Welcome — Lamason Lab

Rickettsia (green) infected cells - nuclei (purple) and mitochondria (gold)

Rickettsia (red) moving through host cells with long actin tails (green)

Motile Listeria (blue bacteria, red actin tails) spreading through a host monolayer with long membrane protrusions marked in green (plasma membrane)

Infectious focus of spreading bacteria (red, plasma membrane; green, bacteria; blue, nuclei)

mechanisms of HOst-Pathogen Interactions

In the Lamason lab, we investigate how intracellular bacterial pathogens such as Rickettsia parkeri and Listeria monocytogenes hijack host cell processes to promote infection. We use cellular, molecular, genetic, biochemical, and biophysical approaches to elucidate the mechanisms of host-pathogen interactions in order to reveal key insights into pathogenesis and host cell biology.
