Inflammation and Occlusive Retinal Vasculitis Post Faricimab.
JAMA Ophthalmol
January 2025
Truhlsen Eye Center, Department of Ophthalmology and Visual Sciences, University of Nebraska Medical Center, Omaha.
Importance: Randomized clinical trials have shown the safety and efficacy of faricimab as a novel vascular endothelial growth factor and angiopoietin-2 inhibitor in the treatment of neovascular age-related macular degeneration (nAMD) and macular edema of various etiologies. However, more rare adverse events may not be considered in clinical trials.
Objective: To describe 3 eyes that developed irreversible vision loss following initial mild intraocular inflammation (IOI) to faricimab.
Manganese exposure induces parkinsonism-like symptoms by Serpina3n-TFEB-v/p-ATPase signaling mediated lysosomal dysfunction.

Manganese (Mn) is a neurotoxin that has been etiologically linked to the development of neurodegenerative diseases in the case of overexposure. It is widely accepted that overexposure to Mn leads to manganism, which has clinical symptoms similar to Parkinson's disease (PD), and is referred to as parkinsonism. Astrocytes have been reported to scavenge and degrade extracellular α-synuclein (α-Syn) in the brain.

Substantial evidence points to the early onset of peripheral inflammation in the development of Parkinson's disease (PD), supporting the "body-first" hypothesis. However, there remains a notable absence of PD-specific animal models induced by inflammatory cytokines. This study introduces a novel mouse model of PD driven by the proinflammatory cytokine CXCL1, identified in our previous research.

Particle size and surface properties are crucial for lymphatic drainage (LN), dendritic cell (DC) uptake, DC maturation, and antigen cross-presentation induced by nanovaccine injection, which lead to an effective cell-mediated immune response. However, the manner in which the particle size and surface properties of vaccine carriers such as mesoporous silica nanoparticles (MSNs) affect this immune response is unknown. We prepared 50, 100, and 200 nm of MSNs that adsorbed ovalbumin antigen (OVA) while modifying -glucan to enhance immunogenicity.

Osteoarthritis (OA) is a frequent chronic illness in orthopedics that poses a major hazard to patient health. cell therapy is emerging as a therapeutic option, but its efficacy is influenced by both the inflammatory milieu and the amount of stem cells, limiting its use. In this study, we designed a novel injectable porous microsphere (PM) based on microfluidic technology that can support mesenchymal stem cells (MSCs) therapy by combining polylactic-glycolic acid copolymer, kartogenin, polydopamine, stromal cell-derived factor-1, and copper-doped bioactive glass (CuBG).
