LIANA+ is a scalable framework that integrates and extends existing methods and knowledge to study cell-cell communication in single-cell, spatially-resolved, and multi-modal omics data. It is part of the scverse ecosystem, and relies on AnnData & MuData objects as input.
We welcome suggestions, ideas, and contributions! Please use do not hesitate to contact us, or use the issues or the LIANA+ Development project to make suggestions.
- LIANA's basic tutorial in dissociated single-cell data
-
Learn spatially-informed relationships with MISTy across (multi-) views.
-
Estimate local spatially-informed bivariate metrics. This tutorial shows how to estimate local spatially-informed bivariate metrics, such as the spatially-informed Pearson correlation coefficient or Cosine similarity.
-
Hypothesis-testing for CCC with PyDeSeq2 that also shows the inference of causal intracellular signalling networks, downstream of CCC events.
-
Multicellular programmes with MOFA. Using MOFA to obtain coordinates gene expression programmes across samples and conditions, as done in Ramirez et al., 2023.
-
LIANA with MOFA. Using MOFA to infer intercellular communication programmes across samples and conditions, as initially proposed by Tensor-cell2cell.
-
LIANA with Tensor-cell2cell to extract intercellular communication programmes across samples and conditions. Extensive tutorials combining LIANA & Tensor-cell2cell are available here.
- We also refer users to the Cell-cell communication chapter in the best-practices guide from Theis lab. There we provide an overview of the common limitations and assumptions in CCC inference from (dissociated single-cell) transcriptomics data.
