Structural and Mechanistic Paradigm of Leptin Receptor Activation Revealed by Complexes with Wild-Type and Antagonist Leptins

Leptin activates its cognate receptor (LR) to regulate body weight and metabolically costly processes, such as reproduction and immune responses. Despite such benevolent pleiotropy, leptin-mediated signaling has been implicated in autoimmune diseases and b ...

Genetically altering organismal metabolism by leptin-deficiency benefits a mouse model of amyotrophic lateral sclerosis

Johan Auwerx, Pénélope Andreux

Amyotrophic lateral sclerosis (ALS) is a fatal, neurodegenerative disease that causes death of motor neurons. ALS patients and mouse models of familial ALS display organismal level metabolic dysfunction, which includes increased energy expenditure despite ...

Hypothalamic S1P/S1PR1 axis controls energy homeostasis

Dongryeol Ryu

Sphingosine 1-phosphate receptor 1 (S1PR1) is a G-protein-coupled receptor for sphingosine-1-phosphate (S1P) that has a role in many physiological and pathophysiological processes. Here we show that the S1P/S1PR1 signalling pathway in hypothalamic neurons ...

Proteome analysis of the response of Dehalobacter restrictus to cobalamin starvation

Christof Holliger, Julien Maillard, Aamani Rupakula Boyanapalli, Hauke Smidt

Dehalobacter restrictus strain PER-K23 is an obligate organohalide respiring microorganism known to solely use tetra- or trichloroethene as electron acceptors with H2 as electron donor. The catalytic enzyme, PceA, contains a corrinoid as cofactor, a trait ...

Resistance to Diet-Induced Obesity and Associated Metabolic Perturbations in Haploinsufficient Monocarboxylate Transporter 1 Mice

Pierre Magistretti, Sylvain Eric Lengacher, Luc Pellerin

The monocarboxylate transporter 1 (MCT1 or SLC16A1) is a carrier of short-chain fatty acids, ketone bodies, and lactate in several tissues. Genetically modified C57BL/6J mice were produced by targeted disruption of the mct1 gene in order to understand the ...

Cell specific ingrowth hydrogels

Matthias Lütolf

Extracellular mimetic hydrogels formed from peptide crosslinkers and polyethylene glycol monomers permit cell-controlled invasion. The use of matrix metalloproteinase specific peptides might further allow for selective control of different cell-type invasi ...

Bile Acid Binding Resin Improves Metabolic Control through the Induction of Energy Expenditure

Johan Auwerx, Kristina Schoonjans, Chikage Mataki

Besides well-established roles of bile acids (BA) in dietary lipid absorption and cholesterol homeostasis, it has recently become clear that BA is also a biological signaling molecule. We have shown that strategies aimed at activating TGR5 by increasing th ...

Expression of the leptin receptor outside of bone marrow-derived cells regulates tuberculosis control and lung macrophage MHC expression

John McKinney

Leptin is a pleiotropic hormone proposed to link nutritional status to the development of strong Th1 immunity. Because Mycobacterium tuberculosis control is affected by starvation and diabetes, we studied the role of the leptin receptor in regulating disti ...

A polymorphism in the leptin gene promoter is associated with anemia in patients with HIV disease

Jacques Fellay, Amalio Telenti

To study factors associated with anemia and its effect on survival in HIV-infected persons treated with modern combined antiretroviral therapy (cART), we characterized the prevalence of anemia in the Veterans Aging Cohort Study (VACS) and used a candidate ...

Glut2-dependent glucose-sensing controls thermoregulation by enhancing the leptin sensitivity of NPY and POMC neurons

David Genoux

The physiological contribution of glucose in thermoregulation is not completely established nor whether this control may involve a regulation of the melanocortin pathway. Here, we assessed thermoregulation and leptin sensitivity of hypothalamic arcuate neu ...
