One of the first cells to be recruited to the site of infection; releases granules to kill the pathogen
What are neutrophils
Intracellular sensors for microbial products that contain a nucleotide binding oligomerization domain and an LRR domain
What are NOD-like Receptors
This complement protein exists as a zymogen until spontaneously activated to initiate complexes on the surface of the cell
What is C3?
The first barrier of defense against infection
What are the skin and mucosae
Sense cytoplasmic viral RNAs and induce production of type I interferons
What are RIG-I-like receptors
The composition of the alternative C3 convertase
What is C3bBb?
Bone marrow and Thymus
This molecule is an adaptor protein for TLR4 signaling; linking a key kinase to an intracellular signaling domain
What is MyD88
A protein which when released during the acute phase, binds carbohydrates on the surface of the pathogen to initiate complement signaling
What is a (mannose-binding) lectin?
These cells mature to produce helper cells and cytotoxic cells
What are T-lymphocytes
A pro-inflammatory cytokine that is made by pattern recognition receptors, and is cleaved from the pro-form by the NLRP3 inflammasome
What is IL-1 Beta
Prominent cytokine producer; is also a phagocyte with professional antigen presenting capabilities
What is a macrophage
NALP3 senses these signals in addition to PAMPs and assembles with an adaptor protein and caspase 1 to form the inflammasome
What are Damage-associated molecular patterns (DAMPs) /(cellular damage/stress)
The composition of the classical C5 convertase
C4b2b3b
The three types of professional antigen-presenting cells (APCs)
What are Macrophages, Dendritic Cells, and B lymphocytes (B-cells)
How leukocytes are recruited to the site of inflammation
What is (are) chemotaxis
The two transcription factors for Type I interferons
What are IRF3 and IRF7
The intracellular domain that interacts with an adaptor protein in the TLR4 signaling pathway
What is the Toll-interleukin receptor (TIR)?
What is C-reactive protein (CRP)?
A key role of antibodies
