We discuss the properties of particles and fields in a multi-dimensional space-time, where the geometrization of gauge interactions can be performed. For instance, in a 5-dimensional Kaluza-Klein manifold, we argue that the motion of charged spinning bodies is obtained in a Papapetrou-like formulation. As far as spinors are concerned, we outline how the gauge coupling can be recognized by using a proper dependence on extra-coordinates and by using the dimensional reduction procedure. Kaluza-Klein theories.
