Frontiers in molecular neuroscience

Dhingra A, Tummala SR, Lyubarsky A, Vardi N.
PMID: 25018695
Front Mol Neurosci. 2014 Jun 27;7:60. doi: 10.3389/fnmol.2014.00060. eCollection 2014.

The ubiquitous second messenger cGMP is synthesized by guanylyl cyclase and hydrolyzed by phosphodiesterase (PDE). cGMP mediates numerous signaling pathways in multiple tissues. In the retina, cGMP regulates signaling in nearly every cell class including photoreceptors, bipolar cells, amacrine...

The P2X7 Receptor Primes IL-1β and the NLRP3 Inflammasome in Astrocytes Exposed to Mechanical Strain.

Frontiers in cellular neuroscience

Albalawi F, Lu W, Beckel JM, Lim JC, McCaughey SA, Mitchell CH.
PMID: 28848393
Front Cell Neurosci. 2017 Aug 08;11:227. doi: 10.3389/fncel.2017.00227. eCollection 2017.

Inflammatory responses play a key role in many neural pathologies, with localized signaling from the non-immune cells making critical contributions. The NLRP3 inflammasome is an important component of innate immune signaling and can link neural insult to chronic inflammation....

The P2X(7) receptor in retinal ganglion cells: A neuronal model of pressure-induced damage and protection by a shifting purinergic balance.

Purinergic signalling

Mitchell CH, Lu W, Hu H, Zhang X, Reigada D, Zhang M.
PMID: 19241145
Purinergic Signal. 2009 Jun;5(2):241-9. doi: 10.1007/s11302-009-9142-6. Epub 2009 Feb 25.

Retinal ganglion cells process the visual signal and transmit it along their axons in the optic nerve to the brain. Molecular, immunohistochemical, and functional analyses indicate that the majority of retinal ganglion cells express the ionotropic P2X(7) receptor. Stimulation...

Joint effects of illumination geometry and object shape in the perception of surface reflectance.

i-Perception

Olkkonen M, Brainard DH.
PMID: 23145259
Iperception. 2011;2(9):1014-34. doi: 10.1068/i0480. Epub 2011 Dec 14.

Surface properties provide useful information for identifying objects and interacting with them. Effective utilization of this information, however, requires that the perception of object surface properties be relatively constant across changes in illumination and changes in object shape. Such...

Erratum: Non-invasive assessment of human cone photoreceptor function: erratum.

Biomedical optics express

Complexity of the Class B Phenotype in Autosomal Dominant Retinitis Pigmentosa Due to Rhodopsin Mutations.

Investigative ophthalmology & visual science

Jacobson SG, McGuigan DB, Sumaroka A, Roman AJ, Gruzensky ML, Sheplock R, Palma J, Schwartz SB, Aleman TS, Cideciyan AV.
PMID: 27654411
Invest Ophthalmol Vis Sci. 2016 Sep 01;57(11):4847-4858. doi: 10.1167/iovs.16-19890.

PURPOSE: Previously, patients with RHO mutations and a class A phenotype were found to have severe early-onset loss of rod function, whereas patients with a class B phenotype retained rod function at least in certain retinal regions. Here class...

(1) Background: Vertical cup-to-disc ratio (CDR) is an important measure for evaluating damage to the optic nerve head (ONH) in glaucoma patients. However, this measure often does not fully capture the irregular cupping observed in glaucomatous nerves. We developed...
