Abstract
This paper deals with a parabolic-parabolic Keller-Segel system, modeling chemotaxis, with time dependent coefficients. We consider non-negative solutions of the system which blow up in finite time t* and an explicit lower bound for t* is derived under sufficient conditions on the coefficients and the spatial domain.
