Abstract
The rolling is an important kind of cell adhesion,
especially in the case of the immune mechanism, due to the leukocyte action,
which is strongly influenced by molecular affinity [1]. Our purpose, in this paper, is the presentation of a 3D theorical model
which describes the behaviour of the contact interface cell-wall during the
rolling and the cell deformation. The first point concerns the modelling of
the contact interface, which is assimilated to a circular plate, linked to
the wall (e.g vein) by elastic springs. The second point concerns the
modelling of the active deformation due to the change of the cytoskeleton
structure during the cell motility.
