Researchers in the laboratory of Andrew J. Caton, Ph.D., aim to illuminate the mechanisms that govern the immune system’s ability to react against viruses and other pathogens, and to prevent responses against “self”--the human body’s own tissues. The laboratory strives to define the mechanisms by which T cells and B cells are regulated, and to understand how these processes fail and/or can be manipulated in infections, and in diseases such as rheumatoid arthritis, lupus, and cancer.
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.
