  1. 1. Muscarinic acetylcholine receptors : investigation of interactions with agonists and antagonists

    Author : Britta Hedlund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In the present investigation interactions of agonists and antagonists with the muscarinic acetylcholine receptor from rat cerebral cortex and rat ileum smooth muscle have been characterized.It is suggested that the binding of antagonist involves two sequential equilibria, an association reaction followed by isomerization of the receptor-antagonist complex.

  2. 2. Acetylcholine in Spinal Pain Modulation : An in vivo Study in the Rat

    Author : Klas Abelson; Urban Höglund; Ernst Brodin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Laboratory animals; Pain; Nociception; Antinociception; Acetylcholine; Muscarinic; Nicotinic; Spinal cord; Microdialysis; Försöksdjursvetenskap; Laboratory animal science; Försöksdjursvetenskap;

    Abstract : The spinal cord is an important component in the processing and modulation of painful stimuli. Nerve signals from the periphery are relayed and further conducted to the brain (nociception) in the spinal cord, and the most essential modulation of painful information (antinociception) occurs here.

  3. 3. Spinal Acetylcholine Release : Mechanisms and Receptor Involvement

    Author : Mahinda Kommalage; Urban Höglund; Ernst Brodin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; acetylcholine release; spinal antinociception; nicotinic receptor; serotonin; GABA; Neurovetenskap; Neurology; Neurologi;

    Abstract : Impulses coming from peripheries are modified in the spinal cord and transmitted to the brain. Several neurotransmitters have been involved in the processing of impulses in the spinal dorsal horn. Acetylcholine (ACh) is one of many neurotransmitters involved in the regulation of nociception in the spinal cord. READ MORE

  5. 5. Muscarinic receptors and urinary bladder selectivity : Properties that determine the organ selectivity of compounds

    Author : Staffan Sundquist; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; bladder; muscarinic; receptor subtypes; smooth muscle; multivariate; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Urinary bladder contraction is mainly mediated by activation of muscarinic acetylcholine receptors (mAChR). Muscarinic antagonists are often effective in treatment of unstable bladder. The effectiveness of this treatment has often been limited by side effects as dry mouth. READ MORE
