Three Strategies to Induce Neurotrophic Keratitis and Nerve Regeneration in Murine Cornea.

The cornea is a transparent tissue that covers the eye and is crucial for clear vision. It is the most innervated tissue in the body. This innervation provides sensation and trophic function to the eye and contributes to preserving corneal integrity.

TBC1D32 variants disrupt retinal ciliogenesis and cause retinitis pigmentosa.

Retinitis pigmentosa (RP) is the most common inherited retinal disease (IRD) and is characterized by photoreceptor degeneration and progressive vision loss. We report 4 patients presenting with RP from 3 unrelated families with variants in TBC1D32, which to date has never been associated with an IRD. To validate TBC1D32 as a putative RP causative gene, we combined Xenopus in vivo approaches and human induced pluripotent stem cell-derived (iPSC-derived) retinal models.

CSF1R inhibition at chronic stage after spinal cord injury modulates microglia proliferation.

Traumatic spinal cord injury (SCI) induces irreversible autonomic and sensory-motor impairments. A large number of patients exhibit chronic SCI and no curative treatment is currently available. Microglia are predominant immune players after SCI, they undergo highly dynamic processes, including proliferation and morphological modification.

Retinoic acid delays initial photoreceptor differentiation and results in a highly structured mature retinal organoid.

Background: Human-induced pluripotent stem cell-derived retinal organoids are a valuable tool for disease modelling and therapeutic development. Many efforts have been made over the last decade to optimise protocols for the generation of organoids that correctly mimic the human retina. Most protocols use common media supplements; however, protocol-dependent variability impacts data interpretation.
