Summary
Kinins, such as bradykinin, may play a role in asthma. This study explored how these peptides affect asthmatic airways, suggesting a complex interaction involving multiple receptor types.
Area of Science:
- Pharmacology
- Respiratory Medicine
- Molecular Biology
Background:
- Bradykinin and related peptides are implicated as mediators in bronchial asthma.
- These oligopeptides interact with specific cell surface receptors.
- Understanding kinin activity in the airways is crucial for asthma research.
Purpose of the Study:
- To investigate the structure-activity relationship of kinins in the lower airways of asthmatic subjects.
- To elucidate the role of kinins as potential mediators in asthma pathogenesis.
- To identify the specific receptor interactions involved in kinin effects on asthmatic airways.
Main Methods:
- Study conducted on 16 subjects with bronchial asthma.
- Investigated the effects of bradykinin, kallidin, and [desArg9]-bradykinin.
- Focused on structure-activity relationships within the lower airways.
Main Results:
- Kinins exhibit a complex action on asthmatic airways.
- Evidence suggests the involvement of more than one receptor subtype.
- Specific interactions of kinins were observed in the lower airways.
Conclusions:
- Kinins are likely complex mediators in the pathogenesis of bronchial asthma.
- Multiple kinin receptor subtypes may be involved in asthmatic airway responses.
- Further research is warranted to fully characterize kinin receptor interactions in asthma.

01:25Cholinergic Receptors: Muscarinic
The pharmacological actions of acetylcholine are elicited via its binding to two families of cholinergic receptors or cholinoceptors, namely, muscarinic and nicotinic receptors. Muscarinic receptors are G protein-coupled receptors and have five subtypes, M1–M5. All mAChR subtypes are activated by acetylcholine and blocked by the antagonist, atropine.
The subtypes M1, M3, and M5 couple with the Gq subunit and activate the phospholipase C (PLC) activity, mobilizing intracellular Ca2+. Activation...

01:27Adrenergic Receptors (Adrenoceptors): Classification
Adrenergic receptors, or adrenoceptors, respond to the autonomic neurotransmitter noradrenaline and other endogenous catecholamine agonists. They are classified into two main families, α and β, based on their pharmacological response and are further subdivided depending on their location, elicited response, and affinity to specific agonists or antagonists.

α-Adrenoceptors are classified into two main subtypes: α1 and α2. The α1 adrenoceptors, which are found on postsynaptic...

01:31Adrenergic Receptors: ɑ Subtype
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase C—inositol-1,4,5-trisphosphate...

01:26Adrenergic Receptors: β Subtype
β-adrenoceptors have varied sensitivities towards adrenaline, noradrenaline, and isoprenaline. The order of agonist potency is as follows:
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
β1-adrenoceptors: β1-adrenoceptors have equal affinities for...

01:28Antihypertensive Drugs: Types of β-Blockers
β receptors are classified into three subclasses: β1, β2, and β3. β1 receptors are primarily located in the heart and kidneys. When they get activated, they increase heart rate, contractility, and renin release. This process enhances blood pressure and aids in stress management. In contrast, β2 receptors are situated mainly in the lungs, blood vessels, and skeletal muscles. Upon activation, they trigger smooth muscle relaxation, causing bronchodilation and vasodilation. This widens airways and...
01:20Antiasthma Drugs: Muscarinic Receptor Antagonists
Muscarinic receptor antagonists, also known as antimuscarinic agents, are a class of bronchodilators used to treat asthma, although they are more commonly used to treat COPD. They work by inhibiting the action of acetylcholine (ACh), a neurotransmitter, on muscarinic receptors found in the airways.
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...
