Autophagy01:27

Autophagy

5.9K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

5.3K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Ischemic Heart Disease: Overview

3.5K
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Cardiac Output and Stroke Volume01:11

Cardiac Output and Stroke Volume

5.0K
Cardiac output (CO) is an integral aspect of human physiology, reflecting the heart's efficiency and responsiveness to the body's needs. It represents the volume of blood that the left or right ventricle ejects into the aorta or pulmonary trunk each minute. The CO is calculated by multiplying the heart rate (HR)—the number of heartbeats per minute—by the stroke volume (SV)—the amount of blood pumped out with each heartbeat.
In an average resting adult male, the typical cardiac...

Cardiac Output II: Effect of Stroke Volume on Cardiac Output01:22

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

3.6K
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Area of Science:

  • Cellular Biology
  • Neuroscience
  • Pathology

Background:

  • Autophagy is a fundamental cellular catabolic pathway crucial for maintaining homeostasis by degrading damaged components.
  • Evidence indicates autophagy activation in brain cells (neurons, glia, microvasculature) during ischemic stroke.
  • The precise function and molecular mechanisms of autophagy in ischemic stroke are not fully understood.

Purpose of the Study:

  • To comprehensively review autophagy regulation in brain cells under ischemic stress.
  • To elucidate the role of autophagy in cerebral ischemic preconditioning, perconditioning, and postconditioning.
  • To explore the interplay between autophagy and other cell death pathways and cellular stresses in stroke.

Main Methods:

  • Literature review of studies on autophagy in ischemic stroke.
  • Analysis of molecular mechanisms regulating autophagy in neurons, glia, and brain microvascular cells.
  • Examination of the crosstalk between autophagy, apoptosis, necroptosis, oxidative stress, and organelle dysfunction.

Main Results:

  • Autophagy is activated in multiple brain cell types during ischemic stroke.
  • Autophagy is implicated in the pathological processes of cerebral ischemic conditioning.
  • A complex crosstalk exists between autophagy, programmed cell death (apoptosis, necroptosis), and cellular stresses (oxidative, mitochondrial, ER) in stroke.

Conclusions:

  • Autophagy plays a significant, albeit complex, role in the response to ischemic stroke.
  • Understanding autophagy's role is critical for developing novel therapeutic strategies for stroke.
  • Further research is needed to fully elucidate the molecular intricacies of autophagy in cerebral ischemia.
