Insect Host Seeking: Investigations into the Molecular Mechanisms of Chemosensation
… of two distinct pathways involved in insect chemosensation. The atypical odorant receptor gene, Or83b, is co-expressed with other ORs in most olfactory sensory neurons (OSNs) of the Drosophila antenna. OR83b acts as a generic heterodimeric partner for other ORs coupling them to the ciliary …

The Intricate Molecular Landscape of Insect Chemosensation: The Sensory Neuron Membrane Protein Gene Family
<p>SNMPs (Sensory Neuron Membrane Proteins) are members of a gene family characterized by human CD36. This family has diverse functions including transportation of fatty acids and interactions with other proteins in cell:cell recognition. SNMPs are membrane proteins observed to associate with …

Effects of sodium chloride and sodium gluconate concentration on hydration behavior and water transport in the red-spotted toad, Bufo punctatus
… well as epithelial sodium channels function in chemosensation across the amphibian skin and that the ventral skin and the feet may have different roles in chemosensation.

Studies on Host-Seeking Behavior and Differential Chemosensory Gene Expression in Above- and Below-ground Culex Pipiens
… was not correlated with host preference. Chemosensation drives host-seeking behaviors in female mosquitoes, which led me to quantify the expression of two chemosensory genes: odorant binding proteins (OBPs) 2 and 12. Both OBPs were more highly expressed in the heads of human-preferring …

Understanding the role of human microbiota on sensory perception
… amongst the most influential. Analogously, chemosensation is affected by a myriad of determinants, and this warrants the commonly observed large variation in how tastes and smells are perceived among individuals. Given how such variability intimately relates to dietary habits, deciphering …

I. Synthesis of Ascarosides for Chemical Biology Studies in Caenorhabditis elegans, II. A Photochemical Approach to Delavayine, and III. Remote Hydroxylation by Radical Translocation and Polar Crossover
… elegans developmental and reproductive assays. Chemosensation of ascarosides results in downregulation of important signaling pathways, which are conserved in higher organisms, and our studies provide data on the effects of these processes. We hypothesize that knowledge gained from these studies …

Diet, adaptation and the evolution of assortative mating in Ceratitis capitata
… associated with oxidative phosphorylation and chemosensation. Taken together, the results of this research present a novel example of how divergent ecological selection pressure can lead to the evolution of sexual isolation in experimental populations.

The Genetics Of Mosquito Heat-Seeking Behavior
… playing conserved roles in thermoregulation and chemosensation, is important for thermotactic tuning of heat-seeking. AaegTRPA1-/- mutant mosquitoes fail to avoid high-temperature stimuli, and do not distinguish between thermal targets that resemble hosts and those that are inappropriately …

I. Synthesis of Ascarosides for Biological Evaluation and II. Development of Visible Light-Promoted Selenofunctionalization and Grafting of Aryl Iodides
… Dauer formation is triggered by the nematode’s chemosensation of the dauer pheromone, consisting of a group of previously-isolated ascarosides. These compounds differ in chain length, saturation, terminal functionality of side chain, ω vs. ω-1 oxygenation and presence of an indole-3-carboxyl …

Cells that Kill: The Chemosensory Cell Types of Aedes aegypti Mosquitoes
… or behavior. For my doctoral work, I studied chemosensation in the Aedes aegypti mosquito, which can detect cues including human odor, carbon dioxide, and insect repellents. Mosquitoes are human's deadliest predator, causing 700,000 deaths every year through the transmission of malaria …

Transcriptomic and proteomic analysis of Ascaris suum larvae during their hepato-tracheal migration
… for each larval stage, the metabolic changes and chemosensation pathways active in the larvae and, finally, the expression of potential molecular mimicry candidates. Illumina RNA sequencing of the A. suum infective-stage, liver-stage, lung-stage and intestinal-stage larvae resulted in 95,463,423 …

Dining in the Dark ATP Sensing in the Female Aedes Aegypti Mosquito
<p>Blood feeding is fundamental for female <em>Aedes aegypti </em>mosquitoes, which require this protein-rich meal for egg development. After being attracted to a human host by sensory cues such as body odor, body heat, and carbon dioxide exhaled in human breath, the mosquito lands and probes under …

Concentration-dependent recruitment of mammalian odorant receptors
<p>Deciphering natural odor plumes with dynamic changes in odor concentrations presents a common challenge to all animals. A fundamental challenge in studying the organization principles of the olfactory system to encode odor concentration information is the lack of comprehensively identified sets …
