Background on Tau Proteins
Tau proteins are microtubule-associated proteins that are essential for maintaining the stability of microtubules in neurons. In healthy cells, tau functions to promote microtubule assembly and stability, which are vital for intracellular transport and overall neuronal health. However, in tauopathies such as Alzheimer’s disease and frontotemporal dementia, tau proteins undergo hyperphosphorylation, leading to their aggregation into neurofibrillary tangles. This pathological transformation disrupts cellular function, resulting in neuronal death and cognitive decline. Understanding the behavior and alterations of tau proteins establishes a clear link to the necessity for targeted interventions, such as the use of tau antibodies like 12e8.
Development of the 12e8 Antibody
The development of the 12e8 antibody originated from a growing need for specific targets in tau pathology. Researchers aimed to create an antibody that could selectively bind to hyperphosphorylated tau without cross-reactivity to non-phosphorylated forms. The 12e8 antibody was developed through hybridoma technology, which allows the production of monoclonal antibodies with high specificity. This specificity is crucial for both diagnostic purposes and therapeutic applications.
