Overexpressing neurogenic differentiation factor 1 in Müller cells improves retinal function after optic nerve crush injury in adult mice.

Optic nerve injury leads to axonal degeneration and the death of retinal ganglion cells, which ultimately causes vision loss. Notably, current treatments are limited. In the present study, we explored whether neurogenic differentiation factor 1 (NeuroD1 or ND1) overexpression in retinal Müller cells may repair the retina after optic nerve crush in mice.

Abnormal outer and inner retina in a mouse model of Huntington's disease with age.

Huntington's disease (HD) is a progressive neurodegenerative disorder characterized by motor dysfunction and cognitive decline. While retinal abnormalities have been documented in some HD patients and animal models, the nature of these abnormalities-specifically whether they originate in the inner or outer retina-remains unclear, particularly regarding their progression with age. This study investigates the retinal structure and function in HD transgenic mice (R6/1) compared to C57BL/6 J control mice at 2, 4, and 6 months of age, encompassing both pre-symptomatic and symptomatic stages of HD.
