Congratulations to Dr. Breslin!

We would like to congratulate Dr. Jerome Breslin, who has been elected as President-Elect of the Microcirculatory Society. The link to the Microcirculatory Society’s website is listed here for reference: . Dr. Breslin will lead the Microcirculatory Society in its mission to “actively encourage and promote all forms of innovative research and teaching, leading to an increase in understanding of microcirculatory function in health and disease.” This is a prestigious honor and we are very proud to have Dr. Breslin on our team. Congratulations!

Congratulations to Dr. Totary-Jain!

Dr. Hana Totary-Jain has been selected as the winner of the 2020 Alan T. Hirsch, MD Mid-Career Award in Vascular Medicine. Dr. Totary-Jain is an Associate Professor in the Department of Molecular Pharmacology and Physiology and her lab focuses on non-coding RNAs and their regulatory role in cardiovascular diseases. The award was presented during the AHA Vascular Discovery: From Genes to Medicine Scientific Sessions 2020.

The title of her talk: "Design and delivery of microRNA switches to treat cardiovascular diseases".

Description: 3D confocal image from whole mount of mouse wire-injured femoral arteries 48 hours after a single intravenous injection of niRFP mRNA-p5RHH nanoparticle.

β-Arrestin2 oligomers impair the clearance of pathological tau and increase tau aggregates

Multiple G protein-coupled receptors (GPCRs) are targets in the treatment of dementia, and the arrestins are common to their signaling. β-Arrestin2 was significantly increased in brains of patients with frontotemporal lobar degeneration (FTLD-tau), a disease second to Alzheimer’s as a cause of dementia. Genetic loss and overexpression experiments using genetically encoded reporters and defined mutant constructs in vitro, and in cell lines, primary neurons, and tau P301S mice crossed with β-arrestin2−/− mice, show that β-arrestin2 stabilizes pathogenic tau and promotes tau aggregation.

Identification and Characterization of Novel Bronchodilator Agonists Acting at Human Airway Smooth Muscle Cell TAS2R5

Bitter taste receptors (TAS2Rs) are recognized asbeing expressed on multiple cell types and organs, includinghuman airway smooth muscle (HASM) cells, where agonistspromote significant relaxation to constrictive stimuli. Thus, theHASM TAS2Rs have been targeted as novel bronchodilators forthe treatment of asthma and other obstructive lung diseases. These studies revealed critical structural requirements for favorable potencies andefficacies for a potentialfirst-in-class bronchodilator targeting TAS2R5 of the airway.

Hippocampal and Prefrontal Cortical Brain Tissue Levels of Irisin and GDF15 Receptor Subunits in Children

Cold-stress hormones (CSHs) stimulate thermogenesis and have direct neuroprotective effects on the brain. The obligatory receptor components of two new CSHs (irisin and growth differentiation factor-15 [GDF15]) were recently discovered.
