Figure Legend Snippet: Up-regulation of BDNF-induced astroglial protein synthesis depends on the presence of neurons. (A) Schematic drawing of the lentiviral expression vector LVGFAPEGFP that expresses EGFP cell type-specifically in astrocytes under control of the simplified GFAP promoter version gfaABC 1 D. (B) Astrocytes expressed EGFP cell type-specifically after infection with LVGFAPEGFP in a neuron-glia coculture (DIV 22). Cultures were treated for 4 h with either 50 ng/ml BDNF or 2 μM TTX in the presence of 4 mM AHA and processed for 'click reaction' with a TAMRA-alkyne tag in the FUNCAT procedure. BDNF application led to an upregulation of TAMRA signal intensities up to 150%. TAMRA intensities are color coded in the lower panel (scale bar = 10 μm). (C) GFAP-positive astrocytes in monoculture (DIV 20–22) expressing EGFP show fibroblast-like morphology. No differences in TAMRA signal intensities were observed when cultures were treated analogous to (B) (scale bar = 10 μm). (D) Cultures were manipulated as described in (B). Mean TAMRA signal intensities were determined within the EGFP mask. A significant increase in TAMRA signal intensities was detected after BDNF treatment.

Figure Legend Snippet: KXS 2012 promotes neurogenesis in cultured neurons. ( A ) KXS 2012 (0.3 to 3 μg/mL) was applied onto cultured rat cortical neurons (DIV 5) for 96 h. The protein levels of PSD-95 (~95 kDa) and synaptotagmin (~60 kDa) were measured by Western blot assay (upper panel). α-Tubulin (~55 kDa) served as a loading control. Forskolin (Fsk, 50 nM) was used as a positive control. The amount of protein level was quantified (lower panel).

The treatment significantly increased the spine density of control neurons (9–16 dendrites from 6–10 neurons per 10 μm were measured for each condition). The quantification plot was shown in lower right. (C) Representative images show that KXS 2012 (3 μg/mL) and BDNF (15 ng/mL) increased the spine density compared to control.
