There was a trend for psyllium plus inulin-treated mice having higher levels of systemic helper T and cytotoxic T cells compared to psyllium plus RS-treated (p = 0.0882 for CD4+ T cells and p = 0.1085 for CD8+ T cells; Supplementary Figure S3b), consistent with the local tumour immune analysis. Here, CD8A is linked to neoplasm.
