    Alomone Labs rabbit anti p75
    Effect of septo-hippocampal pathway axotomy in cholinergic septal neurons . A , Light microscopy of coronal sections stained for AChE 3 or 21 days after lesion procedure, showing the early effect of axotomy in cholinergic projections towards the hippocampus. Twenty-one days after axotomy, AChE-positive terminals are strongly reduced in the ipsilateral side of the lesion, as compared to the contralateral side (scale bar 1 mm). Inferior panels, magnification inset of AChE-positive neurites in dentate gyrus (scale bar 200 μm). B , Light microscopy of immunohistochemistry anti-ChAT in coronal sections, showing the effects of the axotomy in cell bodies of cholinergic septal neurons, 3 or 21 days after axotomy. Twenty-one days after the lesion, the number of ChAT-positive neurons is clearly reduced on the ipsilateral side of the medial septum (CL, contralateral; IL, ipsilateral. Scale bar: 1 mm). C , Time course of ChAT- and <t>p75-positive</t> neuron loss after axotomy. The graph shows the quantification of ChAT- or p75-immunopositive neurons in the medial septum from serial sections of brains at 3, 7, 14 and 21 days after the lesion. Note that the numbers of ChAT- and p75-immunopositive cells decay with similar kinetics but with a different slope between 7-14 days.

    The number of neurons that are positive only for p75 is increased in the ipsilateral side after axotomy . A , Confocal microscopy of double-immunofluorescence anti-ChAT/anti-p75 reveals an increase in the number of neurons that are positive only for p75 at different times after the axotomy. The superior panel is a panoramic view of the medial septum at 14 days after axotomy (scale bar: 1 mm). The central and inferior panels are magnification insets (scale bar: 200 μm) of neurons contralateral and ipsilateral to the lesioned side, showing p75-positive and ChAT-negative cells as indicated by the white arrows. B , The graph shows the percentage of total septal neurons expressing p75 that are p75-positive and ChAT-negative at 1, 3, 7 or 14 days after axotomy. Black bars represent the control side of the septum and white bars represent the side ipsilateral to the lesion. Asterisk indicates significance level p < 0.05.

    Cholinergic septal neurons do not undergo apoptosis after axotomy . A , Triple-immunofluorescence against Neu-N (neuronal marker), GFAP (astroglial marker) and activated Caspase-3 shows no colocalization of the apoptotic marker with neurons at different time points (1, 3, 7, 14 days) after axotomy. There is an increase in the number of cells that are immunopositive for activated caspase-3 with time. The correlation between GFAP and activated Caspase-3 suggests that astrocytes are undergoing apoptosis (scale bar: 50 μm).

(A-I) Double-label immunostaining for GS (A, D and G) and P75 NTR (B, E and H) in control ( Ctl , A-C ) and transgenic ( TG , D-I ) mice 7d and 14d after tamoxifen treatment. The retina of control mice showed weak immunoreactivity of P75 NTR (A-C) . TG mice showed upregulation of P75 NTR predominantly by surviving Müller cells 7d (D-F) and 14d (G-I) after TMX-induced Müller cell ablation. Small arrows in (D and G) point to regions of Müller cell loss, and large arrows in (G) indicate defects in the outer limiting membrane following Müller cell ablation. GCL = ganglion cell layer, INL = inner nuclear layer, ONL = outer nuclear layer. (J and K) Western blots showed significant upregulation of GFAP concomitantly with overexpression of P75 NTR 7d and 14d after Müller cell ablation in TG mice. † P < 0.05 and * P < 0.01, TG vs. control, N = 4–8 in each group.

    Intravitreal injection of recombinant NT3 and blockage of P75 NTR protected photoreceptor degeneration. Intravitreal injection was performed in transgenic mice 3d and 6d after tamoxifen induced Müller cell ablation, with one eye receiving the testing reagent and the contralateral eye receiving balanced salt solution (BSS). Doses of injection: (1) NT3, 0.4 μg; (2) P75 NTR rabbit polyclonal Ab (1:1 dilution) and (3) 0.4 μg NT3 + 1:1 dilution of P75 NTR Ab.

( B ) The levels of acetylated histone H3 were determined in neuroblastoma tumor xenografts of vehicle- and entinostat-treated mice by Western blot. Each lane was loaded with a sample that was obtained from an individual animal (in ( A , B ): four animals that were treated with vehicle and five animals that were treated with entinostat; in ( C – F ), three animals that were treated with either vehicle or entinostat). Scatter plots indicate the absolute values of densitometric ratios and are the mean ± SD of three independent Western blots. * p < 0.05, *** p < 0.001, ns = not significant by Student’s t test.

    Effect of septo-hippocampal pathway axotomy in cholinergic septal neurons . A , Light microscopy of coronal sections stained for AChE 3 or 21 days after lesion procedure, showing the early effect of axotomy in cholinergic projections towards the hippocampus. Twenty-one days after axotomy, AChE-positive terminals are strongly reduced in the ipsilateral side of the lesion, as compared to the contralateral side (scale bar 1 mm). Inferior panels, magnification inset of AChE-positive neurites in dentate gyrus (scale bar 200 μm). B , Light microscopy of immunohistochemistry anti-ChAT in coronal sections, showing the effects of the axotomy in cell bodies of cholinergic septal neurons, 3 or 21 days after axotomy. Twenty-one days after the lesion, the number of ChAT-positive neurons is clearly reduced on the ipsilateral side of the medial septum (CL, contralateral; IL, ipsilateral. Scale bar: 1 mm). C , Time course of ChAT- and <t>p75-positive</t> neuron loss after axotomy. The graph shows the quantification of ChAT- or p75-immunopositive neurons in the medial septum from serial sections of brains at 3, 7, 14 and 21 days after the lesion. Note that the numbers of ChAT- and p75-immunopositive cells decay with similar kinetics but with a different slope between 7-14 days.

    Effect of septo-hippocampal pathway axotomy in cholinergic septal neurons . A , Light microscopy of coronal sections stained for AChE 3 or 21 days after lesion procedure, showing the early effect of axotomy in cholinergic projections towards the hippocampus. Twenty-one days after axotomy, AChE-positive terminals are strongly reduced in the ipsilateral side of the lesion, as compared to the contralateral side (scale bar 1 mm). Inferior panels, magnification inset of AChE-positive neurites in dentate gyrus (scale bar 200 μm). B , Light microscopy of immunohistochemistry anti-ChAT in coronal sections, showing the effects of the axotomy in cell bodies of cholinergic septal neurons, 3 or 21 days after axotomy. Twenty-one days after the lesion, the number of ChAT-positive neurons is clearly reduced on the ipsilateral side of the medial septum (CL, contralateral; IL, ipsilateral. Scale bar: 1 mm). C , Time course of ChAT- and p75-positive neuron loss after axotomy. The graph shows the quantification of ChAT- or p75-immunopositive neurons in the medial septum from serial sections of brains at 3, 7, 14 and 21 days after the lesion. Note that the numbers of ChAT- and p75-immunopositive cells decay with similar kinetics but with a different slope between 7-14 days.

    Expression of p75NTR and histone H3 acetylation in neuroblastoma tumor xenografts and different organs of entinostat-treated mice. ( A , C – F ) Athymic nude mice bearing xenograft of SH-SY5Y cells were treated daily for 10 days with either the vehicle or entinostat (20 mg/kg) by oral gavage. The mice were sacrificed, the tumor xenografts and the indicated organs were resected, and the tissue extracts were analyzed for p75NTR levels by Western blot. ( B ) The levels of acetylated histone H3 were determined in neuroblastoma tumor xenografts of vehicle- and entinostat-treated mice by Western blot. Each lane was loaded with a sample that was obtained from an individual animal (in ( A , B ): four animals that were treated with vehicle and five animals that were treated with entinostat; in ( C – F ), three animals that were treated with either vehicle or entinostat). Scatter plots indicate the absolute values of densitometric ratios and are the mean ± SD of three independent Western blots. * p < 0.05, *** p < 0.001, ns = not significant by Student’s t test.
