Investigating The Role Of Endothelin-1 In Reactive Astrocytosis, Candace Betancourt-Szymanowska

Master's Theses

Glaucoma is a progressive optic neuropathy which results in blindness for many patients, even with treatment. Endothelin-1 (ET-1) is a vasoactive peptide known to be aberrantly upregulated in the eyes of individuals with glaucoma. Optic nerve head astrocytes (ONHA) are the resident glial cell of the optic nerve head and are among the first cell types to undergo changes to a reactive phenotype. In this thesis, we investigated the role of ET-1 overexpression and its putative role in eliciting a reactive phenotype in ONHA by inducing lentiviral-mediated over-expression of EDN1. ONHA transduced with EDN1 (ONHA ET-1) were verified to be …

Transcleral Chemotherapeutic Delivery By Fibrin Sealant In The Treatment Of Retinoblastoma, Christopher Himes
