Beta-Amyloid (1-40) (Aβ40) is an aggregation prone protein, which undergoes a nucleation-dependent aggregation process causing the pathological neurodegeneration by amyloid plaque formation implicated in Alzheimer’s disease. In this thesis, we investigated the effects of small molecule modulators extracted from the marine invertebrate Pseudopterogorgia elisabethae on the Aβ40 amyloidogenic process using in- vitro ThT fluorescence assay and atomic force microscopy. We also investigated the effects of neutral and anionic phospholipid liposomes on Aβ40 aggregation. Our results show that a marine natural product Pseudopterosin-A and its derivatives can suppress and modulate the Aβ40 aggregation process. Furthermore, our results demonstrate that a neutral phospholipid liposome inhibits Aβ40 fibril formation, whereas the anionic liposomes promote it. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2015 / FAU Electronic Theses and Dissertations Collection
