Spinal neurons that contain gastrin-releasing peptide seldom express Fos or phosphorylate extracellular signal-regulated kinases in response to intradermal chloroquine [PDF]

, 2016
Background: Gastrin-releasing peptide (GRP) is thought to play a role in the itch evoked by intradermal injection of chloroquine. Although some early studies suggested that GRP was expressed in pruriceptive primary afferents, it is now thought that GRP ...

HISTAMINE H3 RECEPTOR INVERSE AGONISTS ON COGNITIVE AND MOTOR PROCESSES: RELEVANCE TO ALZHEIMER’S DISEASE, ADHD, SCHIZOPHRENIA AND DRUG ABUSE

Frontiers in Systems Neuroscience, 2012
Histamine H3 receptor antagonists/ inverse agonists possess potential to treat diverse disease states of the central nervous system (CNS). Cognitive dysfunction and motor impairments are the hallmark of multifarious neurodegenerative and/or psychiatric ...

THE EFFECTS OF HISTAMINE AND SOME HISTAMINE‐LIKE AGONISTS ON BLOOD PRESSURE IN THE CAT [PDF]

British Journal of Pharmacology, 1975
The effects of histamine on blood pressure have been compared with the effects caused by four histamine‐like agonists in anaesthetized cats. It has been confirmed that the depressor responses to histamine involve both H1‐ and H2‐receptors: depressor responses also follow the administration of selective H1‐ and H2 ‐receptor agonists. 2‐Methylhistamine,

Role of protein phosphatases inhibitors on the histamine release and the functional desensitization in human lung mast cells

Journal of Research in Medical Sciences, 2014
Background: The β2-adrenoceptor agonist, isoprenaline, is an effective inhibitor of histamine release from human lung mast cells (HLMC). Since phosphorylations of the β2-adrenoceptors are probably important in inducing desensitization, we sought to ...

Antihistamines for the treatment of urticaria in Mexico

Revista Alergia México, 2015
There are four types of histamine receptors. Allergic symptoms, especially those in rhinoconjunctivitis and urticaria, are mainly caused by activation of histamine receptor 1 (H1).

Antihistamines suppress upregulation of histidine decarboxylase gene expression with potencies different from their binding affinities for histamine H1 receptor in toluene 2,4-diisocyanate-sensitized rats

Journal of Pharmacological Sciences, 2016
Antihistamines inhibit histamine signaling by blocking histamine H1 receptor (H1R) or suppressing H1R signaling as inverse agonists. The H1R gene is upregulated in patients with pollinosis, and its expression level is correlated with the severity of ...

Theophylline

, 2010
Theophylline (3-methyxanthine) has been used to treat airway diseases for over 70 years. It was originally used as a bronchodilator but the relatively high doses required are associated with frequent side effects, so its use declined as inhaled β₂ ...

Bottom-Up versus Top-Down Induction of Sleep by Zolpidem Acting on Histaminergic and Neocortex Neurons [PDF]

, 2016
Zolpidem, a GABAA receptor-positive modulator, is the gold-standard drug for treating insomnia. Zolpidem prolongs IPSCs to decrease sleep latency and increase sleep time, effects that depend on α2 and/or α3 subunit-containing receptors.

Histaminergic Mechanisms for Modulation of Memory Systems

Neural Plasticity, 2011
Encoding for several memory types requires neural changes and the activity of distinct regions across the brain. These areas receive broad projections originating in nuclei located in the brainstem which are capable of modulating the activity of a ...
