Insights

Mitochondria-associated ER membranes (MAM) are crucial for microglia, the brain's immune cells, to regulate metabolism and immune responses. This review explores how MAM impacts microglial function and neurodegeneration.

Area of Science:

  • Neuroscience
  • Immunology
  • Cell Biology

Background:

  • Microglia are the central nervous system (CNS) resident immune cells.
  • They maintain tissue homeostasis through phagocytosis, cytokine production, and synapse remodeling.
  • Microglial functions are metabolically regulated, allowing adaptation to environmental cues.

Purpose of the Study:

  • To review the role of mitochondria-associated ER membranes (MAM) in microglial physiology.
  • To emphasize the influence of MAM on microglial immunometabolism.
  • To provide insights into CNS metabolic and immune function integration in neurodegeneration.

Main Methods:

  • Literature review of current research on MAM and microglia.
  • Synthesis of studies focusing on MAM's impact on microglial metabolism and function.
  • Analysis of MAM's role in the context of neurodegenerative diseases.

Main Results:

  • MAM are key sites for metabolic and signaling regulation in microglia.
  • MAM facilitate the exchange of calcium, lipids, and metabolites between the ER and mitochondria.
  • MAM are integral to microglial immunometabolism and adaptation.

Conclusions:

  • MAM play a critical role in regulating microglial immunometabolism.
  • Understanding MAM's function offers new insights into CNS immune responses.
  • MAM regulation is significant in the context of neurodegeneration.

Mitochondrial Membranes01:45

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

The Endoplasmic Reticulum01:43

The Endoplasmic Reticulum

The endoplasmic reticulum or ER makes up for more than half of the membranes in a cell and accounts for 10% of total cell volume. It is also the primary protein and lipid synthesis factory for most cell organelles, such as the Golgi apparatus, lysosomes, secretory vesicles, and the plasma membrane. Despite being the most extensive and functionally complex subcellular organelle, ER was the last to be discovered. After years of deliberation, Keith Porter and George Palade in the year 1954,...

The Inner Mitochondrial Membrane01:28

The Inner Mitochondrial Membrane

The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria.  In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...

Endoplasmic Reticulum01:39

Endoplasmic Reticulum

The Endoplasmic Reticulum (ER) in eukaryotic cells is a substantial network of interconnected membranes with diverse functions, from calcium storage to biomolecule synthesis. A primary component of the endomembrane system, the ER manufactures phospholipids critical for membrane function throughout the cell. Additionally, the two distinct regions of the ER specialize in the manufacture of specific lipids and proteins.

Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Insertion of Multi-pass Transmembrane Proteins in the RER01:29

Insertion of Multi-pass Transmembrane Proteins in the RER

The rough ER membrane synthesizes, assembles, and embeds transmembrane proteins in diverse topologies. These proteins function as transporters or channels and can remain in the ER membrane or are sent to the Golgi complex, lysosome, and cell membrane.
The multipass transmembrane proteins are the type IV integral membrane proteins with multiple topogenic sequences determining their spatial arrangement in the ER membrane. Nearly all multipass proteins lack a cleavable signal sequence and use...
