... [39], one interpretation of the results obtained by Huang et al. [41] is that intrinsic defense mechanisms in adipose tissue limit adipogene- sis by reducing the expression of ApoE in the fed state. Certainly, ... atheroprotective property of ApoE may be counter-acted by the enhanced depo- sition of dietary lipids to adipose tissue (Fig. 2), which may be the result, at least i...
