Additionally, colonocytes that were FTH1+ in those living with IBD in remission displayed significant depletion in MTOR and LGALS transcripts (Fig. 4D), while colonocytes that were FTH1+ in those living with PD displayed a substantial enrichment in MHC I, as compared to FTH1+ colonocytes from NHC. Here, FTH1 is linked to inflammatory bowel disease.
