The dipeptidic dihydroxyethylene isostere (27, 3R , 4R , 5S )-5-tert -butyloxy-carbonylamino-3,4-dihydroxy-2-isopropyl-3,4-O,O -isoprop-ylidene-6-cyclohexyl-hexanoic acid, 15 , is a representative building block of an important class

腺相关病毒高分论文应用案例

和免疫抑制及其机制。研究发现阿黑皮素原（POMC）经切割会产生α促黑激素（α-MSH），α-MSH 则通过相应的受体 MC1R—MC5R 发挥生物学功能。研究结果发现，MC5R 与 α-MSH 促进肿瘤发展密切相关，并提示 MC5R 是癌症免疫治疗非常有前景的一个靶点。值得注意的是，汉恒生物提供的腺相关病毒 HBAAV2/9-Hspa9 shPOMC-GFP 成功敲低了小鼠垂体中的 POMC，为作者阐明相关机制提供了有力的病毒载体工具。 下面我们一起来看看作者是如何探索其中的机制： 作者首先研究

Functional Analysis of Human D1 and D5 Dopaminergic G Protein-Coupled Receptors: Lessons from Mutagenesis of a Conserved Serine Residue in the Cytosol

In mammals, dopamine G protein-coupled receptors (GPCR) are segregated into two categories: D1-like (D1R and D5R) and D2-like (D2Rshort , D2Rlong , D3R, and D4R) subtypes. D1R and D5R are primarily coupled to stimulatory heterotrimeric GTP
