M Bruce MacIver
Professor (Research) of Anesthesiology, Perioperative and Pain Medicine, Emeritus
Current Research and Scholarly InterestsWe study drug effects on the nervous system. Cellular, synaptic and molecular drug actions are investigated using electrophysiological and pharmacological tools in cortical/hippocampal brain slice preparations. We are also interested in mechanisms of neuronal integration and synchronization, especially related to patterns of EEG activity seen in vivo and in brain slices.

Crystal Mackall
Ernest and Amelia Gallo Family Professor and Professor of Pediatrics and of Medicine
Current Research and Scholarly InterestsRecent clinical studies, by us and others, have demonstrated that genetically engineered T cells can eradicate cancers resistant to all other therapies. We are identifying new targets for these therapeutics, exploring pathways of resistance to current cell therapies and creating next generation platforms to overcome therapeutic resistance. We have discovered novel insights into the biology of human T cell exhaustion and developed approaches to prevent and reverse this phenomenon.
