Figure Lengend Snippet: Cross-talk between CoV-2-infected epithelial cells and immune cells activated MAIT and exacerbated inflammation. (A) Heatmap of immunological profile of Caco-2-ACE2-N cells infected with CoV-2 and PBMC cocultured with CoV-2-infected Caco-2-ACE2-N cells. mRNA fold change of immune genes was profiled by RT2 Profiler PCR Array Gene Expression Analysis. Left panel indicated group of CoV-2-infected Caco-2-ACE2-N cells, shortly named with “Caco-2 ACE2-N”; data were presented with mRNA fold change relative to Mock-treated Caco-2-ACE2-N cells. Right panel indicated group of PBMCs cocultured with CoV-2-infected Caco-2-ACE2-N cells, shortly named with “PBMC”; data were presented with mRNA fold change relative to control PBMCs cocultured with Mock-treated Caco-2-ACE2-N cells. (B) CD69 expression profile on MAIT cells in various coculture groups. “Isotype ctr” indicated isotype antibody staining; “Mock” group indicated MAIT cells cocultured with Mock-treated IECs (Caco-2-ACE-2-N); “CoV-2” group indicated MAIT cells cocultured with CoV-2-infected IECs. (C) Representative flow cytometry dot plot of IFNγ expression in NK and MAIT cells after coculture with either Mock or CoV-2 infected IECs (Caco-2-ACE-2-N). (D) Inflammatory cytokine (IFNγ, GrzB, TNFα) expression in MAIT cells determined by FACS with positive population percentage. “Mock” indicated group of MAIT cells cocultured with Mock-treated IECs; “CoV-2” indicated group of MAIT cells cocultured with CoV-2-infected IECs (E) Depletion of IL18 by adding αIL18 Ab into medium at the beginning of coculture. Cytokine expression in MAIT with depletion of IL18 in coculture or with rIL18 addition alone in PBMC culture medium. All data are represented as mean ± SEM of three replicates. Statistical significance is indicated. (ns, not significant, **p<0.01 ***p<0.001, unpaired t test or One-way ANOVA).

Article Snippet: After that, PBMC were harvested for immune genes profiling with customized RT2 Profiler PCR Array Gene Expression Kit (Qiagen).

Figure Lengend Snippet: Quality of human ORF features on GMAP chip . (a) Intensity signals from the GMAP array (X-axis) plotted against signals from the Human Gene 1.0 ST array (Y-axis) following amplification of human ORFeome v5.1 pools and hybridization of the resulting probe to each of these arrays. Common features between the two arrays were used to calculate the Pearson correlation coefficient. (b) Distribution of signal intensities from replicate GMAP or Human 1.0 ST arrays as described in (a) for shared features. Hybridization behaviour for the huORF features compared to the (c) huGene features or the (d) 22-mer hairpin features for corresponding genes.

Article Snippet: For comparative purposes, we also included up to three additional features found on the human expression profiling Affymetrix Gene 1.0 ST array for 18,088 of these sequences.
