Gaining insights from internal and external/public
information sources is time and resource consuming
We have over 500 information solutions, we
don’t want 501. We want to consolidate our
solutions and increase information
discoverability.

The challenge is in putting together different
data sources and seeing patterns.

There is lots of locked away data—if that could
be made available, it would be highly valuable.

• Human γδ T cells lyse melanomas and other cancerous epithelial
cells in a perforin-mediated manner.
• Indeed, melanoma cell lines are subject to lysis by γδ T-cells,
which produce perforin and exhibit strong cytolytic activity upon
exposure.
• Both in vitro and in xenograft models, γδ lymphocyte-mediated
cytotoxicity against melanoma cells has been reported.
• Our results suggest that a natural immune response mediated by
γδ T lymphocytes may contribute to the immunosurveillance of
melanoma.
• Killer cell inhibitory receptors for MHC class I molecules regulate
lysis of melanoma cells mediated by gamma delta T
lymphocytes.

Provide greater context by adding cell processes to
each cell type
Allows more flexibility to address emerging topics
• More cell processes in the database provides greater breadth of information
• Find cell processes relevant to rare and cell types critical to biology of disease
• Automatic tracking of changes in literature trends to keep pace with evolving biology

describing its expression in melanoma
describing its immune system suppressive function

Discussion Summary
Let’s talk about a challenge with which we are all familiar -- technology has enabled exponential growth in the amount of available scientific literature and information. On the one hand that’s good, because with the right information we’re able to make more informed decisions and potentially accelerate our work. On the other hand, it’s made our work more challenging – how do you get to the “right information”? How do you easily combines sources, both internal and external, to compare and to see patterns? How do you keep up with what’s new and make an assessment of the research quality? In a nutshell, how do you make sense of all of it?
Today’s talk will highlight how integrated information can help facilitate critical workflows to:
Elsevier knowledgebase allows quick and comprehensive identification of novel immunotherapy targets for various types of cancer by summarization of multiple disparate articles published separately by cancer researchers and immunologists
Elsevier knowledgebase allows identification of new immunomodulatory drugs through drug repurposing
Compendium of immunomodulation mechanisms used by various cancers can be used to design new safer combinatorial immunotherapy treatments
Elsevier technology allows analysis of personalized patient data to select immunotherapy optimized for specific cancer mechanism
