Alum increases antigen uptake, reduces antigen degradation and sustains antigen presentation by DCs in vitro

► The EαGFP/YAe system can be used to study the impact of alum on antigen uptake and presentation by DCs. ► Alum acts as an antigen delivery system. ► Alum slows down protein degradation in DCs. ► Alum eventually enhances magnitude and duration of expression of peptide/MHC complexes on the DC surface.
