干扰素-γ(IFN-γ)是一种有效的免疫调节细胞因子,其生理作用由细胞外基质调节。在这里,圆二色谱和荧光光谱技术被用来证明低分子量肝素和硫酸软骨素引起IFN-γ的二级和三级结构的显着变化。结果表明,肝素和硫酸软骨素通过引起IFN-γ二聚体的结构变化来调节IFN-γ活性。
Interferon-γ (IFN-γ) is a potent immunomodulatory cytokine whose physiological roles are modulated by the extracellular matrix. Here, circular dichroism and fluorescence spectroscopic techniques are used to demonstrate that low molecular weight heparin and chondroitin sulfate cause significant changes in secondary and tertiary structure of IFN-γ. The results suggest that heparin and chondroitin sulfate modulate IFN-γ activity by causing structural changes in the IFN-γ dimer.
