FTY720是一种免疫抑制多发性硬化(MS)药物,可刺激神经保护性脑源性神经营养因子(BDNF)的表达。体内临床前数据表明,FTY720可能对治疗帕金森氏症患者有益,尽管其免疫抑制作用可能会限制其疗效。两个新的FTY720-衍生物FTY720-C2和FTY720-Mitoxy也能刺激BDNF的表达,并像FTY720一样进入大脑,但不是磷酸化的,这表明它们不会产生FTY720样的免疫抑制。以FTY720为阳性对照,我们测量了低剂量和高剂量的FTY720衍生物,它们不会刺激FTY720样淋巴细胞减少或免疫抑制信号。这些发现支持对这些衍生物作为潜在的帕金森病新疗法的进一步临床前评估。
FTY720 is an immunosuppressive multiple sclerosis (MS) drug that stimulates the expression of neuroprotective brain-derived-neurotrophic-factor (BDNF). In vivo preclinical data suggest that FTY720 could be beneficial for treating Parkinson’s patients, though its immunosuppressive effects might limit its efficacy. Two novel FTY720-derivatives, FTY720-C2 and FTY720-Mitoxy, also stimulate BDNF expression and enter brain like FTY720 but are not phosphorylated, suggesting they will not produce FTY720-like immunosuppression. Using FTY720 as a positive control, we measured low and high dose FTY720-derivatives, which did not stimulate FTY720-like lymphopenia or immunosuppressive signaling. These findings support the further preclinical assessment of the derivatives as potential novel Parkinson’s therapies.
