Summary
Podosomes, F-actin-rich cell structures, are crucial for cell migration and matrix degradation. Emerging research highlights their role in immune cell phagocytosis, mechanosensing, and particle disruption.
Area of Science:
- Cell Biology
- Immunology
Background:
- Podosomes are micron-sized, F-actin-rich structures involved in cell migration, invasion, and extracellular matrix degradation.
- In monocytic cells, podosomes have additional roles including substrate rigidity sensing and cell-cell fusion.
Purpose of the Study:
- To compare cell models and experimental setups describing "phagocytic podosomes" in immune cells.
- To discuss the composition, architecture, and functions of these phagocytic podosomes.
Main Methods:
- Comparative analysis of existing literature and experimental data on phagocytic podosomes.
- Review of studies on macrophages, dendritic cells, and neutrophils.
Main Results:
- Podosome-like structures are increasingly implicated in phagocytosis by various immune cells.
- These structures may be involved in mechanosensing and particle disruption during phagocytosis.
Conclusions:
- "Phagocytic podosomes" represent a significant area of research in cell biology and immunology.
- Further investigation is needed to confirm their classification as bona fide podosomes and elucidate their precise functions.

6.4K
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). Many immune system cells,...

01:25Immune Surveillance by NK Cells and Phagocytes
1.5K
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.

2.3K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

01:36Delivery Pathways to the Lysosome
6.6K
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.

01:42Phosphoinositides and PIPs
8.6K
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...

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.
