To celebrate BSI Congress 2017, this virtual issue combines articles from both the BSI’s journals, Immunology and Clinical & Experimental Immunology, with a focus on Inflammasomes and Inflammatory Disease, a topic inspired by the keynote session to be presented by one of the most eminent scientists working in the field of innate immunity, Luke O'Neill FRS.
Much of the activity of the immune system is influenced by the signalling pathways that stem from pattern recognition receptors (PRRs). This diverse collection of protein receptors recognises specific danger or pathogen associated molecular patterns (DAMPS/ PAMPS) and consequently initiates signalling cascades that regulate both the innate and the adaptive arms of the immune system. Feedback loops and molecular associations between different families of PRR enable appropriate immune responses to be matched to the vast diversity of pathogens, and host-derived threats or indeed, commensals. An example of such assemblies are the inflammasomes, molecular machines whose activation induces an inflammatory response, primarily through the production of pro-inflammatory cytokines such as interleukin-1β (IL-1β) and interleukin-18 (IL-18).
As cellular alarm systems, PRRs are invaluable in the maintenance of immune homeostasis. However, due to the extreme outcomes of their activation, strict regulation is required and dysregulated control can lead to serious damage.
This collection of articles features some of the key reviews and primary research papers examining PRRs, and inflammasomes, and how their downstream products may play a role in inflammatory disease. With improved understanding of the underlying molecular mechanisms, possible new therapies to treat dysregulated immune responses come ever closer.
All the articles in this collection have been published in issues of the journals from 2015 to 2017, and are FREE to view and download.
