High Mobility Group Chromosal Protein N2 Is Expected to be as A Target of Cellular Immunetherapy in Leukemia and Tumors / 中国实验血液学杂志

ABSTRACT

Recently, chimeric antigen receptors T cells (CAR T) have made a breakthrough in the treatment of lymphoma and leukemia, open a new path for the tumor cellular immunetherapy. It is the key for CAR T to take the gene which can identify the CD19 antigen of lymphoblastic leukemia into lymphocytes, enable it to kill leukemia cells with specific cell-surface loci. The same principle also applies to other aspects, if we find specific target genes of lymphocytes. Recent studies have found that high mobility group protein N2 (high mobility group chromosal protein N2, HMGN2) is the excellent target of tumor-associated antigen in lymphocytes, is the antitumor effector molecule of CD8(+) T cells, which has the ability of trends and specific identify/binding in myeloid leukemia, breast cancer, cervical cancer and other tumor cells. HMGN2 is expected to be used for the preparation of specific identification of tumor lymphocytes and to treat more leukemia and tumors. This article focuses on the strucure and function of HMGN and the chemotaxis and antitumor effect of HMGN2 in leukemia and tumors.
