To better understand autoimmune disorders, as well as responses to pathogens and vaccines, the Erikson lab investigates the interplay among different types of immune cells that result in immune system activation or suppression. Specifically, her lab has been studying the signals that guide immune cells down distinct developmental paths that result in short-term immunity or long-lasting responses and memory formation. These studies are highly relevant to autoimmune disease, infectious disease, and vaccine development.
The microscope in the image belonged to William E. Horner, M.D., a collaborator with Caspar Wistar, M.D., in the early 1800s.
Dr. Horner, a lecturer at the University of Pennsylvania, was a pioneer of the use of microscopes in anatomical and medical research. He authored Special Anatomy and Histology, a seminal text on the subject.
