Microglia activation in retinal degeneration [PDF]

Journal of Leukocyte Biology, 2007
AbstractMicroglia cells are phagocytic sentinels in the CNS and in the retina required for neuronal homeostasis and innate immune defense. Accumulating experimental evidence suggests that chronic microglia activation is associated with various neurodegenerative diseases including retinal dystrophies. Endogenous triggers alert microglia cells rapidly in

Presbycusis: Pathology, Signal Pathways, and Therapeutic Strategy

Advanced Science, EarlyView.
In ARHL, the stria vascularis, acting as a cochlear battery, gradually loses its ability to maintain the endocochlear potential, leading to impaired hair cell function and progressive hearing loss. Single‐cell sequencing reveals age‐related cellular changes in the cochlea, providing insights into the underlying mechanisms of aging and potential ...

HO-1-mediated ferroptosis as a target for protection against retinal pigment epithelium degeneration

Redox Biology, 2021
Oxidative stress-mediated retinal pigment epithelium (RPE) degeneration plays a vital role in retinal degeneration with irreversible visual impairment, most notably in age-related macular degeneration (AMD), but a key pathogenic factor and the targeted ...

Retinal Macrophages Synthesize C3 and Activate Complement in AMD and in Models of Focal Retinal Degeneration.

Investigative Ophthalmology and Visual Science, 2017
Purpose Complement system dysregulation is strongly linked to the progression of age-related macular degeneration (AMD). Deposition of complement including C3 within the lesions in atrophic AMD is thought to contribute to lesion growth, although the ...

Genetics‐Based Targeting Strategies for Precise Neuromodulation

Advanced Science, EarlyView.
In this Review, the fundamental principles and implementation protocols of genetics‐based precision neuromodulation are first introduced. Then, wireless and low‐invasive strategies based on nano‐transducing materials are highlighted, along with a dissection and analysis of the strengths and weaknesses of representative studies.

TREM2-dependent activation of microglial cell protects photoreceptor cell during retinal degeneration via PPARγ and CD36

Cell Death and Disease
Retinal degeneration is a collection of devastating conditions with progressive loss of vision which often lead to blindness. Research on retinal microglial cells offers great therapeutic potential in deterring the progression of degeneration. This study

Iron overload and iron chelating agent exposure in anemia-associated outer retinal degeneration: a case report and review of the literature

BMC Ophthalmology, 2021
Background Deferoxamine retinopathy is the informally designated term used to describe a characteristic pattern of outer retinal degeneration in iron-overloaded chronic anemia patients who are treated with deferoxamine. We hypothesize that insufficiently

Eosinophils‐Induced Lumican Secretion by Synovial Fibroblasts Alleviates Cartilage Degradation via the TGF‐β Pathway Mediated by Anxa1 Binding

Advanced Science, EarlyView.
Eosinophils play a crucial role in the progression of temporomandibular joint osteoarthritis (TMJOA). This study demonstrates that eosinophils, induced by OVA/IL‐5, promote Lumican secretion in the synovium, which binds to Annexin A1 in chondrocytes, inhibiting transforming growth factor β2 and Smad2/3 phosphorylation.

Deferiprone protects against photoreceptor degeneration by inhibiting parthanatos

Cell Death and Disease
Photoreceptor degeneration is the hallmark of retinitis pigmentosa. Identifying general mechanisms underlying photoreceptor cell death is key to developing effective, mutation-independent treatments to prevent vision loss.
