Lentiviral vectors have proven to be promising tools for transduction of brain cells in vivo and in vitro. In this study, we have examined the central nervous system (CNS) transduction efficiencies and patterns of a self-inactivating simian immunodeficiency virus (SIVmac)-derived lentiviral vector pseudotyped with glycoproteins from the vesicular stomatitis(More)
In several rodent strains such as the New Zealand Obese (NZO) mouse, the incidence of obesity-associated diabetes mellitus is much higher in males than in females. In the present study, we investigated the effects of ovariectomy on glucose homeostasis in female NZO mice in order to elucidate the mechanism of their diabetes resistance. NZO females were(More)
Signaling through the mammalian target of rapamycin complex 1 (mTORC1) and its effectors the S6-kinases (S6K) in the hypothalamus is thought to be involved in nutrient sensing and control of food intake. Given the anatomical proximity of this pathway to circuits for the hormone ghrelin, we investigated the potential role of the mTORC1/S6K pathway in(More)
as genetic tools for in vitro and in vivo silencing of ion channels Inaugural-Dissertation to obtain the academic degree Doctor rerum naturalium (Dr. rer. nat.) I would like to thank my group leader Dr. Inés Ibañez-Tallon for giving me the opportunity to work on this project, for her advices, support and supervision throughout the years.

At synaptic terminals, high voltage–activated Cav2.1 and Cav2.2 calcium channels have an essential and joint role in coupling the presynaptic action potential to neurotransmitter release. Here we show that membrane-tethered toxins allowed cell-autonomous blockade of each channel individually or simultaneously in mouse neurons in vivo. We report optimized(More)
