Autophagy of pathogens alarms the immune system and participates in its effector functions


Romao, S; Münz, C (2011). Autophagy of pathogens alarms the immune system and participates in its effector functions. Swiss Medical Weekly, 141:w13198.

Abstract

Macroautophagy is a main catabolic pathway of eukaryotic cells, delivering cytoplasmic constituents for lysosomal degradation. Originally described as a starvation response, it has now been realised that macroautophagy supports many aspects of innate and adaptive immunity by facilitating innate pathogen detection and antigen presentation, as well as pathogen clearance and lymphocyte expansion. In the first half of this review, we summarise new insights into substrate selection and macroautophagic support of vesicular transport pathways, which underlie macroautophagic regulation of afferent and efferent immunity to pathogens, as outlined in the second half of the review. Applying this increased mechanistic understanding to infectious disease settings should allow us to identify further pathways for pathogen restriction, which can be explored for therapeutic manipulations of macro-autophagy.

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.
