Combination of potassium oxonate with anti-PD-1 for the treatment of colorectal cancer by Yuanyuan Wang, Chenxi Hu, Tianpeng Du, Jiawen Li, Kaiyuan Hui, Xiaodong Jiang

“…The TME were tended to an environment beneficial for killing tumors by enhancing chemotactic factor release, increasing CD8+ T cell infiltration and activation, and decreasing the amount of regulatory T cells. Moreover, IFN-γ and IL-2 secretion were found to be enriched in the tumor TME.ConclusionOur study indicated that combination of PO and anti-PD-1 could synergistically suppress CRC progression and altered the tumor microenvironment in favor of antitumor immune responses.…”

Bone marrow immune cells and drug resistance in acute myeloid leukemia by Miao Zhang, Miao Zhang, You Yang, You Yang, Jing Liu, Jing Liu, Ling Guo, Ling Guo, Qulian Guo, Qulian Guo, Wenjun Liu, Wenjun Liu

“…The abnormal number and function of immunosuppressive cells, including regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs), along with the dysfunction and exhaustion of immunological effector cells, including cytotoxic T lymphocytes (CTLs), dendritic cells (DCs) and natural killer cells (NKs), can induce immune escape of leukemia cells and are closely linked to therapy resistance in leukemia. …”

Escherichia coli combination with PD-1 blockade synergistically enhances immunotherapy in glioblastoma multiforme by regulating the immune cells by Guochen Li, Haiyan Yang, Tengfei Ke, Na Tan, Xiaolan Du, Xirui Duan, Xinyan Zhou, Guangrong Zheng, Chengde Liao

“…Immunofluorescence staining and flow cytometry results demonstrated that the combination treatment group exhibited a significant upregulation of cytotoxic CD8+ T cells and a marked suppression of regulatory T cells compared to the control group. The expression of Ki67 was significantly downregulated, and TUNEL staining revealed an increased number of apoptotic cells in the combination treatment group. …”

“…The antitumor effect was correlated with increased infiltration of human cytotoxic-T, HLA-DR+DC, CD11c+DC, and downregulation of myeloid and regulatory-T cells in TME. Antitumor effect was abolished upon in-vivo depletion of CD8-T, macrophages, and CD4-T cells whereas remained unaffected upon NK-cell depletion. …”
