Amyloid beta (Aβ) is considered a major component in the progression of degenerative disease like Alzheimer’s disease. In an attempt to cure Alzheimer’s before it has presented, this project proposes a study on the effects of protegrin-1 (PG-1) on the aggregation of Aβ. By cross-seeding to form a PG-1- Aβ heterocomplex, it is believed that aggregation of Aβ on the human brain can be inhibited, thus helping to stop the neurodegeneration caused by Alzheimer’s disease. To complete this project, an initial literature review of previous work done by the graduate student leading the project will be completed. After this, experiments will be conducted on PG-1-Aβ heterocomplexes. These experiments will include a variety of spectroscopy and microscopy, showing the extent of which they have cross-seeded. By performing these tests, it is possible to view the structure of the heterocomplex as well as if Aβ aggregation was inhibited as desired. The final step of the project will be testing on bacterial and cell assays. While lab experiments are useful, it is best to analyze how different structures perform in a biological environment. By using bacterial and cell assays, the effect of PG-1-Aβ heterocomplexes on the biological aggregation of Aβ can be analyzed.
