Biography/CV

Aijaz Parray, an alumnus of the ENP graduate program, contributed to an important finding on the organization of the retina. He and his teammates used a mouse model to study stratification of the layers of the retina. They discovered that the transmembrane semaphorin Sema6A targets its receptor PlexA4 to control lamina-specific neuronal stratification. For more details, see the article:
