Subject: Is the Pauli Exclusion Principle

In a neutron star, neutrons are "held up" against gravity by the Pauli 
Exclusion Principle. Similarly for electrons around an atom.  Neutrinos 
also must experience this phenomenon, being Fermions.  I'm aware that this 
is a result of the exchange correlation, because when you swap the 
positions of the particles, the wavefunction is inverted, so the chance of 
the particles occupying the same state must be zero.  However, is there 
any sense in which this apparent force is mediated by a boson, as with 
other forces between Fermions, such as the electroweak, strong and 
gravitational forces?
