ABSTRACT Katrina Velle is a cell biologist who uses microscopy to study amoebae. In this mSphere of Influence article, she reflects on how a classic paper on Listeria by Tilney and Portnoy made an impact on her by highlighting how much we can learn f

Enteropathogenic and enterohemorrhagic E. coli (EPEC and EHEC) are closely related extracellular pathogens that reorganize host cell actin into "pedestals" beneath the tightly adherent bacteria. This pedestal-forming activity is both a critical step

Controlling intracellular osmolarity is essential to all cellular life. Cells that live in hypo-osmotic environments like freshwater must constantly battle water influx to avoid swelling until they burst. Many eukaryotic cells use contractile vacuole

Enteropathogenic and enterohemorrhagic Escherichia coli (EPEC and EHEC) are closely-related pathogens that attach tightly to intestinal epithelial cells, efface microvilli, and promote cytoskeletal rearrangements into protrusions called actin pedesta

Amoeboid cell types are fundamental to animal biology and broadly distributed across animal diversity, but their evolutionary origin is unclear. The closest living relatives of animals, the choanoflagellates, display a polarized cell architecture (wi

The actin cytoskeleton governs a vast array of core eukaryotic phenotypes that include cell movement, endocytosis, vesicular trafficking, and cytokinesis. Although the basic principle underlying these processes is strikingly simple - actin monomers p

Correlating the location of subcellular structures with dynamic cellular behaviors is difficult when working with organisms that lack the molecular genetic tools needed for expressing fluorescent protein fusions. Here, we describe a protocol for fixi

[Background] The opportunistic pathogen Naegleria fowleri establishes infection in the human brain, killing almost invariably within 2 weeks. The amoeba performs piece-meal ingestion, or trogocytosis, of brain material causing direct tissue damage an

Naegleria diverged from the “yeast-to-human” lineage >1 billion years ago. Velle and Fritz-Laylin found that Naegleria, which lacks interphase microtubules, has a robust actin cytoskeletal repertoire and uses conserved, Arp2/3–derived actin net
