Pan-cancer T cell atlas links a cellular stress response state to immunotherapy resistance
Tumor-infiltrating T cells offer a promising avenue for cancer treatment, yet their states remain to be fully characterized. Here we present a single-cell atlas of T cells from 308,048 transcriptomes…

Senescence and senotherapies in biliary atresia and biliary cirrhosis
Background: Premature senescence occurs in adult hepatobiliary diseases and worsens the prognosis through deleterious liver remodeling and hepatic dysfunction. Senescence might also arises in biliary atresia (BA), the first cause…

Spatial transcriptomics of murine bone marrow megakaryocytes at single cell resolution
Background: While megakaryocytes are known for making platelets, recent single cell RNA sequencing data have revealed subpopulations of megakaryocytes with predicted immunoregulatory and bone marrow niche-supporting roles. Although these studies…

Nodal reactive proliferation of monocytoid B-cells may represent atypical memory B-cells
Background: Reactive lymphadenopathies such as toxoplasmosis and cytomegalovirus lymphadenitis are associated with monocytoid cell proliferation. Monocytoid cells are B-lymphocytes with an undetermined subset. Methods: Using digital spatial profiling whole transcriptome…

Role of MXRA8 in Ross River Virus Disease Pathogenesis
Arthritogenic alphaviruses such as Ross River virus (RRV) and Chikungunya virus (CHIKV) are responsible for large-scale epidemics that cause debilitating acute and chronic musculoskeletal diseases. MXRA8 was recently discovered as…

Insights from Immunoproteomic Profiling of a Rejected Full Face Transplant
Vascularized composite allografts (VCAs) of faces and extremities are subject to chronic rejection that is incompletely understood. Here we report on immunoproteomic evaluation of a full facial VCA removed 88…

Vascular mechanisms of post-COVID-19 conditions: Rho-kinase is a novel target for therapy
Background: In post-coronavirus disease-19 (post-COVID-19) conditions (long COVID), systemic vascular dysfunction is implicated, but the mechanisms are uncertain, and the treatment is imprecise. Methods and results: Patients convalescing after hospitalization…

Mapping the Immune Cell Microenvironment with Spatial Profiling in Muscle Tissue Injected with the Venom of Daboia russelii
Pathological and inflammatory events in muscle after the injection of snake venoms vary in different regions of the affected tissue and at different time intervals. In order to study such…

Identification of a protein expression signature distinguishing early from organising diffuse alveolar damage in COVID-19 patients
Diffuse alveolar damage (DAD) is the histological expression of acute respiratory distress syndrome and characterises lung pathology due to infection with SARS-CoV-2, and other respiratory pathogens of clinical significance. DAD…

Characterizing dermal transcriptional change in the progression from sun-protected skin to actinic keratosis
Understanding early tumorigenic events have obvious diagnostic and prognostic implications, particularly in the skin since this is the site of more US cancer diagnoses than any other organ (Rogers et…

Spatial transcriptomic characterization of COVID-19 pneumonitis identifies immune circuits related to tissue injury
Severe lung damage resulting from COVID-19 involves complex interactions between diverse populations of immune and stromal cells. In this study, we used a spatial transcriptomics approach to delineate the cells,…

Digital Spatial Profiling of Glomerular Gene Expression in Pauci-Immune Focal Necrotizing Glomerulonephritis
Pauci-immune focal necrotizing glomerulonephritis (piFNGN) involves asynchronous onset and progression of injurious lesions in biopsies. Pathologists can describe this heterogeneity within a biopsy, but translating the information into prognostic or…
