The Multifaceted Role of Th17 Lymphocytes and Their Associated Cytokines in Cancer

Figure 2

Pro-versus anti-tumoral effects of Th17 lymphocytes and the cytokines they produce on cancer development. Th17 lymphocytes produce cytokines which may promote or impair tumor development. Depending on the microenvironment Th17 may differentiate into Th1 or hybrid lymphocytes capable of controlling tumor growth or into protumoral Treg. IDO: indoleamine 2,3-dioxygenase.
