Imatinib potentiates antitumor T cell responses in gastrointestinal stromal tumor through the inhibition of Ido, 
Vinod P Balachandran, et al. Nature Medicine17 (2011) 


I would like to hilight this paper to our readership, as many of your are involved in the design of clinical trials and selection of potential biomarkers. This report is one of a handful of high impact papers that report the coperative role that inflammatory infiltrate and non cell autonomous effectors play in modulating response to established agents. This study demonstrates an interesting immunological mechanism of Imatininb  that contributes to the antitumor effect in a Gastrointestinal Stromal Tumor (GIST) mouse model. Inflammatory infiltrate is a known finding in GIST specimens (including intratumoral CD8+ Tcells, Treg cells and macrophages). Acording to the authors, Imatinib activates CD8+ T cells and induces Treg cells apoptosis within the tumor. Imatinib is therefore able to reduce the expression of 2,3-dioxygenase (Ido) of tumor cells. Ido enzyme is involved in the catayzation of immunosuppressive metabolites from tryptophan and therefore mediates downstream immunological response. Interestingly Imatininb resistant tumors, generally as a result of a second KIT mutation, restore the overexpression of IDO and combination of Imatinib with CTLA-4 blockade (a well established immunotherapeutic strategy) act synergistically. This insight provides some hints on something we have been suspecting for a long time. It is easy to predict consequences for rational design of combination therapies and strategies to overcome resistance in Imatinib resistant tumors.TweetShare

Imatinib potentiates antitumor T cell responses in gastrointestinal stromal tumor through the inhibition of Ido, 
Vinod P Balachandran, et al. Nature Medicine17 (2011) 


I would like to hilight this paper to our readership, as many of your are involved in the design of clinical trials and selection of potential biomarkers. This report is one of a handful of high impact papers that report the coperative role that inflammatory infiltrate and non cell autonomous effectors play in modulating response to established agents. This study demonstrates an interesting immunological mechanism of Imatininb  that contributes to the antitumor effect in a Gastrointestinal Stromal Tumor (GIST) mouse model. Inflammatory infiltrate is a known finding in GIST specimens (including intratumoral CD8+ Tcells, Treg cells and macrophages). Acording to the authors, Imatinib activates CD8+ T cells and induces Treg cells apoptosis within the tumor. Imatinib is therefore able to reduce the expression of 2,3-dioxygenase (Ido) of tumor cells. Ido enzyme is involved in the catayzation of immunosuppressive metabolites from tryptophan and therefore mediates downstream immunological response. Interestingly Imatininb resistant tumors, generally as a result of a second KIT mutation, restore the overexpression of IDO and combination of Imatinib with CTLA-4 blockade (a well established immunotherapeutic strategy) act synergistically. This insight provides some hints on something we have been suspecting for a long time. It is easy to predict consequences for rational design of combination therapies and strategies to overcome resistance in Imatinib resistant tumors.TweetShare
