Regulation Of Polarized Protein Transport To Axons, Dendrites, And Sensory Cilia In Caeborhabditis Elegans Neurons, Tapan Apurva Maniar
Student Theses and Dissertations
Neurons are highly polarized cells, capable of receiving, processing and transmitting information, with the help of their specialized domains, an axon and one or more dendrites. The molecular dissimilarities between these domains are critical for neuronal function, and are a result of asymmetric trafficking of a large number of cellular components including ion channels, neurotransmitter receptors, synaptic vesicles, and signaling proteins. Yet, despite the significance of asymmetric protein transport in neuronal polarity, the molecules and mechanisms that direct polarized transport to axons, dendrites and cilia in neurons are only partly understood. In this thesis, I describe my effort at understanding …

In the course of metazoan embryonic and post-embryonic development, more cells are generated than exist in the mature organism, and these cells are deleted by the process of programmed cell death. In addition, cells can be pushed toward death when they accumulate genetic errors, are virally-infected or are otherwise deemed potentially-harmful to the overall organism. Caenorhabditis elegans has proved to be an excellent model system for elucidating the genetic underpinnings of cell death, and research has shown that the core machinery, made up of the egl-1, ced-9, ced-4 and ced-3 genes, is conserved across metazoans, and their homologues are crucial …

The Long-Rage Directional Behavior Of The Nematode C. Elegans, Margherita Peliti
Student Theses and Dissertations
Like any mobile organism, C. elegans relies on sensory cues to find food. In the absence of such cues, animals might display defined search patterns or other stereotyped behavior. The motion of C. elegans has previously been characterized as a sinusoid whose direction can be modulated by gradual steering or by sharp turns, reversals and omega bends. However, such a fine-grained behavioral description does not by itself predict the longrange features of the animals’ pattern of movement. Using large (24 cm x 24 cm) Petri dishes, we characterized the movement pattern of C. elegans in the absence of stimuli. To …
