Dopamine-Beta-Hydroxylase And Norepinephrine Transporter Immunoreactivity In Rat Taste Buds, Jenna Ashley Walton
Dopamine-Beta-Hydroxylase And Norepinephrine Transporter Immunoreactivity In Rat Taste Buds, Jenna Ashley Walton
Electronic Theses and Dissertations
Of the handful of neurotransmitters modulating taste response, norepinephrine (NE) may be the least understood. Although the physiological role of NE has been tested, it is still unclear whether the rat taste bud may serve as an endogenous source of neurotransmitter or if it must be taken up from outside the taste bud. Immunocytochemical analysis of DBH has shown that DBH–LIR is present in taste cells of the rat circumvallate papillae. Specifically, DBH–LIR is present in a subset of Type II taste cells. Nearly all (98%) DBH–LIR cells express PLCβ2–LIR, and about half (41%) of PLCβ2–LIR cells express DBH–LIR. DBH–LIR …

Role Of Pro-Apoptotic Bcl2-Homology-3 Domain (Bh3)-Only Proteins In The Mutant Sod1 Mouse Model Of Als, Anna George Andrianakos
Electronic Theses and Dissertations
Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease involving rapid degeneration of motor neurons in the spinal cord and retraction of their axonal projections to the neuromuscular junctions. Several known mutations linked to some familial cases of ALS have been linked to mutations in Cu/Zn superoxide dismutase (SOD1), resulting in mitochondrial oxidative stress and intrinsic apoptosis. Transgenic mice expressing a G93A mutant of SOD1 provide an in vivo model to investigate motor neuron death during disease progression. The principal regulators of intrinsic apoptosis are the Bcl-2 family proteins. While some members of this family are pro-survival, the Bcl-2 homology-3 …
