Immunosuppressive role of HMGB1 in TME
Immunosuppressive role of HMGB1 in TME
HMGB1 is a multifunctional protein with various roles in different cellular compartments. It exhibits a dual role in cancer cells; the intracellular HMGB1 acts as an anti-tumor protein stabilizing the genome, whereas the chronic released HMGB1 behaves as a pro-tumor protein with immunosuppressive functions.
In tumor microenvironment (TME), tumor cell-secreted HMGB1 inhibits the activities of T cells by inhibiting the maturation of dendritic cells (DCs) and promoting the activities of myeloid-derived suppressor cells (MDSCs) and Treg. HMGB1 also inhibits anti-tumor activity by binding to the immunosuppressive receptor TIM‐3. Moreover, HMGB1 interacts with RAGE and induces tumor cell migration, invasion and metastasis.
HMGB1 is a potential prognosis marker and a target for cancer therapy. arigo offers quality antibodies and ELISA kits to facilitate the research of the detailed mechanism underlying the immune suppression by HMGB1.
