Molecular identity of secretagogin+ paraventricular neuronsSingle‐cell mRNA transcriptome profiling of dissociated cells from the mouse paraventricular nucleus.Figure 4A Differential clustering based on secretagogin (Scgn), neuropeptide, hormone and hormone receptor mRNA expression. Secretagogin‐expressing(+) neurons typically contained corticotropin‐releasing hormone (Crh) and Nr3c1 mRNA transcripts.A1 Clusters of gene transcripts from 130 cells reveal the phenotypic segregation of PVN neurons. Increasing mRNA copy numbers were depicted by a color gradient from deep blue (not detected) to red (high numbers). Secretagogin+ neurons are indicated by red arrows. B Venn diagrams depicting the (non‐) overlapping relationships of select mRNA transcripts used to molecularly define PVN neurons.B1 Cumulative ratio of phenotypic diversity among secretagogin+ neurons. Note that Crh and/or GABA (derived from Gad1, Gad2 and Slc32a1 mRNA expression) co‐existed with secretagogin in parvocellular neurons. C, C1 Secretagogin co‐localization with GFP in the PVN (solid arrowheads) of adult CRH‐GFP (BAC) reporter mice (Alon et al, ). Open arrowhead pinpoints a single‐labeled neuron. D-I3 We found secretagogin (scgn) co‐expressed with CRH in both neuronal soma (solid arrowheads; D1-D3) and axon terminal‐like specializations (arrowheads; E-E2) in the PVN. Likewise, secretagogin+ neurons harbored, yet infrequently, tyrosine hydroxylase (TH; solid arrowheads; F-F3), GABA (G-G2), somatostatin (Sst; H-H3) and galanin (I-I2). Open rectangles denote the general location of insets. Open arrowheads indicate the lack of co‐localization.

Possible Membrane Sources of the IM.Figure 2Some of the possible scenarios for IM formation are illustrated here. According to the maturation model, upon induction of autophagy, membrane may be directly derived from the ER by folding (A), or in the form of vesicular transport (B). In the assembly model, membrane may be assembled de novo at the site of IM formation, originating from nonvesicular transport, such as micellar, as shown in (C), or local synthesis (D). See text for further details.

Figure 9Laser-induced mitochondrial membrane depolarization in L6 myoblasts shows gradual depolarization of elements along the IMM, visualized using live-cell Airyscan microscopy. Representative images of laser-induced depolarization time series from L6 myoblast, stained with ΔΨm-dependent dye, Rho123. Images show LUT color-coded for Rho123 FI. White and blue pixels represent most and least intense ΔΨm, respectively. See legend of LUT colors on the right. Note that at the first time point (~0.15 sec) white arrow points to box marking area of mitochondrion exposed to phototoxic pulse of 2-photon laser (≤5 msec), inducing depolarization. Ensuing frames show wavelike depolarization away from site of perturbation (arrowheads). Scale bar = 500 nm. N = 3 independent experiments. (See Movie EV 2 for time series.) Profile plot showing Rho123 pixel intensity as function of distance along mitochondrion in A. Note that zero value in the X axis corresponds to top area of the mitochondrion shown in A, near site of 2-photon laser exposure (box). Red line corresponds to frame immediately before depolarization (~0.15 sec); green, blue, purple, and dark purple lines correspond to ~0.30, ~0.60, ~1.05, and ~2.10 sec, respectively, after initial depolarization, showing wavelike dissipation of ΔΨm over time. Laser-induced mitochondrial membrane depolarization in living human skin fibroblasts co-stained with TMRE and MTG and imaged with Airyscan, showing gradual depolarization of elements along the IMM. Time-lapse images of merged green (MTG) and red (TMRE) channels following laser-induced mitochondrial membrane depolarization. Note that, at the first time point (0.3 sec), white arrow points to box marking area of mitochondrion exposed to phototoxic pulse of 2-photon laser (≤5 msec), inducing depolarization. Depolarization is marked by the dissipation of the ΔΨm-dependent dye (TMRE) while the green (MTG) signal persists. Scale bar = 1 µm. N = 4 independent experiments. TMRE channel from C, showing gradual of the loss of TMRE along the IMM. Note that although depolarization has largely completed at the area near the phototoxic stimulus already at 0.9 sec, some specific regions at the very top maintain ΔΨm while others depolarize. Quantification of ΔΨm using TMRE FI from C-D. Measurement of TMRE pixel intensities immediately after laser-induced depolarization at site distal (≥ 10 µm) vs. proximal (≤ 1 µm) to box. N = 4 independent experiments; see specific p values in panel. Quantification of C-D. Percentage of mitochondria that depolarize in a wavelike (i.e., gradual) vs. instantaneous manner after laser-induced depolarization. Note: imaging at high temporal resolution (~100-500 msec/frame) reveals wavelike depolarizations predominate, suggesting the ΔΨm is composed of multiple, disparate electrochemical domains along the IMM. The time scale of propagation of depolarization is slower than the propagation of electrical phenomena. N = 4 independent experiments.
