Abstract We have developed NetPath as a resource of curated human signaling pathways. As an initial step, provides detailed maps number immune pathways, which include approximately 1,600 reactions annotated from the literature and more than 2,800 instances transcriptionally regulated genes - all linked to over 5,500 published articles. anticipate become consolidated for pathways that should enable systems biology approaches.
