  The KLOE-2 experiment at the INFN Laboratori Nazionali di Frascati (LNF)
completed its data-taking at the $e^+ e^-$ DA$\Phi$NE collider, which
implements an innovative collision scheme based on a crab-waist configuration,
and achieved the integrated luminosity of more than 5 fb$^-1$. KLOE-2
represents the continuation of KLOE with an upgraded detector and an extended
physics program which includes, among the main topics, neutral kaon
interferometry and test of discrete symmetries . Entangled neutral kaon pairs
produced at DA$\Phi$NE are a unique tool to test discrete symmetries and
quantum coherence at the utmost sensitivity, strongly motivating the
experimental searches of possible CPT violating effects, which would constitute
an unambiguous signal of New Physics. The status of the test of Time reversal
and CPT simmetry in $\phi \to \mbox{K}_S \mbox{K}_L \to \pi\nu,3\pi^0,(2\pi)$
decays with KLOE and KLOE-2 data will be discussed.
