Figure Lengend Snippet: Quantification of cells in control and mutant mice reveals significant differences in the average number of TH+ and double positive neurons in the VTA and SNc. The average number of TH+ neurons and the 95% confidence intervals of counts from the VTA (A, B) and SNc (C, D) of control (dark grey shaded bars) and mutant mice (dark brown bars) in ventral, intermediate and dorsal planes. (A) The average number of TH+/Calb+ neurons in the VTA of mutant mice (light brown bars) was significantly lower than that of control mice (light grey bars) in all planes quantified. Calb+ neurons in the VTA indicated that the medial domain was not devoid of cells. (B) There were no double immunolabeled TH+/GIR2K+ neurons observed in the ventral VTA of any of the mutant GIRK2-stained slices consistent with the loss of VTA. (C) Although TH+ neurons were diminished in SNc, the average number of TH+/Calb+ neurons in the SNc was not significantly different between controls (light grey bars) and mutants (light brown bars) at any of the three horizontal planes. The blue arrowheads points to the average of TH+/Calb+ neurons. (D) The average number of TH+/GIRK2+ neurons in the SNc of mutant mice was significantly lower than that of control mice in all planes quantified. Images in A, C display TH+ (green), Calb+ (red) and TH+/Calb+ (yellow) cells while images in B, D display TH+ (green), GIRK2+ (red) and TH+/GIRK2+ (yellow) cells. Gray shading of bars indicates data from control animals with dark gray bars corresponding to average TH+ cell counts and nested light gray bars corresponding to average double positive cell counts. Brown shading indicates data from mutant animals with dark brown bars corresponding to average TH+ cell counts and nested lighter brown bars corresponding to average double positive cell counts.

Figure Lengend Snippet: Activation of endogenous MC4R enhances maturation of functional synapses and neurotransmission. a–c, Silencing of MC4R abolished the increase of mature spines and GluA1-containing spines by d-Tyr MTII (1 μm). Hippocampal neurons were cotransfected with GFP plasmid together with shMC4R and mKOrange constructs at 17–18 DIV as indicated. The neurons at 21–22 DIV were treated with d-Tyr MTII for 2 h. a, Representative images. Scale bars: top row, 10 μm; bottom rows, 5 μm. b, c, Quantification of mature spines (b) and SEP-GluA1-containing spines (c). Data were expressed as mean ± SEM; ***p < 0.001, d-Tyr MTII versus control (Con), two-way ANOVA. d–g, MC4R knockdown abolished the d-Tyr MTII-stimulated increase in neurotransmission. Hippocampal neurons were cotransfected with GFP construct together with or without shMC4R and then treated with d-Tyr MTII. d, Representative mEPSC traces. e–g, Cumulative distribution of interevent intervals (inversely proportional to frequency (e), and quantification of frequency (f), and amplitude (g) of mEPSCs. GFP-expressing neurons in the control, the shMC4R-transfected conditions, and their neighboring untransfected neurons (non GFP) were recorded. Data were presented as mean ± SEM; ***p < 0.001, d-Tyr MTII versus Control treatment, two-way ANOVA; ###p < 0.001 versus GFP cells in shMC4R (with d-Tyr MTII treatment), one-way ANOVA with Student-Newman–Keuls test (f); one-way ANOVA with Kruskal–Wallis test (g).

Article Snippet: The antibodies used include the following: anti-MC4R (N terminus; Alomone Labs); anti-pSer845 GluA1 and anti-GluA1 antibodies (PhosphoSolutions); anti-GluA1 (N terminus; Calbiochem); anti-pSer831 GluA1 (Millipore Bioscience Research Reagents). d -Tyrosine melanotan II ( d -Tyr MTII) was purchased from Phoenix Pharmaceuticals, MTII from Tocris Bioscience, and H89 from Sigma or Tocris Bioscience.

Figure Lengend Snippet: MC4R regulates surface levels of GluA1 through PKA-dependent phosphorylation. a–d, Hippocampal neurons were incubated with d-Tyr MTII (100 nm) and H89 (10 μm) for 2 h and then stained for surface GluA1. a, Representative images.
