Fc-dependent depletion of tumor-infiltrating regulatory T cells co-defines the efficacy of anti–CTLA-4 therapy against melanoma
Anti–CTLA-4 antibody induces selective depletion of T reg cells within tumor lesions in a manner that is dependent on the presence of Fc gamma receptor-expressing macrophages within the tumor… Expand

Clonal neoantigens elicit T cell immunoreactivity and sensitivity to immune checkpoint blockade
The cellular ancestry of tumor antigens One contributing factor in antitumor immunity is the repertoire of neoantigens created by genetic mutations within tumor cells. Like the corresponding… Expand

Blockade of CTLA-4 on both effector and regulatory T cell compartments contributes to the antitumor activity of anti–CTLA-4 antibodies
Cytotoxic T lymphocyte–associated antigen 4 (CTLA-4) is a critical negative regulator of immune responses. Uniquely among known inhibitory receptors, its genetic ablation results in a fulminating and… Expand

CD40/CD154 interactions at the interface of tolerance and immunity.
Development of the acquired immune response is dependent on the signaling of CD40 by its ligand, CD154. These molecules govern both the magnitude and quality of humoral- and cell-mediated immunity. A… Expand

Cyclooxygenase-Dependent Tumor Growth through Evasion of Immunity
Summary The mechanisms by which melanoma and other cancer cells evade anti-tumor immunity remain incompletely understood. Here, we show that the growth of tumors formed by mutant BrafV600E mouse… Expand

Tumor-reactive CD4+ T cells develop cytotoxic activity and eradicate large established melanoma after transfer into lymphopenic hosts
Adoptive transfer of large numbers of tumor-reactive CD8+ cytotoxic T lymphocytes (CTLs) expanded and differentiated in vitro has shown promising clinical activity against cancer. However, such… Expand

CTLA4 blockade and GM-CSF combination immunotherapy alters the intratumor balance of effector and regulatory T cells.
CTL-associated antigen 4 (CTLA4) blockade releases inhibitory controls on T cell activation and proliferation, inducing antitumor immunity in both preclinical and early clinical trials. We examined… Expand

Principles and use of anti-CTLA4 antibody in human cancer immunotherapy.
Cytotoxic T lymphocyte antigen-4 has become recognized as one of the key negative regulators of adaptive immune responses, having a central role in the maintenance of peripheral tolerance and in… Expand

Cutting Edge: Contact-Mediated Suppression by CD4+CD25+ Regulatory Cells Involves a Granzyme B-Dependent, Perforin-Independent Mechanism1
CD4+CD25+ regulatory T cells (Treg) are potent immunosuppressive cells that are pivotal in the regulation of peripheral tolerance. In this report, we identify granzyme B (GZ-B) as one of the key… Expand

Phylogenetic ctDNA analysis depicts early stage lung cancer evolution
The early detection of relapse following primary surgery for non-small-cell lung cancer and the characterization of emerging subclones, which seed metastatic sites, might offer new therapeutic… Expand
