About this deal

The increased number of basally located progenitors in the neocortex of Robo1/Robo2-deficient mice is largely consistent with another report using distinct Robo1/Robo2 mutant mice ( Yeh et al., 2014). However, Yeh et al. reported that the number of aRGCs is increased in Robo1/Robo2 mutant mice ( Yeh et al., 2014). This discrepancy between the two studies may be due to the different mutant mouse lines used. The former used a hypomorphic Robo1 mutant, in which Ig-domain 1 and half of Ig-domain 2, which are the domains responsible for Slit binding, are still expressed ( Long et al., 2004; López-Bendito et al., 2007), whereas the latter study used a null mutant mouse line ( Lu et al., 2007; Andrews et al., 2008). Interestingly, treatment of cortical progenitor cells with the extracellular domain of Robo1 resulted in a reduction in the number of progenitor cells expressing the aRGC marker Pax6 ( Yeh et al., 2014). Thus, the remaining Ig domains in the hypomorphic Robo1 mutant mice may affect the number of aRGCs. Swanson, J. A. Shaping cups into phagosomes and macropinosomes. Nat. Rev. Mol.

It is defined as the ratio of the surface area of a sphere with the same volume as the given object (in this case, a cell) to the surface area of the object. The shape factor is 1 for a perfect sphere; becoming smaller for more irregular shapes. RhoA activation, total RhoA, and Rac1/2/3 activation G-LISA assays Jurney, W. M. et al.

Serotonin reuptake by serotonin transporters is crucial for maintaining normal levels of serotonin in the neocortex. Dysfunctions of serotonin transporters and resultant high serotonin levels are observed in ASD patients ( Schain and Freedman, 1961; Muller et al., 2016). As Robo has been shown to promote serotonin transporter expression in Drosophila ( Couch et al., 2004), and the expression of ROBO1, ROBO2, ROBO3, and ROBO4 was reduced in patients diagnosed as having ASD ( Anitha et al., 2008), decreased ROBO expression might increase serotonin level, which is associated with ASD. As excess serotonin in the developing mouse neocortex is known to affect the migration of both pyramidal neurons and interneurons ( Riccio et al., 2009, 2011), decreased ROBO expression might impair neuronal migration in a non-cell autonomous manner in addition to the cell-autonomous manner (see section “Slit-Robo Signaling in Neuronal Migration”).

Guan, C. B. et al. Long-range Ca2+ signaling from growth cone to soma mediates reversal of neuronal migration induced by Slit-2. Cell 129, 385–395 (2007). Borrell’s group reported that Slit-Robo signaling is involved in the proliferation-differentiation balance of neural progenitor cells ( Borrell et al., 2012, Figure 1). Robo1/ Robo2 expression is detected in the VZ. Loss of Robo1/2 signaling leads to a decrease in the number of aRGCs and a concomitant increase in the number of basally located cells expressing the bIP marker Tbr2. However, these Tbr2-expressing cells retain apical processes and are integrated into the ventricular (apical) surface, suggesting that Robo signaling regulates two events, i.e., the production of intermediate progenitors (IPs) from aRGCs and their delamination from the apical junction belt.

Conflict of interest

SLIT2/ROBO1 signaling has been reported to activate RhoA in other cell types by either inactivation of Fyn kinase 56, or activation of TRIO 55. SLIT2 can mediate RhoA inhibition via calcium signaling in neurons 77. Following a brief exposure to NSlit2, we observed a significant increase in RhoA activity (Fig. 2b), and yet the same treatment failed to inactivate Fyn (Supplementary Fig. 3b). Our results are in keeping with the previous study which observed Fyn inactivation only after prolonged exposure to SLIT2 56. In line with another study 78, we detected Trio mRNA in transformed RAW264.7 cells but not in primary BMDM (Supplementary Fig. 3a). This suggests that SLIT2-induced stimulation of TRIO might contribute to RhoA activation in RAW264.7 cells but cannot explain the phenotype we observed in primary macrophages. Prasad, A. et al.
