abstract = {The blood stage malaria parasite, the merozoite, has a
small window of opportunity during which it must
successfully target and invade a human erythrocyte. The
process of invasion is nonetheless remarkably rapid. To
date, mechanistic models of invasion have focused
predominantly on the parasite actomyosin motor contribution
to the energetics of entry. Here, we have conducted a
numerical analysis using dimensions for an archetypal
merozoite to predict the respective contributions of the
host-parasite interactions to invasion, in particular the
role of membrane wrapping. Our theoretical modeling
demonstrates that erythrocyte membrane wrapping alone, as a
function of merozoite adhesive and shape properties, is
sufficient to entirely account for the first key step of the
invasion process, that of merozoite reorientation to its
apex and tight adhesive linkage between the two cells. Next,
parasite-induced reorganization of the erythrocyte
cytoskeleton and release of parasite-derived membrane can
also account for a considerable energetic portion of actual
invasion itself, through membrane wrapping. Thus, contrary
to the prevailing dogma, wrapping by the erythrocyte
combined with parasite-derived membrane release can markedly
reduce the expected contributions of the merozoite
actomyosin motor to invasion. We therefore propose that
invasion is a balance between parasite and host cell
contributions, evolved toward maximal efficient use of
biophysical forces between the two cells.},
