Export of Misfolded Proteins out of the ER01:32

Export of Misfolded Proteins out of the ER

3.5K
After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...

Fusion of Secretory Vesicles with the Plasma Membrane01:26

Fusion of Secretory Vesicles with the Plasma Membrane

10.8K
Proteins and neurotransmitters in secretory vesicles can be released from a cell upon vesicle docking, priming, and fusion with the plasma membrane. Vesicles are docked and primed in preparation for the quick exocytosis of their contents in response to a stimulus. The fusion process is mainly carried out by a SNAP Receptor or SNARE complex, consisting of synaptobrevin, syntaxin-1, and SNAP-25.
In 1993, Jim Rothman proposed that the antiparallel pairing of vesicular and transmembrane SNAREs, or...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

6.1K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

Area of Science:

  • Neuroscience
  • Cell Biology
  • Molecular Biology

Background:

  • Synapse elimination is crucial for nervous system development and function.
  • Dysregulation of synapse elimination is implicated in neuropathologies.
  • MFG-E8 is a secreted glycoprotein known for its role in phagocytosis.

Purpose of the Study:

  • To review the known direct and indirect effects of MFG-E8 on synapse elimination.
  • To propose potential novel mechanisms of MFG-E8 in synapse elimination, including cytoskeletal reorganization.
  • To highlight open questions regarding the conditions and regulation of MFG-E8-mediated synapse elimination.

Main Methods:

  • Literature review of existing studies on MFG-E8 and synapse elimination.
  • Analysis of MFG-E8's established functions in phagocytosis and its potential roles in the nervous system.
  • Synthesis of evidence to propose new hypotheses regarding MFG-E8's mechanisms.

Main Results:

  • MFG-E8's role in synapse elimination may extend beyond simple opsonization.
  • MFG-E8 might influence synapse elimination through cytoskeletal reorganization in neurons and glial cells.
  • The precise conditions and regulatory mechanisms of MFG-E8 in the nervous system require further investigation.

Conclusions:

  • MFG-E8 has diverse roles in the nervous system, potentially impacting synapse elimination through multiple pathways.
  • Further research is needed to elucidate the context-dependent functions of MFG-E8 in synapse elimination.
  • Understanding MFG-E8's role is critical for addressing neuropathologies associated with synapse dysregulation.
