Abstract

Catalytic Abs (catAbs) are multivalent im-munoglobulins (Igs) with a capacity to hy-drolyze the antigenic (Ag) substrate. In this sense, proteolytic Abs (Ab-proteases) repre-sent Abs to provide proteolytic effects. Abs against myelin basic protein/ MBP with pro-teolytic activity exhibiting sequence-specific cleavage of MBP are of great value to moni-tor demyelination whilst in MS. The activity of Ab-proteases was first registered at the subclinical stages 1-2 years prior to the clin-ical illness. And the activity of the Ab-proteases revealed significant correlation with scales of demyelination and the disabil-ity of the patients as well. So, the activity of Ab-proteases and its dynamics tested would confirm a high subclinical and predictive (translational) value of the tools as applicable for personalized monitoring protocols. Of tremendous value are Ab-proteases directly affecting remodeling of tissues with multilevel architectonics (for instance, mye-lin). By changing sequence specificity one may reach reduction of a density of the neg-ative proteolytic effects within the myelin sheath and thus minimizing scales of demye-lination. Ab-proteases can be programmed and re-programmed to suit the needs of the body metabolism or could be designed for the development of new catalysts with no natural counterparts. Further studies are needed to secure artificial or edited Ab-proteases as translational tools of the newest generation to diagnose, to monitor, to con-trol and to treat and rehabilitate MS patients at clinical stages and to prevent the disorder at subclinical stages in persons-at-risks to secure the efficacy of regenerative manipula-tions.
