Autophagy beyond intracellular MHC Class II antigen presentation


Münz, Christian (2016). Autophagy beyond intracellular MHC Class II antigen presentation. Trends in Immunology, 37(11):755-763.

Abstract

Autophagy is a group of cellular pathways that deliver cytoplasmic constituents for lysosomal degradation. The peptides generated from these pathways can be presented by MHC II molecules, making autophagy an important source of antigens for CD4+ T cells. In addition, modules of the molecular machinery of autophagy were found in recent years to also influence extracellular antigen processing for MHC Class I and Class II presentation, as well as regulation of MHC Class I surface expression. These studies paint a more complicated picture of how regulation of individual autophagy proteins influences adaptive immunity. The respective pathways, especially in regard to their net outcome for CD4+ helper and CD8+ cytotoxic T cell responses in vivo, will be discussed in this review.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
