The identification of the Major Histocompatibility Complex (MHC) class I and class II molecules as presenting elements for the recognition of peptide antigens by T cells is one of the most fundamental principles of the adaptive immune response. While this mechanism clearly lies at the heart of most adaptive immunity, it has also become clear in recent years that specific T cell recognition of other types of antigens through mechanisms that are not dependent on the MHC also exist. One of the best-characterized of the MHC-unrestricted pathways for specific T cell responses involves the CD1 system, a family of nonpolymorphic antigen presenting molecules that controls the recognition of lipid and glycolipid antigens by T cells. In the current review, we provide a general overview of the CD1 system with an emphasis on its potential role in adaptive immunity to microbial infection.

Carbohydrate-Based Targets and Vehicles for Cancer and Infectious Diseases Vaccines

Vasso Apostolopoulos, Magdalena Plebanski and Ian McKenzie

The last decade has seen carbohydrates used not only as targets for effective vaccines against bacteria, but also developed as adjuvants and vaccine carriers for protein antigens for immunotherapy. ...

Antibody Responses to Polysaccharides

Carola G. Vinuesa and Ian C.M. MacLennan

The polysaccharide capsules of Haemophilus influenzae b, pneumococci and meningococci protect these bacteria from innate immune mechanisms. Consequently, antibody responses to these encapsulated...
