Antibodies To Heterogenous Nuclear Ribonucleoprotein A1 Penetrate Neurons Leading To Multiple Downstream Effects Resulting In Neurodegeneration, Joshua Nathan Douglas
Antibodies To Heterogenous Nuclear Ribonucleoprotein A1 Penetrate Neurons Leading To Multiple Downstream Effects Resulting In Neurodegeneration, Joshua Nathan Douglas
Theses and Dissertations (ETD)
Multiple sclerosis (MS) is the most common demyelinating disorder of the central nervous system. MS is believed to occur in genetically susceptible individuals due to an unknown environmental stimulus. MS patients produce autoantibodies to heterogenous nuclear ribonuclearprotein A1 (hnRNP A1), an RNA binding protein (RBP) highly expressed in neurons. hnRNP A1 functions in pre-mRNA splicing, mRNA trafficking, and translation. Furthermore, the anti-hnRNP A1 antibodies are specific to a N-terminal region termed ‘M9’ which serves as a nuclear export sequence/nuclear localization sequence (NES/NLS) responsible for nuclear/cytoplasmic transport of the protein. In this manuscript we will provide data revealing that anti-hnRNP A1 …
Tetrahydroisoquinoline Neurotoxins In Parkinson Disease, Michael G. Decuypere
Tetrahydroisoquinoline Neurotoxins In Parkinson Disease, Michael G. Decuypere
Theses and Dissertations (ETD)
The goal of this dissertation work was to (1) determine the distribution of several tetrahydroisoquinoline (TIQ) derivatives in rodent, normal human and Parkinson disease (PD) brain, (2) quantify the levels of these TIQ derivatives in common food sources in an effort to link specific food intake patterns with the development of PD and (3) examine the neurotoxicity of select TIQ derivatives in human dopaminergic cell culture. The TIQs are a family of monoamine alkaloids that share structural homology with 1-methyl-4-phenyl-1,2,3,6-tetrahyrdropyridine (MPTP), can be formed from dopamine or its oxidized metabolites and may be involved in the pathogenesis of monoaminergic cell …
H5n1 Influenza Virus Induces A Parkinsonian Pathology, Haeman Jang
H5n1 Influenza Virus Induces A Parkinsonian Pathology, Haeman Jang
Theses and Dissertations (ETD)
The greatest threat for an influenza pandemic at this time is posed by the highly pathogenic H5N1 avian influenza virus. To date, 63% of the 436 known human cases of H5N1 infection have proven fatal. Animals infected by H5N1 viruses have demonstrated acute neurological signs ranging from mild encephalitis to motor disturbances and coma. However, no studies have examined the longer-term neurologic consequences of H5N1 infection. We show that this virus travels from the peripheral nervous system into the central nervous system (CNS) to higher levels of the neuroaxis, using C57BL/6J mice that are infected by the A/VN/1203/04 H5N1 virus …
