Peripheral interleukin-1ß levels are elevated in chronic tension-type headache patients

|August 20, 2013
Summary
Elevated levels of interleukin (IL)-1β and IL-18 are linked to chronic tension-type headache (CTTH). This suggests sterile neurovascular inflammation, not genetic factors, may drive CTTH pathology.
Area of Science:
- Neuroscience
- Immunology
- Genetics
Background:
- Chronic tension-type headache (CTTH) is a prevalent and challenging condition.
- Its exact causes are unclear, but likely multifactorial.
- Immunomodulatory cytokines are implicated in chronic pain disorders like CTTH.
Purpose of the Study:
- To investigate the involvement of peripheral cytokines and genetic factors in CTTH development.
- To identify common pathological mechanisms in CTTH.
Main Methods:
- Cytometric bead arrays and ELISAs were used to measure cytokine levels in 56 CTTH patients and 42 controls.
- Polymerase chain reaction and restriction fragment length polymorphism analyzed genetic variations in the IL-1B gene.
Main Results:
- Significantly elevated levels of interleukin (IL)-1β were observed in CTTH patients compared to controls.
- IL-18 levels were notably higher in men with CTTH.
- No genetic association was found between CTTH and single nucleotide polymorphisms in the IL-1β gene.
Conclusions:
- Increased levels of proinflammatory cytokines are associated with CTTH.
- The findings point towards sterile neurovascular inflammation as a key component in CTTH pathology.

Acute Inflammation II: Local and Systemic Effects
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
