Figure Lengend Snippet: Impact of M. globosa infection on PAR2 activation, IL-17 production, and TJ integrity in HaCaT cells (A) Cell survival rate was detected by CCK8 assay. (B–D) Protein expression and correlation analysis in HaCaT cells infected with 30 MOI M. globosa was evaluated by western blot at various time. (E and F) mRNA levels and correlation analysis were measured by reverse transcription quantitative PCR (RT-qPCR). Red indicated upregulated gene expression, green indicated downregulated gene expression. (G) IL-17A levels were detected by ELISA test in the supernatant of HaCaT cells infected with 30 MOI M. globosa . Red indicated upregulated gene expression (C and E) or positive correlation (D and F), blue indicated downregulated gene expression (C and E) or negative correlation (D and F).These experiments (A, B, E, and G) were representative of 3 independent experiments. Values are means ± SD. a two-way ANOVA with Bonferroni’s (A), or Dunnet’s (G) multiple comparisons test was applied. ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001. Correlation analysis is performed using Pearson’s correlation coefficient analysis. See also .

Article Snippet: Cell viability was determined with the Cell Counting Kit-8 (CCK8, Beyotime, Shanghai, China), following the manufacturer’s protocol.
