    Analysis of matrisome expression patterns in murine and human dorsal root ganglia

    The extracellular matrix (ECM) is a dynamic structure of molecules that can be divided into six different categories and are collectively called the matrisome. The ECM plays pivotal roles in physiological processes in many tissues, including the nervous system. Intriguingly, alterations in ECM molecules/pathways are associated with painful human conditions and murine pain models. Nevertheless, mechanistic insight into the interplay of normal or defective ECM and pain is largely lacking. The goal of this study was to integrate bulk, single-cell, and spatial RNA sequencing (RNAseq) datasets to investigate the expression and cellular origin of matrisome genes in male and female murine and human dorsal root ganglia (DRG). Bulk RNAseq showed that about 65% of all matrisome genes were expressed in both murine and human DRG, with proportionally more core matrisome genes (glycoproteins, collagens, and proteoglycans) expressed compared to matrisome-associated genes (ECM-affiliated genes, ECM regulators, and secreted factors). Single cell RNAseq on male murine DRG revealed the cellular origin of matrisome expression. Core matrisome genes, especially collagens, were expressed by fibroblasts whereas matrisome-associated genes were primarily expressed by neurons. Cell–cell communication network analysis with CellChat software predicted an important role for collagen signaling pathways in connecting vascular cell types and nociceptors in murine tissue, which we confirmed by analysis of spatial transcriptomic data from human DRG. RNAscope in situ hybridization and immunohistochemistry demonstrated expression of collagens in fibroblasts surrounding nociceptors in male and female human DRG. Finally, comparing human neuropathic pain samples with non-pain samples also showed differential expression of matrisome genes produced by both fibroblasts and by nociceptors. This study supports the idea that the DRG matrisome may contribute to neuronal signaling in both mouse and human, and that dysregulation of matrisome genes is associated with neuropathic pain

    'Against the World': Michael Field, female marriage and the aura of amateurism'

    This article considers the case of Katherine Bradley and Edith Cooper, an aunt and niece who lived and wrote together as ‘Michael Field’ in the fin-de-siècle Aesthetic movement. Bradley’s bold statement that she and Cooper were ‘closer married’ than the Brownings forms the basis for a discussion of their partnership in terms of a ‘female marriage’, a union that is reflected, as I will argue, in the pages of their writings. However, Michael Field’s exclusively collaborative output, though extensive, was no guarantee for success. On the contrary, their case illustrates the notion, valid for most products of co-authorship, that the jointly written work is always surrounded by an aura of amateurism. Since collaboration defied the ingrained notion of the author as the solitary producer of his or her work, critics and readers have time and again attempted to ‘parse’ the collaboration by dissecting the co-authored work into its constituent halves, a treatment that the Fields too failed to escape

    'Sibling collaboration and literary after-life: the case of the Brontës'

    No full text
    This article argues that Charlotte Bronte effected a thorough mediation of Emily Bronte's authorial image after her death by becoming her sister's editor. For the 1850 edition of Wuthering Heights and Agnes Grey, Charlotte extensively edited Emily's poetry and wrote an influential 'Biographical Notice' and 'Preface'. She also composed new lines for some of the poems, establishing herself as a true co-author of her sister's work. Her purpose, as this article argues, was to soften the 'coarse', masculine image that the critics' reviews had attributed to the writer of Wuthering Heights. Thus, Charlotte created the image of a more innocent, female poet, in a deliberate (?) attempt to replace the existing view of Emily as a rough, unfeminine writer

    Afterlives of the Brontës: biography, fiction and literary criticism

    No full text
    Afterlives of the Brontës revisits the Brontë myth by uncovering new details about the Brontës’ representations in biographies, art and criticism: how are the Brontës represented at different times, in different contexts and different media? It furthermore inquires into various perspectives on authorship: what do the Brontës’ afterlives tell us about the figure of the author, traditionally portrayed as a single entity or literary genius? Finally, it reflects on the theory and practice of afterlife study: how does one negotiate the tension between fact and fiction, author and text

Cell-cell communication network analysis with CellChat software predicted an important role for collagen signaling pathways in connecting vascular cell types and nociceptors in murine tissue, which we confirmed by analysis of spatial transcriptomic data from human DRG. RNAscope in situ hybridization and immunohistochemistry demonstrated expression of collagens in fibroblasts surrounding nociceptors in male and female human DRG. Finally, comparing human neuropathic pain samples with non-pain samples also showed differential expression of matrisome genes produced by both fibroblasts and by nociceptors. This study supports the idea that the DRG matrisome may contribute to neuronal signaling in both mouse and human, and that dysregulation of matrisome genes is associated with neuropathic pain
