The interactions of $\bar{ D}\Sigma_{ c}$-$\bar D\Lambda_c$, $\bar{ D}^{ *}\Sigma_{ c}$-$\bar D^*\Lambda_c$, and related strangeness channels, are studied within the framework of the coupled channel unitary approach with the local hidden gauge formalism. A series of meson-baryon dynamically generated relatively narrow $N^*$ and $\Lambda^*$ resonances are predicted around 4.3 GeV in the hidden charm sector. We make estimates of production cross sections of these predicted resonances in $\bar{ p} p $ collisions for PANDA at the forthcoming FAIR facility.
