Disorders of phagocyte chemotaxis
Annals of Internal Medicine
|April 1, 1980
Summary
Patients with recurrent infections due to abnormal phagocyte chemotaxis are being identified. Understanding these defects offers new treatment strategies for immune system disorders.
Area of Science:
- Immunology
- Cell Biology
- Clinical Medicine
Background:
- Recurrent infections can stem from impaired phagocyte chemotaxis.
- Phagocyte recruitment to inflammatory sites is crucial for immune response.
Purpose of the Study:
- To identify and characterize defects in phagocyte chemotaxis.
- To explore potential therapeutic strategies for patients with phagocyte dysfunction.
Main Methods:
- Functional, biochemical, and ultrastructural analysis of phagocyte function.
- Assessment of chemoattractant mediator production and regulation.
- Evaluation of circulating phagocyte subpopulations.
Main Results:
- Identified patients with abnormalities in phagocyte chemotaxis.
- Distinguished between defects in chemoattractant production/regulation and phagocytic cell function.
- Characterized cellular defects as intrinsic or acquired.
Conclusions:
- Understanding phagocyte chemotaxis defects is key to diagnosing and treating recurrent infections.
- Rational therapeutic approaches are being developed based on characterized defects.
- Clinical trials are evaluating pharmacologic interventions for phagocyte chemotaxis disorders.

00:41Phagocytosis
6.9K
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,...

01:21Chemotaxis and Direction of Cell Migration
5.0K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

01:27Disorders of Leukocytes
2.3K
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

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.

1.4K
Chemotaxis in Escherichia coli is a sensory-driven motility mechanism that enables bacteria to navigate chemical gradients, moving toward beneficial environments while avoiding harmful conditions. This process relies on a signal transduction system integrating external chemical cues with flagellar motor control.Chemoreceptors and Signal DetectionE. coli detects chemical gradients through methyl-accepting chemotaxis proteins (MCPs), which are membrane-bound chemoreceptors that sense attractants...

01:26Acute Inflammation I: Cellular Phase
82
The cellular phase of acute inflammation is a tightly orchestrated sequence of events that recruits leukocytes, primarily neutrophils, to sites of tissue injury or infection. Following the initial vascular changes, this phase ensures effective immune cell migration, activation, and function at the affected site to eliminate pathogens and initiate tissue repair.Leukocyte Recruitment CascadeLeukocyte recruitment happens in four steps: margination, adhesion, transmigration, and chemotaxis. Reduced...
