We have developed a methodology of cyclic multiplex fluorescent immunohistochemistry on human postmortem brain sections followed by an image analysis and machine learning pipeline that enables a deep morphological characterization of astrocytes and microglia in the Alzheimer’s brain.
To run our code, please install the following dependencies:
Additional required libraries are specified in each script. Image segmentation was performed with the FIJI distribution of the open-source Java-based image analysis program ImageJ.1,2 Convolutional neural networks (CNN) were constructed using the PyTorch open-source deep learning library in the Python programming language (version 3.8.5).3 Unless otherwise indicated, all other analyses were performed in the R programming language and statistical computing environment (version 4.1.0).
