Traumatic stress often causes long-term pathological changes. To elucidate the molecular basis of these stress-induced changes, Meshorer et al. analyzed the regulation of expression of acetylcholinesterase (AChE) splice variants at cholinergic synapses in the central nervous system. They saw a change from the dominant membrane-bound AChE-S form to the rare soluble AChE-R form. This switch could be triggered by various stresses, occurred very rapidly, and could last for many weeks.
