Description

Receptor Binding

IL-17B binds specifically to IL-17RB but not IL-17R . It shares 88% sequence identity between humans and mice , enabling cross-species functional studies.

Biological Roles

  • Proinflammatory Effects: Stimulates TNF-α and IL-1β release in monocytes and IL-8 in hepatocytes .

  • Anti-inflammatory Modulation: Antagonizes IL-25-driven inflammation in colitis and asthma by suppressing IL-6 production in epithelial cells .

  • Tissue-Specific Expression: Highly expressed in the spinal cord, brain, and gastrointestinal tract .

Inflammatory Bowel Disease (IBD)

  • IL-17B deficiency exacerbates colitis in mice, increasing neutrophil infiltration and proinflammatory cytokines (e.g., S100A9) in macrophages .

  • Recombinant IL-17B administration reduces colitis severity by modulating myeloid cell responses .

Cancer and Bone Biology

  • Upregulated in aggressive breast cancer, promoting tumorigenicity via IL-17RB signaling .

  • Enhances vascular endothelial cell migration while inhibiting adhesion .

  • Expressed in bone collars and chondrocytes, influencing skeletal development and fracture repair .

Allergic Inflammation

  • Inhibits IL-25-mediated allergic asthma and parasitic defense pathways .

Therapeutic Potential

ConditionMechanismOutcome
ColitisSuppresses neutrophil infiltration and macrophage cytokines Reduced disease severity in murine models
Breast CancerEnhances IL-17RB signaling to promote tumor growth Potential oncotherapeutic target
ArthritisUpregulated in arthritic cartilage, exacerbating inflammation Contributes to joint destruction

Key Challenges and Future Directions

  • Dual Roles: IL-17B exhibits both pro- and anti-inflammatory effects depending on context .

  • Therapeutic Targeting: While promising in colitis, its role in cancer and arthritis requires careful modulation .

  • Mechanistic Gaps: The interplay between IL-17B and other IL-17 family members remains poorly understood .

Product Specs

Buffer
Lyophilized from a 0.2 µm filtered PBS, pH 7.4, containing 0.1% Tween-20 and 3% Trehalose.
Form
Lyophilized powder
Lead Time
5-10 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Reconstitution
We recommend centrifuging this vial briefly prior to opening to ensure the contents settle to the bottom. Reconstitute the protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL. We recommend adding 5-50% glycerol (final concentration) and aliquoting for long-term storage at -20°C/-80°C. Our default final glycerol concentration is 50%, which can be used as a reference.
Shelf Life
The shelf life depends on various factors including storage conditions, buffer ingredients, storage temperature, and the stability of the protein itself. Generally, the shelf life of the liquid form is 6 months at -20°C/-80°C, while the shelf life of the lyophilized form is 12 months at -20°C/-80°C.
Storage Condition
Store at -20°C/-80°C upon receipt. Aliquoting is necessary for multiple uses. Avoid repeated freeze-thaw cycles.
