Research

The overall goal of our research at the Center for Neurotherapeutics is to understand how cellular functions are modulated by signaling molecules under physiological conditions and in complex neurological diseases. With the better understanding of underlying molecular mechanisms of disease progression, we develop and investigate next generation neurotherapeutics. The current focus is on small G-protein signaling, with the emphasis on several classes of Ras superfamily proteins. We employ a combination of modern technologies in chemical biology, computer modeling, biochemistry, pharmacology, cellular imaging, and mouse genetics to investigate the deregulation of small GTPases of Rho, Rab, and Arf subfamilies in Alzheimer’s disease and related dementias (ADRD) as well as amyotrophic lateral sclerosis (ALS). These investigations are built on the following areas of researches:
(I). Small GTPase expression and functions are dysregulated in a spatial and temporal manner in diseased brain. This is established by a series of studies employing confocal and super-resolution fluorescence imaging, computational analysis with AI/ML toolboxes, and transcriptomic and barcoding technologies. 
(II). The spatial and temporal dysregulation supports novel concept of homeostatic modulation as a therapeutic paradigm. Our translational research, leveraged by the pioneering discovery of multifunctional small molecule homeostatic modulators (HMs) of small GTPases, applies CADD (Schrödinger software), biochemical (Biacore 1S+ SPR and activity-based ELISA) and pre-clinical (Cell-based assay and mouse genetics) validation to target ADRD and ALS.
