abstract = {Malaria parasites invade healthy red blood cells (RBCs)
during the blood stage of the disease. Even though parasites
initially adhere to RBCs with a random orientation, they
need to align their apex toward the membrane in order to
start the invasion process. Using hydrodynamic simulations
of a RBC and parasite, where both interact through discrete
stochastic bonds, we show that parasite alignment is
governed by the combination of RBC membrane deformability
and dynamics of adhesion bonds. The stochastic nature of
bond-based interactions facilitates a diffusive-like
re-orientation of the parasite at the RBC membrane, while
RBC deformation aids in the establishment of apex-membrane
contact through partial parasite wrapping by the membrane.
This bond-based model for parasite adhesion quantitatively
captures alignment times measured experimentally and
demonstrates that alignment times increase drastically with
increasing rigidity of the RBC membrane. Our results suggest
that the alignment process is mediated simply by passive
parasite adhesion.},
