Insights

Phosphoinositides are crucial for innate immune cells to engulf and kill microbes. Pathogens can disrupt phosphoinositide metabolism to survive inside host cells.

Area of Science:

  • Immunology
  • Cell Biology
  • Microbiology

Background:

  • Innate immune cells engulf microbes via phagosomes.
  • Phagosome maturation is essential for microbial killing.
  • Pathogens can evade killing by interfering with phagosome maturation.

Purpose of the Study:

  • To provide an overview of phosphoinositides in immune cells.
  • To discuss phosphoinositide metabolism during phagocytosis and maturation.
  • To explore how pathogens alter phosphoinositides to survive intracellularly.

Main Methods:

  • Review of existing literature on phosphoinositides and phagocytosis.
  • Analysis of phosphoinositide roles in immune cell function.
  • Examination of pathogen strategies impacting phagosome maturation.

Main Results:

  • Phosphoinositides play a key role in phagosome formation and maturation.
  • Alterations in phosphoinositide metabolism are linked to pathogen survival.
  • Specific pathogens can manipulate phosphoinositide pathways.

Conclusions:

  • Phosphoinositides are critical regulators of innate immunity and phagosome function.
  • Understanding phosphoinositide derangements offers insights into infectious diseases.
  • Targeting phosphoinositide metabolism may present therapeutic strategies.

Phosphoinositides and PIPs01:42

Phosphoinositides and PIPs

Phosphoinositides are a group of phospholipids containing a glycerol backbone with two fatty acid chains and a phosphate attached to a myoinositol sugar ring. The inositol head group extends into the cytoplasm, where it is modified by adding phosphate groups to form phosphatidylinositol phosphates or PIPs.
Different phosphoinositides are synthesized and recruited on the cytosolic face of the plasma membrane. The localization of specific phosphoinositides concentrated in separate membrane...
IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the  phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and produces two-second...
Maturation of Endosomes01:28

Maturation of Endosomes

The early endosome containing internalized molecules matures through transformations in its location, morphology, intraluminal pH, and membrane protein composition. Together, these changes result in a more acidic late endosome that contains multiple intraluminal vesicles; therefore, the late endosome is also called a multivesicular body (MVB).
Changes in location
The maturing endosome moves along microtubules from the periphery of the cell towards the perinuclear region. This movement of the...
Phagocytosis00:41

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...

Intralumenal Vesicles and Multivesicular Bodies01:38

Intralumenal Vesicles and Multivesicular Bodies

Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...
