- This article examines the similarities and differences in the education and training of gerontologists and others who work with older people in Sweden and the United States. It outlines the aging trends in both countries and assesses the level of training for those who provide care in a variety of fields. Both countries are aging, but the programs for gerontological training are quite different in the two countries, reflecting underlying cultural values. Sweden’s education is generally more oriented toward the integration of some aging education in more disciplinary fields, such as nursing and social work and thus could benefit from more specialized, aging-specific courses. The United States is highly specialized, with multiple programs in various subfields of aging (e.g., geropsychology; aging services administration) and could benefit from integrating more aging knowledge into courses in other disciplines. The authors challenge professionals to consider if there is a basic but global curriculum and/or set of competencies in gerontology that could be agreed upon. As an increasingly global village, the ability to share and learn is more easily achievable. Sweden and the United States have much to learn from each other in terms of appropriately educating and training those who support our older people.

- The α-pore-forming toxins (α-PFTs) from pathogenic bacteria damage host cell membranes by pore formation. We demonstrate a remarkable, hitherto unknown mechanism by an α-PFT protein from Vibrio cholerae. As part of the MakA/B/E tripartite toxin, MakA is involved in membrane pore formation similar to other α-PFTs. In contrast, MakA in isolation induces tube-like structures in acidic endosomal compartments of epithelial cells in vitro. The present study unravels the dynamics of tubular growth, which occurs in a pH-, lipid-, and concentration-dependent manner. Within acidified organelle lumens or when incubated with cells in acidic media, MakA forms oligomers and remodels membranes into high-curvature tubes leading to loss of membrane integrity. A 3.7 Å cryo-electron microscopy structure of MakA filaments reveals a unique protein-lipid superstructure. MakA forms a pinecone-like spiral with a central cavity and a thin annular lipid bilayer embedded between the MakA transmembrane helices in its active α-PFT conformation. Our study provides insights into a novel tubulation mechanism of an α-PFT protein and a new mode of action by a secreted bacterial toxin.
