Additional file 2: Figure S2. of Histamine upregulates the expression of histamine receptors and increases the neuroprotective effect of astrocytes

Abstract

The effects of HR antagonists on expression levels of the histamine H1, H2, and H3 receptor subtypes. The astrocytes were exposed to the H1R antagonist cetirizine (10 μM), the H2R antagonist ranitidine (10 μM), and the H3R antagonist carcinine (10 μM) for 24 h. The expression levels of the histamine H1, H2, and H3 receptor subtypes were examined by quantitative RT-PCR. The data are presented as the mean ± s.e.m. of three independent experiments. (TIFF 365 kb
