Inspiratory Off-Switch Mediated by Optogenetic Activation of Inhibitory Neurons in the preBötzinger Complex In Vivo

Abstract: The role of inhibitory neurons in the respiratory network is a matter of ongoing debate. Conflicting and contradicting results are manifold and the question whether inhibitory neurons are essential for the generation of the respiratory rhythm as such is controversial. Inhibitory neurons are required in pulmonary reflexes for adapting the activity of the central […]

Pharmacological treatment with mirtazapine rescues cortical atrophy and respiratory deficits in MeCP2 null mice

Loss of MeCP2 (Methyl CpG binding protein 2) in Rett syndrome (RTT) causes brain weight decrease, shrinkage of the cortex with reduced dendritic arborization, behavioral abnormalities, seizures and cardio-respiratory complications. The observed monoamine neurotransmitters reduction in RTT suggested antidepressants as a possible therapy. We treated MeCP2-null mice from postnatal-day 28 for two weeks with desipramine, […]

Development and evaluation of murine lung-specific disease models for Pseudomonas aeruginosa applicable to therapeutic testing.

Pseudomonas aeruginosa is an opportunistic bacterial pathogen capable of causing a wide range of disease manifestations, including severe bacterial pneumonia. Recently, clinics have reported a rise in nosocomial infections with multidrug resistant (MDR) species, including MDR strains of P. aeruginosa. In order to quickly evaluate the efficacy of new therapeutics for MDR infections, highly reproducible […]

Intravital live cell triggered imaging system reveals monocyte patrolling and macrophage migration in atherosclerotic arteries

Intravital multiphoton imaging of arteries is technically challenging because the artery expands with every heartbeat, causing severe motion artifacts. To study leukocyte activity in atherosclerosis, we developed the intravital live cell triggered imaging system (ILTIS). This system implements cardiac triggered acquisition as well as frame selection and image registration algorithms to produce stable movies of […]

The circadian body temperature rhythm of Djungarian Hamsters (Phodopus sungorus) revealing different circadian phenotypes

Abstract: Djungarian hamsters (Phodopus sungorus) of our breeding stock show three rhythmic phenotypes: wild type (WT) animals which start their activity shortly after “lights-off” and are active until “lights-on”; delayed activity onset (DAO) hamsters whose activity onset is delayed after “lights-off” but activity offset coincides with “lights-on”; and arrhythmic hamsters (AR) that are episodically active […]
