R data suggest that T-cell reactivity against tumor-specific neoantigens may be central to the clinical efficacy of cancer immunotherapy. The development of personalized vaccines designed to boost T-cell reactivity against patient specific neo-antigens has been proposed largely on the basis of these findings. Work from several groups has demonstrated that(More)
The development of targeted inhibitors, like vemurafenib, has greatly improved the clinical outcome of BRAF(V600E) metastatic melanoma. However, resistance to such compounds represents a formidable problem. Using whole-exome sequencing and functional analyses, we have investigated the nature and pleiotropy of vemurafenib resistance in a melanoma patient(More)
BACKGROUND Advances in fluorescence microscopy and mouse transgenesis have made it possible to image molecular events in living animals. However, the generation of transgenic mice is a lengthy process and intravital imaging requires specialized knowledge and equipment. Here, we report a rapid and undemanding intravital imaging method using generally(More)
Importance Checkpoint blockade therapy targeting cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and the programmed cell death protein 1 pathways (PD-1/PD-L1) have achieved success in treating a number of malignancies. However, only a subset of patients responds to these therapies, and optimization of patient selection for treatment is imperative to(More)
The induction of mixed hematopoietic chimerism following allogeneic stem cell transplantation is a potential treatment modality for numerous nonmalignant diseases and generates a robust state of donor-specific tolerance. However, despite several promising results in murine studies, the translation to nonhuman primate models and clinical trials has proven to(More)
Cytotoxic T-cell immunity directed against melanosomal differentiation antigens is arguably the best-studied and most prevalent form of tumor-specific T-cell immunity in humans. Despite this, the role of T-cell responses directed against melanosomal antigens in disease progression has not been elucidated. To address this issue, we have related the presence(More)
