  1. There is no single biomarker with absolute specificity for cellular or immune cell senescence [188] and a multi-marker approach to detection and identification, in non-MS and MS-based studies, has been applied in the compilation of Tables 1 and 2.  Furthermore, the biomarkers, some of which are, to date, not verified (NV) or verified (V) and common to pISC and arISC (*) following exposure to environmental stressors or during MS, and confirmed in immune cell populations as previously detailed [309,310,311].  Verification of MS-associated or environmental risk factor-related hallmarks of immune cell-related senescence indicates a close inter-relationship.  There is also an inter-connection provided by the comprehensive picture of a relationship with pISC and arISC despite conjecture over biomarker expression in MS (†) [312,313,314,315,316,317]
