Figure 1: Polyfunctional overview of analyzed CD8+ TILs samples, showing samples from responders have 2x more polyfunctional cells than untreated samples, and 5x higher polyfunctional strength. (Zhou 2017)
Figure 2: CD8+ TILs single-cell secretion intensities of each cytokine. The percentage of cells strongly secreting at least one cytokine in responding patients’ samples is five times higher (21.2%) than in nonresponding patients’ samples (3.8%), and twice as high as in untreated patients’ samples (10.5%).

Local Dream Team Develops Cancer Treatment That's Saving Lives. A dream team of Caltech and UCLA scientists and doctors have created a treatment that's giving hope to cancer patients who once had none. The medication was developed by chemistry professor James Heath and his lab at Caltech in Pasadena, who work day and night, to help UCLA oncologist Antoni Ribas try to cure his incurable cancer patients.
