We describe the similarities and the specificities of the behaviour of individual soft particles, 10 namely, drops, lipid vesicles and red blood cells subjected to a shear flow. We highlight that their motion depends in a non trivial way on the particle mechanical properties. We detail the effect of the presence of a wall with or without wall-particle attractive interaction from a biological perspective.
