| The Nature Publishing Group (NPG) has published many landmark papers on antigen processing. These have provided molecular insights into how peptides are selected and presented to immune cells. Here, we have selected a sampling of recent NPG papers describing current research on epitope generation and presentation of nonpeptide antigenic ligands to T lymphocytes. Clicking on any of these links will take you to the online articles (which are available free-of-charge until 31 July 2004). |
