  2. Histamine - Wikipedia

    en.wikipedia.org/wiki/Histamine

    Histamine is an organic nitrogenous compound involved in local immune responses communication, as well as regulating physiological functions in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus.

  3. Histamine intolerance - Wikipedia

    en.wikipedia.org/wiki/Histamine_intolerance

    Histamine intolerance is a presumed set of adverse reactions (such as flush, itching, rhinitis, etc.) to ingested histamine in food. The mainstream theory accepts that there may exist adverse reactions to ingested histamine, but does not recognize histamine intolerance as a separate medical condition that can be diagnosed. [1]

  4. Mast cell activation syndrome - Wikipedia

    en.wikipedia.org/wiki/Mast_cell_activation_syndrome

    Mast cell activation syndrome (MCAS) is a term referring to one of two types of mast cell activation disorder (MCAD); the other type is idiopathic MCAD. [1] MCAS is an immunological condition in which mast cells, a type of white blood cell, inappropriately and excessively release chemical mediators, such as histamine, resulting in a range of chronic symptoms, sometimes including anaphylaxis or ...

  5. Mast cell - Wikipedia

    en.wikipedia.org/wiki/Mast_cell

    Mast cells serve the same general functions in the body and central nervous system, such as effecting or regulating allergic responses, innate and adaptive immunity, autoimmunity, and inflammation. [4] [18] Across systems, mast cells serve as the main effector cell through which pathogens can affect the gut–brain axis. [19] [20]

  6. Hypersensitivity - Wikipedia

    en.wikipedia.org/wiki/Hypersensitivity

    Type IV hypersensitivity reactions are, to some extent, normal physiological events that help fight infections, and dysfunction in this system can predispose to multiple opportunistic infections. Adverse events can also occur due to these reactions when an undesirable interaction between the immune system and an allergen happens. [9]

  7. Histidine decarboxylase - Wikipedia

    en.wikipedia.org/wiki/Histidine_decarboxylase

    Histamine is an important biogenic amine that moderates numerous physiologic processes. There are four different histamine receptors, H 1, H 2, H 3, and H 4, [16] each of which carries a different biological significance. H 1 modulates several functions of the central and peripheral nervous system, including circadian rhythm, body temperature ...

  8. Histaminergic - Wikipedia

    en.wikipedia.org/wiki/Histaminergic

    Histaminergic means "working on the histamine system", and histaminic means "related to histamine". [1] A histaminergic agent (or drug) is a chemical which functions to directly modulate the histamine system in the body or brain. Examples include histamine receptor agonists and histamine receptor antagonists (or antihistamines).

  9. Histamine receptor - Wikipedia

    en.wikipedia.org/wiki/Histamine_receptor

    [1] [2] Histamine is a neurotransmitter involved in various physiological processes. There are four main types of histamine receptors: H1, H2, H3, and H4. H1 receptors are linked to allergic responses, H2 to gastric acid regulation, H3 to neurotransmitter release modulation, and H4 to immune system function. There are four known histamine ...
