Blue™ Cytokine Reporter Cells
Blue™ Cytokine Reporter Cells is an expanding family of engineered cell lines designed to provide a simple, rapid
and reliable method to monitor the activation of signaling pathways induced by key cytokines. They allow to detect
these biologically active cytokines and can also be used to screen for compounds exhibiting agonist and antagonist
activities. Blue™ Cytokine Reporter Cells include B16-Blue™ and HEK-Blue™ Cells. B16-Blue™ and HEK-Blue™ Cells
are engineered murine melanoma and HEK293 cells, respectively. They express an inducible secreted embryonic
alkaline phosphatase (SEAP) reporter gene that can be quantitatively detected using QUANTI-Blue™, a SEAP
colorimetric detection medium. Blue™ Cytokine Reporter Cells express this SEAP reporter gene under the control
of specific promoters that are selectively activated by the cytokines or other immune modulators known to induce
the pathway of interest. Therefore, in the presence of the cytokine, agonist or antagonist compound, the pathway
is activated or inhibited modulating the SEAP activity. The amount of SEAP secreted in the cell supernatant can
be measured spectrophotometrically with QUANTI-Blue™.

B16-Blue™ IFN-a/b - Murine Type I IFNs Reporter Cells
➥ Monitor the JAK/STAT pathway
➥ Monitor the RIG-I/MDA-5 pathway
➥ Detection of murine IFN-a and IFN-b
Background
Interferon-alpha (IFN-a) and interferon beta (IFN-b), play an important
role in viral infections. They bind to an IFN receptor complex consisting oftwo alpha chains (IFNAR1 and IFNAR2) and recruit JAK1 and TyK2. Thesekinases phosphorylate STAT1 and STAT2 leading to the formation of theISGF3 complex. ISGF3 binds to IFN-stimulated response elements (ISRE)in the promoters of IFN-stimulated genes (ISG) to regulate theirexpression (figure 1). IFN-a and IFN-b are produced in response to viral
pathogen associated molecular patterns (PAMPs), such as viral RNA andDNA. These PAMPs are recognized by cytoplasmic pattern recognitionreceptors including the RNA helicases RIG-I or MDA5. Stimulation ofB16-Blue™ IFN-a/b cells with RIG-I/MDA-5 agonists, such as transfected
poly(I:C), triggers the secretion of IFN-a and IFN-b.
Description
B16-Blue™ IFN-a/b cells allow the detection of bioactive murine type I IFNs
by monitoring the activation of the JAK/STAT/ISGF3 pathway. They derivefrom the murine B16 melanoma cell line of C57B1/6 origin after stabletransfection with a SEAP reporter gene under the control of the IFN-a/b-
inducible ISG54 promoter. Stimulation of B16-Blue™ IFN-a/b cells with murine IFN-a or IFN-b, or
type I IFN inducers, such as tranfected poly(I:C) or poly(dA:dT), activatesthe JAK/STAT/ISGF3 pathway and triggers the subsequent production ofSEAP (figures 2&3). Levels of SEAP in the supernatant can be easilydetermined with QUANTI-Blue™, a medium that turns purple/blue in thepresence of SEAP and by reading the OD at 655 nm.

➥ Monitor the JAK/STAT/ISGF3 pathway
➥ Detection of human IFN-a and IFN-b
Background
Type I interferons, in particular interferon alpha (IFN-a) and interferon beta
(IFN-b), play a vital role in host resistance to viral infections. They signal
mainly through the JAK-STAT pathway. Following their production, IFN-a
and IFN-b bind to a common receptor (IFNAR) and recruit the Janus
kinases (JAK1 and TyK2). JAKs phosphorylate STAT1 and STAT2, whichthen dimerize and interact with IFN regulatory factor 9 (IRF9), forming acomplex named ISGF3. ISGF3 binds to IFN-stimulated response elements(ISRE) in the promoters of IFN-stimulated genes (ISG) to regulate theirexpression (figure 1).
Description
HEK-Blue™ IFN-a/b cells allow the detection of bioactive human type I
IFNs by monitoring the activation of the ISGF3 pathway. These cells weregenerated by stable transfection of HEK293 cells with the human STAT2and IRF9 genes to obtain a fully active type I IFN signaling pathway. Theother genes of the pathway (IFNAR1, IFNAR2, JAK1, TyK2 and STAT1) arenaturally expressed in sufficient amounts. The cells were further transfectedwith a SEAP reporter gene under the control of the IFN-a/b-inducible
ISG54 promoter.Stimulation of HEK-Blue™ IFN-a/b cells with human IFN-a or IFN-b
activates the JAK/STAT/ISGF3 pathway and subsequently induces theproduction of SEAP. Levels of SEAP in the supernatant can be easilydetermined with QUANTI-Blue™, a medium that turns purple/blue in thepresence of SEAP and by reading the OD at 655 nm (figure 2).Stimulation of HEK-Blue™ IFN-a/b cells with recombinant human IFN-a
can be blocked by anti-hIFN-a-IgA, a neutralizing monoclonal antibody of
the IgA isotype (see page 104).

➥ Monitor the JAK/STAT-6 pathway
➥ Detection of human IL-4 and human/murine IL-13
Background
The transcription factor STAT6 is activated primarily by two cytokineswith overlapping biologic functions, IL-4 and IL-13. It can also be activatedby IFN-a in a cell-specific manner. In non-hematopoietic cells, IL-4 and
IL-13 bind a receptor complex composed of the IL-4Ralpha andIL-13Ralpha1. Upon ligand binding, the receptor complex activates thereceptor-associated Janus kinases (JAK1 and Tyk2) leading to therecruitment of STAT6 and its phosphorylation. Activated STAT6 formshomodimers that translocate to the nucleus where they bind thepromoter of responsive genes inducing gene transcription.
Description
HEK-Blue™ IL-4/IL-13 cells allow the detection of bioactive IL-4 andIL-13 by monitoring the activation of the STAT-6 pathway. These cellswere generated by stable transfection of HEK293 cells with the humanSTAT6 gene to obtain a fully active STAT6 pathway. The other genes ofthe pathway are naturally expressed in sufficient amounts. The cells werefurther transfected with a SEAP reporter gene under the control of theIFNb minimal promoter fused to four STAT6 binding sites. HEK-Blue™
IL-4/IL-13 cells produce SEAP in response to IL-4 or IL-13 stimulationand to a lower extent IFN-a. The levels of SEAP secreted in the
supernatant can be easily determined with QUANTI-Blue™, a SEAPdetection medium (Figure 2).Stimulation of HEK-Blue™ IL-4/IL-13 cells with IL-4 or IL-13 can be blockedby the neutralizing monoclonal anti-hIL-4-IgA and anti-hIL-13-IgAantibodies, respectively (see page 104).

➥ Monitor the JAK/STAT-3 pathway
➥ Detection of human IL-6
Background
The proinflammatory cytokine IL-6 is one of the most importantmediators of fever and of the acute phase response. IL-6 exerts itsaction by first binding to the IL-6R. The complex of IL-6 and IL-6Rassociates with the signal-transducing membrane protein gp130, therebyinducing its dimerization. This leads to the activation by phosphorylationof the tyrosine kinases of the Janus family (JAK1, JAK2, and Tyk2).Activated JAKs induce the dimerization and translocation to the nucleusof STAT3 where it binds enhancer elements of IL-6-inducible genes.
Description
HEK-Blue™ IL-6 cells allow the detection of bioactive IL-6 bymonitoring the activation of the STAT-3 pathway. These cells weregenerated by stable transfection of HEK293 cells with the humanIL-6R gene. They were further transfected with a SEAP reporter geneunder the control of the IFN-b minimal promoter fused to four STAT3
binding sites. Upon IL-6 stimulation, HEK-Blue™ IL-6 cells trigger theactivation of STAT3 and the subsequent secretion of SEAP. SEAP canbe readily monitored when using the SEAP detection mediumQUANTI-Blue™.Stimulation of HEK-Blue™ IL-6 cells with recombinant human IL-6 can beblocked by anti-hIL-6-IgA, a neutralizing monoclonal antibody of the IgAisotype (see page 104).

➥ Monitor the TNF-a- and IL-1b-induced NF-kB and AP-1 pathways
➥ Detection of human and murine TNF-a and IL-1b(a)
Background
Tumor necrosis factor alpha (TNF-a) and interleukin 1 beta (IL-1b) are
proinflammatory cytokines produced in response to microbial infection.The common inflammatory responses of TNF-a and IL-1b are mediated
by interactions of these cytokines with distinct receptors: TNF-a binds
TNFR1 and TNFR2, IL-1b binds IL-1RI. Binding of these cytokines to their
receptors induces intracellular signaling. TNF-a signaling involves TRADD,
TRAF2 and RIP, while IL-1b signaling is mediated by MyD88, IRAK-1,
TRAF-6, and Rac1. Both signalings lead to the activation of thetranscription factors NF-kB and AP-1 (figure 1).
Description
HEK-Blue™TNF-a/IL-1b cells are designed to detect bioactive TNF-a and
IL-1b (and IL-1a) by monitoring the activation of the NF-kB pathway. HEK-Blue™ TNF-a/IL-1b cells derive from HEK293 cells. They
endogenously express the receptors for TNF-a and IL-1b and stably
express a SEAP reporter gene under the control of the IFN-b minimal
promoter fused to five NF-kB and five AP-1 binding sites.
HEK-Blue™ TNF-a/IL-1b cells secrete SEAP upon stimulation by human
TNF-a and IL-1b (figure 2). SEAP production is also detected in the
presence of murine TNF-a and IL-1b, and human or murine IL-1a. SEAP
levels can be readily determined using a SEAP detection medium, suchas QUANTI-Blue™ or HEK-Blue™ Detection medium.Stimulation of HEK-Blue™ TNF-a/IL-1b cells with recombinant human
TNF-a or IL-1b can be blocked by the neutralizing monoclonal anti-
hTNF-a-IgA or anti-hIL-1b-IgA antibody, respectively (see page 104).

➥ Monitor the IL-1b-induced NF-kB and AP-1 pathways
➥ Detection of human and murine IL-1b(a)
Background
Interleukin-1b (IL-1b) is an important mediator of the inflammatory response
to infection and injury. IL-1b binds to the type 1 IL-1 receptor (IL-1R) which
requires the IL-1 receptor accessory protein (IL-1RAcP) to transduce asignal. IL-1b signaling is mediated by MyD88, IRAK-1/2 and TRAF-6 leading
to the activation of NF-kB and AP-1 (figure 1).
Description
HEK-Blue™ IL-1b cells allow to detect bioactive IL-1b by monitoring the
activation of the NF-kB and AP-1 pathways. They derive from HEK-Blue™
TNF-a/IL-1b cells in which the TNF-a response has been blocked.
Therefore, HEK-Blue™ IL-1b cells respond specifically to IL-1b. They express
a SEAP reporter gene under the control of the IFN-b minimal promoter
fused to five NF-kB and five AP-1 binding sites.
Binding of IL-1b to its receptor on the surface of HEK-Blue™ IL-1b cells
triggers the IL1-R signaling pathway leading to the activation of NF-kB/
AP-1 and the subsequent production of SEAP. The levels of SEAP in thesupernatant can be easily monitored using QUANTI-Blue™.HEK-Blue™ IL-1b cells respond to IL-1b and also IL-1a (data not shown)
but do not respond to TNF-a (figure 2).
Stimulation of HEK-Blue™ IL-1b cells with recombinant human IL-1b can
be blocked by the neutralizing monoclonal anti-hIL-1b-IgA antibody (see
page 104),

receptor which requires the IL-1 receptor accessory protein (IL-1RAcP)to transduce a signal. IL-18 binds to an heterodimeric receptor consistingof IL-18R and IL-18 receptor accessory protein (IL18RAP). IL-1b and IL-
18 share common signaling pathways that involve MyD88, and TRAF-6leading to the activation of NF-kB and AP-1 (figure 1).
Description
HEK-Blue™ IL-18/IL-1b cells are designed to detect bioactive IL-18 and
IL-1b (and IL-1a) by monitoring the activation of the NF-kB and AP-1pathways. They were generated by stable transfection of HEK-Blue™
IL-1b cells with the gene encoding IL-18RAP. They express a SEAP
reporter gene under the control of the IFN-b minimal promoter fused
to five NF-kB and five AP-1 binding sites.
Stimulation of HEK-Blue™ IL-18/IL-1b cells with human IL-18 or IL-1b,
but not with human TNF-a, activates the NF-kB and AP-1 pathways
triggering the production of SEAP (figure 2). Levels of SEAP in thesupernatant can be easily determined with QUANTI-Blue™.Stimulation of HEK-Blue™ IL-18/IL-1b cells with recombinant human
IL-18 or IL-1b can be blocked by the neutralizing antibodies
anti-hIL-18-IgA and anti-hIL-1b-IgA, respectively (see page 104).

➥ Monitor the IL-33/IL-1b-induced NF-kB and AP-1 pathways
➥ Detection of IL-33 and IL-1b(a)
Background
Interleukin-33 (IL-33) is a member of the IL-1 family, a group of cytokinesthat play important roles in host defense, immune regulation andinflammation. IL-33 mediates its biological effects through ST2 (also knownas IL1RL1), a receptor expressed on Th2 and mast cells. IL-33 and ST2 forma complex with IL-1R accessory protein (IL-1RAcP), a signaling receptorsubunit that is also a member of the IL-1R complex. IL-33 signaling leads tothe activation of NF-kB and MAP kinases, and the production of Th2-
associated cytokines.

HEK-Blue™ TGF-b Cells - TGF-b Reporter Cells
➥ Monitor the TGF-b/Smad pathway
➥ Detection of human TGF-b
Background
Tumor growth factor-beta (TGF-b) belongs to a family of structurally
related cytokines that regulate a plethora of cellular functions, such asproliferation, apoptosis, differentiation and migration. TGF-b binds to a
type II receptor which recruits and activates a type I receptor. The type Ireceptor then phosphorylates receptor-regulated Smads (R-Smads), suchas Smad2 and Smad3, which associate with Smad4. R-Smad/Smad4complexes accumulate in the nucleus where they regulate the
transcription of target genes.
Description
HEK-Blue™ TGF-b cells allow the detection of bioactive TGF-b by
monitoring the activation of the TGF-b/Smad pathway. They were
generated by stable transfection of HEK293 cells with the human TGFBRI,Smad3 and Smad4 genes. They further express a SEAP reporter geneunder the control of the b-globin minimal promoter fused to three
Smad3/4-binding elements (SBE).Stimulation of HEK-Blue™ TGF-b cells with TGF-b induces the activation
of the TGF-b/Smad signaling pathway leading to the formation of a
Smad3/Smad4 complex. The heterocomplex enters the nucleus and bindsSBE sites inducing the production of SEAP (figure 1). The quantity of SEAPsecreted in the supernatant can be easily assessed using QUANTI-Blue™
(figure 2). TGF-b-mediated SEAP production can be blocked using a
neutralizing antibody, such as anti-hTGF-b-IgA (see page 104).

➥ Study CD40L-CD40 interactions
➥ Screen for molecules that interfere with CD40L-CD40 cross-talk
Background
CD40 ligand (CD40L) is a member of the tumor necrosis factor (TNF)family of cell surface interaction molecules. It is mainly expressed inCD4+-T cells and interacts with CD40 on antigen-presenting cells toregulate both humoral and cellular immune responses. CD40L-CD40interactions are thought to play an important role in the pathogenesis ofcertain diseases, including AIDS, Alzheimer’s disease and rheumatoidarthritis.
Description
HEK-Blue™ CD40L cells can serve to measure the bioactivity of CD40Lthrough the secretion of embryonic alkaline phosphatase (SEAP) uponNF-kB activation. These cells were generated by stable transfection of
HEK293 cells with the human CD40 gene and an NF-kB-inducible SEAP
construct. The SEAP construct consists of the SEAP reporter gene underthe control of the IFN-b minimal promoter fused to five NF-kB binding
sites. Binding of CD40L to its receptor CD40 triggers a signaling cascadeleading to the activation of NF-kB and the subsequent production of
SEAP (figure 1). CD40L-CD40 interaction can be monitored by assessingthe levels of SEAP using a SEAP detection assay, such as QUANTI-Blue™
(figure 2). HEK293 cells express endogenously the receptors for thecytokines IL-1b and TNF-a which share a common signaling pathway with
CD40L. Consequently, HEK-Blue™ CD40L cells also respond to IL-1b and
TNF-a. IL-1b- and TNF-a-mediated SEAP production can be blocked
using neutralizing antibodies, such as anti-hIL-1b-IgA and anti-hTNF-a-IgA
antibodies respectively (see page 104).
