Mitochondria

18.3K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Atherosclerosis I: Introduction

519
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Mitochondrial Membranes

15.5K
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,...

Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

10.5K
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,...

The Inner Mitochondrial Membrane01:28

The Inner Mitochondrial Membrane

4.2K
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...

Area of Science:

  • Cardiovascular Biology
  • Cellular Metabolism
  • Immunology

Background:

  • Macrophages are crucial in the development of atherosclerotic cardiovascular diseases.
  • Mitochondria are essential for macrophage metabolic and signaling functions.
  • Mitochondrial dynamics, including fusion, fission, biogenesis, and mitophagy, regulate mitochondrial function.

Purpose of the Study:

  • To review the diverse roles of macrophage mitochondria in atherosclerosis.
  • To explore mitochondria as potential biomarkers for atherosclerosis.
  • To discuss how mitochondrial functions are integrated with other cellular processes in macrophages within atherosclerotic plaques.

Main Methods:

  • Literature review of past and emerging research on macrophage mitochondria in atherosclerosis.
  • Analysis of mitochondrial metabolic diversity and signaling platforms.
  • Examination of mitochondrial dynamics and inter-organelle communication (e.g., MAMs).

Main Results:

  • Mitochondria are central to macrophage effector functions in atherosclerosis, influencing metabolic and signaling pathways.
  • Mitochondrial metabolic diversity and signaling integration are critical.
  • Mitochondrial functions, including dynamics and communication, are altered in atherosclerotic macrophages.

Conclusions:

  • Mitochondrial metabolic and signaling functions are integral to macrophage behavior in atherosclerosis.
  • Perturbations in mitochondrial dynamics and communication are observed in atherosclerotic macrophages.
  • Further understanding of these integrated processes could yield novel therapeutic targets for atherosclerosis.
