Intracellular Movement of Viruses and Bacteria01:10

Intracellular Movement of Viruses and Bacteria

3.0K
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...

Receptor-mediated Endocytosis01:20

Receptor-mediated Endocytosis

10.2K
Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

One well-characterized example of receptor-mediated endocytosis is the...

Colonisation of Pathogens01:25

Colonisation of Pathogens

72
Pathogen colonization of host tissues is a critical step in the development of infectious diseases. Various pathogenic microorganisms, including bacteria, fungi, viruses, and protozoa, have evolved complex strategies to attach to, invade, and persist within host environments. These mechanisms enable pathogens to establish infections, evade immune responses, and resist antimicrobial treatments.Attachment to Host CellsIn bacteria, colonization typically begins with adherence to host epithelial...

Recycling Endosomes and Transcytosis00:58

Recycling Endosomes and Transcytosis

2.7K
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...

Adherens Junctions01:24

Adherens Junctions

5.8K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

Area of Science:

  • Cell Biology
  • Immunology
  • Microbiology

Background:

  • Pathogens manipulate host cellular processes for infection.
  • The small GTPase RAB11 is vital for vesicular trafficking and host immunity.
  • RAB11, with the exocyst complex, directs cargo transport essential for barrier integrity and pathogen sensing.

Purpose of the Study:

  • To review mechanisms pathogens use to disrupt RAB11 pathways.
  • To highlight RAB11's role in host-pathogen interactions.

Main Methods:

  • Literature review of pathogen strategies targeting RAB11.
  • Analysis of RAB11's function in vesicular transport and immunity.

Main Results:

  • Pathogens have evolved diverse strategies to interfere with RAB11-dependent vesicular trafficking.
  • Disruption of RAB11 pathways compromises host defense mechanisms.

Conclusions:

  • Targeting RAB11 is a common strategy for bacterial and viral pathogens.
  • Understanding these interactions is key to developing new anti-infective therapies.
