Interleukin-21 (IL-21), a type I cytokine produced by activated T cells, has diverse effects on the immune system, but its ability to induce production of other cytokines is not well delineated. Furthermore, the signaling pathway underlying its action is poorly understood...
Recent publications revealed that bromelain exerts a marked effect on T-cell response by inhibiting T-cell signal transduction. These experimental studies may help to explain former clinical investigations showing that Phlogenzym (PHL), a preparation consisting of the proteases bromelain and trypsin and the antioxidant rutosid, ameliorate certain diseases with an underlying inflammatory process. In...
