Title:	Sensitizing cells for apoptosis by selectively blocking cytokines
Abstract:	The invention refers to the use of a cytokine antagonist which modulates the expression and/or the function of a cytokine, particularly a Th2 helper cell cytokine, in a cell and causes the down-regulation of anti-apoptotic proteins in said cell through the cytokine modulation for sensitizing cells for apoptosis. In particular, the cells that can be treated with the cytokine antagonists are drug-resistant cancer cells which fail to undergo apoptosis.
