Over the past 6 years, this growing interest has led to the development of more than 100 bioinformatics tools and nearly 50 resources, primarily in the form of ligand-receptor databases. These tools vary widely in their requirements, scoring approaches, ability to infer inter- and\/or intra-cellular communication, assumptions, and limitations. Similarly, cell\u2013cell communication resources differ in many aspects, mainly in the number of annotated interactions, species coverage, and their focus on inter-cellular signaling or both inter- and intra-cellular communication. This abundance and diversity create challenges in identifying compatible and suitable tools and resources to meet specific user needs. In this collaborative effort, we aim to provide a comprehensive report on the current state of cell\u2013cell communication analysis derived from single-cell or spatial transcriptomics data. The report reviews existing methods and resources, addressing all relevant aspects from the user\u2019s perspective. It also explores current limitations, pitfalls, and unresolved issues in cell\u2013cell communication inference, offering an aggregated analysis of the existing literature on the topic. Furthermore, we highlight potential future directions in the field and consolidate the collected knowledge into CCC-Catalog (https:\/\/sysbiobig.gitlab.io\/ccc-catalog), a centralized web platform designed to serve as a hub for bioinformaticians and researchers interested in cell\u2013cell communication inference.<\/jats:p>","DOI":"10.1093\/bib\/bbaf280","type":"journal-article","created":{"date-parts":[[2025,6,27]],"date-time":"2025-06-27T20:18:22Z","timestamp":1751055502000},"source":"Crossref","is-referenced-by-count":24,"title":["Advances
