Article Title: Human intrahepatic ILC2 are IL-13 positive amphiregulin positive and their frequency correlates with model of end stage liver disease score

doi: 10.1371/journal.pone.0188649

Figure Lengend Snippet: (A) ILC gating strategy. Intrahepatic lymphocytes were freshly isolated and gated on the CD45 pos CD3 neg population. The total ILC population was defined as lineage neg and CD127 pos . Of these, ILC1 were defined as CD117 neg CRTH2 neg , ILC2 as CD117 pos/neg CRTH2 pos and ILC3 as CD117 pos CRTH2 neg. (B) Frequency of the total ILC population among the CD3 neg CD45 pos population. (C) Frequencies of the three major ILC subsets in the total intrahepatic ILC in different inflammatory liver diseases. AILD: Autoimmune Liver Diseases (PSC, PBC, AIH); NASH: Nonalcoholic Steatohepatitis; ALD: Alcoholic Liver Disease. (* = p <0.05 by Kruskal Wallis test). (D) Distribution of NKp44 expression among intrahepatic ILC. ILC3 were NKp44 pos (NCR pos ) or NKp44 neg (NCR neg ). (E) Frequencies of NKp44 expression by intrahepatic ILC3 in normal and diseased livers. Summary data are median ± Interquartile range.

Article Snippet: Freshly isolated lymphocytes were stained on ice with antibodies against functional surface markers of interest together with antibodies to identify ILC subsets including: CD3 (UCHT1, BioLegend), CD45 (5B1, Miltenyi Biotec), CD127 (eBioRDR5, eBiosciences) and lineage markers (CD1a (HI149), CD11c (MJ4-27G12), CD14 (TUK4), CD16 (VEP13), CD19 (LT19), CD34 (AC136), CD94 (REA113), CD123 (AC145), BDCA2 (AC144), FceR1 (CRA1) (all from Miltenyi Biotec)) to identify total ILC, CRTH2 (BM16) and CD117 (104D2) (both from BioLegend) to distinguish ILC1 (CRTH2-CD117-), ILC2 (CRTH2+CD117+/-) and ILC3 (CRTH2-CD117+).

Figure Lengend Snippet: (A) The CD45 pos CD3 neg lineage neg CD127 pos CRTH2 pos ILC2 subset was gated and expression of the IL-2 receptor α-chain, CD25, was analysed. CD25 representative overlay and summary data in normal and diseased livers is shown. (** = p <0.01 by Mann Whitney test). In the histogram overlay the dotted line represents isotype staining and the shaded histogram reports CD25 staining. (B) Human inflamed liver supernatant was analysed for IL-2, IL-7, IL-9 and IFN-γ. The secretion of cytokines by normal and inflamed human liver tissue was analysed by luminex of 24-hour liver tissue supernatants prepared for 1g of tissue/1ml culture medium. (C) IL-33 production by human liver tissue (Normal and diseased) and (D) IL-33 production by Primary human biliary epithelial (BEC). IL-33 in 24-hour supernatants generated by 1g liver tissue/1ml medium or BEC cells unstimulated, stimulated with IFN-γ and TNF-α or with lipopolysaccharide (LPS) was analysed by ELISA. Summary data are median ± Interquartile range.
