Wounding corneal epithelium establishes a laterally oriented, DC electric field (EF). Corneal epithelial cells (CECs) cultured in similar physiological EFs migrate cathodally, but this requires serum growth factors. Migration depends also on the substrate. On fibronectin (FN) or laminin (LAM) substrates in EF, cells migrated faster and more directly(More)
Signaling by members of the TGFbeta superfamily is thought to be transduced by Smad proteins. Here, we describe a zebrafish mutant in smad5, designated somitabun (sbn). The dominant maternal and zygotic effect of the sbntc24 mutation is caused by a change in a single amino acid in the L3 loop of Smad5 protein which transforms Smad5 into an antimorphic(More)
BACKGROUND Given the presence of neural progenitor cells (NPC) in the retina of other species capable of differentiating into multiple neural components, the authors report the presence of NPC in the adult human retina. A resident population of NPC suggests that the retina may constitutively replace neurons, photoreceptors, and glia. METHODS Adult human(More)
AIMS To establish current epidemiological data, risks, and interventional outcomes of newly diagnosed sympathetic ophthalmia (SO). METHODS Prospective surveillance took place of all permanently employed ophthalmologists in the UK and Republic of Ireland by a monthly reporting card through the British Ophthalmological Surveillance Unit. Case ascertainment(More)
A 62-year-old female patient presented to our clinic complaining of a 2 month history of shimmering photopsias and floaters. An ocular examination, fluorescein angiography, and electrophysiological testing were obtained that suggested either an inflammatory retinal vasculitis or a paraneoplastic syndrome. Melanoma-associated retinopathy was highly suspected(More)
The retina contains two distinct populations of monocyte-derived cells: perivascular cells (macrophages) and parenchymal cells (microglia), important in homeostasis, neuroinflammation, degeneration, and injury. The turnover of these cells in the retina and their repopulation in normal physiological conditions have not been clarified. Bone marrow (BM) cells(More)
Uveitis denotes inflammation of the uveal tract of the eye and is generally categorised as either anterior (involving the iris/ciliary body) or posterior (involving the choroid as well as adjacent structures including pigment epithelium and retina). Although uveitis is a known cause of blindness, until recently there were few data reflecting the prevalence(More)
BACKGROUND Non-infectious uveitis is a potentially sight-threatening ocular disorder caused by chronic inflammation and its complications. Therapeutic success is limited by systemic adverse effects associated with long-term corticosteroid and immunomodulator use if topical medication is not sufficient to control the inflammation. We aimed to assess the(More)
