Garcia-Beltran Lab

NK cell biology, immune/cellular therapy

Lab Overview

The Garcia-Beltran Lab is devoted to fundamental and translational immunology. Our fundamental research focuses on defining the molecular pathways that govern target-cell recognition and killing by natural killer (NK) cells, critical first-line immune defenders against viral infections and cancer. In parallel, our translational research leverages synthetic biology and genome engineering to develop NK cell-based immune and cellular therapies for a broad range of human diseases.

In our laboratory, we use CRISPR-based genetic screens to identify regulators of target-cell susceptibility and resistance to NK-cell killing and to uncover molecular pathways that control NK-cell survival, migration, and effector functions. We incorporate these discoveries into rationally designed synthetic receptors and genome-engineering strategies to generate next-generation NK-cell therapies against hematologic and solid malignancies, with a particular emphasis on enhancing persistence, homing, tumor infiltration, antigen recognition, and cytotoxicity. These approaches are evaluated using complex in vitro systems and humanized mouse models. In parallel, we investigate how viruses including HIV-1, SARS-CoV-2, and mpox manipulate host-cell biology to evade NK-cell recognition and broader immune surveillance.

About

Dr. Garcia-Beltran is a physician-scientist focused on developing novel, accessible immunotherapies against viral infections and cancer. He is originally from Puerto Rico and earned a bachelor’s degree in Chemistry from the University of Puerto Rico–Río Piedras before moving to Boston, Massachusetts to join the Harvard-MIT MD/PhD Program in 2010. He earned his PhD in Immunology from Harvard University in 2016, where he studied the role of natural killer (NK) cells in HIV-1 infection, and his MD through the Harvard-MIT Health Sciences and Technology (HST) Program in 2018. He subsequently completed residency training in Clinical Pathology and subspecialty fellowship training in Transfusion Medicine at Massachusetts General Hospital (MGH), while conducting postdoctoral research on SARS-CoV-2 infection and vaccines, NK-cell biology, and cellular therapies. He is currently an Assistant Professor at Harvard Medical School and leads his laboratory at the Ragon Institute of Mass General, MIT, and Harvard, where his research applies translational immunology, synthetic biology, and genome engineering to harness NK cells for the development of next-generation immunotherapies.
