IMMNOHISTOLOGY OF THE SECONDARY LYMPHOID ORGANS AND IMMUNE CELL TRAFFICKING

by Kenjiro Matsuno, Department of Anatomy (Macro), Dokkyo Medical University


For an effective immune response, immune cell trafficking in the secondary lymphoid organs is crucial. However, the structures for the secondary lymphoid organs that guide this trafficking are still ill defined. This review describes general and specialized structures of rat secondary lymphoid organs, the LNs, spleen, and Peyer's patches. Trafficking patterns of T cell subsets and DC subsets in a steady state and pathological states are described with respect to microstructures and trafficking molecules.

For a convenience of attendants, I recently uploaded important figures and schemes used in my talk in this web site as below. These will be published soon in a review paper in a journal, Arch. Histol. Cytol. It would be a great pleasure of an anatomical immunologist if visitors could find interests in and become a little bit familiar with the morphology of the immune system.
