The immune cell specific genes detected were: 1) T-cell surface glycoprotein CD8 beta chain precursor (CD8b antigen) at 21 days PI; 2) Natural killer cell receptor 2B4 precursor (NK cell type I receptor protein 2B4; CD244 antigen) at 90 days PI; and 3) Natural killer-tumor recognition sequence isoform a. The gene discussed is CD244; the disease is neoplasm.
