  In this work, we prove the well-posedness and propagation of chaos for a
stochastic particle system in mean-field interaction under the assumption that
the interacting kernel belongs to a suitable $L_t^q-L_x^p$ space. Contrary to
the large deviation principle approach recently proposed in [2], the main
ingredient of the proof here are the \textit{Partial Girsanov transformations}
introduced in [3] and developed in a general setting in this work.
