There is growing interest in the potential use of 5-HT(1A) receptor agonists as neuroprotective agents in stroke and traumatic brain injury. However, a new study using a recombinant 5-HT(1A) receptor cell line suggests that these agonists may promote as well as inhibit apoptotic responses. Because heterologously expressed receptors may couple promiscuously to inappropriate signal transduction pathways, the results should be interpreted with caution.
5-羟色胺(5-HT)1A受体激动剂作为神经保护剂在中风和创伤性脑损伤中的潜在应用正受到越来越多的关注。然而,一项使用重组5-HT1A受体细胞系的新研究表明,这些激动剂可能既促进又抑制凋亡反应。由于异源表达的受体可能会随意地与不适当的信号转导途径偶联,因此对结果的解释应谨慎。
