Methods for modulating production of a T helper type 2 -associated cytokine, in particular interleukin-4, by modulating the activity of a transcription factor, in particular the proto-oncoprotein c-Maf, that regulates expression of the Th2-associated cytokine gene are disclosed. A wire way bar may facilitate connection and support for the devices, such as light sources and other systems. The electromechanical switch can include a distribution mechanism for replenishing a moisture inhibiting layer, such as an oleophobic material, on surface portions of conductive components within the switch.
