An Observation Of Immunological Effect, A Diet Enhanced With Spirulina And Treatment With Fractalkine In Models Of Parkinson's Disease, Mibel M. Pabón

USF Tampa Graduate Theses and Dissertations

In my dissertation research we used use human wild type α-synuclein gene expression using an adeno-associated viral vector (AAV9) that induced a slowly progressive loss of dopamine (DA) neurons in the Substantia nigra (SN) as one of our animal model of Parkinson’s disease (PD). It is our hypothesis that neuroinflammation predisposes the brain to susceptibility to neurodegenerative diseases. Thus we examined the progression of a PD lesion and examined the manipulations of the immune system to understand further the inflammatory role when we administered exogenous soluble fractalkine.

The specific etiology of neurodegeneration in PD is unknown, but the inflammatory mechanisms …

Characterization Of The Role Of Nicotine And Delta 9-Thc In Modulation Of Neuroinflammation, Jared C. Ehrhart

USF Tampa Graduate Theses and Dissertations

Neuroinflammation is a major driving force in the progression of neurodegenerative disorders. Nicotinic acetylcholine receptors, as well as cannabinoid CB2 receptors, have been shown to have strong anti-inflammatory properties when activated. These effects are shown, in vivo, to be a result of stimulation of α7 nAChRs and CB2 cannabinoid receptors. Microglia cells, an immune cell in the brain, are shown to express both of these receptor subtypes. The studies detailed herein, investigated the ability of two compounds, nicotine and Δ9-THC, in modulation of inflammatory processes. Stimulation of these receptors on microglia using nicotine and Δ9-THC blocked the activation of these …
