MIT Researchers Pioneer CRISPR Techniques to Uncover Pathogen-Host Interactions in R. parkeri and Listeria
  • MIT researchers led by Rebecca Lamason have developed novel techniques to study R. parkeri and Listeria monocytogenes, including the first CRISPR-based gene targeting in R. parkeri and methods to label bacterial proteins secreted into host cells for clearer functional studies.

  • Lamason’s lab aims to move beyond easy-to-study models like E. coli and S. aureus to examine harder-to-study pathogens, with the goal of uncovering how diverse pathogens interact with host cells.

  • The lab’s work on pathogens such as Rickettsia parkeri and Listeria monocytogenes seeks to reveal how infections hijack host cell machinery and to illuminate fundamental host cell functions.

  • Outside the lab, Lamason plays in a women’s hockey league in Boston to decompress from research pressures and maintain balance.

  • Her participation in women’s hockey in Boston serves as a routine to manage academic stress and keep life in balance with her scientific career.

  • Lamason’s career path—from early biology interest through community college, Millersville University, Johns Hopkins, UC Berkeley, and MIT—reflects a sustained drive to understand how different biological systems interact.

  • Her background includes studying cell biology at Millersville University, exploring zebrafish cancer genetics before graduate school, and conducting postdoctoral work at UC Berkeley on host-pathogen interactions, shaping an interdisciplinary approach.

  • MIT’s collaborative culture and access to cross-lab expertise have been central to Lamason’s ability to tackle new techniques and pursue organelle-focused questions.

  • The lab emphasizes collaboration and leveraging MIT’s cross-lab resources to overcome technical challenges and pursue riskier, exploratory questions.

  • Recent work reveals a unique tight interaction between Rickettsia parkeri and the endoplasmic reticulum, a finding not observed with other microbes and hinting at novel infection mechanisms.

  • Notably, R. parkeri forms tight connections with the endoplasmic reticulum, indicating distinctive host-pathogen interactions that are still under investigation.
