Activin A-mediated polarization of cancer-associated fibroblasts and macrophages confers resistance to checkpoint immunotherapy in skin cancer
Purpose: Cemiplimab is approved for the treatment of locally advanced basal cell carcinomas (BCCs), however with mitigated results. We sought to interrogate the cellular and molecular transcriptional reprogramming underlying BCC…

Two Cases of Severe Pulmonary Toxicity from Highly Active Mesothelin-Directed CAR T Cells
Multiple clinical studies have treated mesothelin (MSLN)-positive solid tumors by administering MSLN-directed chimeric antigen receptor (CAR) T cells. Although these products are generally safe, efficacy is limited. Therefore, we generated…

Cerebellar axonopathy in Shivers horses identified by spatial transcriptomic and proteomic analyses
Background: Shivers in horses is characterized by abnormal hindlimb movement when walking backward and is proposed to be caused by a Purkinje cell (PC) axonopathy based on histopathology. Objectives: Define…

The Technical Feasibility of Digital Spatial Profiling in Immune/Inflammation Study of Thrombosis
Background: A comprehensive study of the distribution and role of immune/inflammatory cells in thrombosis is still lacking because traditional pathology techniques cannot accomplish the analysis of numerous protein and genetic…

Morphologic and molecular analysis of liver injury after SARS-CoV-2 vaccination reveals distinct characteristics
Background and Aims: Liver injury after COVID-19 vaccination is very rare and shows clinical and histomorphological similarities with autoimmune hepatitis (AIH). Little is known about the pathophysiology of COVID-19 vaccine-induced…

Digital spatial profiling of CD4+ T cells in classic Hodgkin lymphoma
Classic Hodgkin lymphoma (CHL) harbors a small number of Hodgkin-Reed-Sternberg (HRS) cells scattered among numerous lymphocytes. HRS cells are surrounded by distinct CD4+ T cells in a rosette-like manner. These…

The Vicious Cycle of Melanoma-Microglia Crosstalk: Inter-Melanoma Variations in the Brain-Metastasis-Promoting IL-6/JAK/STAT3 Signaling Pathway
Previous studies from our lab demonstrated that the crosstalk between brain-metastasizing melanoma cells and microglia, the macrophage-like cells of the central nervous system, fuels progression to metastasis. In the present…

Unraveling Heterogeneity in the Aging Hematopoietic Stem Cell Compartment: An Insight From Single-cell Approaches
Specific cell types and, therefore, organs respond differently during aging. This is also true for the hematopoietic system, where it has been demonstrated that hematopoietic stem cells alter a variety…
