Computational identification of targets for CAR-T cell therapy in AML

This repository contains all jupyter notebooks to reproduce the results of the single-cell data analysis from:

A. Gottschlich, M. Thomas, R. Grünmeier et al., "Single-cell transcriptomic atlas-guided development of chimeric antigen-receptor (CAR) T cells for the treatment of acute myeloid leukemia", Nature Biotechnology (2023).

The notebooks contain code for the following analyses:

  • Preprocessing and Analysis of AML datasets including query to reference mapping
  • Preprocessing and harmonization of single cell data across multiple organs using public datasets
  • Combining public databases to infer genes coding for surface- and druggable proteins as well as analysis of bulk sequencing data

Note that the analysis was done in python 3 using scanpy v.1.4.6 to 1.9.1 and anndata v.0.7.1 to 0.8.0 unless otherwise stated. Some functions may have changed when using other package versions. Additionally, numpy (v. 1.18.2+), pandas (v. 1.3.5+) and scipy (v. 1.4.1+) are required. Numeric results can vary depending on package versions and e.g. minor results. All scRNA-seq figures were plotted using matplotlib and seaborn.

Question about single cell data across multiple organs

Dear Professors,

Congratulations! Great work on NBT! I am interested in the scRNA-seq-based screening algorithm of your published manuscript. According to your code, I installed “sfaira” package but found that some code (sfaira.data.human.DatasetGroupKidney) did not work. I want to know which version of "sfaira" used in your data procession? And could you provide the processed h5ad file of the single cell data across multiple organs? Thank you very much for your kindly help!!!

How were thresholds chosen?

Great work and thank you for providing such detailed code!

I am curious on how you chose the threshold when filtering out genes based on expression in your COOTA data clusters? Specifically, how you chose the 2% threshold?

And, was there any optimization of this threshold in terms of what minimal expression in vital cell types would be deemed "safe"?

Thanks
