Objective: To examine the effect of sex on clinical response to triptans and to determine whether these differences are related to pharmacokinetics of triptans in men and women, we performed a systematic review and meta-analysis. Methods: We searched clinical trials distinguishing clinical response to or pharmacokinetic parameters of triptans between sexes in PubMed, MEDLINE, Cochrane Library, Embase and Web of Science up to Dec 12, 2019. Analysis was based on data extracted from published reports....

Objective: To determine the role of circulating endothelial microvesicles (EMV) and microvesicles (MV) of other origins on long-term cardiovascular outcomes after stroke, we measured them in a cohort of first-ever stroke patients and observed them for three years. Methods: In the PROSpective Cohort with Incident Stroke Berlin (PROSCIS-B), patients with first-ever ischemic stroke were followed for three years. The primary combined endpoint consisted of recurrent stroke, myocardial infarction, and all-cause mortality. Levels of EMV, leukocyte-derived...

Bladder cancer is one of the most commonly diagnosed and fatal malignancies of the urinary tract. Noncoding RNAs have been reported to be new biomarkers and effective treatment targets for bladder cancer. In the present study, we identified a novel bladder cancer-related circRNA-miRNA-mRNA network, the circ_0004463/miR-380-3p/FOXO1 axis. circ_0004463 is significantly downregulated, whereas miR-380-3p is upregulated in bladder carcinoma tissue samples and cells. circ_0004463 acts as a tumor suppressor by inhibiting bladder cancer cell proliferation. Genes...

Information processing in cortical neuronal networks relies on properly balanced excitatory and inhibitory neurotransmission. A ubiquitous motif for maintaining this balance is the somatostatin interneuron (SOM-IN) feedback microcircuit. Here, we investigate the modulation of this microcircuit by presynaptic GABAB receptors (GABABRs) in the rat hippocampus. Whole-cell recordings from SOM-INs reveal that both excitatory and inhibitory synaptic inputs are strongly inhibited by GABABRs, while optogenetic activation of the interneurons shows that their inhibitory output is also...

Middle East respiratory syndrome (MERS) coronavirus (MERS-CoV) causes a severe respiratory disease in humans. The MERS-CoV spike (S) glycoprotein mediates viral entry into target cells. For this, MERS-CoV S engages the host cell protein dipeptidyl peptidase 4 (DPP4, CD26) and the interface between MERS-CoV S and DPP4 has been resolved on the atomic level. Here, we asked whether naturally-occurring polymorphisms in DPP4, that alter amino acid residues required for MERS-CoV S binding, influence cellular entry...

Objective: To determine the nature and extent of minor neuropsychological deficits in patients with subjective cognitive decline (SCD) and their association with cerebrospinal fluid (CSF) biomarkers of Alzheimer’s disease (AD). Method: We analyzed data from n=449 cognitively normal participants (n=209 healthy controls, n=240 SCD patients) from an interim data release of the German Center for Neurodegenerative Diseases Longitudinal Cognitive Impairment and Dementia Study (DELCODE). An extensive neuropsychological test battery was applied at baseline for which...

The interferon-inducible myxovirus resistance B (MxB) protein has been reported to inhibit HIV-1 and herpesviruses by blocking the nuclear import of viral DNA. Here, we report a new antiviral mechanism in which MxB restricts the nuclear import of HIV-1 regulatory protein Rev, and as a result, diminishes Rev-dependent expression of HIV-1 Gag protein. Specifically, MxB disrupts the interaction of Rev with the nuclear transport receptor, transportin 1 (TNPO1). Supporting this, the TNPO1-independent Rev variants become...
