Abstract

Bile acids (BAs) improve metabolism and exert anti-obesity effects through the activation of the Takeda G protein-coupled receptor 5 (TGR5) in peripheral tissues. TGR5 is also found in the brain hypothalamus, but whether hypothalamic BA signaling is implicated in body weight control and obesity pathophysiology remains unknown. Here we show that hypothalamic BA content is reduced in diet-induced obese mice. Central administration of BAs or a specific TGR5 agonist in these animals decreases body weight and fat mass by activating the sympathetic nervous system, thereby promoting negative energy balance. Conversely, genetic downregulation of hypothalamic TGR5 expression in the mediobasal hypothalamus favors the development of obesity and worsens established obesity by blunting sympathetic activity. Lastly, hypothalamic TGR5 signaling is required for the anti-obesity action of dietary BA supplementation. Together, these findings identify hypothalamic TGR5 signaling as a key mediator of a top-down neural mechanism that counteracts diet induced obesity.

Abstract

Erratum in : Metabolic and Innate Immune Cues Merge into a Specific Inflammatory Response via the UPR. [Cell. 2019]; International audience; Innate immune responses are intricately linked with intracellular metabolism of myeloid cells. Toll-likereceptor (TLR) stimulation shifts intracellular metabolism toward glycolysis, while anti-inflammatorysignals depend on enhanced mitochondrial respiration. How exogenous metabolic signals affect theimmune response is unknown. We demonstrate that TLR-dependent responses of dendritic cells (DC)are exacerbated by a high fatty acid (FA) metabolic environment. FA suppress the TLR-inducedhexokinase activity and perturb tricarboxylic acid cycle metabolism. These metabolic changesenhance mitochondrial reactive oxygen species (mtROS) production and, in turn, the unfolded proteinresponse (UPR) leading to a distinct transcriptomic signature, with IL-23 as hallmark. Interestingly,chemical or genetic suppression of glycolysis was sufficient to induce this specific immune response.Conversely, reducing mtROS production or DC-specific deficiency in XBP1 attenuated IL-23expression and skin inflammation in an IL-23-dependent model of psoriasis. Thus, fine-tuning of innateimmunity depends on optimization of metabolic demands and minimization of mtROS-induced UPR.

15. Psoriasis-like inflammation in K14PPARu03b2/u03b4 transgenic mice selectively overexpressing PPARu03b2/u03b4 in keratinocytes.

Author

Dezoteux, Frédéric, Quemener , Sandrine, and Fleury , Sébastien

Abstract

Psoriasis is an inflammatory skin disease affecting 2-3% of the general population and whose precise aetiology remains poorly understood. Several lines of evidence suggest that the nuclear receptor peroxisome proliferator activator (PPAR) u03b2/u03b4, known to regulate epithelial differentiation, proliferation, wound healing and epidermal barrier recovery, contributes to psoriasis pathogenesis. It is unclear, however, whether activation of PPAR u03b2/u03b4 is sufficient to trigger psoriasis-like inflammation.Overexpression of PPARu03b2/u03b4 in keratinocytes in mice leads to death 8 days after birth despite food intake and integrity of the skin barrier. The reason of lethality remains to be elucidated. K14PPARu03b2/u03b4 Tg mice developed inflammatory cutaneous lesions 5 days after birth, that worsened with time. These skin lesions shared similar clinical, histological and immunological features with human psoriasis. However, some disparities with human lesions were observed such as for some cytokine (IL-4, IL-33) mRNA profiles and immunologic responses. T-cells, commonly found in psoriasis lesions, were rare in skin of K14PPARu03b2/u03b4 Tg mice, probably as a consequence of an immature immune system at 5 days of life. Microarray analysis showed a similar transcript profile in K14PPARu03b2/u03b4 Tg mice compared to human psoriasis. Though K14PPARu03b2/u03b4 Tg mice may represent an interesting experimental model to better understand the pathophysiology of the early stages of human psoriasis.

Abstract

Retinoic acid receptor-related orphan receptor-alpha (RORα) is a transcription factor from the nuclear receptor family expressed by immune cells and involved in the development of obesity, insulin resistance (IR) and non-alcoholic steatohepatitis (NASH). It was recently reported that mice deficient for RORα in macrophages develop more severe NASH upon high fat diet (HFD) feeding due to altered Kupffer cell function. To better understand the role of RORα in obesity and IR, we independently generated a macrophage RORα-deficient mouse line. We report that RORα deletion in macrophages does not impact on HFD-induced obesity and IR. Surprisingly, we did not confirm an effect on NASH development upon HFD feeding nor in the more severe and obesity-independent choline-deficient, L-amino acid-defined diet model. Our results therefore show that RORα deletion in macrophages does not alter the development of obesity and IR and question its role in NASH. [ABSTRACT FROM AUTHOR]

Abstract

Plasma growth differentiation factor-15 (GDF-15) levels increase with obesity and metabolic dysfunction-associated steatotic liver disease (MASLD) but the underlying mechanism remains poorly defined. Using male mouse models of obesity and MASLD, and biopsies from carefully-characterized patients regarding obesity, type 2 diabetes (T2D) and MASLD status, we identify adipose tissue (AT) as the key source of GDF-15 at onset of obesity and T2D, followed by liver during the progression towards metabolic dysfunction-associated steatohepatitis (MASH). Obesity and T2D increase GDF15 expression in AT through the accumulation of macrophages, which are the main immune cells expressing GDF15. Inactivation of Gdf15 in macrophages reduces plasma GDF-15 concentrations and exacerbates obesity in mice. During MASH development, Gdf15 expression additionally increases in hepatocytes through stress-induced TFEB and DDIT3 signaling. Together, these results demonstrate a dual contribution of AT and liver to GDF-15 production in metabolic diseases and identify potential therapeutic targets to raise endogenous GDF-15 levels., (© 2024.
