Project description:Investigating the tumor immune microenvironment and tumor cell proliferation in the vaccine group, which could reflefct the effect of vaccine.
Project description:MC38 tumors resistant to anti-PD-1 treatment (MC38-resistant) were generated through serial in vivo passaging, and global gene expression analysis was used to compare resistant and parental tumors. MC38 and MC38-resistant tumors exhibited widespread changes in global gene expression.
Project description:To investigate the function of host TLR4 in Salmonella-mediated cancer therapy, we established MC38 tumor-bearing WT and TLR4 deletion mice for Salmonella treatment.
Project description:We investigate the single-cell landscape of the inflammatory mouse tumor model MC38, a C57BL/6 tumor cell line derived from colon adenocarcinoma. MC38 (diluted in HBSS and matrigel) was inoculated in the right unilateral flank (in the border of positions B2 and B3) of C57BL/6 mice (ref Study 16-3384 AV). Tumors were taken one day after group-out (average 150-250 mm3 at day 0), approximately 14-19 days. Tissues were dissociated and flow sorted accordingly to obtain the following groups for 10x Chromium 5' Gene Expression Profiling. Our results indicate that the degree of clonal expansion is correlated with expression of T cell exhaustion markers, and that T cells with strong exhaustion phenotype also express high levels of activation markers, such as interferon gamma.
Project description:Typhoid fever is caused by the Gram-negative bacterium Salmonella enterica serovar Typhi. Bulk RNA-sequencing (RNA-seq) data were generated from blood samples obtained from adult human volunteers enrolled in a vaccine trial involving two vaccines against typhoid fever, a plain polysaccharide vaccine, ViPS and a glycoconjugate vaccine, ViTCV. The participants were then challenged with S. Typhi in a controlled human infection model (CHIM).
