In a study of 30 renal transplant patients, around 52-56 years of age, who took part in an experiment involving the pairing of immunosuppressive drugs with a gustatory stimulus, researchers found that the stimulus increased the efficacy of the immunosuppressive medication, such that T cell proliferative capacity was significantly reduced compared with baseline T cell measures under routine drug intake in subsequent placebo testing, suggesting that learned immunosuppressive behavior might help to improve immunopharmacological treatment strategies.
