Figure 1: Sarcoid anergy, tuberculin test, and the status of cell-mediated immunity (CMI). (a) Sarcoid anergy is mediated through PGE2 and deficit of IL-2; it is reversed with Indomethacin, steroids, and exogenous IL-2 leading to delayed type (IV) hypersensitivity (DTH); (b) it shows the presence and size of the induration which in turn reflects (c) the status of CMI against the mycobacterial antigens
