ARVO 2025 presentation: Combined administration of BDNF and CNTF provides superior neuroprotection as compared to BDNF alone in a mouse optic nerve crush model

ARVO 2025 presentation: Combined administration of BDNF and CNTF provides superior neuroprotection as compared to BDNF alone in a mouse optic nerve crush model

Glaucoma, a leading cause of blindness and visual impairment worldwide, is characterized by progressive loss of retinal ganglion cells (RGCs) and damage to the optic nerve. Neurotrophic factors, including brain-derived neurotrophic factor (BDNF) and ciliary neurotrophic factor (CNTF), have been extensively studied for their potential to promote RGC survival and axonal regeneration. However, BDNF's efficacy is restricted by receptor desensitization, while CNTF alone often induces inflammation and gliosis, limiting its therapeutic potential. This study was aimed at evaluating if a combination of BDNF and CNTF offers synergistic effects, providing superior neuroprotection as compared to either factor alone.

ARVO 2025 presentation: Phosphate-buffered saline administered intravitreally at P12 blocks neovascularization in the mouse oxygen-induced retinopathy model

ARVO 2025 presentation: Phosphate-buffered saline administered intravitreally at P12 blocks neovascularization in the mouse oxygen-induced retinopathy model

Intravitreally injected phosphate-buffered saline (PBS) is known to decrease neovascularization in the mouse oxygen-induced retinopathy (OIR) model, and it is commonly used as a vehicle control in preclinical studies evaluating therapeutic efficacy. This study aimed at evaluating the impact of intravitreally (IVT) administered PBS on neovascularization and revascularization at various timepoints after OIR induction. Aflibercept (Eylea®) was used as a reference control.
