Yale researchers have found that the disease’s debilitating symptoms may be the result of swelling caused by amyloid plaques in the brain.

The causes of dementia remain largely unknown to medicine. Scientists and researchers are working hard to connect what is known with gaps in treatment, and illuminating those mysteries that have yet to be resolved.

Nelson Perez Catalan discovered he was interested in pursuing science while working at a student job at the University of Oregon cleaning glass in the labs. He found himself drawn to research around the brain, and thought about pursuing an MD/PhD, but there was no medical school at his university and as a transplant from Chile, he says much of the U.S. college process was mystifying to him. Then he learned about PATHS, or Program to Advance Training in Health and Sciences at Yale School of Medicine.

The purpose of this Yale mini-symposium is to highlight the huge unmet clinical need to understand the pathophysiology of small vessel disease to inform future therapeutic efforts to reduce the burden of this illness due to cognitive impairment and dementia. In particular the cellular and molecular mechanisms that underlie diffuse white matter disease and small vessel disease in the brain, the relationships between them, and how they may contribute to cognitive impairment and dementia.

Myelin acts as insulation for millions of brain cells, allowing for swift and efficient transmission of signals across brain regions. Despite its crucial role, little is known about how stable this structure is in the adult brain and what impact aging has on its maintenance. Yale neurologists Robert Hill, Alice Li, and Jaime Grutzendler devised techniques to track and precisely image myelin throughout the lifetime of the mouse. They discovered that myelin continues to form and restructure in the adult brain — indicating the potential for lifelong change. They also learned that during aging, myelin begins to deteriorate and myelin debris accumulate over time.

New research bolsters the case that brain-derived microglia need TREM2 to essentially wall off amyloid plaques, but exactly how they do that remains up for debate. As reported in the May 18 Neuron, scientists led by Jaime Grutzendler at Yale University, New Haven, Connecticut, used confocal and super-resolution microscopy to show that TREM2-positive microglia surround and encase amyloid fibrils, protecting neurons in the process. Yet TREM2 itself appears to lend little support to phagocytosis of Aβ. The technical caliber of the work and the quality of the microscopy led researchers in the AD field to call the study “stunning.” It comes on the heels of another paper, in the April 18 Journal of Experimental Medicine, which suggests the microglia that surround plaques are brain-derived, not peripheral myeloid cells as others had suggested previously.
