ILCs
NK cells
Complement
Cytokines
100

T/F: ILCs express clonally distributed diverse antigen receptors

False: They do not express clonally distributed TCRs

100

T/F: NKs express diverse, clonally distributed antigen receptors 

False.  They use germline DNA-encoded receptors

100

This pathway is triggered by mannose-binding lectin (MBL)

Lectin pathway

100

Adalimumab, etanercept, and infliximab are therapies for RA, PsA, AS, and IBD that target this cytokine

TNF

200

This ILC uses transcription factor GATA-3 for differentiation

ILC2

200

The effect functions of NK cells are to kill infected cells and produce this cytokine, which activates macrophages

IFN-g

200

C6, C7, C8, and C9 assemble into a membrane pore called this

Membrane attack complex

200

Tocilizumab is this cytokine receptor antagonist; this cytokine stimulates Th17 differentiation

IL-6
300

ILC3s produce IL-22 and/or IL-17 and express RORgt, like these helper cells

Th17 cells

300

NK cells respond to these cytokines produced by macrophages

IL-12 and IL-15

300

The classical pathway starts with this plasma protein that detects antibodies bound to microbial surfaces

C1q

300

Complete LOF mutations in the gene for this cytokine or its receptors cause severe, treatment-refractory VEO-IBD

IL-10

400

These cytokines activate ILC1s to produce IFN-g for defense against viruses

IL-12 and IL-18

400

This activating receptor on NK cells is a low-affinity receptor for IgG (IgG1 and IgG3) and kills infected cells coated with antibodies via antibody-dependent cell-mediated cytotoxicity

CD16 (FcgRIIIA)

400

These cleavage products are also know as anaphylatoxins

C3a and C5a

400
This recombinant type II interferon is an FDA-approved immunomodulatory therapy used in prophylaxis for chronic granulomatous disease

Interferon-gamma

500

Lymphoid tissue-inducer (LTi) cells are a subtype of these ILCs and express lymphotoxin-a and TNF

ILC3s

500

The NKG2D receptor associates with this signaling subunit that stimulates NK cell cytotoxicity against target cells

DAP10

500

These 3 pentraxins can bind C1q and initiate the classical pathway

CRP, SAP, PTX3

500

Emapalumab is a monoclonal antibody that binds and neutralizes this cytokine for treatment of primary HLH and MAS

Interferon-gamma
