The role of TRPV4 channels in ocular function and pathologies.

Transient potential receptor vanilloid 4 (TRPV4) is an ion channel responsible for sensing osmotic and mechanical signals, which in turn regulates calcium signaling across cell membranes. TRPV4 is widely expressed throughout the body, and plays an…

Decreased Energy Capacity And Increased Autophagic Activity In Optic Nerve Axons With Defective Anterograde Transport

PURPOSE. Autophagy is a critical process, compromised in neurodegenerative disease, by which terminally differentiated cells like neurons manage cytoskeletal and organelle turnover. How autophagy relates to associated neurodegenerative pathologies…

Proximal inhibition of p38 MAPK stress signaling prevents distal axonopathy

The p38 mitogen-activated protein kinase (MAPK) isoforms are phosphorylated by a variety of stress stimuli in neurodegenerative disease and act as upstream activators of myriad pathogenic processes. Thus, p38 MAPK inhibitors are of growing interest…

Suppression of transforming growth factor-beta effects in rabbit subconjunctival fibroblasts by activin receptor-like kinase 5 inhibitor

Purpose: Transforming growth factor-beta (TGF-beta) activity has been implicated in subconjunctival scarring in eyes following glaucoma filtration surgery (GFS). The purpose of this study is to determine whether an inhibitor for activin receptor-like…

Early pro-inflammatory cytokine elevations in the DBA/2J mouse model of glaucoma

Background: Neuroinflammation-astrogliosis, microglial activation, and changes in cytokine signaling-is a prominent feature of neurodegenerative disorders. Glaucoma is a group of chronic neurodegenerative conditions that make up the leading cause of…
