<abstract>We consider the Cauchy problem of a parabolic-elliptic system in $\mathbf{R}^2$, which appears in various fields in physics and biology. Under a mild restriction on the initial data, we show the global existence of nonnegative solutions to the Cauchy problem for both the subcritical and the critical cases, that is, the total mass of the solution is less than or equal to $8\pi$.</abstract>
