Figure 1

A cardiovascular diabetologic approach to the 29 known interleukins. The noxious interleukins ("bad") are depicted as red triangles, the protective ("good") as green circles, and the aloof as yellow squares. Interleukin-3 is depicted as a half red-half green square due to its ambiguity: albeit "good" in terms of glucose metabolism, it was not clustered into this group due to its effects on the heart (see text: Curtail of the scope).
