An Analysis Of The Involvement Of Toll Receptors In Cell Movements During The Elongation Of Tribolium Castaneum, Kathryn Russell

Senior Theses and Projects

Elongation of the anterior/posterior body axis is a critical part of embryonic development. Cell movements are known to play a significant role in embryo elongation in the red flour beetle Tribolium castaneum. In the arthropod model organism, Drosophila, Toll receptors have a demonstrated role in the elongation of the embryo by driving convergent extension, in which rows of cells intercalate with one another in one direction to extend tissue in the other. In Drosophila, Toll receptors are a link between anterior-posterior patterning genes expressed in discrete stripes and effector molecules causing cell movements. This cell movement is caused …
