Stem Cell-derived Neurons Facilitate Study of Alzheimer’s Disease Mechanisms, Treatments

3D rendering of pluripotent stem cells

Tracy Young-Pearse, PhD, Valentina Lagomarsino, Richard V. Pearse II, PhD, and colleagues have created a system that fills the gap between autopsy studies and genetic studies. They’ve shown that neurons derived from induced pluripotent stem cells (iPSCs) reflect molecular mechanisms underlying late-onset AD.

“Self-tunable” Engineered Yeast Probiotics May Allow Precision Treatment of IBD

Francisco J. Quintana, PhD, Cristina Gutiérrez-Vázquez, PhD, and colleagues engineered yeasts that generate an immunosuppressive molecule in direct proportion to the amount of a pro-inflammatory metabolite produced in the inflamed gut. They describe their new treatment platform and the results.

What Are the Best Treatment Options for Epilepsy That Doesn’t Respond to Medications?

3-D segmented coronal MRI demonstrating bilateral deep brain stimulation.

Physicians at the Brigham are developing various treatments to improve seizure control for patients with epilepsy. As Garth Rees Cosgrove, MD, director of epilepsy and functional neurosurgery, explains, these therapies require a great deal of diagnostic and surgical expertise along with the latest cutting-edge tools.

Neural Circuit for Spirituality and Religiosity Identified

Human Brain Scan X-Rays

By using a newer technique called lesion network mapping, Michael Ferguson, PhD, Michael D. Fox, MD, PhD, of the Center for Brain Circuit Therapeutics at Brigham and Women’s Hospital, and colleagues have identified a specific brain circuit that seems to be a neural substrate for spirituality and religiosity.

Factors That Warrant Screening for Thoracolumbar Spine Fracture After TBI

To determine when additional imaging may be advisable, Hasan A. Zaidi, MD, and Blake M. Hauser of the Computational Neurosurgical Outcomes Center in the Department of Neurosurgery at Brigham and Women’s Hospital, and colleagues identified common risk factors for thoracic and lumbar spinal fractures in TBI.
