title: Apicomplexan AMA1 in host cell invasion: a model at the junction?
abstract: Host cell invasion by the malaria parasite is a crucial step in its life cycle. In this issue of Cell Host & Microbe, Giovannini et al. (2011) raise questions about the validity of a widely accepted model of the tight junction, a ring-like structure through which the invading parasite passes.
