Biosketch

My laboratory is interested in how extracellular matrix proteins, transmembrane receptors, and cytoskeletal adapters work together to specify tissue architecture. We primarily use C. elegans as a model organism to study the nematode orthologs of conserved extracellular proteins that are defective in human diseases. In the past we have discovered hemicentin and identified functional interactions between hemicentin and fibulin. These two proteins have been implicated in Age-related Macular Degeneration (AMD), a common human disease that is characterized by progressive degeneration of sensory neurons, called photoreceptors, in the retina. Currently, we are studying how interactions between complement factor H (a secreted protein that is frequently mutated in ARMD patients), transmembrane, and cytoskeletal proteins affect sensory neuron function in C. elegans and asking whether these interactions are conserved in vertebrate photoreceptors.

Where is complement factor H (CFH) found in C. elegans?

Age-related Macular Degeneration (AMD) is the leading cause of blindness among the elderly in the developed world. However the mechanism of AMD pathogenesis is poorly understood. Mutations in CFH increase risk for AMD 6-20 fold. The canonical function of CFH is to inhibit inflammation and cytolysis caused by activation of the alternative complement pathway of the innate immune system. Therfore, current thinking suggests that the disease mechanism is likely a result of an increase in inflammation in the retina. However our findings suggest a direct role for CFH in sensory neuron function. Using CRISPR-Cas9, we have constructed a functional fusion between CFH and green fluorescent protein (GFP), enabling us to monitor CFH-GFP localization in live animals during development. CFH-GFP accumulates at the ciliated tips of sensory neurons involved in mechanosensation. Based on this and other data (see Acker et al., 2021), we believe that AMD may result directly from a defect in sensory neuron (i.e. photoreceptor) function.

Our current focus is on using molecular, genetic and biochemical tools to identify the functional significance of CFH on sensory neuron cell surfaces and to identify cell surface receptors and other extracellular proteins that functionally interact with CFH. 

The long-term goal is to understand the mechanism of AMD pathogenesis and to develop therapies to inhibit this mechanism.
