Abstract Immune checkpoint inhibitors have revolutionized cancer treatment, producing a durable response consistent with immunologic memory in a subset of patients. However, the majority of patients demonstrate innate or acquired resistance that must be characterized and overcome to induce successful treatment. Advancements in human reverse translation and scaled in vivo CRISPR screening have uncovered novel molecular and genomic correlates of resistance, and promising druggable mechanisms - driven by highly complex interactions between tumor cells and the immune system.

Résumé :

Creutzfeldt-Jakob disease (CJD) is a brain disorder that causes dementia. It forms part of a set of animal and human diseases called prion disorders. Symptoms of Creutzfeldt-Jakob disease can resemble those of Alzheimer’s disease. This disease is always fatal, and most patients do not survive beyond a year. Myoclonus, vision problems, brain and pyramidal/extrapyramidal symptoms, and changes in cognitive function and cognitive abilities are seen as manifestations. We present a case of a 65-year-old woman complaining of rapidly progressive dementia, which was followed by the slowness of movement

Such approaches can be a limitation in IO drug discovery and development as de novo development of antibodies is associated with long lead times, high costs, and high failure rates.

Abstract Pancreatic ductal adenocarcinoma (PDAC) is most often diagnosed at an advanced stage. Newly diagnosed patients therefore have a dismal five-year survival rate of 11%. However, PDAC progresses from pre-invasive pancreatic intraepithelial neoplasia (PanIN) over at least a decade. Throughout this transition, the tissue microenvironment becomes increasingly immunosuppressive. Early PanINs may therefore be more amenable to immune-based interception strategies; however, little is known about the pre-malignant lesion immune microenvironment in PDAC.

Abstract Hematopoietic progenitor kinase 1 (HPK1, mitogen-activated kinase kinase kinase kinase 1 [MAP4K1]), a cytosolic STE20 ser/thr kinase from the germinal center family of kinases, regulates the function of diverse immune populations including T cells, B cells, and dendritic cells. In T cells, activated HPK1 regulates T cell receptor (TCR) signaling by phosphorylating the adaptor protein SLP76 on Ser376, which induces the association of SLP76 with 14-3-3 proteins. This SLP76/14-3-3 complex leads to its disassociation from the TCR signalosome, resulting in reduced downstream TCR signaling.

Prion diseases, which can manifest by transmissible, sporadic or genetic etiologies, share several common features, such as a fatal neurodegenerative outcome and the aberrant accumulation of proteinase K (PK)-resistant PrP forms in the CNS. In infectious prion diseases, such as scrapie in mice, prions first replicate in immune organs, then invade the CNS via ascending peripheral tracts, finally causing death. Accelerated neuroinvasion and death occurs when activated prion-infected immune cells infiltrate into the CNS, as is the case for scrapie-infected mice induced for experimental autoimmune

This ICD induction is thought to be crucial for enhancing the efficacy of immunotherapies.

To better understand TME dynamics and represent them consistently and interpretably, we developed a framework for immunophenotyping using disparate immuno-oncology (IO) transcriptional “fingerprints” as part of the AbbVie IO

Abstract Tumors harbor a complex ecosystem of malignant, immune, and stromal cells. While malignant cells dictate much of the tumor biology, there is evidence that the tumor microenvironment (TME) also plays a major role in disease etiology. Given the complexity and abundance of the TME cellular composition, investigating the role of immune cell types will yield novel biomarkers for tumor progression and response to therapies. The role of B cells as a prognostic biomarker remains elusive. For instance, infiltrating B cells in CRC have both positive and negative prognostic value. Thus, a scalab

Abstract Immune-based therapies that induce tumor regression are often accompanied by immune-related adverse events (irAEs) which can occasionally present with severe and lethal symptoms. Currently, there are no well-defined preventative approaches to uncouple anti-tumor immunity from irAEs. Currently approved immunotherapies include agents that activate T cell responses, such as antibodies blocking immune checkpoints and infusion of tumor-derived, T cell receptor-transgenic or chimeric antigen receptor-modified T cells.

Abstract Introduction: Metastatic outgrowth and colonization requires that disseminated tumor cells simultaneously compensate for alterations in nutrient availability, counteract oxidative stress, and evade host innate and adaptive immune surveillance. The mechanistic underpinnings of how these vital processes are coordinated is not understood. Experimental procedures: Using intrasplenic injection (liver metastases) and tail vein injection (lung metastases), we employed a gain-of-function cDNA screen in mice to identify regulators of colonization. In doing so, we identified GCN1 signaling as i

Selecting suitable and cost-effective experimental models for developing and validating immunotherapies is one of the major obstacles researchers face today. To overcome this, patient-derived tumor models are of increasing interest because they can better recapitulate many of the properties and the heterogeneity exhibited by the tumor microenvironment at a relatively low cost.

Since time immemorial animals have been a major source of human infectious disease. Certain infections like rabies are recognized as zoonoses caused in each case by direct animal–to–human transmission. Others like measles became independently sustained with the human population so that the causative virus has diverged from its animal progenitor. Recent examples of direct zoonoses are variant Creutzfeldt–Jakob disease arising from bovine spongiform encephalopathy, and the H5N1 avian influenza outbreak in Hong Kong. Epidemics of recent animal origin are the 1918–1919 influenza pandemic, and acqu

Abstract Addressing the limited responsiveness to immune checkpoint blockade (ICB) in human cancers remains a critical challenge. Efforts over the past two decades have primarily focused on enhancing CD8 T cell function and preventing their exhaustion. However, less attention has been given to understanding the molecular mechanisms that contribute to the immunosuppressive tumor microenvironment (TME), which impedes CD8 T cell infiltration and fosters ICB resistance. The TME in ICB-resistant tumors is characterized by Transforming Growth Factor beta (TGF-β) cytokine signaling, leading to a fibr

Abstract Cutaneous melanoma is the most fatal skin cancer; resistance to targeted therapies contributes to poor prognosis. In some cases, resistance arises from pre-existing tumor heterogeneity, which allows subpopulations of drug-tolerant cells with distinct transcriptional states to survive in the presence of drug. The loss of SOX10, a lineage-specific transcription factor, is known to drive melanoma phenotype switching from a proliferative to an invasive drug-tolerant state. Here, we found that knocking out SOX10 in human and mouse melanoma cell lines leads to the upregulation of transgluta
