The Physiology and Pathophysiology of CGRP
Calcitonin gene-related peptide is encoded by the CALCA and CALCB genes, resulting in two primary isoforms: alpha-CGRP (α-CGRP) and beta-CGRP (β-CGRP). This peptide is synthesized through the alternative RNA splicing of the calcitonin gene, a process that dictates its specific form based on tissue. CGRP is widely distributed throughout the human body, appearing in sensory and motor neurons, as well as in various organs and tissues.
One of the most well-established functions of CGRP is its role as a potent vasodilator. When released from sensory nerves, calcitonin gene-related peptide induces vasodilation, meaning it causes blood vessels to widenCGRP is a 37 amino acid residue peptidederived from the alternative splicing, in a tissue specific manner, of the calcitonin gene and may exist in two forms α .... This effect is mediated through its interaction with the calcitonin gene-related peptide receptor, a complex composed of CALCRL (also known as CLR) and RAMP1.Calcitonin Gene Related Peptide, CGRP (alpha), human While CGRP is a potent vasodilator, research indicates that it does not directly regulate blood pressure or overall hemodynamics in a significant manner under normal physiological conditions. However, its vasodilatory capacity becomes critically important in certain pathological states, such as migraines.作者:JC Ray·2021·被引用次数:73—After 30 years of translational research,calcitonin gene-related peptide (CGRP) inhibitorshave emerged as a promising new tool in the prevention of migraine.
Beyond vasodilation, CGRP is implicated in several other physiological processes, including:
* Neurogenic Inflammation: CGRP contributes to inflammation by triggering the release of inflammatory mediators from nerve endings.
* Central and Peripheral Sensitization: It plays a role in the sensitization of the nervous system, which can lead to heightened pain perception.Calcitonin Gene Related Peptide (CGRP), rat
* Cardiovascular Regulation: While not its primary role in blood pressure, CGRP has been observed to have effects on the heart, though this area has received less attention compared to its role in migraine.
* Other Functions: Emerging research suggests CGRP may also be involved in processes like bone metabolism and pancreatic beta-cell function.Calcitonin Gene Related Peptide (rat) is a potent, long-lasting vasodilator; activation of CGRP receptors on pancreatic β-cells increases plasma levels of ...
CGRP and Migraine: A Deep Connection
The link between calcitonin gene-related peptide and migraines is one of the most significant findings in headache research. It is now widely accepted that CGRP plays a crucial role in the pathophysiology of migraine attacks. During a migraine, CGRP is released from trigeminal nerves, which are sensory nerves located in the head. This release leads to several key events:
* Cerebral Vessel Vasodilation: The potent vasodilatory action of CGRP causes blood vessels in the brain's coverings (meninges) to dilate, contributing to the throbbing pain characteristic of migraines.
* Neurogenic Inflammation: CGRP promotes inflammation in the meninges, further exacerbating the pain and discomfort.
* Nervous System Sensitization: It contributes to the sensitization of the nervous system, making individuals more susceptible to pain signals.

While primarily recognized as a .... While published data on calcitonin gene-related peptide concentrations in human plasma can sometimes be inconsistent, the overall evidence strongly supports its involvement in migraine pathogenesis. CGRP's release and subsequent actions are considered a central mechanism driving the pain and associated symptoms of migraine.
Therapeutic Targeting of CGRP
The profound understanding of CGRP's role in migraine has revolutionized treatment strategies. Two main classes of drugs have emerged that target the calcitonin gene-related peptide pathway:
1作者:A Bonura·2023·被引用次数:23—Thecalcitonin gene-related peptide (CGRP) is a neuropeptide widely distributed throughout the human body. While primarily recognized as a .... CGRP Inhibitors (Gepants): These are a newer class of medications that act as calcitonin gene-related peptide receptor antagonists.Calcitonin gene-related peptide (CGRP) is defined as a neuropeptide encoded by the CALCA and CALCB genes, resulting in two forms, α-CGRP and β-CGRP, ... Commonly known as gepants, these drugs block the binding of CGRP to its receptor, thereby preventing its downstream effects like vasodilation and inflammation. Calcitonin gene-related peptide receptor antagonists are indicated for the acute treatment of migraine with or without aura and have provided significant relief for many patients who did not respond to traditional treatments. Some calcitonin gene-related peptide (CGRP) inhibitors are also being explored for migraine prevention.
2. CGRP Monoclonal Antibodies (CGRP mAbs): These are biologic therapies that target and block CGRP itself or its receptor. CGRP monoclonal antibodies are designed for the preventive treatment of migraines. By neutralizing CGRP, these antibodies reduce the frequency and severity of migraine attacks. Calcitonin gene-related peptide (CGRP) monoclonal antibodies represent a major advancement in migraine management, offering a targeted approach to this debilitating condition.Calcitonin Gene-Related Peptide (CGRP) Inhibitors
