TheRoleofEosinophilsintheChemokineNetworkofAllergy
The inflammatory response associated with asthma is characterized by the recruitment of eosinophils from the bronchial microcirculation in response to the regulated local production of chemoattractant molecules . Although several chemical mediators are active upon eosinophils in vitro, a central role in eosinophil accumulation in vivo is emerging for the C-C chemokine eotaxin, which was first identified in a guinea p......阅读全文

JAMA－Network－Open：细胞衰老会伴随大脑结构的改变
端粒是染色体末端的保护帽，它会随着细胞分裂而变短。如果端粒长度变得太短，以至于它们所保护的基因可能被破坏，那么细胞就会停止分裂和更新。这种机制是我们机体衰老的方式之一。 因此，端粒长度被认为是一个人的生物学年龄的标志。对于两个具有相同年龄的人，端粒较短的人患与年龄有关的疾病的风险增加，甚至寿命
