Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

4.8K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized...

Autophagy01:27

Autophagy

5.6K
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,...

Autophagic Cell Death01:18

Autophagic Cell Death

4.2K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

Inflammatory Response I: Vascular and Cellular

15.7K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Area of Science:

  • Neuroscience
  • Cell Biology
  • Pathology

Background:

  • Autophagy plays a dual role in ischemic nerve tissue, offering protection at appropriate levels but causing cell death when excessive.
  • Inflammation is critical for nerve cell survival and neural tissue recovery post-ischemia.
  • A significant interaction exists between autophagy and inflammation in ischemic stroke pathogenesis.

Purpose of the Study:

  • To review recent advances on the role of autophagy in the post-stroke inflammatory response.
  • To elucidate the mechanisms by which autophagy modulates inflammation after ischemic stroke.
  • To explore the therapeutic potential of targeting the autophagy-inflammatory pathway for ischemic stroke treatment.

Main Methods:

  • Literature review of studies investigating autophagy and inflammation in ischemic stroke.
  • Analysis of molecular pathways involved, including mTOR, AMPK, inflammasomes, and NF-κB.
  • Examination of cellular markers such as LC3-II and Beclin-1.

Main Results:

  • Autophagy, via pathways like mTOR and AMPK, inhibits ischemic inflammation and inflammasome activation.
  • Inflammation can trigger autophagosome formation, with markers like LC3-II and Beclin-1 increasing.
  • Blocking autophagy can alleviate ischemic injury, while modulating microglial phenotype via NF-κB aids recovery.

Conclusions:

  • The interplay between autophagy and inflammation is crucial in ischemic stroke.
  • Targeting the autophagy-inflammatory pathway, potentially with drugs like resveratrol, offers a promising therapeutic strategy for ischemic stroke.
  • Further research into this pathway could lead to novel treatments for ischemic stroke.
