科学家可能找到了阻止秃顶的方法

2025-03-30 17:31 by 人猿泰山之密林追踪

治疗秃顶甚至预防秃顶距离我们又近了一步。研究人员发现,负责头发生长的毛囊干细胞 (HFSC) 需要一种起到“保镖”作用的蛋白质 MCL-1。如果 MCL-1 因为压力、衰老、抗癌药物或遗传等降低水平,HSFC 会逐渐筋疲力尽最终走向死亡,也就不会长出新头发了。研究人员通过关闭生成 MCL-1 蛋白质的基因并剔除实验鼠的现有毛发演示了其作用。他们发现 HFSC 存活了一段时间,但最终因为触发压力信号 (P53)而走向死亡。研究报告发表在《Nature Communications》期刊上。最新发现为治疗和预防脱发开辟了新的研究方向。

That growth environment will include rising inflation and interest rates. Those upward shifts naturally accompany healthy growth periods as the demand for resources, products and services rise. Importantly, the Federal Reserve has laid out the rationale for not interfering with that natural growth transition.It's not exactly a fad, but there is a widespread willingness to pay up for a growth story. Classic fundamental analysis takes a back seat. Even negative earnings are ignored. In fact, positive earnings seem to be a limiting measure, producing the question, "Is that all you've got?" The preference is a vision of untold riches when the exciting story plays out as expected.
