7 September 2023

In the pursuit of identifying the underlying pathways of ocular diseases, the use of cell lines such as (retinal ganglion cell-5) RGC-5 and 661W became a valuable tool, including pathologies like retinal degeneration and glaucoma. In 2001, the establ...

Retinal ganglion cell (RGC) death occurs in many eye diseases, such as glaucoma and traumatic optic neuropathy (TON). Increasing evidence suggests that the susceptibility of RGCs varies to different diseases in an RGC type-dependent manner. We previo...

(1) Background: Diabetic retinopathy (DR), caused by hypo- and hyperglycaemia, is the leading cause of blindness. Hypoglycemia induces endoplasmic reticulum stress and retinal cell death in mice, and low-glucose conditions induce macroautophagy/autop...

  • Manuel Guzmán-Navarro

Excitotoxicity has been linked to the pathogenesis of several serious degenerative ocular diseases. Long-term overactivation of the NMDA receptor by glutamate in retinal ganglion cells (RGCs) results in degeneration, apoptosis and loss of function le...
