(H) Primary hippocampal neurons co-transfected with ClC-3 and synaptobrevin (syb2), both luminally tagged with pHluorin or the pH-sensitive mOrange Ramirez et al, 2012(), respectively, were stimulated by 200 action potentials (APs) at 20 Hz (indicated by bar). Vesicle exocytosis was monitored by fluorescence increase upon exposure to extracellular neutral pH. Note that only Syb2 and not ClC-3 shows signs of exocytosis. Traces were corrected for photobleaching. The initial decay of the pHluorin signal is probably due to the high light exposure, which forces the fluorophores into a transient dark-state Dean et al, 2011(). Averaged fluorescence traces (n=10), error bars, s.e.m.

(J) Model for two TP53-dependent pathways underlying primary microcephaly. In the first model, NPCs with mutations in centrosome genes take longer to assemble their spindle in mitosis. This delay triggers the activation of the mitotic surveillance pathway, which activates TP53 through 53BP1 and USP28. By contrast, in microcephaly caused by mutations in genes required for DNA repair or genome stability, centrosome function and mitotic duration are unaffected. Instead, accumulated DNA lesions trigger DNA damage signaling in NPCs to activate TP53. In both models, increased TP53 activity leads to apoptosis, thus depleting the NPC pool and decreasing the final number of neurons.
