Role of gluons in a Netron star?

Wickipedia says: In physics, gluons are the elementary particles which are responsible for the strong nuclear force. They bind quarks together to form protons and neutrons as well as other hadrons; their electric charge is zero, their spin is 1 and they are generally assumed to have zero mass. Gluons are ultimately responsible for the stability of atomic nuclei.
So what is the role of gluons (if any) in a Neutron star (a quark star?)? To prevent gravitational collapse of the quarks, perhaps? Neil
