... Trx. As early as 1985, Yodoi and co-workers identified a new cytokine that they called ADF (ATL-derived factor), which augmented the expression of the IL-2 receptor [34] and was identical with a factor thought to be an isoform of IL-1 [35]. These were finally identified as Trx [36]. Subsequently var ...

Biochemical cascade

A biochemical cascade (or a signaling pathway) is a series of chemical reactions which are initiated by a stimulus (first messenger) acting on a receptor that is transduced to the cell interior through second messengers (which amplify the initial signal) and ultimately to effector molecules, resulting in a cell response to the initial stimulus. At each step of the signaling cascade, various controlling factors are involved to regulate cellular actions, responding effectively to cues about their changing internal and external environments.
