Welcome to the Pluvinage Lab!

Our goal is to improve the lives of patients with neurological diseases. We do this by exploring undiagnosed autoimmunity in rare mystery cases and common neurodegenerative conditions alike. How does the immune system regulate cognitive function, and how can we modulate it to promote healthy brain aging?

Research Focus

Autoantibody Discovery and Mechanism

Autoimmune encephalitis (AE) is a rare condition where antibodies target brain antigens leading to severe cognitive dysfunction, but the identity of these antibodies is often unknown. We are developing functional genomic and computational tools to discover the source, target, and mechanism of new pathogenic autoantibodies.

Antigen-Specific Treatments

Current treatments for autoimmune neurological diseases are nonspecific, ineffective, and/or neurotoxic. How can we eliminate pathogenic autoantibodies while leaving the rest of the immune system intact?

Autoimmune Regulation of Cognition

Beyond AE, comorbid autoantibodies are enriched in several neurodegenerative conditions. We investigate the hypothesis that pathogenic autoantibodies exacerbate dementia, and, even more exploratory, that protective autoantibodies exist in cognitively resilient individuals.

Team

Core Investigator

John Pluvinage, MD, PhD

John is an Assistant Professor of Neurology at the University of California, San Francisco. He received his BS in Bioengineering and then MD and PhD from Stanford, investigating mechanisms of microglial aging and rejuvenation. He completed his clinical Neurology residency and postdoctoral fellowship at UCSF focusing on the overlap between autoimmunity and neurodegeneration. His research has been recognized by a Burroughs Wellcome Fund Career Award for Medical Scientists, a NIH K08 Career Development Award, and the American Academy of Neurology’s S. Weir Mitchell Award.

Current Members

Postdog

Berkeley

Berkeley received his BA in human psychology from San Jose State University before completing his PhD on sleep electrophysiology from Stanfur. In his free time, he enjoys chasing squirrels and chewing on milk cartons.

Staff Research Associate

Bonny Alvarenga

Bonny is a Staff Research Associate at the Arc Institute. She received her BA in Molecular and Cell Biology with a focus in Immunology and Pathogenesis from UC Berkeley. Previously, she conducted autoantibody discovery in the Wilson Lab at UCSF and contributed to early drug discovery efforts at Arcus Biosciences. In the Pluvinage Lab, Bonny will be focusing on further autoantibody discovery efforts related to neurodegeneration. She enjoys crocheting and hiking national parks in her free time.

Rotating Graduate Student

Richard Dela Rosa

Richard is a 1st year Biology PhD student from Stanford. He received his BS in Life Sciences from Ateneo de Manila University (Philippines). He completed his MSc in Molecular Mechanisms at Radboud University (Netherlands), including an internship at Boston Children's Hospital where he developed VHH tools to dissect the basic mechanisms of E2 ubiquitin-conjugating enzymes. Before starting graduate school, he worked at Cradle, a techbio start-up based in the Netherlands, to build high-throughput workflows to characterize and optimize antibody fragments. Outside of work, he enjoys painting, hiking, and reading.
