Determining the cellular mechanisms of diseases is a crucial requirement for understanding the causes and progression of diseases, predicting outcomes, and developing new treatments. Often relevant information, e.g. what cells are involved in a disease or what effects does a drug have on cells, is scattered across many papers and journals, which makes it difficult for researchers to be sure they have a complete picture. Using Elsevier’s automated text mining technology, we have created a new cell-centered database consisting of 850 000 facts captured from more than 24 million PubMed abstracts and 3.5 million full text articles for use in Pathway Studio. This database focused primarily on cellular aspects of immunology and immuno-oncology can be used to summarize and visualize published research, and to analyze experimental data.
