Acetylated tubulin is essential for touch sensation in mice

Kai Johnsson, Luc Reymond, Antonino Asaro

At its most fundamental level, touch sensation requires the translation of mechanical energy into mechanosensitive ion channel opening, thereby generating electro-chemical signals. Our understanding of this process, especially how the cytoskeleton influenc ...
