Syngeneic models are a valuable tool for evaluating the anti-tumour effects of a variety of cancer immunotherapies. To optimise model use, and truly understand the interplay between immunomodulation and anti-tumour phenotype, in depth syngeneic characterisation is required.

We’ve characterised the syngeneic models used in our MuScreen™ in vivo screening platform. This immunoprofiling includes capturing the dynamic changes of immune cell presence and infiltration within different compartments of tumour-bearing mice, after treatment with checkpoint inhibitors.

The resulting datasets reveal changes in immune profile relative to anti-tumour response, and can help guide strategic decisions on preclinical model, as well as combinatorial drug selection.

Read this Poster to Discover:

• That comprehensive characterisation studies show variable basal level immune cell tumour infiltration for each syngeneic model, as well as high variation of immunophenotypic changes in response to PD-1 blockade for individual mice
• How variable levels of immune cell infiltration are observed in each of the syngeneic models, which could guide model selection based on MOA or proposed target immune cells
• That a trend of meaningful immunomodulatory changes are observed in models with robust tumour growth inhibition following aPD-1 treatment, but no clear pattern of immunoprofiling changes are seen in less responsive or resistant models
