- Introduction
- T cell activation
- Dendritic cells (DC)
- Immune activation (1)
- Pattern recognition
- Bug recognition by Toll-like receptors in mammals
- PRRs: coupling innate and adaptive immunity
- Immune activation (2)
- Viruses induce type I/III interferons
- Induction of type I interferons is pattern recognition
- Pattern recognition of viruses
- IFN-alpha production and cytoplasmic dsRNA
- IFN-alpha/beta induction by cytoplasmic dsRNA
- Influenza virus
- Influenza NS1 protein blocks IFN-a/b production
- Cytoplasmic recognition of flu
- Induction of IFN-a does not correlate with dsRNA
- RIG-I mediated flu sensing
- Transfection with flu vRNA is sufficient to elicit IFN
- RIG-I binds directly to flu vRNA
- RIG-I mediated sensing of flu genomes
- Induction of type I/III interferons
- Recognition is specific to vRNA
- CIP abrogates the ability of flu vRNA to induce IFN
- Conclusions (1)
- 5' PPP RNA binds to the CTD of RIG-I
- Why RIG-I doesn't mediate responses to EMCV
- What about self ssRNA?
- The actual RIG-I agonist during virus infection
- IFN-a/b induction by viruses - Cytosolic pathways
- Mouse DC subsets
- pDC make lots of IFN-a in response to wild type flu
- Conclusions (2)
- pDC responses to flu require TLR7
- Endosomal recognition of viruses
- Virus recognition pathways
- TLR7 recognises poly U clusters
- TLR7 recognises self mRNA
- Conclusions (3)
- What about apoptotic cells? (1)
- Spleen DC subsets
- Scavenging by CD8-alpha positive DC
- What about apoptotic cells? (2)
- CD8a+ DC do not express TLR7 but express TLR3
- DC "decode" signs of infection within dying cells
- Detecting virally-infected cells
- Replication of some viruses generates dsRNA
- DC activation by virally-infected cells
- Virus-infected cells induce CTL responses
- CTL priming after TLR3-mediated dsRNA sensing
