Supplementary Material

In our experiments, human bronchial epithelial cells were exposed to increasing pepsin concentrations in varying acidic milieus, and cell proliferation and cytokine release were assessed. In the article, we selected concentrations best representing the effects of pepsin to show in the figures. In the supplementary material, we present the figures of the effects of pepsin on cell survival and induction of cytokine release of all the pepsin concentrations and pH levels used in the statistical analysis.
