3C, with significant differences denoted with an asterisk (P<0.05).

Furthermore, several viral, molecular‐genetic tools will require the use of cre/loxP mouse models, while the available studies on sympathetic iWAT innervation were established in larger species. Just as excess adipose tissue poses clear health risks, the lack of adipose tissue, lipodystrophy, also leads to severe metabolic dysfunction, like liver steatosis and insulin resistance (Petersen et al., 2002). doi: 10.14814/phy2.14370. Next, we aimed to define the peripheral neural pathway, which can guide sympathetic postganglionic axons to the iWAT depot. Copyright © 2015 Elsevier Inc. All rights reserved. Data associated with this study and François et al., 2019 (data set Münzberg et al., 2019) were collected as part of the Stimulating Peripheral Activity to Relieve Conditions (SPARC) project and are or will be made available through the SPARC Data Portal (RRID: SCR_017041) under a CC‐BY 4.0 license. 2E) were computed for each section and compared by Students t. Data are presented as mean ± SEM and diet-induced differences are denoted with an asterisk (P<0.05).

CD31/PECAM‐1 was detected in immersion fixed bEnd.3 mouse endothelioma cell line using goat anti‐mouse/rat CD31/PECAM‐1 antigen affinity‐purified polyclonal antibody (catalog # AF3628) at 10 μg/ml for 3 hr at room temperature. Thus, while the ability of PRV for transsynaptic labeling is an advantage to identify circuits, it is important to recognize the possibility for transsynaptic labeling within preganglionic and postganglionic neurons with increasing incubation time and has been demonstrated for SC interneurons (Schramm et al., 1993; Vera & Nadelhaft, 2000; Vizzard et al., 2000).

In the mouse, the splanchnic nerve consistently branched off at the level of the sympathetic chain ganglion T12 and the elongated interganglionic strands between T12 and T13 (piercing through the diaphragm) served as a prominent landmark to identify upper abdominal chain ganglia T13, and lumbar ganglia L1–L3 (Figure 1b). Indeed, in an earlier study we found that PRV incubation times after injection into the iBAT required less incubation time (Francois et al., 2019) than after injection into iWAT. 4B), liver (Fig. During this process, both brown and beige adipose tissues play an important role. Among the 13 analyzed animals (6 females, 7 males) with successful PRV labeling in SChG, we observed consistent labeling in ipsilateral SChG T12–L1 (Figure 2b–d), even though some variability was observed for individual cases showing labeling in T7–T9 (1/13), T11 (3/13), and L2 (3/13) (Figure 2d; Table 2). 5B and 5D show the corresponding activities of the TCA cycle enzymes in IWAT and liver, respectively. Both male and female mice were used in all experiments and all animals were group‐housed at a 12:12‐hr light/dark cycle with ad lib access to food and water unless stated otherwise.

For each substrate and mitochondrial tissue source, diet-induced differences in Leak, Oxphos, and Uncoupled respiration were compared, and means denoted with an asterisk differ at P<0.05. However, also lower thoracic chain ganglia, for example, T12 and T13 may connect to the lumbar plexus nerve, as a particular spinal nerve receives postganglionic axons from both, the next cranial and also the next caudal chain ganglia (Baron et al., 1988). Expression of UCP1 mRNA (n=8) and protein (N=4) in IWAT from each treatment group was measured by quantitative real time PCR and Western blotting as described in the Methods, and means ± SEM differing at P<0.05 are denoted with an asterisk (Fig. Mice were euthanized with an overdose of CO2 and blood was removed by cardiac perfusion with saline. Bone Marrow Adiposity: Basic and Clinical Implications. Abstract Exercise training has robust effects on subcutaneous inguinal white adipose tissue (iWAT), characterized by a shift to a brown adipose tissue (BAT)-like phenotype.

HHS Our data provide the anatomical basis to suggest that CNS inputs could differentially regulate the sympathetic tone to iBAT versus iWAT.

Importantly, varicose innervation density is strongly associated with adipose tissue structure. Furthermore, animals should be inspected for off‐target labeling in the CG, as they are inconsistent with iWAT innervation. Figure 1. Mice were deeply anesthetized with an overdose of isoflurane, followed by a transcardiac syringe perfusion with ice‐cold physiological saline, then 10% neutral buffered formalin (Fisher, Passaic, NJ). 2020 Oct;28(10):1912-1921. doi: 10.1002/oby.22919.

Dashed contour indicates lymph node (ly) at dl/ing junction; exobl denotes external oblique abdominal muscle and fascia. However, it is yet to be determined if adaptations in iWAT are necessary for the beneficial systemic effects of exercise. Obesity (Silver Spring). Our finding is in line with another report indicating that TH‐positive DRG neurons, which often contained also calcitonin‐gene‐related peptide (CGRP), may rather innervate the colorectum and urinary bladder although the majority of CGRP‐positive axons in these organs apparently lacked TH immunoreactivity (Brumovsky, La, McCarthy, Hokfelt, & Gebhart, 2012).

The morphological, transcriptional and biochemical remodeling of IWAT mitochondria enhances the synthetic and oxidative capacity of this tissue and collectively underlies its expanded role as a significant contributor to the overall increase in metabolic flexibility and uncoupled respiration produced by the diet.
