Human immunoglobulins and Fc fragments promote microtubule assembly via tau proteins and induce conformational changes of neuronal microtubules in vitro.

The influence of human immunoglobulins (Ig) in neuronal cytoskeleton stability was studied in vitro. Here we show that human Ig and Fc fragments stimulate animal and human microtubule assembly by binding to microtubules via tau isoforms. In presence of Ig, microtubules show increased aggregation, twisting and rigidity. Non-immune Ig and Fc fragments promote microtubule assembly in temperature-dependent manner and stabilize microtubules at a molecular ratio of 1 Ig per 4 tubulin dimers. These in vitro data provide an experimental support for an immuno-mediated modulation of the cytoskeleton. In conjunction with previous neuropathological data, they suggest that Ig could participate in early stages of neurodegeneration by affecting the microtubule stability in vivo.
