In situ imaging of bacterial membrane projections and associated protein complexes using electron cryo-tomography

Abstract: The ability to produce membrane projections in the form of tubular membrane extensions (MEs) and membrane vesicles (MVs) is a widespread phenomenon among bacteria. Despite this, our knowledge of the ultrastructure of these extensions and their associated protein complexes remains limited. Here, we surveyed the ultrastructure and formation of MEs and MVs, and their associated protein complexes, in tens of thousands of electron cryo-tomograms of ∼ 90 bacterial species that we have collected for various projects over the past 15 years (Jensen lab database), in addition to data generated in the Briegel lab. We identified MEs and MVs in 13 species and classified several major ultrastructures: 1) tubes with a uniform diameter (with or without an internal scaffold), 2) tubes with irregular diameter, 3) tubes with a vesicular dilation at their tip, 4) pearling tubes, 5) connected chains of vesicles (with or without neck-like connectors), 6) budding vesicles and nanopods. We also identified several protein complexes associated with these MEs and MVs which were distributed either randomly or exclusively at the tip. These complexes include a secretin-like structure and a novel crown-shaped structure observed primarily in vesicles from lysed cells. In total, this work helps to characterize the diversity of bacterial membrane projections and lays the groundwork for future research in this field.

A Genealogy of Neocolonial Social Comportment

Abstract: This chapter explores the foundations of neocolonial power and its associated feminist counterpart. Neocolonial feminism refers to a curated standard of public “secular” and “professional” comportment that is held up as an ideal for women of color whose cultures or features locate them as culturally or behaviorally subordinate to “Western” feminist ideals. Liberal feminist standards, as expressed through Martha Nussbaum, are one example of neocolonial feminist expectations. The neocolonial gaze is one by which Muslim women—among other women of color—are taken up and reproduced as legible diasporic children who must be taught to behave. This chapter also explores the intersections of neocolonial and neoliberal feminism as it affects Muslim women of color.

Introduction: Literary Cultures and Twentieth-Century Childhoods

Abstract: This collection offers a range of innovative methodological and disciplinary approaches to the intersection of literary cultures with children and childhoods across the twentieth century. The volume engages with two crucial acts of re-centering: not only focusing on the multiplicity of childhoods, but also centering the agency of children, including foregrounding the representation of child voices and subjectivities within texts. Chapters explore such themes as challenges to received notions of childhood and the role of child-oriented texts in larger cultural and political projects. Another intent of the volume is to explore literary culture not only as a body of materials produced by adults for consumption by children but also as co-created by young people through their actions as speakers, artists, readers, and writers.
