研究问题

From a biological perspective, inflammation is an adaptive response to damaging agents aimed at restoring tissue homeostasis.

方法

Once the iPSC cultures reached 60–80% confluence, the iPSC maintenance medium, StemMACS XF (Miltenyi Biotec, Auburn, CA, USA), was replaced with Neurobasal Medium (Thermo Fisher Scientific, Grand Island, NY, USA) supplemented with a cocktail of factors promoting neural differentiation: Noggin, 80 ng/mL (Gibco, Grand Island, NY, USA); 1% B-27 and 1% N-2 (both Gibco, Grand Island, NY, USA); and SB431542, 10 μM (Selleck Chemicals, Houston, TX, USA).;Uncommitted NPs at passages 2–4 were transferred to Neurobasal Medium supplemented with Shh, 100 ng/mL (PeproTech, Rocky Hill, NJ, USA); FGF8, 20 ng/mL (PeproTech, Rocky Hill, NJ, USA); and Purmorphamine, 10 μM (Stemgent, Cambridge, MA, USA) for 10 days.;(ii) Generation of differentiated neurons: Shh, FGF8, and Pur were replaced in the culture medium with GDNF, 20 ng/mL and BDNF, 20 ng/mL (both PeproTech, Cranbury, NJ, USA); Forskolin, 4 μM (Stemgent, Cambridge, MA, USA); and ascorbic acid, 200 μM (PanEco, Moscow, RF).;Cell nuclei were counterstained with 0.1 μg/mL DAPI (Sigma-Aldrich, Saint Louis, MO, USA) in PBS for 10 min, followed by…

核心结论

Once the iPSC cultures reached 60–80% confluence, the iPSC maintenance medium, StemMACS XF (Miltenyi Biotec, Auburn, CA, USA), was replaced with Neurobasal Medium (Thermo Fisher Scientific, Grand Island, NY, USA) supplemented with a cocktail of factors promoting neural differentiation: Noggin, 80 ng/mL (Gibco, Grand Island, NY, USA); 1% B-27 and 1% N-2 (both Gibco, Grand Island, NY, USA); and SB431542, 10 μM (Selleck Chemicals, Houston, TX, USA).;For differentiation toward the glial lineage, the same NPs at passages 2–4 were transferred to Neurobasal Medium supplemented with FGF2, 10 ng/mL (Gibco, Grand Island, NY, USA); heregulin, 200 ng/mL (Thermo Fisher Scientific, Waltham, MA, USA); IGF-1, 10 ng/mL (ProSpec, East Brunswick, NJ, USA); activin A, 10 ng/mL (Gibco, Grand Island, NY, USA), N-2 (1%) and B-27 (1%) for 28 days.;Cells grown adherently in Petri dishes were rinsed with PBS… ‖ 结论:We identified cell-type-specific receptor expression in PARK2-mutant cells, and also observed trends toward distinct expression patterns in PD cells carrying mutations in other genes, including GBA1 and LRRK2, which may suggest an influence of genetic background on resolvin receptor expression.

局限

In addition to statistically significant differences, we also considered trends in gene expression, which should be interpreted with caution.

对本项目的价值

★★☆☆☆ 脑老化是最大未满足需求,也是终点最难量化的领域;biomarker 与认知读数选择最敏感。设计 Meta 分析、单细胞。

B 级证据分级:B 级(同行评议临床前研究,主要为动物模型)

本文核心结论来自动物模型或体外细胞学,属临床前证据,不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义,与人类临床结局之间仍有距离。
