Supplemental Legends Supplemental Figure 1. extract suppressed -induced CXCL1, but not IL-13- induced CCL26. Submerged normal human bronchial epithelial (NHBE) cells were pretreated with 1:32 w/v Aspergillus fumigatus () or heat-treated extract (7 for 3 minutes) for 1 hour prior to treatment for 6 hours. Cell lysates were collected to assess expression of (A) CXCL1 mrna by RT-PCR. extract was incubated with (5 µg/ml), IL-13 (1 ng/ml), or IL-17A (1 ng/ml) to analyze the expression of (B) IFN-β mrna, (C) CCL26 mrna, or (D) CXCL8 mrna, respectively, by RT-PCR. Similarly, NHBE cells were pretreated with 1:32 w/v house dust mite (HDM) or 1:32 w/v cockroach (CR) extract for 1 hour prior to treatment for 6 hours. (E, F) Cell lysates were collected to assess expression of CXCL1 mrna by RT-PCR. Data represent mean + SEM of three independent experiments;, p <.1 by t-test when compared to medium only control;, p <.1 by t-test when compared to poly I:C or IL-17A stimulated cells;, not significant by t-test. Supplemental Figure 2. extract suppressed IFN-β-activated STAT1. Submerged NHBE cells were pretreated with or without 1:32 w/v extract or the PAR-2 activator AC-55541 (1 nm) 1 hour prior to stimulation with IFN-β (1 IU/ml) and cell lysates were collected at indicated time points. (A) Cellular protein was collected for Western blot. (B) Expressed bands of phospho-stat1 were quantified by using software Image J and normalized to internal control actin. Data represent mean + SEM of three independent experiments and images of Western blot are representative of three independent experiments;, p <.1 by t-test when compared to medium only control;, p <.1 by t-test when compared to stimulated cells at same E2
time point ;, not significant by t-test. Supplemental Figure 3. Inhibition of PTPN11 reversed mediated suppression of CXCL1 induced by or IFN-β. NHBE cells were pretreated with the PTPN11 inhibitor C- 87877 (1 nm) for 3 hours prior to adding 1:32 w/v extract to the medium. After 1 hour of incubation, cells were stimulated with (A,B) (5 µg/ml) or (C,D) IFN-β (1 IU/ml) for 6 hours. Cell lysates were collected to assess expression of (A,C) CXCL1 mrna by RT- PCR and (B,D) CXLC1 protein by ELISA. Data represent mean + SEM of six independent experiments;, p <.1 by t-test when compared to medium only control;, p <.1 by t-test when compared to or IFN-β stimulated cells;, not significant by t-test.
