Abstract

GPR56, one of the adhesion G‐protein–coupled receptors (GPCRs), plays an important role in the development of the cerebral cortex. Mutations in GPR56 cause a severe human cortical malformation called bilateral frontoparietal polymicrogyria (BFPP), characterized by a global malformation of the cerebral cortex that most severely affects the frontal and parietal regions. To characterize the expression pattern of GPR56 in the developing cerebral cortex, we developed a mouse monoclonal antibody against mouse GPR56. We revealed that GPR56 is expressed in multiple cell types in the preplate, marginal zone, subventricular zone (SVZ), and ventricular zone (VZ). Most interestingly, the expression of GPR56 in preplate neurons showed an anterior‐to‐posterior gradient at embryonic day (E) 10.5–11.5. In contrast, the expression pattern of the GPR56 ligand, collagen III, revealed no visible gradient pattern. With the widespread expression of GPR56 in the developing cortex, it is difficult to draw a specific conclusion as to which of the GPR56‐expressing cells are critical for human brain development. However, the correlation between GPR56 expression in neurons at E10.5–E11.5 and the anatomic distribution of the cortical malformation in both humans and mice suggests that its function in preplate neurons is indispensible.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
