When the tumor infiltrating cells from 30-week-old K-rasG12D mice were studied by flow cytometry, a slight increase in the percentage of CD4+ T and NK cells that expressed the CD69 activation marker, and a slight increase in the γδ T cells was found in m and hROS1 electrovaccinated mice, compared to controls (Figure S4b). The gene discussed is CD4; the disease is neoplasm.
