Introduction to Membrane Traffic

6.4K
The ER, Golgi apparatus, endosomes, and lysosomes work in tandem to modify, sort, and package proteins and lipids. An integrated membrane trafficking network facilitates the back and forth shuttling of molecules within different organelles in the same cell or across the cell membrane.
The transport of soluble and membrane proteins is mediated by transport vesicles that collect cargo from one cellular compartment and deliver it to another by fusing with the target organelle membrane. The Rab...

Export of Misfolded Proteins out of the ER01:32

Export of Misfolded Proteins out of the ER

3.3K
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...

Intracellular Movement of Viruses and Bacteria01:10

Intracellular Movement of Viruses and Bacteria

2.7K
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

Recycling Endosomes and Transcytosis00:58

Recycling Endosomes and Transcytosis

2.5K
The recycling endosome, also known as the endosomal recycling compartment (ERC), is a part of the slow-recycling process of the endocytic pathway. Molecules internalized through receptor-mediated endocytosis are either degraded in the lysosomes or are recycled to the plasma membrane through the fast- or slow-recycling route.
The recycling endosome is not a single organelle but an extensively tubulated network of recycling pathways. It functions in storing molecules or transporting them across...

Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

3.0K
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,...

Area of Science:

  • Cell Biology
  • Microbiology
  • Infectious Diseases

Background:

  • Eukaryotic cell membranes regulate molecular transport.
  • Intracellular bacterial pathogens invade host cells, requiring significant membrane remodeling.
  • Cytoskeleton dynamics have been studied for membrane remodeling, but membrane origin was less explored.

Purpose of the Study:

  • To review recent findings on how bacterial pathogens reroute membrane trafficking.
  • To highlight emerging themes in pathogen-driven membrane acquisition.
  • To identify open questions for future research in bacterial virulence and membrane trafficking.

Main Methods:

  • Literature review of recent studies on bacterial pathogens and host membrane trafficking.
  • Analysis of examples illustrating pathogen-induced membrane rerouting.
  • Synthesis of emerging themes and future research directions.

Main Results:

  • Bacterial pathogens actively co-opt host membrane trafficking pathways.
  • Membrane trafficking is essential for providing membranes during pathogen invasion, intracellular growth, and dissemination.
  • Pathogen strategies for membrane acquisition are diverse and stage-specific.

Conclusions:

  • Pathogen-induced membrane trafficking is critical for intracellular bacterial survival and spread.
  • Understanding these mechanisms offers insights into both bacterial virulence and fundamental cell biology.
  • Pathogens serve as valuable tools for studying host-pathogen interactions and membrane dynamics.
