Polyreactive–enriched, but not polyreactive-reduced, IgM from human serum binds to UV-induced apoptotic cells.
(a) Human T cells exposed to UV light were sorted into live (Annexin V−/7AAD−), early (Annexin V+/7AAD−) and late (Annexin V+/7AAD+) apoptotic populations. (b) The binding profile of polyreactive-enriched IgM and polyreactive-reduced IgM to apoptotic cells.
