About CD8 ImmunoPET

CD8 ImmunoPET is a 89Zr-labelled minibody that has been designed to bind to the CD8 receptor on human T cells for quantitative, non-invasive PET imaging of CD8+ T cells. CD8+ T cells are the main effector cells involved in the immune response against tumour cells induced by immunotherapies and they also play a key role in multiple autoimmune diseases. As such, quantitative imaging of CD8+ T cells is currently being researched to determine whether it may be used to diagnose the immune status of a patient, to measure the efficacy of immunotherapies and predict patient outcomes.
