""" When a tumor cell rapidly grows it uses up all the nutrients that the blood supply can provide. The cells get stressed. They start to consume unwanted proteins and give off proteins in the process. Moditope converts these proteins and when they do, the immune system recognises the tumor and triggers a powerful immune response. Moditope 1 and 2 are just two different ways in which these proteins and converted.""""
Sorry mate this is just not correct ..
Cell under stress consumes unwanted proteins within its cell "recycled " this is autophagy ...
under this condition coupled with an external cytokine induced by inflammation the cell identifies itself by a protein on it outside surface
Its not "giving off proteins
so this is a citrullinated cell displaying an epitope as an identification ..
Modi2 is also an Autophagy event .. Homocitrulline
Autophagy is a homeostatic and physiological process that promotes the turnover of proteins and organelles damaged in conditions of cellular stress. We previously demonstrated that autophagy represents a key processing event creating a substrate for autoreactivity, which is involved in post-translational changes and generation of citrullinated peptides, recognized by the immune system in RA. In this study, we analysed whether autophagy is involved in other post-translational changes that can generate autoantigens, focusing on carbamylation processes. Carbamylation is a nonenzymatic post-translational modification, in which homocitrulline is generated by the reaction of cyanate with the primary amine of lysine residues; carbamylated peptides may accumulate during inflammation conditions.
so Moditope is ......... citrullinated tumour-associated peptide or a Homocitrulline tumour-associated peptide
so moditope does not engage "inside the cell"
hope that explains it better
