To gain further insight into the role of PPARγ in ILC2s in the CRC setting, we evaluated the expression of PPARγ, as well as of CPT1A, one of the well-characterized PPARγ-direct target genes36, in freshly-sorted ILC2s from both PBMCs and TILs of CRC patients. The gene discussed is PPARG; the disease is colorectal carcinoma.
