Recently muscarinic receptors, particularly [M.sub.1] and [M.sub.3] receptors, were shown to be linked to activation of [G.sub.12/13]-type G proteins, which leads to activation of small GTP-binding proteins Rho through activation of RhoGEF (RhoGTPase nucleotide exchange factor) (see a review ref.

In large part, the anti-inflammatory actions of statins result from the depletion of two biologically important cholesterol pathway intermediates, farnesyl pyrophosphate (FPP) and geranylgeranyl pyrophosphate (GGPP), which are required for posttranslational modification of small GTP-binding proteins (small GTPases) such as Ras (FPP) or Rac and Rho (GGPP) (Figure 3).

Despite the dramatic changes induced by EPEC in the cytoskeleton, there appears to be little involvement of the Rho family of small GTP-binding proteins normally involved in cytoskeletal rearrangements (29).
