Summary
Pathogen engulfment creates special phagosomes coated with LC3/Atg8 for sustained antigen presentation. This LC3-associated phagocytosis impacts immune responses.
Area of Science:
- Immunology
- Cell Biology
- Molecular Biology
Background:
- Phagosomes are crucial for pathogen clearance and antigen presentation.
- Autophagy machinery components, like LC3/Atg8, are involved in various cellular processes.
- Specific phagosome subsets have unique roles in antigen preservation.
Purpose of the Study:
- To discuss the outcomes of LC3-associated phagocytosis.
- To explore the immunological implications of LC3-coated phagosomes.
Main Methods:
- Analysis of phagosome formation and antigen presentation.
- Investigation of LC3/Atg8 coating on phagosomes.
- Review of existing literature on autophagy and immunology.
Main Results:
- A subset of phagosomes preserves antigens for extended MHC class II presentation.
- These phagosomes are characterized by LC3/Atg8 coating.
- LC3-associated phagocytosis represents a distinct pathway.
Conclusions:
- LC3-associated phagocytosis plays a significant role in adaptive immunity.
- Understanding this pathway can reveal new therapeutic targets.
- This mechanism enhances the longevity of antigen presentation for immune memory.

64.7K
Cells pull particles inward and engulf them in spherical vesicles in an energy-requiring process called endocytosis. Phagocytosis (“cellular eating”) is one of three major types of endocytosis. Cells use phagocytosis to take in large objects—such as other cells (or their debris), bacteria, and even viruses.

01:17Phagocytosis of Apoptotic Cells
3.9K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.

01:36Delivery Pathways to the Lysosome
7.6K
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.

01:25Immune Surveillance by NK Cells and Phagocytes
7.2K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

10.6K
Eukaryotic cells acquire nutrients for growth and proliferation. Nutrients and other molecules that require degradation are internalized from the extracellular space by a process called endocytosis. The term ‘endocytosis' was first coined by Christian de Duve in 1963.
Endocytosis always begins with the plasma membrane enclosing an incoming molecule to form a transport vesicle which, in some cases, can be coated with a protein called ‘clathrin.' Endocytosed material is either...
