WebDC biases their cytokine profile toward Th2, whereas presentation of GalCer by CD40-activated DC primes a Th1 response (10, 11). In addition, NKT cell activation can be induced by cytokines (independent from TCR/CD1d engagement). IL-18-, IL-18- plus IL-12-, and IL-12-induced pathways to fully activate NKT cells have been reported (12–14).

The pleiotropic functions of CD40 signaling in vivo have been previously reviewed. 3, 4 Briefly, CD40 expression on monocytes, and their progeny macrophages and DC, and B cells plays an important role in immune cell function. Monocytes are innate immune precursor cells with very high plasticity. WebCD40 is a cell-surface member of the TNF (tumor necrosis factor) receptor superfamily. Upon activation, CD40 can license dendritic cells to promote antitumor T cell activation and re-educate macrophages to destroy tumor stroma.
