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. …”

NPRL2 gene therapy induces effective antitumor immunity in KRAS/STK11 mutant anti-PD1 resistant metastatic non-small cell lung cancer (NSCLC) in a humanized mouse model by Ismail M Meraz, Mourad Majidi, Renduo Song, Feng Meng, Lihui Gao, Qi Wang, Jing Wang, Elizabeth J Shpall, Jack A Roth

“…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. …”
