Figure Lengend Snippet: Effects of DR stimulation on female and male monocytes under physiological and acute inflammatory condition. DR stimulation dampens cytokine secretion of monocytes under physiological conditions (top), dependent on activated B cells. In men, this effect could not be observed. In acute inflammatory conditions induced by CpG (bottom), DR stimulation induces a switch into a proinflammatory phenotype of monocytes from women but not from men, independent of B cells; created in BioRender.com

Article Title: Screening inducers of neuronal BDNF gene transcription using primary cortical cell cultures from BDNF-luciferase transgenic mice

doi: 10.1038/s41598-019-48361-4

Figure Lengend Snippet: Screening activators of Bdnf transcription from a dopaminergic library. ( a ) Representative result obtained using a commercially available dopaminergic library. Each compound was added into Bdnf-Luc cortical cells at 13 DIV at a final concentration of 10, 100, or 1000 nM, and luciferase activity was measured in each well 6 h later. Arrowheads show active compounds (that increased luciferase activity by more than 2-fold). For compound names, see Supplementary Table . ( b ) Changes in Bdnf expression in the presence of dopamine D 1 agonist A68930 in primary cultures of rat cortical cells. At 13 DIV, cells were treated with A68930 for 1 h, and then total RNA was prepared for RT-PCR analysis. Means ± SEM (n = 3), *** p < 0.001 and **** p < 0.0001 vs. 0 nM (one-way ANOVA with Dunnett’s multiple comparisons test). ( c ) Effect of APV or FK506 on A68930-induced Bdnf expression in cultured rat cortical cells. APV (200 μM) or FK506 (5 μM) was added 10 min before the addition of A68930 (100 nM). Means ± SEM (n = 3), * p < 0.05 and **** p < 0.0001 vs. DMSO/vehicle, †††† p < 0.0001 vs A68930/vehicle (two-way ANOVA with Tukey’s multiple comparisons test).
