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.

Sneha Ramakrishna
Assistant Professor of Pediatrics (Hematology/Oncology)
BioSneha Ramakrishna obtained her B. A. from the University of Chicago and her M.D. from the Cleveland Clinic Lerner College of Medicine at Case Western Reserve University. In medical school, through the Howard Hughes Medical Research Scholar Award, she joined Dr. Crystal Mackall’s laboratory, where she designed and developed various GD2 CAR-Ts and tested them in preclinical models. During her residency training in Pediatrics at the Children’s Hospital of Philadelphia, she cared for some of the first patients treated with CD19 CAR T cells, learning the power of this therapy first-hand. During her fellowship in Pediatric Hematology/Oncology at the Johns Hopkins/National Cancer Institute combined program, she worked with Dr. Terry Fry. She evaluated the mechanism of CD22 CAR T cell relapse in patients by developing an antigen escape model and establishing a deeper understanding of the effects of antigen density on CAR-T phenotype, expansion, and persistence (Fry…Ramakrishna…Mackall Nat Med, 2018; Ramakrishna, et al., Clinical Cancer Research, 2019). Since arriving at Stanford, Dr. Ramakrishna leads an interdisciplinary team that designs, develops, and successfully implements a robust correlative science platform for our novel CAR-T therapies. Analyzing patient samples from our first-in-human GD2 CAR-T trial (NCT04196413) treating a universally fatal cancer, diffuse midline glioma (DMG), we identified that intracerebroventricular CAR-T administration correlates with enhanced pro-inflammatory cytokines and reduced immunosuppressive cell populations in cerebrospinal fluid as compared to intravenous CAR-T administration (Majzner*, Ramakrishna*, et al., Nature 2022 *co-first authors). Her research program evaluates unique sets of patient samples using novel single-cell immune profiling to identify the drivers of CAR-T success or failure. Building on these findings, her team assesses approaches to enhance CAR-T efficacy and translate these findings to the clinic.
Clinically, Dr. Ramakrishna cares for children with solid tumors and treats hematologic, solid, and brain tumor pediatric patients with CAR T cell therapies in the Cancer Cellular Therapies program.
