\u201cThis led us to the following idea: what if instead of preventing the formation of droplets, we created conditions that would drive Tau and alpha synuclein inside the droplets toward their healthy path, discouraging them from taking the disease path?\u201d said a co-corresponding author of the work.<\/p>\n

The team worked with biochemical and biophysical techniques, high-resolution microscopy and neuronal-based assays to investigate tubulin\u2019s role in modulating and preventing the formation of toxic aggregates in droplets.<\/p>\n

The researchers show that Tubulin modulates Tau:\u03b1Syn condensates by promoting microtubule interactions and inhibiting homotypic and heterotypic pathological oligomers. Tubulin partitioning into condensates promotes microtubule polymerization and prevents Tau and \u03b1Syn oligomerization.<\/p>\n

In the absence of Tubulin, Tau-driven condensation accelerates formation of pathogenic Tau:\u03b1Syn heterodimers and amyloid fibrils. The authors also identify distinct Tau and \u03b1Syn structural states in pathological Tubulin-absent versus physiological Tubulin-rich condensates.<\/p>\n

\u201cWhen tubulin levels are low, as it has been found in Alzheimer\u2019s disease, microtubules are less abundant and Tau and alpha synuclein can form toxic aggregates,\u201d the author said. \u201cBut when tubulin is present, Tau and alpha\u2011synuclein shift away from harmful aggregates and instead promote the assembly of healthy microtubules,\u201d the author said. \u201cTubulin redirects the activity of these proteins by giving them something productive to do.\u201d ScienceMission sciencenewshighlights.<\/p>\n

Researchers <\/b>have discovered a potential new strategy to fight back against Alzheimer\u2019s and Parkinson\u2019s diseases, conditions that are linked to the toxic accumulation of Tau and alpha synuclein protein clumps in the brain. The team reports in Nature Communications<\/a> that tubulin, the building block of microtubules, the cell\u2019s internal \u2018railway tracks,\u2019 can stop Tau and alpha synuclein from forming toxic clumps and instead steer them into their normal, healthy roles.<\/p>\n
