Self‐Sealing Microneedles Improve Precision and Reduce Reflux in Subretinal Cell Transplantation

Advanced Materials Technologies, EarlyView.
Ultrafine 49G microneedles enable subretinal delivery of induced pluripotent stem cell‐derived retinal pigment epithelial cells through a 50 µm outer diameter tip. Compared with conventional 38G microcannulas, these microneedles reduce cell suspension reflux in a rabbit model, highlighting the potential of microinvasive delivery instruments to improve ...

Lrit1, a Retinal Transmembrane Protein, Regulates Selective Synapse Formation in Cone Photoreceptor Cells and Visual Acuity

Cell Reports, 2018
Summary: In the vertebrate retina, cone photoreceptors play crucial roles in photopic vision by transmitting light-evoked signals to ON- and/or OFF-bipolar cells.

Arrestins expressed in killifish photoreceptor cells [PDF]

FEBS Letters, 1997
Two kinds of cDNA fragments (KfhArr‐R and KfhArr‐C) encoding the putative arrestins of killifish,Oryzias latipes, were isolated. The distributions of these transcripts were investigated by in situ hybridization, and it was demonstrated that KfhArr‐R and KfhArr‐C are expressed in, respectively, rod and all four types of cone cells.

Organoids as Building Blocks for Adaptive and Resilient Biohybrid Robots

Advanced Materials Technologies, EarlyView.
ABSTRACT Biohybrid robots combine engineered living tissues with synthetic materials and have emerged as a promising class of soft robotic systems capable of mimicking biological functions such as biodegradability, energy efficiency and flexible motions. By integrating biological and synthetic components, these systems leverage complementary properties

Characterization and Transplantation of CD73-Positive Photoreceptors Isolated from Human iPSC-Derived Retinal Organoids

Stem Cell Reports, 2018
Summary: Photoreceptor degenerative diseases are a major cause of blindness for which cell replacement is one of the most encouraging strategies. For stem cell-based therapy using human induced pluripotent stem cells (hiPSCs), it is crucial to obtain a ...

Minocycline decreases CCR2-positive monocytes in the retina and ameliorates photoreceptor degeneration in a mouse model of retinitis pigmentosa.

PLoS ONE, 2021
Retinal inflammation accelerates photoreceptor cell death caused by retinal degeneration. Minocycline, a semisynthetic broad-spectrum tetracycline antibiotic, has been previously reported to rescue photoreceptor cell death in retinal degeneration.

P2X7 Receptor Modulation of Visual Responses in the Retina [PDF]

, 2015
Adenosine 5’ triphosphate (ATP)-gated P2X7 receptors (P2X7Rs) are known to act as conduits for photoreceptor and retinal ganglion cell (RGC) damage, consequences of various neurodegenerative conditions within the visual pathway. Growing evidence supports

Bio‐Inspired Object Retrieval via Proximity‐Guided Adaptive Thigmotactic Exploration and Neuromorphic Recognition

Advanced Robotics Research, EarlyView.
Sparse active‐infrared proximity sensing is coupled to an adaptive thigmotactic controller for camera‐inaccessible object retrieval. After grasping, receptor‐informed encoding transforms force, temperature, and wrist force–torque signals into spike trains for spiking neural network recognition.

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

Advanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.
