Morgan Coburn recognized as “Most Promising Future Faculty”

Congratulations to Angeline Duke and Morgan Coburn for winning the 2021 Most Promising Future Faculty Award! The Most Promising Future Faculty Award recognizes graduate students who show great promise through their effectiveness as instructors or teaching assistants.

Morgan Coburn is currently a Ph.D. candidate in the Department of Neurobiology and Behavior. Her teaching experience is off the charts, having served in ten different teaching capacities. Her research focuses on the action of microglia, the innate immune cell of the brain, and their role in Alzheimer’s disease. Morgan hopes to find a cure for one of society’s most heartbreaking diseases and she wants to give back and teach full time one day.

Congratulation once again to Morgan Coburn for winning the 2021 Most Promising Future Faculty Award!

Amanda McQuade awarded at 12th Annual Emerging Scientists Symposium

This prize is awarded in honor of Dr. Carl W. Cotman’s legacy in scientific accomplishments throughout his Directorship of the Institute for Memory Impairments and Neurological Disorders and the development of the health sciences at UCI.  Dr. Cotman’s passion and longstanding interest in the brain have fostered research within the Institute and on the UCI campus throughout the years.  The recipient of this award is selected from those who have excelled in their studies on memory impairments and neurological disorders and have helped to advance the mission of the Institute.  You should be proud of your accomplishments and for having received this award.

Amanda McQuade awarded the Junior Faculty Award

Modeling Alzheimer’s risk using human TREM2-knockout microglia

Amanda McQuade from Dr. Mathew Blurton-Jones’s lab discusses her protocol for differentiating microglia from induced pluripotent stem cells (iPSCs) and the use of these microglia in vivo and in vitro to uncover the mechanisms of immune activation and neurodegeneration in Alzheimer’s disease. Based on the 2020 Nature Communications paper “Gene Expression and Functional Deficits Underlie TREM2-Knockout Microglia Responses in Human Models of Alzheimer’s Disease“.

Morgan Coburn Awarded Prestigious Pedagogical Fellowship

Pedagogical Fellows are a group of productive apprentice scholars who also have an interest in providing superlative instruction in their roles as Teaching Assistants.

Fellows are selected through a competitive process based on teaching evaluations, letters of recommendation, and demonstrated interest in pedagogy. They commit to additional coursework and training in order to learn more about pedagogy in higher education, educational trends, and how to better prepare for the academic job market. They also provide an important service to the academic community by designing and implementing discipline-specific training for new TAs in their departments and Schools.

With their skills, experience, and increased self-confidence, the Pedagogical Fellows have been successful in securing professorial and professional positions in which they are interested.

Congratulations Morgan Coburn!

Examining how the TREM2 R47H mutation effects microglial lipid content and the interactions between human microglia and AD pathology within the brain

Christel Claes, PhDAlzheimer’s disease is the most common type of dementia that causes problems with memory, thinking and behavior, and so far we don’t understand this disease well enough to find a cure to help these patients. In our proposal, we want to increase our understanding of this disease by studying microglia, the resident immune cells of the brain, and a gene called TREM2 which when mutated can significantly increase the risk of developing Alzheimer’s disease. Our recent studies show that when we transplant healthy human stem cell-derived microglia carrying a normal version of TREM2 into the brain of Alzheimer mice that develop amyloid plaques (a main characteristic of this disease), human microglia near the plaques show similarities to peripheral ‘foam cells’, which are immune cells filled with lipids and linked with another disease called “atherosclerosis”. As TREM2 is a lipid-sensor expressed by microglia, we now want to study the lipid content and the reaction of human microglia that carry the TREM2 R47H mutation to amyloid plaques in this specialized mouse model, to greatly improve our understanding of how this mutation can increase Alzheimer’s risk, which will in turn allow scientists to find treatments that increase the functionality of microglia to protect our brain from the damage caused by these amyloid plaques.

UCI MIND Researchers Use Human Stem Cell Models To Understand Immunity In Alzheimer’s Disease

Amanda McQuade, a graduate student in Mathew Blurton-Jones’ lab at UCI MIND, discusses findings from their new study using induced pluripotent stem cells (iPSC), donated from participants at the UCI Alzheimer’s Disease Research Center, and CRISPR gene editing to improve understanding of the role of immunity in Alzheimer’s disease.

Gene expression and functional deficits underlie TREM2-knockout microglia responses in human models of Alzheimer’s disease

The discovery of TREM2 as a myeloid-specific Alzheimer’s disease (AD) risk gene has accelerated research into the role of microglia in AD. While TREM2 mouse models have provided critical insight, the normal and disease-associated functions of TREM2 in human microglia remain unclear. To examine this question, we profile microglia differentiated from isogenic, CRISPR-modified TREM2-knockout induced pluripotent stem cell (iPSC) lines. By combining transcriptomic and functional analyses with a chimeric AD mouse model, we find that TREM2 deletion reduces microglial survival, impairs phagocytosis of key substrates including APOE, and inhibits SDF-1α/CXCR4-mediated chemotaxis, culminating in an impaired response to beta-amyloid plaques in vivo. Single-cell sequencing of xenotransplanted human microglia further highlights a loss of disease-associated microglial (DAM) responses in human TREM2 knockout microglia that we validate by flow cytometry and immunohistochemistry. Taken together, these studies reveal both conserved and novel aspects of human TREM2 biology that likely play critical roles in the development and progression of AD.
