Autophagy01:27

Autophagy

4.8K
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,...

Delivery Pathways to the Lysosome01:36

Delivery Pathways to the Lysosome

8.1K
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

Anxiety: Overview

467
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

Autophagic Cell Death01:18

Autophagic Cell Death

3.6K
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...

Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

7.9K
Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

Stress and Mental Health01:30

Stress and Mental Health

246
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
Individuals with depression often experience challenges in both their personal and professional...

Area of Science:

  • Neuroscience
  • Cell Biology
  • Behavioral Science

Background:

  • Social defeat stress can induce anxiety-like behaviors.
  • Understanding the neural mechanisms underlying these behaviors is crucial.

Purpose of the Study:

  • To investigate the role of mitophagy in BLA neurons projecting to the adBNST.
  • To elucidate the mechanism linking neuronal function to social defeat-induced anxiety.

Main Methods:

  • Utilized techniques to examine mitophagy in specific neuronal populations.
  • Assessed neurotransmission alterations in relevant neural circuits.
  • Evaluated anxiety-like behaviors following social defeat paradigms.

Main Results:

  • Identified excessive mitophagy in BLA neurons that synapse onto adBNST neurons.
  • Demonstrated that this excessive mitophagy leads to reduced neurotransmission.
  • Linked these cellular and synaptic changes to the manifestation of anxiety-like behaviors.

Conclusions:

  • Excessive mitophagy in BLA to adBNST projecting neurons is a key mechanism driving social defeat-induced anxiety.
  • Targeting mitophagy may offer therapeutic strategies for anxiety disorders.
