Description
Neutrophils are the most abundant leukocytes and serve as first responders to infection and injury. Their migration to inflamed tissues is tightly controlled to ensure effective pathogen clearance while minimizing collateral damage. Negative regulation of neutrophil migration (GO:1902623) encompasses the molecular and cellular processes that restrain or terminate neutrophil movement, thereby resolving inflammation and maintaining tissue homeostasis. Dysregulation of this process is implicated in a spectrum of diseases, including sepsis, asthma, and chronic inflammatory disorders. Understanding the mechanisms that negatively regulate neutrophil migration is therefore of paramount importance for developing targeted anti-inflammatory therapies. This article synthesizes current knowledge from authoritative QuickGO annotations and peer-reviewed literature to provide a comprehensive overview of the genes, functions, and research methodologies associated with GO:1902623.

What Is GO:1902623?
GO:1902623, negative regulation of neutrophil migration, is defined as any process that stops, prevents, or reduces the frequency, rate, or extent of neutrophil migration. This biological process ensures that neutrophil recruitment is appropriately dampened to avoid excessive tissue damage and to promote the resolution of inflammation.
Why Is negative regulation of neutrophil migration Important in Cell Biology?
Negative regulation of neutrophil migration is critical for balancing effective host defense with tissue protection. Unchecked neutrophil infiltration can lead to severe tissue injury, as seen in acute respiratory distress syndrome and sepsis. Conversely, impaired negative regulation may contribute to chronic inflammatory conditions such as asthma and autoimmune disorders. Elucidating the molecular mechanisms of this process provides insights into disease pathogenesis and identifies potential therapeutic targets for modulating inflammation.
• Prevents excessive tissue damage during inflammation by limiting neutrophil recruitment.
• Promotes resolution of inflammation and return to homeostasis.
• Dysregulation is linked to sepsis severity and poor outcomes.
• Plays a role in asthma pathogenesis by controlling airway neutrophilia.
• Involved in wound healing through keratinocyte-autophagy-mediated regulation.
• Modulated by platelet-derived extracellular vesicles, linking thrombosis and inflammation.
• CCRL2 acts as a decoy receptor to fine-tune leukocyte migration.

What Happens During negative regulation of neutrophil migration?
Initiation of negative regulation
In simple terms: The body starts to put the brakes on neutrophil movement.
Negative regulation of neutrophil migration is initiated by signals that counteract chemoattractants. For example, activation of CD44 on epithelial cells can suppress neutrophil transepithelial migration. Similarly, DEL-1 acts as an anti-neutrophil transepithelial migration molecule in airway inflammation. These cues trigger intracellular pathways that reduce the frequency and rate of neutrophil migration.
Molecular brakes on chemotaxis
In simple terms: Specific molecules interfere with the signals that tell neutrophils to move.
Chemokine receptors and their decoys play a central role. CCRL2, a non-signaling receptor, binds chemokines and prevents their interaction with signaling receptors, thereby dampening leukocyte migration. Additionally, negative regulation of immune signaling pathways in neutrophils, such as those involving CD44, can inhibit migratory responses.
Cell-cell interactions and extracellular vesicles
In simple terms: Other cells and tiny particles can tell neutrophils to slow down.
Platelet-derived extracellular vesicles transfer mitochondria to neutrophils, modulating their phenotype and function, which can include reduced migration. In sepsis, B-1a cells interact with neutrophils via Siglec-G, influencing neutrophil homeostasis and migration. These interactions highlight the complex intercellular communication that negatively regulates neutrophil migration.
Resolution and tissue repair
In simple terms: The brakes help inflammation end and tissues heal.
Keratinocyte autophagy facilitates wound healing by activating keratinocytes and fibroblasts, which may indirectly limit neutrophil infiltration. The resolution phase involves active suppression of neutrophil recruitment, allowing macrophages to clear debris and promote tissue repair. Negative regulation of neutrophil migration is thus integral to the transition from inflammation to healing.

How Is negative regulation of neutrophil migration Regulated?
Negative regulation of neutrophil migration is controlled by a network of signaling pathways, including those involving mTOR, PI3K, and immune checkpoint molecules. For instance, activation of CD44 triggers intracellular signals that inhibit neutrophil transepithelial migration. DEL-1 acts as an anti-neutrophil molecule in asthma, and its expression is regulated by inflammatory cues. CCRL2 functions as a decoy receptor to modulate chemokine gradients. In sepsis, the heterogeneity of patients affects the regulation of neutrophil migration, with factors such as Siglec-G playing a role. Additionally, platelet-derived extracellular vesicles can transfer mitochondria to neutrophils, altering their migratory capacity. These regulatory mechanisms ensure that neutrophil recruitment is appropriately dampened to prevent tissue damage.
negative regulation of neutrophil migration and Human Disease
| Gene | Disease / Biology | Potential Experimental Model |
|---|---|---|
| DEL-1 | Asthma | Knockout mouse model of allergic airway inflammation |
| Siglec-G | Sepsis | B-1a cell-specific knockout mice |
| CD44 | Inflammatory bowel disease | Intestinal epithelial cell-specific knockout |
| CCRL2 | Rheumatoid arthritis | CCRL2 knockout mice |
| PTPN22 | Autoimmune diseases | PTPN22 knock-in mice |
Sepsis
In sepsis, dysregulated neutrophil migration contributes to organ damage. Negative regulation is often impaired, leading to excessive neutrophil infiltration. Siglec-G on B-1a cells has been shown to exacerbate sepsis by disrupting neutrophil homeostasis. The complexity of molecular mechanisms and patient heterogeneity further complicates the regulation of neutrophil migration in sepsis.
Asthma
Airway neutrophilic inflammation in asthma is associated with severe disease. DEL-1, an anti-neutrophil transepithelial migration molecule, inhibits this process and is a potential therapeutic target. Negative regulation of neutrophil migration is thus crucial for controlling asthma exacerbations.
Wound Healing and Chronic Inflammation
Keratinocyte autophagy facilitates wound healing by activating keratinocytes and fibroblasts, which may limit neutrophil infiltration. Impaired negative regulation can lead to chronic inflammation and delayed healing, as seen in diabetic ulcers and autoimmune diseases.
