在妈妈被诊断出患有癌症的3个月后，她被送进了重症监护室（ICU）。就在我即将和项目负责人因一项帮助我过渡到教师职位的资助而见面的10分钟前，我得知了这个消息。在最后一刻取消见面是不专业的。但当我疯狂地把东西扔进行李箱时，我知道自己无法全身心投入。所以，我给项目负责人发了封邮件，解释了情况。她立即回信，让我专注于家庭。后来，当我妈妈离开重症监护室时，我仍然心烦意乱，无法见面。项目负责人重述了一遍她的信息：“未来几周的总体目标就是做一个好女儿，研究可以再等等。”她的话成为了我的人生路标。自从妈妈2020年被诊断出癌症以来，她完成了每

Enhancement of endogenous midbrain neurogenesis by microneurotrophin BNN-20 after neural progenitor grafting in a mouse model of nigral degeneration

We have previously shown the neuroprotective and pro-neurogenic activity of microneurotrophin BNN-20 in the substantia nigra of the “weaver” mouse, a model of progressive nigrostriatal degeneration. Here, we extended our investigation in two clinically-relevant ways. First, we assessed the effects of BNN-20 on human induced pluripotent stem cell-derived neural progenitor cells and neurons derived from healthy and parkinsonian donors. Second, we assessed if BNN-20 can boost the outcome of mouse neural progenitor cell intranigral transplantations in weaver mice, at late stages of degeneration. We found that BNN-20 has limited direct effects on cultured human induced pluripotent stem cell-derived neural progenitor cells, marginally enhancing their differentiation towards neurons and partially reversing the pathological phenotype of dopaminergic neurons generated from parkinsonian donors. In agreement, we found no effects of BNN-20 on the mouse neural progenitor cells grafted in the substantia nigra of weaver mice. However, the graft strongly induced an endogenous neurogenic response throughout the midbrain, which was significantly enhanced by the administration of microneurotrophin BNN-20. Our results provide straightforward evidence of the existence of an endogenous midbrain neurogenic system that can be specifically strengthened by BNN-20. Interestingly, the lack of major similar activity on cultured human induced pluripotent stem cell-derived neural progenitors and their progeny reveals the in vivo specificity of the aforementioned pro-neurogenic effect.
