Recent Findings from Osaka University Has Provided New Information about Immunotherapy

May 26, 2014

By a News Reporter-Staff News Editor at Cancer Vaccine Week -- Research findings on Biotechnology are discussed in a new report. According to news reporting originating from Osaka, Japan, by NewsRx correspondents, research stated, "FOXP3(+)CD25(+)CD4(+) regulatory T (Treg) cells, crucial for the maintenance of immunological self-tolerance, are abundant in tumors. Most of them are chemo-attracted to tumor tissues, expanding locally and differentiating into a Treg-cell subpopulation that strongly suppresses the activation and expansion of tumor-antigen-specific effector T cells."

Our news editors obtained a quote from the research from Osaka University, "Several cancer immunotherapies targeting FOXP3(+)CD4(+) Treg cells, including depletion of Treg cells, are currently being tested in the clinic. In addition, clinical benefit of immune-checkpoint blockade, such as anti-CTLA-4 monoclonal antibody therapy, could be attributed at least in part to depletion of FOXP3(+)CD4(+) Treg cells from tumor tissues."

According to the news editors, the research concluded: "Thus, optimal strategies need to be established for reducing Treg cells or attenuating their suppressive activity in tumor tissues, together with activating and expanding tumor-specific effector T cells."
