Postsynaptic [Ca2+]i has been proposed to play an important role in both synaptic plasticity and synaptic homeostasis. Postsynaptic Ca2+ signals appear to regulate synaptic transmission at the Drosophila larval NMJ; however, they have not been characterized at a NMJ. We were interested in examining the postsynaptic Ca2+ signals in this system and determining its influence on synaptic strength. The muscle Ca2+ transients were recorded by injecting the muscle fibers with Ca2+ indicators; discrete postsynaptic Ca2+ transients were observed along the NMJ during evoked and spontaneous transmitter release. The magnitude of the Ca2+ signals was correlated with synaptic efficacy, terminals producing …

The optic nerve and other central nervous system (CNS) axons tend to lose their capacity to regenerate following an injury in adult amniotes, but these axons are able to regenerate throughout life in anamniotes. The long-term goal of my study is to identify molecular mechanisms responsible for the retention of this regenerative capacity. Specifically, I will examine the role of the gene Suppressor of Cytokine Signaling 2 (SOCS2) in the successful regeneration of retinal ganglion cell (RGC) axons of the South African claw-toed frog, Xenopus laevis, after injury.

Coordinated synthesis and assembly of the cytoskeletal network contribute significantly to morphological changes during axon outgrowth. Previous studies demonstrated that heterogeneous ribonucleoprotein K (hnRNP K), an RNA binding protein, binds to the 3'-untranslated regions of all neurofilament triplet subunits, the most abundant components of the axonal cytoskeleton. These findings raised the hypothesis that hnRNP K post-transcriptionally mediates the coordinated expression of axonal cytoskeletal components. In my thesis, I test this hypothesis during both axonal development and regeneration.
