Comment réaliser une résection du tissu cérébral avec GLOW400 AR

L'IRM peropératoire est une forme de visualisation peropératoire en temps réel, mais si une visualisation plus approfondie pour identifier une tumeur pendant la chirurgie est souhaitée, il est…
Automated Laser Microdissection for Proteome Analysis

Deep Visual Proteomics Provides Precise Spatial Proteomic Information

Despite the availability of imaging methods and mass spectroscopy for spatial proteomics, a key challenge that remains is correlating images with single-cell resolution to protein-abundance…
Multiplexed Cell DIVE imaging of Adult Human Alzheimer’s brain tissue section demonstrating expression of markers specific to astrocytes (GFAP, S100B), microglia (TMEM119, IBA1), AD-associated markers (p-Tau217, β-amyloid) and immune cells such as CD11b+, CD163+, CD4+, and HLA-DRA+, clustered around the β-amyloid plaques.

Spatial Analysis of Neuroimmune Interactions in Alzheimer’s Disease

Alzheimer’s disease (AD) is a complex neurodegenerative disorder characterized by neurofibrillary tangles, β-amyloid plaques, and neuroinflammation. These dysfunctions trigger or are exacerbated by…
