  We present the broad-band soft and hard X-ray spectral analysis of 8 Narrow
Line Seyfert 1 galaxies extracted from the IBISCO Sample. The study also
focuses on the properties of the NLS1 in our sample in relation to those of the
IBISCO parent Seyfert population. The IBISCO sample comprises 57 AGN selected
from the INTEGRAL IBIS AGN catalogue (in the 20-100 keV band), with z$<$0.05
and covering a wide range of luminosities, BH masses and absorption. All AGN
have also measurements of the molecular gas (H$_2$) content of their host
galaxies, through the detection of CO emission lines. The main goals of this
analysis are to accurately determine the X-ray continuum emission, investigate
the presence of absorption features around 7 keV (indicative of the presence of
outflows) and measure the bolometric luminosity in order to study the accretion
parameters of the eight IBISCO NLS1, and study the accretion mechanisms and
investigate the feeding and feedback cycle in these peculiar AGN. Preliminary
results show that NLS1 tend to have higher Eddington ratios and larger
molecular gas fractions than their parent Seyfert population in the IBISCO
sample. Nuclear (AGN) vs. host galaxy properties scaling relations of NLS1 in
relation to the parent Seyfert population are also explored.
