Murine models of disease are vital to the understanding of pathogenesis and the development of novel therapeutics. We have previously established interleukin (IL)-15 transgenic (tg) mice that demonstrate rapid proliferation of natural killer (NK) and T cells, followed by spontaneous transformation to lethal leukemia. Herein, we have characterized this model, which has many features in common with the aggressive variants of NK and T large granular lymphocyte leukemia (LGLL) in humans. The LGLL blasts are cytolytic and produce IFN-gammaex vivo. Cytogenetic analysis revealed trisomy of chromosome 17 and/or 15. This model should provide opportunities to develop effective standard therapies for this fatal disease.

Direct Immunofluorescence in Dermatomyositis and Lupus Erythematosus: Cross-Sectional Diagnostic Accuracy and Correlation With Serologies and Other Features of Systemic Disease.

This is a retrospective cross-sectional diagnostic test accuracy study of direct immunofluorescence (DIF) performed on a group of potential lupus erythematosus (LE)/dermatomyositis (DM) skin biopsies from 2015 to 2020 at a large, academic medical center. For purposes of this study, which was focused primarily on detection of LE/DM-related interface dermatitis, DIF was considered positive for a LE/DM pattern if it showed granular deposition of immunoglobulin G, with or without C3, at the basement membrane zone on the final pathology report. Blinded clinicopathologic correlation was the reference standard.

Towards a 'people and nature' paradigm for biodiversity and infectious disease.

Zoonotic and vector-borne infectious diseases are among the most direct human health consequences of biodiversity change. The COVID-19 pandemic increased health policymakers' attention on the links between ecological degradation and disease, and sparked discussions around nature-based interventions to mitigate zoonotic emergence and epidemics. Yet, although disease ecology provides an increasingly granular knowledge of wildlife disease in changing ecosystems, we still have a poor understanding of the net consequences for human disease.

For over a century researchers have marveled at the square-shaped toe tips of several species of climbing salamanders (genus Aneides), speculating about the function of large blood sinuses therein. Wandering salamanders (Aneides vagrans) have been reported to exhibit exquisite locomotor control while climbing, jumping, and gliding high (88 m) within the redwood canopy; however, a detailed investigation of their digital vascular system has yet to be conducted. Here, we describe the vascular and osteological structure of, and blood circulation through, the distal regions of the toes of A.
