In some experiments 10 μM L-thiocitrulline (nitric oxide synthase inhibitor) or 10 μM SB203580 (MAPK p38 inhibitor) were added for further 7 or 14 days, respectively. Immunohistochemistry using the avidin–biotin technique was performed to detect cholinergic neurons, as described previously (Zassler and Humpel, 2006). All incubations were processed free-floating at 4 °C for 2 days including 0.1% Triton, allowing good penetration of the antibody into the slices from Dabrafenib supplier both sides. Fixed slices

were rinsed 30 min with 0.1% Triton/PBS (T-PBS) at room temperature and pre-treated for 20 min with 20% methanol/1% H2O2/PBS. Then the slices were washed three times for 10 min with PBS, blocked with 20% horse serum/0.2% BSA/T-PBS and then incubated with the primary antibody against JQ1 datasheet goat anti-choline‐acetyltransferase (1:750, Millipore, USA) in 0.2% BSA/T-PBS for 2 days at 4 °C. Slices were washed and incubated with secondary biotinylated anti-goat antibody (1:200, Vector Laboratories), for 1 h at room temperature. After rinsing three times in PBS, slices were incubated in avidin–biotin complex solution (ABC; Elite Standard PK 6100, Vector Laboratories) for 1 h, then washed three times in 50 mM Tris-buffered saline (TBS) and the signal was detected using 0.5 mg/ml 3,3′diaminobenzidine (DAB) in TBS

with 0.003% H2O2 as substrate. Slices were then rinsed in PBS and mounted on glass slides. Slices were extracted in 100 μl ice-cold sodium-phosphate buffer (PBS) with protease-inhibitor cocktail (Sigma, Germany) using an ultrasonic device (Branson sonifier 250) and centrifuged at 16 000 ×g for 10 min at 4 °C. Inflammatory markers and MMP-2 were analyzed in slice extracts using a rat Multiplex ELISA (SearchLight®; Aushon Biosystems), as described previously ( Marksteiner et al., 2011 and Pirchl Methamphetamine et al., 2010). All neuronal counts

were based on individual sections and show total number of neurons per slices. The number of microscopically detectable immunoreactive ChAT+ neurons was counted in the whole slice visualized under a 40× objective by an investigator blinded to the treatment code. Quantitative data are presented as mean ± SEM. Multistatistical analysis was obtained by one way ANOVA, followed by a subsequent Fisher PLSD posthoc test by comparing controls against the respective treatments, where p < 0.05 represents statistical significance. This study was supported by the Austrian Science Funds (P191220-B05 and L429-B05). We thank Ursula Kirzenberger-Winkler for excellent technical help. "
“Musashi (Msi) was first identified in the external sensory organ in the peripheral nervous system (PNS) of Drosophila and is required for asymmetric cell division of the sensory organ precursor (SOP) cell of the Drosophila adult external sensory organ, and it functions by controlling the expression of Tramtrack69 (TTK69) ( Nakamura et al., 1994). Msi contains two RNA recognition motifs (RRMs) as a highly conserved RNA-binding domain.
