Resident Immune Cells Of The Avascular Lens: Mediators Of The Injury And Fibrotic Response Of The Lens., A. Menko, Jodirae Dedreu, Caitlin M. Logan, Heather Paulson, Alex V Levin, Janice L Walker
Department of Pathology, Anatomy, and Cell Biology Faculty Papers
Tissues typically harbor subpopulations of resident immune cells that function as rapid responders to injury and whose activation leads to induction of an adaptive immune response, playing important roles in repair and protection. Since the lens is an avascular tissue, it was presumed that it was absent of resident immune cells. Our studies now show that resident immune cells are a shared feature of the human, mouse, and chicken lens epithelium. These resident immune cells function as immediate responders to injury and rapidly populate the wound edge following mock cataract surgery to function as leader cells. Many of these resident …
Properties Of Multivesicular Release From Mouse Rod Photoreceptors Support Transmission Of Single-Photon Responses, Cassandra L. Hays, Asia L. Sladek, Greg D. Field, Wallace B. Thoreson
Properties Of Multivesicular Release From Mouse Rod Photoreceptors Support Transmission Of Single-Photon Responses, Cassandra L. Hays, Asia L. Sladek, Greg D. Field, Wallace B. Thoreson
Journal Articles: Ophthalmology
Vision under starlight requires rod photoreceptors to transduce and transmit single-photon responses to the visual system. Small single-photon voltage changes must therefore cause detectable reductions in glutamate release. We found that rods achieve this by employing mechanisms that enhance release regularity and its sensitivity to small voltage changes. At the resting membrane potential in darkness, mouse rods exhibit coordinated and regularly timed multivesicular release events, each consisting of ~17 vesicles and occurring two to three times more regularly than predicted by Poisson statistics. Hyperpolarizing rods to mimic the voltage change produced by a single photon abruptly reduced the probability of …

Traumatic brain injury (TBI) affects over 3 million individuals every year in the U.S. There is growing appreciation that TBI can produce systemic modifications, which are in part propagated through blood–brain barrier (BBB) dysfunction and blood–brain cell interactions. As such, platelets and leukocytes contribute to mechanisms of thromboinflammation after TBI. While these mechanisms have been investigated in experimental models of contusion brain injury, less is known regarding acute alterations following mild closed head injury. To investigate the role of platelet dynamics and bioenergetics after TBI, we employed two distinct, well-established models of TBI in mice: the controlled cortical impact (CCI) …

Phase 1
Introduction: Retinoblastoma due to germline mutation has a greater risk of bilateral presentation, and multifocal or extraocular involvement. In solitary unilateral retinoblastoma, the inheritance pattern is less understood and assumed to be somatic. We assessed the likelihood of germline inheritance in children with unilateral retinoblastoma and whether it varies based on age at presentation.
Methods: This was a retrospective case study assessing 482 consecutive patients with solitary unilateral retinoblastoma at Wills Eye Hospital between 1972 and 2020 for the likelihood of germline inheritance based on age at presentation (≤1 year vs. >1 year). Germline inheritance was deemed likely if …

Student Papers, Posters & Projects
Purpose: Traumatic optic neuropathy (TON) is often caused by blunt head trauma and has no currently effective treatment. Common animal models of TON induced by surgical crush injury are plagued by variability and do not mimic typical mechanisms of TON injury. Traumatic head impact models have recently shown evidence of TON, but the degree of head impact necessary to consistently induce TON is not well characterized, and it is examined here.
Methods: Traumatic skull impacts to C57BL/6J mice were induced using an electromagnetic controlled impact device. One impact performed at two depths (mild and severe), as well as three and …

Direct Multiplexing Of Low Order Aberration Modes In A Photopolymerbased Holographic Element For Analog Holographic Wavefront Sensing, Emma Branigan, Suzanne Martin, Matthew Sheehan, Kevin Murphy
Conference Papers
The fabrication of an analog holographic wavefront sensor, capable of detecting the low order defocus aberration, was achieved in an acrylamide-based photopolymer. While other implementations of holographic wavefront sensors have been carried out digitally, this process utilises a recording setup consisting only of conventional refractive elements so the cost and complexity of holographic optical element (HOE) production could be much reduced. A pair of diffraction spots, corresponding to a maximum and minimum amount of defocus, were spatially separated in the detector plane by multiplexing two HOEs with different carrier spatial frequencies. For each wavefront with a known aberration that was …
