一般說明
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。
應用
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ß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 。
生化/生理作用
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。
具有抗病毒、抗增殖、免疫调节和促炎活性的细胞因子。
外觀
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。
分析報告
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。

Rapid upregulation of interferon beta (IFN-β) expression following virus infection is essential to set up an efficient innate antiviral response. Biological roles related to the antiviral and immune response have also been associated with the constitutive production of IFN-β in

HLA class I and II molecules play a central role in regulating host immune responses against microbial infections because they present foreign antigens to CD8+ and CD4+ T lymphocytes, respectively. Many cytokines, especially interferons (IFN), are known to upregulate human

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

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

Cytogenetic analyses of non-small cell lung cancer have revealed deletions of the short arm of chromosome 9 with breakpoints at 9p11-pter in a significant proportion of tumors. Recent evidence suggests that homozygous loss of the interferon (IFN) and methylthioadenosine phosphorylase
