Mikael Pittet’s Lab

My laboratory performs a research program on the host immune response in vivo with the main goal to offer valuable new ways to combat cancer. We use various modalities, including in vivo imaging, to study where, when and how immune cells are produced, traffic, and mediate regulatory or effector functions. The studies make use of both genetic mouse models, which allow manipulations and analyses of mechanisms and causality, and human patient material, to ensure that the results are anchored in clinical correlates. This dual approach gives opportunities for discovery of novel contributions of the immune response to tumor progression, new biomarkers useful for diagnosis and prognosis, and novel targets for therapeutic intervention. Dr. Pittet directs Cancer Immunology Program at CSB and collaborates with several immunology programs at Harvard Medical School, Massachusetts General Hospital and Massachusetts Institute of Technology.

In vivo imaging of immune cells at different scales.
Imaging modalities include single photon emission computed
tomography – X-ray computed tomography (SPECT-CT), fluorescence
mediated tomography (FMT), microscopic fiber optics, and intravital
multiphoton microscopy (IVM).
