Metabolite channeling by a dynamic metabolon

Enzymes that synthesize a specialized metabolite congregate and disperse on an as-needed basis in the lipid membrane.

Tau phosphorylation—Not all bad

Phosphorylation of tau at a specific site mitigates, rather than enhances, symptoms in a mouse model of Alzheimer’s disease.

A. Ittner, S. W. Chua, J. Bertz, A. Volkerling, J. van der Hoven, A. Gladbach, M. Przybyla, M. Bi, A. van Hummel, C. H. Stevens, S. Ippati, L. S. Suh, A. Macmillan, G. Sutherland, J. J. Kril, A. P.

Sacral neurons reassigned

Contrary to a century-old dogma, the pelvic nerves and ganglia do not belong to the parasympathetic nervous system but to the sympathetic one.

I. Espinosa-Medina, O. Saha, F. Boismoreau, Z. Chettouh, F. Rossi, W. D. Richardson, J.-F. Brunet, The sacral autonomic outflow is sympathetic. Science 354, 893–897 (2016).[Abstract]
