- Summary
Topics Covered
- Understanding how receptors involved in the detection of infection (TLRs and NLRs) and inflammation (TNFRs) mediated their biological effects
- The activation of innate immune responses depends on recognition of infectious organisms (bacteria, fungi, viruses, etc.) by specialized pattern recognition receptors that include the large families of membrane-associated TLRs and cytosolic NLRs
- Signaling mechanisms used by TLRs and NLRs, as well as by TNFRs that respond to pro-inflammatory cytokines
- Their biological effects include the production of cytokines, chemokines, anti-microbial peptides and enzymes that generate inflammatory mediators and reactive oxygen
