Characterisation of CD8 monoclonal antibody-induced protection from diabetes in NOD mice

NOD mice can be protected from transferred diabetes for long periods by short-term treatment with CD8 mabs. This protection has previously been shown to be thymus-dependent as thymectomised mice do not show the long-term protection observed in intact mice. In this study we show that the thymus is required only during antibody treatment as its removal thereafter does not affect protection. Recent thymic emigrants (RTEs) are not necessary for long-term tolerance induction and irradiation plays no part as anti-CD8 treatment cannot protect NOD.scid recipients from diabetes development. IL-10 is also shown to play an important role in the anti-CD8 induced protection in intact mice as it is reversed by IL-10R blockade.
