General description
IFN β （干扰素 β）来自细胞因子1型干扰素家族。
干扰素 β （IFN-β）具有信号肽区域。含相对更多的疏水残基，与IFN-α的同源性达30％。
编码干扰素 β (Infb1) 的基因位于小鼠 4 号染色体。
Application
小鼠干扰素 β 可用于：
- 刺激骨髓来源的树突状细胞（BMDC）
- 作为细胞因子刺激足细胞分化
- 刺激脾细胞
小鼠干扰素β可用于：
- 通过 体外 刺激骨髓来源的巨噬细胞、树突状细胞和CD11c+ 肺巨噬细胞，诱导激活胆固醇25-羟化酶
- 刺激脾细胞，研究IFN-的分泌和调节γ
- 鼻内预处理新生小鼠，研究其对 鼠李糖乳杆菌 GG（LGG）保护作用的影响
- 作为标准品，处理 MEF-Mx2-luc-BKO报告细胞系，在人5型腺病毒 (HAdV-C5)的应答中，检测IFN-β 。
Biochem/physiol Actions
具有抗病毒、抗增殖、免疫调节和促炎活性的细胞因子。
在病毒感染的情况下，IFN β（干扰素β）会被上调并在先天抗病毒应答中起关键作用。它对于消炎作用也很重要。
干扰素 β (IFN-β）抑制淋巴细胞中多种促炎细胞因子，包括白介素1β（IL-1β）和肿瘤坏死因子 α （TNF-α）。 还有助于合成与白介素IL-10和IL-1受体相关的拮抗剂。IFN-β 下调干扰素 γ 的产生，但增强转化生长因子 β1的表达。 在治疗类风湿性关节炎 和复发缓解型多发性硬化（MS）方面，具有潜力。
干扰素 β 在人白细胞抗原（HLA）基因表达的激活中起作用。 在细菌感染时作为信使。
Physical form
溶液含20 mM HEPES，pH 6.0、0.5 M NaCl、6% 甘油和0.1%牛血清白蛋白。
Analysis Note
生物学活性是使用带有脑心肌炎病毒的小鼠L929细胞通过细胞病变效应抑制检测而被确定的。50％的细胞病变效应是利用约1 单位/ml的干扰素而产生的。相关单位是根据小鼠干扰素β的NIH国际标准参考标准确定的。

Type I interferons (IFN-I), such as IFN-α and IFN-β are important messengers in the host response against bacterial infections. Knowledge about the role of IFN-I in infections by nontuberculous mycobacteria (NTM) is limited. Here we show that macrophages infected with
ENU-induced mutation in USP18 causes hyperactivation of IFN-alphabeta signalling and suppresses STAT4-induced IFN-gamma production resulting in increased susceptibility to Salmonella Typhimurium

Podocytes are terminally differentiated renal cells, lacking the ability to regenerate by proliferation. However, during renal injury, podocytes re-enter into the cell cycle but fail to divide. Earlier studies suggested that re-entry into cell cycle results in loss of podocytes
