Erratum

Following the publication of our article [1] we noticed that the western blot in Fig. 3c (Fig. 1c here) was incorrectly labelled. The S307-AKT band should instead be labelled T308-AKT. We have provided the correct figure here.

Western blot analyses. The infusion of LPS into the fourth ventricle increased the protein level (a, b) of PKCζ, black square, P < 0.05 versus aCSF. Insulin treatment reduced, black diamond, P < 0.001, PKCζ levels as compared to LPS. (c, d) No significant changes were observed for p-AKT Threonine 308 or Serine 473
