title: Recognition of lipid antigens by T cells.
abstract: Recent studies have shown that the recognition of lipid antigens by the immune system is important for defence against infection and other diseases, and that lipid-specific responses occur at higher frequencies than previously suspected. Thanks to several recent advances in this field, we now have a better appreciation of the molecular and cellular requirements of T-cell stimulation by lipids. These findings have raised new questions about the mechanisms of lipid presentation, the priming and clonal expansion of lipid-specific T cells, and their differentiation into memory cells. A greater understanding of lipid-specific T cells and the molecular mechanisms of lipid immunogenicity should facilitate the development of lipid-based vaccines.
