Understanding Chemotaxis in the Nematode Caenorhabditis elegans: From Molecules to Behavior
How animal behavior is controlled at the molecular and cellular levels is still largely mysterious. Here, I document my studies on the mechanisms controlling a simple behavior--chemotaxis--in the nematode worm Caenorhabditis elegans. My work focuses on a pair of amphid sensory neurons at the head …

Cracking the Odor Code: Molecular and Cellular Deconstruction of the Olfactory Circuit of Drosophila Larvae
… by which the olfactory system processes behaviorally relevant sensory stimuli. The numerically reduced larval olfactory system relieves the formidable molecular and cellular complexity found in other organisms. This thesis presents a study in four parts that investigates molecular and …

Characterization of the Sinorhizobum Meliloti Chotaxis System
… 2 focuses on the deviation of the S. meliloti chemotaxis system from the enteric paradigm. Quantitative immunoblots determined the cellular amounts of chemotaxis proteins. Overall, chemotaxis protein levels were approximately 10-fold lower in S. meliloti compared to B. subtilis and E. coli. …

Quantification of molecular-level events at nanoparticle-biological interfaces
… microenvironments and thus to influence the cell chemotaxis behavior. µ-Slide chemotaxis assay was employed to characterize and compare the THP-1 cells migration in the gradient of monocyte chemoattractant protein-1 (MCP-1) upon exposure to gold nanoparticles with four different surface …

The Role of Drosophila Odorant Receptors in Odor Coding
… contribution of several ORs to olfactory-guided behavior. We compiled near-complete maps of OR-specific neuronal projections to the antennal lobe glomeruli of adult and larval fly brains. We analyzed expression profiles of 42 ORs, 31 of which are expressed in the adult and 21 in the larva, with …
