Histamine 2/3 receptor agonists alleviate perioperative neurocognitive disorders by inhibiting microglia activation through the PI3K/AKT/FoxO1 pathway in aged rats

Journal of Neuroinflammation, 2020
Background Microglia, the principal sentinel immune cells of the central nervous system (CNS), play an extensively vital role in neuroinflammation and perioperative neurocognitive disorders (PND).

Role of Histamine and Related Signaling in Kaposi’s Sarcoma-Associated Herpesvirus Pathogenesis and Oncogenesis

Viruses, 2023
Although Kaposi’s sarcoma-associated herpesvirus (KSHV) has been reported to cause several human cancers including Kaposi’s sarcoma (KS) and primary effusion lymphoma (PEL), the mechanisms of KSHV-induced tumorigenesis, especially virus–host interaction ...

Histamine 2 Receptor Agonism and Histamine 4 Receptor Antagonism Ameliorate Inflammation in a Model of Psoriasis

Acta Dermato-Venereologica, 2020
Psoriasis is a chronic inflammatory skin disorder characterized by hyperproliferative keratinocytes and immune cell infiltration into the skin, often accompanied by itch.

Votucalis, a Novel Centrally Sparing Histamine-Binding Protein, Attenuates Histaminergic Itch and Neuropathic Pain in Mice

Frontiers in Pharmacology, 2022
Votucalis is a biologically active protein in tick (R. appendiculatus) saliva, which specifically binds histamine with high affinity and, therefore, has the potential to inhibit the host’s immunological responses at the feeding site. We hypothesized that

Recent Advances in Molecular Pharmacology of the Histamine Systems: Roles of C-terminal Tails of Histamine Receptors

Journal of Pharmacological Sciences, 2006
.: G-protein-coupled receptors (GPCR) represent a large and diverse superfamily of integral membrane proteins to which histamine receptors belong. Increasing numbers of proteins have been identified to interact with the C-termini of GPCRs.

Effects of histamine on human periodontal ligament fibroblasts under simulated orthodontic pressure.

PLoS ONE, 2020
As type-I-allergies show an increasing prevalence in the general populace, orthodontic patients may also be affected by histamine release during treatment.

Structural insights into the agonists binding and receptor selectivity of human histamine H4 receptor

Nature Communications, 2023
Histamine is a biogenic amine that participates in allergic and inflammatory processes by stimulating histamine receptors. The histamine H4 receptor (H4R) is a potential therapeutic target for chronic inflammatory diseases such as asthma and atopic ...

Histamine elicits glutamate release from cultured astrocytes

Journal of Pharmacological Sciences, 2018
Astrocytes play key roles in regulating brain homeostasis and neuronal activity. This is, in part, accomplished by the ability of neurotransmitters in the synaptic cleft to bind astrocyte membrane receptors, activating signalling cascades that regulate ...

Increased Sensitivity of Mice Lacking Extrasynaptic δ-Containing GABAA Receptors to Histamine Receptor 3 Antagonists

Frontiers in Pharmacology, 2020
Histamine/gamma-aminobutyric acid (GABA) neurons of posterior hypothalamus send wide projections to many brain areas and participate in stabilizing the wake state.

Histamine Produced by Gram-Negative Bacteria Impairs Neutrophil’s Antimicrobial Response by Engaging the Histamine 2 Receptor

Journal of Innate Immunity, 2022
We found that histamine (10−9 M) did not have any effect on the in vitro capture of Escherichia coli by neutrophils but accelerated its intracellular killing.
