Plasma Cell Secrets
In vivo imaging supports new insights into the cells of the immune system
The Fooksman laboratory (Montefiore Einstein Department of Pathology, Albert Einstein College of Medicine, Montefiore Health System, Bronx, New York, USA) researches normal and malignant plasma cell physiology. These antibody-generating immune cells can survive for decades in the body. Because plasma cells are the architects of long-term immune response, it’s crucial to understand their life cycle and function. A better understanding of these cells can also support improved diagnosis and treatment of plasma cell malignancies such as multiple myeloma. In support of this research, David Fooksman and colleagues use in vivo imaging for cell visualization.

While obtaining degrees in biology from the University of Alberta and biochemistry from Penn State College of Medicine, I worked as a freelance science and medical writer. I was able to hone my skills in research, presentation and scientific writing by assembling grants and journal articles, speaking at international conferences, and consulting on topics ranging from medical education to comic book science. As much as I’ve enjoyed designing new bacteria and plausible superheroes, though, I’m more pleased than ever to be at Texere, using my writing and editing skills to create great content for a professional audience.
