These cells are often located in para-cortical areas of lymph nodes.
These cells are eliminated through activation-induced cell death. A subtype of these cells differentiate in the presence of IL-12 from macrophages. These cells express CD28, which binds to B7 as part of their activation. CD3 is a signal-transduction molecule for their receptors, which recognize cell-bound peptides. These cells are often located in para-cortical areas of lymph nodes. MHC class I molecules interact with their cytotoxic type, and MHC class II molecules interact with their helper type. For 10 points, name these lymphocytes that develop in the thymus.
