Professional Summary
Free-living amoeba Naegleria
The long-term goal of our research is to identify drug targets in the TOR (target of rapamycin) kinase signaling axis and to develop pharmacological agents against Naegleria fowleri. N. fowleri is a pathogenic free-living amoeba that causes rare (151 reported cases as of 2020 in the US) but highly fatal (greater than 97%) primary meningoencephalitis in the central nervous system. The thermophilic amoeba lives in warm freshwater in the southern states (e.g., Texas and Florida) and gains access to the cerebrum when contaminated water enters the nasal cavity. The onset of symptoms such as headache and nausea starts within a week of infection, and it only takes another week for a patient to succumb to the disease.
Biologically, Naegleria species have a fascinating and unique feature: they can transform into three different morphological stages depending on environmental conditions. The trophozoite (amoeboid) is the feeding stage of the life cycle and is mitotically active, while the cyst form is metabolically inert. The third form is flagellate, having a pair of flagella with which Naegleria swims away from the unfavorable environment. Using the non-pathogenic Naegleria gruberi (NEG-M strain, ATCC#30224) as the model organism, we are currently investigating the TOR-mediated regulatory mechanism of encystment.
Angiogenesis
The dynamic transformation of cellular morphology during the locomotive process is a fascinating phenomenon. Endothelial cells, the essential component of blood vessels covering the innermost surface of the tubular structure, undergo such morphogenesis during development and certain pathological conditions, including retinopathies, cancers, and arthritis. During the transformation process, endothelial cells become active in proliferation (an increase in the number of cells) and migration, the combination of which leads to the formation of new vessels (angiogenesis). Our research interest is to investigate the molecular signals within the endothelial cell that govern the migratory aspect of angiogenesis, ultimately aiming to identify pharmacological means to intervene the unwanted angiogenesis in pathological conditions.
