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…

A Guide to Spatial Biology

What is spatial biology, and how can researchers leverage its tools to meet the growing demands of biological questions in the post-omics era? This article provides a brief overview of spatial biology…

Multiplexed Cell DIVE imaging to characterize the spatial landscape in Human Alzheimer’s Cortical Tissue

Probing Human Alzheimer's Cortical Section using Spatial Multiplexing

Alzheimer’s disease (AD) is the most common neurodegenerative disease and is characterized by the progressive decline of cognitive function. Spatial profiling of AD brain may reveal cellular…

Cell DIVE开放式超多重免疫荧光成像如何赋能空间生物学

空间生物学和多重成像工作流程在免疫肿瘤学研究中变得越来越重要。许多研究人员即使使用有效的工具和方案，也很难提高研究效率。我们将介绍研究人员如何利用开放式超多重免疫荧光的适应性，将 IBEX 成像与Cell DIVE 相结合，创造了一种名为 Cell DIVE-IBEX 的技术。它让这些研究人员能够调整现有的技术和试剂，并获得Cell DIVE 在其免疫肿瘤学研究中的可扩展性。
