Query: $N^*$ states with hidden charm and a three-body nature   In this work we study the formation of $N^*$'s as a consequence of the
dynamics involved in the $ND\bar D^*-N\bar D D^*$ system when the $D\bar
D^*-\bar D D^*$ subsystem generates $X(3872)$ in isospin 0 and $Z_c(3900)$ in
isospin 1. States with isospin $I=1/2$ and mass in the energy region
$4400-4600$ MeV are obtained with spin-parity $J^P=1/2^+$ and $3/2^+$,
predicting in this way the existence of $N^*$ resonances with hidden charm and
a three-body nature.
