WebT Cell Activation via Concanavalin A Introduction T cells require external signals for differentiation and expansion from a quiescent state. Concanavalin A (con A) is an antigen-independent mitogen and can be used as an alternative T cell stimulus. WebNK cells are particularly sensitive to IL-12, IL-15, and IL-18 (Spits & Cupedo 2012). In contrast to T or B cells, NK cell activation is controlled by somatically encoded …
