Beschreibung: Interleukin 33 (IL-33) is a pro-inflammatory cytokine from the IL-1 family. It binds to ST2 receptor and activates NF-κB and MAPK pathways. IL-33 is expressed by epithelial cells, smooth muscle cells, and fibroblasts in various tissues and organs, as well as resting basophils, mast cells, eosinophils, natural helper cells, group 2 innate lymphoid cells, dendritic cells, and activated macrophages (Schmitz <i>et al.</i>; Yasuda <i>et al.</i>). It contributes to allergic inflammation by stimulating production of the cytokines IL-4, IL-5, and IL-13, and stimulates host defense against microbial and viral infections (Liew; Yasuda <i>et al.</i>). In the central nervous system, IL-33 is produced by endothelial cells and astrocytes. It induces proliferation of microglia and mediates production of pro-inflammatory cytokines (Yasuoka <i>et al.</i>).

Beschreibung: Noggin binds to and antagonizes bone morphogenetic protein (BMP) ligands of the transforming growth factor beta (TGF-β) family. Noggin supports maintenance of undifferentiated human embryonic stem cells in vitro, and can be used to prevent spontaneous differentiation in the short term (Chaturvedi <i>et al.</i>). Noggin is essential for development of structures derived from ectoderm embryonic somite, skeletal patterning, and neurogenesis in vivo. It also influences chondrogenesis, osteogenesis, and joint formation (Krause <i>et al.</i>), and promotes dopaminergic differentiation of embryonic stem cells and subsequent survival of dopamine neurons (Chiba <i>et al.</i>).

Beschreibung: Interleukin 12 (IL-12p70) is a heterodimeric cytokine composed of p35 and p40 subunits. IL-12 is produced by monocytes, macrophages, dendritic cells, neutrophils, and B cells in response to bacterial products and cytokines such as IFN-γ. The IL-12 receptor is expressed on T, NK, and dendritic cells. Upon binding, IL-12 initiates signaling via the JAK/STAT signaling pathway and stimulates NK, B, and T cells to produce IFN-γ (Watford <i>et al.</i>). It also regulates cytokine synthesis, proliferation of T and NK cells, and stimulates differentiation of CD4+ and CD8+ T cells (Germann and Rüde). Mice that are deficient in IL-12 are susceptible to many intracellular pathogens and have impaired IFN-γ secretion, Th1 differentiation, and NK cytolytic activity; however, Th2 development and IL-4 production are enhanced (Watford <i>et al.</i>).

Beschreibung: Glial cell line-derived neurotrophic factor (GDNF) is a neurotrophic factor and a member of the tumor growth factor (TGF)-beta superfamily. The GDNF family of growth factors also includes neurturin, persephin, and artemin, which have seven conserved cysteine residues called cysteine-knots (Treanor <i>et al.</i>). GDNF family ligands signal through binding to specific GDNF-family receptor-α (GFRα) co-receptors and activate the RET receptor tyrosine kinase (Durbec <i>et al.</i>). Four different forms of GFRα co-receptors have been characterized (GFRα 1-4); GDNF binds specifically to GFRα1 prior to forming a complex with RET (Airaksinen and Saarma). GDNF is known to promote survival and morphological differentiation of midbrain dopaminergic neurons in both <i>in vivo</i> and in vitro studies and increases their high-affinity dopamine uptake (Granholm <i>et al.</i>; Lin <i>et al.</i>). GDNF has also been shown to have restorative effects on dying dopaminergic neurons in response to degenerative toxins (Aoi <i>et al.</i>). GDNF, together with Human Recombinant BDNF (brain-derived neurotrophic factor), BrainPhys™ Neuronal Medium, and other supplements, can be used to differentiate human pluripotent stem cell (hPSC)-derived neural progenitor cells into neurons (Bardy <i>et al.</i>).

Beschreibung: Interleukin 17A (IL-17A) is the founding member of the family of cytokines that includes Interleukin 17B through Interleukin 17F. It is a potent proinflammatory cytokine that plays a key role in defense against pathogens. IL-17A and IL-17F signal as homodimers or heterodimers through the same receptor, and activate NF-kB, MAPK, and C/EBP pathways (Gaffen). IL-17A receptor is expressed on a variety of cell types, including hematopoietic cell compartments. IL-17A is produced by T helper 17 cells, CD8+ T cells, γδ T cells, natural killer T cells, B cells, neutrophils, innate lymphoid cells and mesenchymal stromal cells (MSCs; Zenobia and amp; Hajishengallis; Mojsilovic <i>et al.</i>). IL-17A receptor is expressed at particularly high levels on stromal cells, including MSCs. IL-17A increases the frequency and the average size of colony-forming units-fibroblast derived from bone marrow, as well as the proliferation of bone marrow-derived MSCs. IL-17A suppresses osteogenic differentiation and bone formation of bone marrow-derived MSCs. The action of IL-17A on hematopoiesis is deeply reliant on the microenvironment and the induction of other regulators. In healthy mouse bone marrow, IL-17A stimulates myeloid and early stage erythroid progenitor cells but inhibits late stage erythroid progenitor cells (Mojsilovic <i>et al.</i>).

Beschreibung: Bone morphogenetic protein 4 (BMP-4) is a member of the highly conserved transforming growth factor β (TGF-β) superfamily. Mature BMP-4 is a disulfide-linked homodimeric protein consisting of two 116-amino-acid residue subunits, and is generated by the proteolytic removal of the signal peptide and propeptides (Xiao <i>et al.</i>). BMP-4 binds to type I and type II receptors on cells. This binding results in the phosphorylation of receptor 1, which in turn results in the phosphorylation of Smad proteins, which then go on to act as transcription factors (Zhang <i>et al.</i>). BMPs have been shown to be key regulators of embryogenesis and are known to play a role in the growth and differentiation of various cell types, including embryonic stem (ES) cells, induced pluripotent stem (iPS) cells, mesenchymal cells, epithelial cells, hematopoietic cells, and neuronal cells (Chadwick <i>et al.</i>; Graham <i>et al.</i>; Jones <i>et al.</i>; Lengerke <i>et al.</i>; Zhang <i>et al.</i>).

Beschreibung: The SARS-CoV-2 (spike protein) peptide pool is provided as two lyophilised mixtures (subpools) from the SARS-CoV-2 spike protein. Each subpool contains 158 peptides, for a total of 316 peptides. The virus attaches to the cell membrane of the host through the interaction between spike protein and angiotensin-converting enzyme 2 (ACE2) receptor, and the spike protein plays a critical role in viral entry. The subpools consist of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 1273 on the spike protein.

Beschreibung: Leukemia inhibitory factor (LIF) is an interleukin 6 class cytokine that regulates a broad variety of developmental functions. After LIF binds to the LIF receptor (LIFR), LIFR associates with gp130 and activates JAK/STAT and MAPK signaling (Auernhammer and Melmed; Suman <i>et al.</i>). LIFR activation of STAT3 is essential for maintaining the mouse embryonic stem cell phenotype (Niwa <i>et al.</i>). Produced by the endometrium, LIF plays an important autocrine and paracrine role in implantation by regulating proliferation, invasion, and differentiation of trophoblasts following blastocyst attachment (Auernhammer and Melmed; Suman <i>et al.</i>). Human LIF can be used for the maintenance of mouse embryonic stem cells; however, mouse LIF cannot bind to the human receptor, thus rendering mouse LIF inactive (Dahéron <i>et al.</i>). LIF is produced by CD4+ and activated regulatory T cells, and promotes Foxp3 expression, while repressing Th17 lineage-specific genes (Metcalfe). LIF is also secreted by mesenchymal stromal cells, where it supports hematopoiesis and immune modulation (Nasef <i>et al.</i>).
