Subsequently, the mRNA expression levels of cytokines were quantified in L8824 cells after incubation with the different Hb preparations and heme, and this revealed that the expression of pro-inflammatory cytokines was almost significantly upregulated in heme- and Hb-Fe 4+ -treated cells, especially at 24 h.
Consistent with the above results, based on the analysis of GEO dataset analysis, the GSE16011 dataset showed an increasing trend in the number of patients with high-grade glioma ( Figure 4E ); similar results were observed for the GSE4412 dataset ( Figure 4F ) and the GSE43289 dataset ( Figure 4G ). qRT–PCR and immunohistochemistry (IHC) staining for SLC11A1 were used to evaluate SLC11A1 expression in tumor tissue samples and for further validation.
There was a nominally significant association between CD28 expression on CD4+ T cells and response (CR or PR) at day 180 after CAR-T cell infusion (91.3% CD28+, range 56.9–99.9% for responders versus 79.4%, range 44.6–99.9% for non-responders, p=0.048, t-test), but no other statistically significant associations between clinical outcomes and the frequencies of immune cell subsets in PBMC samples or the infusion products.
