Our knowledge and understanding of the various forms of lymphocytes continue to expand. Our initial discussion this week will be on the various forms of B and T cells -- each of us should take one class of lymphocytes and explain it's role in the adaptive immune process. As you comment on other students' postings be sure to add additional insight into the mechanisms of the subclass of cell and its interactions with both components of the innate and other aspects of the adaptive immune system.
