IL36A and necrotizing enterocolitis: We also observed a trend towards increased expression of the IL-36 isoforms IL36A (mostly undetectable in each of the healthy groups, Supplementary Fig. 5e) and IL36B (mostly undetectable in Control and Recovered, but the higher expression in Healthy, Supplementary Fig. 5f) and IL36G (up to 2.5-fold, Supplementary Fig. 5g) in “Afflicted” and “Necrotic” NEC sections compared to controls.
