Ischemic stroke is one of the leading causes of disability and death globally, with a rising incidence in younger age groups. It is well known that maternal diet during pregnancy and lactation is vital for the early neurodevelopment of offspring. One-carbon (1C) metabolism, including folic acid and choline, plays a vital role in closure of the neural tube in utero. However, the impact of maternal dietary deficiencies in 1C on offspring neurological function following ischemic stroke later in life remains undefined. The aim of this study was to investigate inflammation in the blood and brain tissue of offspring from mothers deficient in dietary folic acid or choline. Female mice were maintained on either a control or deficient diet prior to and during pregnancy and lactation. When offspring were 3 months of age, ischemic stroke was induced. One and a half months later, blood and brain tissue were collected. We measured levels of matrix metalloproteases (MMP)-2 and 9 in both plasma and brain tissue, and reported reduced levels of MMP-2 in ChDD male offspring in both tissue types. No changes were observed in MMP-9. This observation supports our working hypothesis that maternal dietary deficiencies in folic acid or choline during early neurodevelopment impact the levels of inflammation in offspring after ischemic stroke.
缺血性脑卒中是全球范围内导致残疾和死亡的主要原因之一,其在年轻人群中的发病率呈上升趋势。众所周知,母亲在妊娠和哺乳期的饮食对于后代的早期神经发育至关重要。一碳(1C)代谢,包括叶酸和胆碱,在胎儿神经管闭合中起着至关重要的作用。然而,母体饮食中 1C 缺乏对后代在生命后期发生缺血性脑卒中后的神经功能的影响仍未明确。本研究旨在研究母体饮食中缺乏叶酸或胆碱的后代的血液和脑组织中的炎症反应。雌性小鼠在妊娠和哺乳期之前和期间分别维持在对照或缺乏饮食条件下。当后代 3 个月大时,诱导缺血性脑卒中。一个半月后,收集血液和脑组织。我们测量了血浆和脑组织中基质金属蛋白酶(MMP)-2 和 9 的水平,并报告了 ChDD 雄性后代在两种组织类型中 MMP-2 水平降低。MMP-9 未发生变化。这一观察结果支持我们的工作假设,即早期神经发育过程中母体饮食中缺乏叶酸或胆碱会影响缺血性脑卒中后后代的炎症水平。
