disease is neoplasm.
