Insights

Neutrophils engulf pathogens into phagosomes, which mature into degradative vacuoles. This chapter details the molecular mechanisms of phagosome formation and maturation in neutrophils.

Area of Science:

  • Immunology
  • Cell Biology

Background:

  • Phagocytosis by neutrophils is crucial for eliminating pathogens.
  • Engulfed pathogens reside in phagosomes, vacuoles derived from the plasma membrane.
  • Phagosome maturation confers degradative capacity, essential for microbicidal function.

Purpose of the Study:

  • To review current knowledge on the molecular mechanisms of phagosome formation.
  • To discuss the molecular mechanisms governing phagosome maturation in neutrophils.

Main Methods:

  • Literature review of molecular mechanisms.
  • Analysis of current research on neutrophil phagocytosis.

Main Results:

  • Phagosome formation involves engulfment of pathogens.
  • Phagosome maturation is a complex process acquiring degradative properties.
  • Molecular pathways governing these processes are under investigation.

Conclusions:

  • Understanding phagosome formation and maturation is key to neutrophil microbicidal function.
  • Further research into the molecular details will elucidate neutrophil-mediated immunity.

Phagocytosis

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.The objective of phagocytosis is often destruction. Cells use phagocytosis to eliminate unwelcome visitors, like pathogens (e.g., viruses and bacteria). It is perhaps unsurprising, that many...

Immune Surveillance by NK Cells and Phagocytes01:25

Immune Surveillance by NK Cells and Phagocytes

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.

Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

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. 
Normal cells contain receptors that prevent them from being recognized by phagocytes.
Cells of the Innate Immune Response01:28

Cells of the Innate Immune Response

The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

Delivery Pathways to the Lysosome

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.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...
