      | Vaxjo ID | 253 |  
      | Vaccine Adjuvant Name | IFNβ |  
      | Alternative Names | Type I Interferon beta |  
      | Adjuvant VO ID | VO_0005740 |  
      | Description | IFNβ is a type I interferon cytokine that enhances anti-tumor immune responses, particularly by promoting cross-priming of CD8⁺ T cells through dendritic cells. It's investigated here as a potent adjuvant in cancer vaccination strategies |  
      | Stage of Development | Research |  
      | Host Species for Testing | Mouse |  
      | Components | Cancer vaccination drives the generation of anti-tumor T cell immunity and can be enhanced by the inclusion of effective immune adjuvants such as type I interferons (IFNs) |  
      | Structure | Protein cytokine (~166 amino acids), signals via IFNAR1/IFNAR2 receptor complex. |  
      | Preparation | Recombinant IFNβ was either: Endogenously expressed by tumor cell lines (via viral transduction), or Injected as recombinant protein at 1×10⁵ IU per mouse during vaccination |  
      | Dosage | 2.5×10⁶ irradiated tumor cells plus 1×10⁵ IU IFNβ intraperitoneally per vaccination in mice. |  
      | Function | Therapeutically, vaccination with IFNβ delayed tumor progression when compared to vaccination without IFN. When vaccinated in combination with anti-PD-L1 checkpoint blockade therapy (CPB), the inclusion of IFNβ associated with more mice experiencing complete regression and a trend in increased overall survival. This work demonstrates the potent adjuvant activity of IFNβ, highlighting its potential to enhance cancer vaccination strategies alone and in combination with CPB |  
      | Safety | Well-tolerated in mice |
