Figure Legend Snippet: proBNDF-mediated p75NTR activation in cortical PV cells reduces their perisomatic boutons. A , Experimental approach. B , The intensity of perisomatic PV immunostaining (green) is reduced in the binocular visual cortex ipsilateral to the minipump-releasing mut-proBDNF (Ipsi) compared with the contralateral cortex (Contra) in the same animal. On the other hand, perisomatic PV intensity in the ipsilateral cortex of PV_Cre;p75 flx/flx mice is similar to that observed in the contralateral, untreated cortex. C , Low ( C1 ) and high ( C2 ) magnification of PNN (red, WFA staining) enwrapping PV cells (green) shows a dramatic reduction in both PNN density and intensity in the visual cortex infused with mut-proBFNF. This effect is abolished in PV_Cre;p75 flx/flx mice. Scale bars: C1 , 100 μm; B , C2 , 10 μm. D , Quantification of the mean intensity of perisomatic PV-positive puncta in ipsilateral compared with contralateral cortex. I/C ratio is obtained for each animal and then averaged between different animals. Mean I/C ratio is significantly reduced in Mut-proBDNF-infused p75 Ctrl mice compared with Mut-proBDNF-infused PV_Cre;p75 flx/flx mice (unpaired t test, df = 8, t = 6.077, p = 0.0003). E , The ratio of mean PNN intensity around PV cells in ipsilateral versus contralateral cortex is significantly lower in p75 Ctrl than PV_Cre;p75 flx/flx mice infused with mut-proBDNF (unpaired t test, df = 8, t = 15.33, p

Figure Legend Snippet: Modulation of tPA activity affects the formation of PV cell innervations during early postnatal development. A , Control EP18 PV cell ( A1 , green represents Ctrl). B , PV cell treated with the tPA inhibitor PPACK from EP10–EP18 shows simpler axonal arborization, contacting less potential targets ( B2 , blue represents NeuN-positive somata). C , PV cell treated with tPA in the same time window shows a very complex axonal arbor ( C2 ) and an increase in both terminal branching and perisomatic boutons ( C3 , arrowheads) compared with control cells ( A2 , A3 ). D , PV cell treated simultaneously with tPA and mut-proBDNF shows axonal branching and perisomatic innervation more similar to those formed by PV cell treated with mut-proBDNF alone, suggesting that the effects of tPA application may be mediated by a decrease in endogenous proBDNF/mBDNF ratio. Stars indicate NeuN-positive somata that are not innervated. Scale bars: A1–D1 , 50 μm; A2–D2 , 10 μm; A3–D3 , 5 μm. E , Perisomatic boutons density (one-way ANOVA, F (3,20) = 121.2, p

Figure Legend Snippet: proBNDF-mediated p75NTR activation in cortical PV cells restores ocular dominance plasticity in adult visual cortex in vivo . A , Typical VEP responses to the stimulation of either contralateral (blue) or ipsilateral (red) eye to the cortex in which the recording is performed in p75NTR Ctrl mice infused with either vehicle or mut-proBDNF, and PV_Cre;p75NTR flx/flx mice infused with mut-proBDNF. Calibration bars: 50 μV, 100 ms. B , C/I VEP ratio mean values. Three days of monocular deprivation do not affect the C/I VEP ratio in adult mice, although it leads to a significant decrease in the C/I VEP ratio in animals treated with mut-proBDNF. Mut-proBDNF effects are, however, abolished in PV_Cre;p75 flx/flx mice (one-way ANOVA, F (2,18) = 8.903, p = 0.0021). p75NTR Ctrl + vehicle: n = 9 mice; p75NTR Ctrl + mut-proBDNF: n = 5 mice; PV_Cre;p75 flx/flx +mut-proBDNF: n = 7 mice. C , ODI of p75NTR Ctrl mice infused with vehicle solution and PV_Cre;p75 flx/flx mice infused with mut-proBDNF are not significantly different from those of undeprived animals, whereas ODIs in p75 Ctrl mice treated with mut-proBDNF are significantly shifted toward the open eye (one-way ANOVA, F (2,443) = 5.203, p = 0.0058). D , Mean spontaneous discharge is significantly increased only in p75 Ctrl mice treated with mut-proBDNF (one-way ANOVA, F (2,443) = 4.580, p = 0.0107). p75NTR Ctrl + vehicle: n = 9 mice, 174 cells; p75NTR Ctrl + mut-proBDNF: n = 5 mice, 147 cells; PV_Cre;p75 flx/flx +mut-proBDNF: n = 6 mice, 125 cells.

A , Control PV cell ( A1 , Ctrl, green) at EP32 with exuberant innervation field characterized by extensive branching contacting the majority of potential targets, dense boutons along axons ( A2 ), and terminal branches with prominent and clustered boutons ( A3 ; arrowheads) around NeuN-positive somata (blue). B , PV cell treated with wt-proBDNF from EP26-EP32 shows overall similar axon size ( B1 ), percentage of potentially targeted neurons ( B2 ), and perisomatic innervations ( B3 ) as control, untreated PV cells. C , PV cell treated with mut-proBDNF from EP26-EP32 shows a drastic reduction both in percentage of innervated cells ( C2 ) and perisomatic innervation ( C3 ). Stars indicate NeuN-positive somata that are not innervated. Scale bars: A1–C1 , 50 μm; A2–C2 , 10 μm; A3–C3 , 5 μm. D , Perisomatic bouton density (one-way ANOVA, F (2,18) = 93.34, p

Figure Legend Snippet: HBpF-proBDNF design and production. A. Schematic representation of recombinant HBpF-proBDNF protein. HBpF-proBDNF contains a signal peptide, an amino-terminal 6xHis-tag, followed by a Biotin-Acceptor-Peptide (BAP) sequence, a linker (L), a PreScission ™ Protease (PP) cleavage site and a Flag-tag (Flag). The ProBDNF sequence has been mutated with a KR to AA mutation at the furin dibasic cleavage site between the pro-domain and the mature part of BDNF. B. HEK293T cells were transfected with HBpF-proBDNF and BirA plasmids. After Ni-NTA pulldown and cleavage with the PreScission ™ Protease, the eluates were analyzed by Western blot and blotted with anti-biotin, anti-Flag and anti-BDNF. C. Purified HBpF-proBDNF was incubated with PC12 cells lysates, without a protease inhibitors, for 1h at room temperature. Incubation of HBpF-proBDNF with lysis buffer for 1h at room temperature was used as a control. Immunoblots against BDNF were performed to visualize the degradation of HBpF-proBDNF.

BirA Ni-NTA eluate was used as control treatment. After stimulation, cells were lysed and HBpF-proBDNF and associated protein were recovered on SA beads. Cleavage with PP was performed for 16 hours and the resulting PP eluate was collected. Cell lysates (Input) and PP eluate samples were then analyzed by immunoblotting for p75NTR, SorCS2 and FLAG.
