About

Harvey Cantor is a Professor of Immunology at Harvard Medical School, based at the Dana Farber Cancer Institute. His lab studies the development and function of T-cell subsets, focusing on how different T-cell lineages recognize MHC class I and II molecules and mediate distinct immunological functions. Early research indicated that the thymus gives rise to two major T-cell lineages, and his work has contributed to understanding cell-mediated immunity, natural killer cells, and regulatory and effector lineages within the CD8+ T-cell subset. Current research in his lab includes defining regulatory T cell lineages that inhibit autoimmune disease and regulate anti-viral and anti-tumor immunity. His team has studied the role of the Helios transcription factor in maintaining Treg stability and self-tolerance. Additionally, his research involves studying non-classical CD8+ T-cells recognizing viral peptides presented by MHC-E molecules to understand their role in anti-viral and anti-tumor immunity, especially in the context of immune evasion by tumors. His work also explores genetic and epigenetic factors controlling the tumor microenvironment and investigates the immune system's contribution to Alzheimer's Disease. His research aims to enhance understanding of cellular and molecular mechanisms to improve vaccine design and immunotherapy.

  A wide variety of suppressive pathways have been investigated in efforts to understand the basis for immune tolerance. Although the contribution of CD4+ regulatory T cells (Tregs) to self-tolerance has been extensively studied, less attention has been given to CD8+ Tregs. Here we review recent insights into the development, function, and potential clinical applications of this regulatory subset. We focus on CD8+ Tregs that recognize self-peptides associated with MHC-Ib products and that express Ly49/KIR (killer cell immunoglobulin-like receptor) coinhibitory receptors. Recent analyses of their T cell receptor repertoire, thymic differentiation, and mechanism of suppression are summarized. Identification of the human homolog of these cells has suggested new strategies for CD8+ Treg-dependent immunotherapy for autoimmune disease and cancers.

• The Greater Omentum: A Proposed Mechanism of Movement in the Abdomen

  Clinical Anatomy · 2025-12-04

  article

  The greater omentum is a thin sheet-like abdominal organ sandwiched between the anterior abdominal wall and the intestines. It possesses adipose deposits, an epiploic vascular system, arcade-like vascular loops, and a significant number of omental milky spots, the name given to the immune/lymphatic cell clusters residing in its tissues. Observational and experimental evidence confirms that the omentum moves toward inflamed abdominal organs and surgical sites and invades via vascular and fibrous tissues, in order to isolate the area and launch an immune response. Correlated to this, direct evidence of omental growth in response to inflammatory chemokine stimuli has also been established. Further, it has been demonstrated that the metabolic activity of the milky spots, when engaged in such a response, increases 10-20 fold, along with increases in the number and size of the spots. A mechanism of chemotaxis has yet to be identified, but it is clear that the omentum is an important immunological organ that responds to inflammation and infection in the abdomen, both cellularly and physically. We propose that the blood vessels of the omentum act as a multi-pronged hydrostat system, engorging themselves and their capillaries with blood, responding to an inflammatory trigger like inflated fire hoses, and extending the organ across the abdomen. Thus, the omentum represents an unique mobile immune system that we believe warrants further focus in anatomical, clinical, immunological, and biomechanical research.

• Growth, genetic, and phenotypic responses of Chlamydomonas and Arabidopsis to varying concentrations of and times of exposure to deoxynivalenol (DON)

  2024-10-11

  article1st authorCorresponding

  Fusarium head blight (FHB) is a deadly fungal disease that affects large quantities of wheat and barley each year. The current study found that the knocking out of a gene in algae led to decreased resistance to a toxin produced by FHB (DON) while its overexpression led to increased resistance; this overexpression resulted in some upregulation of downstream genes, particularly when DON was not added. Phenotyping revealed that DON led to chloroplast rupture, and a gene coding for a sulfur transport protein in the Arabidopsis plant was quickly and greatly upregulated in response to DON while other genes were not.

• Associations of cortical <i>SPP1</i> and <i>ITGAX</i> with cognition and common neuropathologies in older adults

  Alzheimer s & Dementia · 2023-09-19 · 33 citations

  articleOpen access

  INTRODUCTION: cells is known to be associated with microglia activation and neuroinflammatory diseases. As most studies rely on mouse models, we investigated these genes and proteins in the cortical brain tissue of older adults and their role in Alzheimer's disease (AD) and related disorders. METHODS: We leveraged protein measurements, single-nuclei, and RNASeq data from the Religious Orders Study and Rush Memory and Aging Project (ROSMAP) of over 1200 samples for association analysis. RESULTS: Expression of SPP1 and its encoded protein osteopontin were associated with faster cognitive decline and greater odds of common neuropathologies. At single-cell resolution, integrin subunit alpha X (ITGAX) was highly expressed in microglia, where specific subpopulations were associated with AD and cerebral amyloid angiopathy. DISCUSSION: The study provides evidence of SPP1 and ITGAX association with cognitive decline and common neuropathologies identifying a microglial subset associated with disease.

• Definition of the contribution of an Osteopontin-producing CD11c ⁺ microglial subset to Alzheimer’s disease

  Proceedings of the National Academy of Sciences · 2023-02-02 · 55 citations

  articleOpen accessSenior author

  Alzheimer’s disease (AD) is the most common form of incurable dementia and represents a critical public health issue as the world’s population ages. Although microglial dysregulation is a cardinal feature of AD, the extensive heterogeneity of these immunological cells in the brain has impeded our understanding of their contribution to this disease. Here, we identify a pathogenic microglial subset which expresses the CD11c surface marker as the sole producer of Osteopontin (OPN) in the 5XFAD mouse model of AD. OPN production divides Disease-Associated Microglia (DAM) into two functionally distinct subsets, i.e., a protective CD11c + OPN − subset that robustly ingests amyloid β (Aβ) in a noninflammatory fashion and a pathogenic CD11c + OPN + subset that produces proinflammatory cytokines and fails to ingest significant amounts of Aβ. Genetic ablation of OPN or administration of monoclonal anti-OPN antibody to 5XFAD mice reduces proinflammatory microglia, plaque formation, and numbers of dystrophic neurites and results in improved cognitive function. Analysis of brain tissue from AD patients indicates that levels of OPN-producing CD11c + microglia correlate strongly with the degree of cognitive deficit and AD neuropathology. These findings define an OPN-dependent pathway to disease driven by a distinct microglial subset, and identify OPN as a novel therapeutic target for potentially effective immunotherapy to treat AD.

• A narrow T cell receptor repertoire instructs thymic differentiation of MHC class Ib–restricted CD8+ regulatory T cells

  Journal of Clinical Investigation · 2023-11-07 · 13 citations

  articleOpen accessSenior author

  Although most CD8+ T cells are equipped to kill infected or transformed cells, a subset may regulate immune responses and preserve self-tolerance. Here, we describe a CD8 lineage that is instructed to differentiate into CD8 T regulatory cells (Tregs) by a surprisingly restricted set of T cell receptors (TCRs) that recognize MHC-E (mouse Qa-1) and several dominant self-peptides. Recognition and elimination of pathogenic target cells that express these Qa-1-self-peptide complexes selectively inhibits pathogenic antibody responses without generalized immune suppression. Immunization with synthetic agonist peptides that mobilize CD8 Tregs in vivo efficiently inhibit antigraft antibody responses and markedly prolong heart and kidney organ graft survival. Definition of TCR-dependent differentiation and target recognition by this lineage of CD8 Tregs may open the way to new therapeutic approaches to inhibit pathogenic antibody responses.
