LIANA - a LIgand-receptor ANalysis frAmework

LIANA: a LIgand-receptor ANalysis frAmework

LIANA is a Ligand-Receptor inference framework that enables the use of any LR method with any resource. This is its faster and memory efficient Python implementation, an R version is also available here.

For further information please check LIANA's documentation, and also tutorial.

Methods

The methods implemented in this repository are:

• CellPhoneDBv2
• NATMI
• Connectome
• SingleCellSignalR
• CellChat (+)
• 1-vs-rest expression LogFC score
• Geometric Mean - ligand-receptor geometric mean with pvalues obtained via the permutation approach implemented by CellPhoneDBv2
• rank_aggregate of the predictions calculated with the RobustRankAggregate method

(+) A resource-independent adaptation of the CellChat LR inference functions.

Ligand-Receptor Resources

The following CCC resources are accessible via this pipeline:

• Consensus ($)
• CellCall
• CellChatDB
• CellPhoneDB
• Ramilowski2015
• Baccin2019
• LRdb
• Kiroauc2010
• ICELLNET
• iTALK
• EMBRACE
• HPMR
• Guide2Pharma
• ConnectomeDB2020
• CellTalkDB
• MouseConsensus (#)

($) LIANA's default Consensus resource was generated from several expert-curated resources, filtered to additional quality control steps including literature support, complex re-union/consensus, and localisation.

(#) Consensus Resource converted to murine homologs.
