Christine Suetterlin, Ph.D.

also spelled Sutterlin or Sütterlin

A main interest of the Suetterlin lab is the biology of Chlamydia infection. The human pathogen Chlamydia trachomatis is the most common cause of bacterial sexually transmitted disease, with more than 1.8 million new cases reported annually in the U.S. (CDC, 2021). However, Chlamydia is not only a wide-spread and successful human pathogen, but it is also an exciting bacterium with interesting biology. Its unique biphasic developmental cycle takes places within a membrane bound compartment, called the inclusion and involves conversion between an infectious and a non-infectious form.

I am using my training in cell biology to understand 1) how Chlamydia, from within the inclusion, manipulates host cell organelles, such as ER, Golgi and centrosome, 2) how the host cell alters the infection and 3) how the unique chlamydial developmental cycle is regulated.

We use tissue-culture infection models and cell biological, biochemical and microscopy-based approaches to address these exciting aspects of Chlamydia biology. This work is done in close collaboration with Dr. Ming Tan (UCI’s School of Medicine) and is supported by grants from NIH.

A second area of research interest is the organization and function of the centrosome, the major microtubule organizing center of the cell. Here, we are pursuing three exciting projects: 1) to understand if the physical proximity between the Golgi and the centrosome in mammalian cells, is important for the organization and function of these organelles, 2) to examine the mechanism of centrosome assembly and 3) to determine the role of the daughter centriole.
