Competing Interests

Marius C. Hoener and Lothar Lindemann are employees of F. Hoffmann-La Roche Ltd. Tomi Rantamäki, Hanna Antila and Eero Castrén have developed an analytical method that can be used to detect the levels or modifications (e.g. phosphorylation) of cellular proteins (FIN/US Provisional patent pending). This method can be used to screen for regulators of TrkB receptor signaling. This method has not been used in the current study. All other authors declare that they do not have any potential conflicts of interest related to this study.
