Protein Pathologies and Genetic Risk in Neurodegeneration
Parkinson’s disease (PD) and dementia with Lewy bodies (DLB) are progressive neurodegenerative diseases affecting movement and cognitive function in patients. These two diseases share a common pathology — aggregates bearing misfolded forms of the normally synaptic protein α-synuclein. While these diseases begin gradually, they progress relentlessly, and this progression of symptoms is associated with the accumulation of misfolded α-synuclein in more and more regions of the brain and the misfolding of additional proteins, including tau.
PD and DLB bear an additional commonality — the lack of disease-modifying treatments. Substantial evidence suggests that either disrupting the formation of protein pathologies or the transmission of pathology through the brain will result in stabilization, and perhaps improvement, of symptoms. Susceptibility to these diseases depends on several factors, including genetic background. Mutations in proteins like leucine-rich repeat kinase 2 (LRRK2) and glucocerebrosidase can predispose individuals to developing PD or DLB and targeting these proteins may provide therapeutic benefit for patients as well.
The Henderson Laboratory takes a two-pronged approach to addressing neurodegenerative disease. One approach is to understand what goes wrong in neurons and the brain to lead to neurodegeneration by probing disrupted cellular pathways, mapping how pathology spreads through the brain and investigating the impact of genetic risk factors on disease progression. The second approach is to use what we learn about these diseases to develop and evaluate potential therapeutic treatments. The laboratory utilizes primary neuron cultures to investigate cellular pathways disrupted in disease and screen therapeutic molecules. We also use animal models of disease to understand how pathological proteins spread through the brain and to evaluate the likely efficacy of top therapeutic candidates. It is the mission of the Henderson Laboratory to use rigorous scientific methods to understand neurodegenerative diseases and to leverage that knowledge to develop and evaluate treatments for these devastating diseases.

Biography
Michael Henderson is a neuroscientist whose focus is on the impact of protein pathologies and genetic risk factors on the development and progression of neurodegenerative diseases. He earned his B.Sc. in biological science from Florida State, followed by his Ph.D. in neuroscience from Yale University. He conducted his doctoral research in the lab of Dr. Sreeganga Chandra, and moved to the University of Pennsylvania for his postdoctoral fellowship in the Center for Neurodegenerative Disease Research with Drs. Virginia Lee and John Trojanowski. In 2020, Dr. Henderson joined Van Andel Institute’s Department of Neurodegenerative Science as an assistant professor. He was promoted to associate professor in 2024.
Dr. Henderson has made several seminal contributions to neurodegenerative disease research, including the identification of palmitoyl-protein thioesterase 1 as a protein aggregate in adult-onset neuronal ceroid lipofuscinosis, the demonstration that α-synuclein pathology spreads through anatomical connectivity in the brain, and the demonstration that glucocerebrosidase acts as a modulator of α-synuclein pathogenesis.
He has received several awards and honors, including the Graduate Research Fellowship from the National Science Foundation and the Ruth L. Kirschstein National Research Service Award for predoctoral research.

Parkinson's disease
Parkinson’s and Alzheimer’s are progressive, life-altering diseases that affect movement and cognitive function in individuals. The genes we are born with and the environment we grow up in influence our likelihood of developing disease but, in most cases, the cause of disease is unknown. What we know is that these diseases are characterized by the misfolding of normal brain proteins into aggregated forms that are toxic to cells. The Henderson Lab focuses on these aggregates, trying to understand how and why they form, and leveraging that knowledge to inform potential therapeutic interventions.
Some of the main questions we are currently addressing are:
Which cells are vulnerable to developing protein pathologies?
Aging is the major risk factor for all major neurodegenerative diseases. But not all of us develop disease. Even within a diseased brain, not all neurons are affected. What makes specific neuron types vulnerable? In addition to looking at single pathologies, we are leveraging brains and models with multiple pathologies (α-synuclein, tau) to understand how specific molecular programs determine how neurons develop pathology. We recently found that α-synuclein and tau almost always aggregate in different neurons, even when they are in the same brain, implicating selective cell type vulnerability.
How do neurons respond to protein aggregation?
One would think badly. No cell wants clumps of misfolded proteins and dysfunctional organelles clogging up their machinery. But they do the best they can, and neurons may survive years with aggregates. We recently identified a Lewy-Associated Molecular Dysfunction from Aggregates (LAMDA) signature associated with α-synuclein aggregates. This involves downregulation of homeostatic (mitochondria, synapse maintenance) pathways and upregulation of stress pathways (DNA damage repair, complement/cytokine). We aim to improve that cellular response, clear aggregates and improve neuronal function.
What brain region and network factors control pathology progression through the brain?
Unfortunately, symptoms for Parkinson’s and Alzheimer’s diseases are progressive. This insidious worsening of symptoms is tied to pathology becoming more extensively spread throughout the brain. We leverage brain mapping and network analysis to determine how pathology progresses through the brain, what underlies regional vulnerability to pathology, and what factors (genetic, environmental, molecular) influence pathology progression.
Can we leverage our knowledge to develop disease-modifying therapeutics?
A major goal for the lab is to turn our knowledge of disease into treatments. Our recent network analysis of pathology progression led us to molecular targets underlying vulnerability to developing pathology. From this, we identified a group of kinases that appear involved in aggregate formation and clearance. Inhibit those kinases and we reverse pathology and rescue neurons. We are now pushing to see if these kinases could be new therapeutic targets for Parkinson’s disease.
