Antibody helps detect protein implicated in Alzheimer’s, other diseases
Summary: The article discusses research looking to find less invasive ways to identify and then track the progress of neurodegenerative diseases like Alzheimer’s. They have accomplished the first step by crafting an antibody which binds to the protein tau, which is present in tangles when damage to the brain is occurring. The antibody allows tau to stay present in the blood and accumulate long enough to be observable via blood tests.
Connection: The article discusses the use of an human antibody, but in a way we didn’t really cover in class. The antibody is not used as a flag for the destruction of a microbe or “not-self” entity in the body, but rather keep an entity around long enough to track its concentrations.
Critical Analysis: This article does an excellent job of explaining the issues related to diagnosing neurodegenerative diseases, as well as the way in which the protein tau is associated and was identified as a potential measurable product for blood tests. Though the study has only done limited preliminary human trials, they were able to magnify the presence of tau in the blood of individuals with known neurodegenerative diseases. I believe the article did a great job of translating the innovative way in which scientists approach problems like that of diagnostics, and the interdisciplinary cooperation and literacy that is at the command of these researchers to accomplish what was discussed.
Question: Would this antibody have the ability to track damage as it accumulates in individuals like football players, perhaps as a longitudinal study to gain more data and a predictive model for brain damage?
