概括

怀孕期间小鼠的心脏淋巴细胞发生变化,但并非所有菌株都会发生变化. 怀孕的BALB/cJ小鼠显示淋巴血管缩小,而C57BL/6J小鼠没有出现这些变化.

科学领域:

心血管生物学心血管生物学
淋巴系统研究淋巴系统研究
怀孕生理学怀孕生理学

背景情况:

心脏淋巴血管在响应生理和病理心血管变化时动态重塑.
怀孕涉及显著的心血管适应,以支持胎儿发育,但心脏淋巴反应在这个时期是不太了解.

研究的目的:

调查和描述怀孕期间心脏淋巴血管系统的形态变化.
为了比较两个基因不同的小鼠菌株C57BL/6J和BALB/cJ之间的这些变化.

主要方法:

使用全山免疫光标签用于心脏淋巴细胞可视化.
使用定量形态测量分析来评估淋巴血管的参数.
研究了C57BL/6J和BALB/cJ菌株的孕妇和非孕妇小鼠在孕期晚期 (孕期17.5日).

主要成果:

C57BL/6J小鼠表现出妊娠诱导的心脏缩,心脏淋巴血管结构没有显著改变.
BALB/cJ小鼠没有显示妊娠诱导的心脏缩.
怀孕的BALB/cJ小鼠在心脏淋巴细胞中表现出显著的形态变化,包括淋巴细胞的长度减少,终点数减少,心脏腹部表面的分支点结合减少.

结论:

怀孕期间心脏淋巴重塑是复杂的,受遗传和生理因素的影响.
在BALB/cJ小鼠中缺少心脏缩与显著的心脏淋巴变化相关,与C57BL/6J小鼠不同.
这项研究为怀孕后期心脏淋巴细胞异型重塑提供了新的见解.

Imbalances in Cardiac Output

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Pathophysiology of Heart Failure

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...
