Fundamental properties of the dark and the luminous matter from Low
  Surface Brightness discs
  Dark matter (DM) is one of the biggest mystery in the Universe. In this
review, after a brief discussion of the DM evidences and the main proposed
candidates and scenarios for the DM phenomenon, we focus on recent results on
rotating disc galaxies giving a special attention to the Low Surface Brightness
(LSB) galaxies. The main observational properties related to the baryonic
matter in LSBs, investigated over the last decades, are briefly recalled. Next,
the LSBs are analysed by means of the mass modelling of their rotation curves
both individually and stacked. The latter analysis, via the Universal Rotation
Curve (URC) method, results really powerful in giving a global/universal
description of the disc galaxies properties. We show the presence in LSBs of
scaling relations between the galactic structural properties and we compare
them with those of galaxies of different morphologies. The findings confirm,
for all disc systems, a strong entanglement between the luminous matter (LM)
and the DM. Moreover, we report how in LSBs the tight relationship between
their radial gravitational acceleration $g$ and their baryonic component $g_b$
results to also depend on the galactic radius at which the former have been
measured. Finally, LSB galaxies strongly challenge the $\Lambda$CDM scenario
with the relative collisionless dark particle and, alongside with the
non-detection of the latter, contribute to guide us towards a new scenario for
the DM phenomenon.
