Abstract: The present invention relates to identification and uses of biomarkers for neurodegenerative disease, including Alzheimer's disease, and the related diseases. More specifically, the present invention relates to the identification of protein biomarkers useful for the screening, diagnosis, and differentiation of Alzheimer's disease from Parkinson's disease, other neurodegenerative diseases, and normal controls, and in the monitoring of Alzheimer's disease severity and disease mechanisms in patients.

Abstract: The present invention relates to a Complement Factor H protein as a biomarker for neurodegenerative disease, including Parkinson's disease, and the related diseases. More specifically, the present invention relates to the identification of a Complement Factor H protein, useful for the screening, diagnosis, and differentiation between neurodegenerative diseases.

Abstract: The present invention relates to an Apolipoprotein E3 protein as a biomarker for neurodegenerative disease, including Parkinson's disease, and the related diseases. More specifically, the present invention relates to the identification of an Apolipoprotein E3 protein, useful for the screening, diagnosis, and differentiation of Parkinson's disease from Alzheimer's disease, other neurodegenerative diseases, and normal controls.

Abstract: The present invention is directed to overproduction of nitric oxide synthase (NOS) in a prokaryote. More particularly, the invention involves overexpression of functional neuronal NOS in a protease-deficient strain of Escherichia coli, utilizing a pCW vector under the control of the tac promotor. The invention further involves co-expression of the protein with folding agonists, or chaperonins. The enzyme produced is complete with heme and flavins, and may be activated by incubation with tetrahydrobiopterin. It may be isolated as a predominantly high spin heme protein that demonstrates spectral properties which are identical to those of nNOS isolated from human kidney 293 cells. The methods disclosed are contemplated to be useful in expressing large amounts of other nitric oxide synthases, as well as other proteins that are difficult to produce correctly folded in prokaryotes.
