TY - JOUR. T1 - Mechanism of bradykinin-induced histamine release from rat peritoneal mast cells. AU - Zhao, Qiu E.. AU - Mihara, Takuma. AU - Sugimoto, Yukio. AU - Kamei, Chiaki. PY - 1996/2. Y1 - 1996/2. N2 - Bradykinin at concentrations higher than 2 μM caused a significant histamine release from rat peritoneal mast cells when extracellular Ca2+ was removed from the medium. Under the same experimental conditions, bradykinin increased Ca2+ release from the intracellular Ca store of the rat peritoneal mast cells, and a clear relationship was observed between the magnitude of histamine release and an increase in fluorescence intensity. Addition of Ca2+ to the medium resulted in an inhibition of the response to bradykinin in a concentration-dependent manner. Almost the same results were obtained when Mg2+, Ba2+ and La3+ were added to the medium. Neither B1 nor B2 antagonists caused significant antagonistic effects on histamine release induced by bradykinin. However, B2 antagonists caused a ...
TY - JOUR. T1 - Spontaneous histamine release and histamine content in normal subjects and subjects with asthma. AU - Akagi, Katsumi. AU - Townley, Robert G.. PY - 1989/4. Y1 - 1989/4. N2 - Spontaneous histamine release (SHR) from basophils by simple incubation at 37 °C for 60 minutes and histamine content of basophils were assessed in normal subjects, patients with asthma, and methacholine-sensitive subjects without asthma (NAMS). SHR from basophils of normal subjects did not exceed 10% of the total histamine. A significantly higher SHR was observed in basophils from subjects with asthma than from normal subjects (p ,0.002). Basophil SHR in patients with asthma not receiving medication was significantly greater than that in patients with asthma receiving medication (p ,0.05). SHR from basophils in NAMS subjects was similar to that in normal subjects. SHR was highly dependent on temperature and Ca++ and Mg++ ions and appeared to be a slower event than anaphylactic release. The mean histamine ...
Basophils possess membrane bound IgE molecules, and immunological activation leads to a secretory process with cell degranulation and histamine release. Heterologous anti IgE, concanavaline A, and phytohaemagglutinin are potent non-cytotoxic releasing agents. They operate by a mechanism similar to that of immunological activation. Heavy water is not a histamine releasing inducer but it increases histamine release of the cells. We studied the histamine release reaction of leukaemic basophils in 10 patients and found a physiological response such as that previously reported with normal human basophils.. ...
Journal of Immunology Research is a peer-reviewed, Open Access journal that provides a platform for scientists and clinicians working in different areas of immunology and therapy. The journal publishes research articles, review articles, as well as clinical studies related to classical immunology, molecular immunology, clinical immunology, cancer immunology, transplantation immunology, immune pathology, immunodeficiency, autoimmune diseases, immune disorders, and immunotherapy.
Most histamine in the body is generated in granules in mast cells and in white blood cells called basophils andeosinophils. Mast cells are especially numerous at sites of potential injury -- the nose, mouth, and feet, internal body surfaces, and blood vessels. Non-mast cell histamine is found in several tissues, including the brain, where it functions as a neurotransmitter. Another important site of histamine storage and release is the enterochromaffin-like (ECL) cell of the stomach.. The most important pathophysiologic mechanism of mast cell and basophil histamine release is immunologic. These cells, if sensitized byIgE antibodies attached to their membranes, degranulate when exposed to the appropriate antigen. Certain amines and alkaloids, including such drugs as morphine, and curare alkaloids, can displace histamine in granules and cause its release. Antibiotics likepolymyxin are also found to stimulate histamine release.. Histamine release occurs when allergens bind to mast-cell-bound IgE ...

Methoctramine, a selective M2 muscarinic cholinergic receptor antagonist, has been reported to activate phosphoinositide breakdown at high concentrations. Its polyamine structure suggests a putative activation of guanine nucleotide-binding proteins (G proteins). Incubation of methoctramine with rat peritoneal mast cells resulted in a dose-dependent noncytotoxic histamine release, with an EC50 of 20 microM and a maximum effect at 1 mM. Atropine, pirenzepine and HHSiD neither inhibited methoctramine-induced histamine release nor stimulated histamine release. Histamine release and inositol phosphates generation induced by methoctramine were both inhibited by pertussis toxin pretreatment. Benzalkonium chloride, a ...

The Translational Controlled Tumour Protein TCTP (gene symbol TPT1, also called P21, P23, Q23, fortilin or histamine-releasing factor, HRF) is a highly conserved protein present in essentially all eukaryotic organisms and involved in many fundamental cell biological and disease processes. It was first discovered about 35 years ago, and it took an extended period of time for its multiple functions to be revealed, and even today we do not yet fully understand all the details. Having witnessed most of this history, in this chapter, I give a brief overview and review the current knowledge on the structure, biological functions, disease involvements and cellular regulation of this protein ...

How Delivering Free Radical Therapy According to the Designed2Win Health Model Provided a Positive Outcome. Every now and then a FRT health provider may run into a client who presents a confusing situation that hadnt been solved with meds, and really cant get solved through FRT without returning to its health model basis. An example is a recent client who demonstrated an eosinophilic white blood count of more than 20%. Less than 4% is normal, so 20% is not healthy, especially when allowed to remain that high, as the amount of toxins released by eosinophils aimed at killing parasites but which can be stimulated by any allergen are certain to damage healthy tissues. Such a scenario affecting the lungs can cause severe compromise in lung function, leading to COPD, asthma or a tumor.. In this scenario the culprit is generally some allergen that has stimulated both the mast cells and the basophilic white blood cells to release histamine. The histamine helps stimulate bone marrow to produce more ...
There are seven types of white blood cells, two of which are primarily involved in the inflammation process. Eosinophils control allergic responses, while basophils release histamine during an inflammatory response ...
C3a is an anaphylatoxin that triggers a response by stimulating inflammatory cells to release histamine, enzymes, cytokines and other mediators.
How MRT Compares to IgG: There are a number of advantages of MRT over any form of IgG testing. MRT is an endpoint test, meaning that all the immune based adverse reactions that end up causing a mediator release in the blood will be identified. So MRT does this without caring about the mechanism (such as IgG). In fact MRT is able to take into account the actions of all mechanisms, whether they are antibodies or other, because all of them ultimately cause white blood cells to release mediators. MRT is able to account for a much wider array of reactions than the relatively simple IgG testing. In addition, MRT is able to identify reactions to chemicals. Overall MRT is more accurate an useful clinically.. The ALCAT Test: The ALCAT test was invented and patented by the same person who invented and patented MRT, Dr Mark Pasula. The two technologies are similar, yet separately patented, which means there is a unique difference. The main difference between the two tests is in terms of accuracy and ...

TY - JOUR. T1 - Effect of loratadine on histamine release induced by antigen-antibody reaction. AU - Kamei, Chiaki. AU - Sugimoto, Yukio. AU - Yamaji, Masako. AU - Takada, Miho. PY - 1996. Y1 - 1996. N2 - Loratadine caused an inhibition of histamine release from rat peritoneal mast culls induced by passively sensitized mast cells, and IC 50 was 9.57 μM. SCH 34117, a metabolite of loratadine, also inhibited histamine release from mast cells, and its potency was more than that of loratadine. Moreover, in ex vivo experiments, loratadine (5 mg/kg, p.o.) as well as terfenadine provided a relatively potent inhibitory effect on histamine release from lung pieces of actively sensitized guinea pigs exposed to antigen.. AB - Loratadine caused an inhibition of histamine release from rat peritoneal mast culls induced by passively sensitized mast cells, and IC 50 was 9.57 μM. SCH 34117, a metabolite of loratadine, also inhibited histamine release from mast cells, and its potency was more than that of ...
Latexin, a protein possessing inhibitory activity against rat carboxypeptidase A1 (CPA1) and CPA2, is expressed in a neuronal subset in the cerebral cortex and cells in other neural and non-neural tissues of rat. Although latexin also inhibits mast-cell CPA (MCCPA), the expression of latexin in rat mast cells has not previously been confirmed. In the present study we examined the expression and subcellular localization of latexin in rat peritoneal mast cells. Western blot and reverse-transcriptase-mediated PCR analyses showed that latexin was contained and expressed in the rat peritoneal mast cells. Immunocytochemically, latexin immunofluorescence was localized on granular structures distinct from MCCPA-, histamine- or cathepsin D-immunopositive granules. Immunoelectron microscopy revealed that latexin was associated with a minority population of granules. The latexin-associated granules were separated from MCCPA- or histamine-containing granules on a self-generating density gradient of ...
TY - JOUR. T1 - Inhibitory effect of nifedipine and cromolyn sodium on skin reactions and 45ca uptake and histamine release in rat mast cells induced by various stimulating agents. AU - Tanizaki, Yoshiro. AU - Akagi, Katsumi. AU - Lee, Kyung Nam. AU - Townley, Robert G.. PY - 1983. Y1 - 1983. N2 - The effect of nifedipine, one of the calcium channel antagonists, was examined in allergic and nonspecific reactions using rat skin and peritoneal mast cells. Rat passive cutaneous anaphylaxis response mediated by IgE antibody was inhibited by nifedipine (100 μg/rat) and also by cromolyn sodium (5 mg/rat). Skin reactions induced by histamine or methacholine were not inhibited, and skin reaction induced by serotonin was slightly inhibited by these drugs. The 45Ca uptake and histamine release in sensitized mast cells stimulated by ovalbumin were suppressed by nifedipine. In actively sensitized cells, nifedipine seems to be more effective on the inhibition of 45Ca uptake, but less effective on histamine ...
The mechanism of chronic mast cell activation in asthma is unclear. Monomeric immunoglobulin (Ig)E in the absence of allergen induces mediator release from rodent mast cells, indicating a possible role for IgE in the continued activation of mast cells within the asthmatic bronchial mucosa. In this study it was investigated whether monomeric IgE induces Ca2+ influx and mediator release from human lung mast cells (HLMC). Purified HLMC were cultured for 4 weeks and then exposed to monomeric human myeloma IgE. Ratiometric Ca2+ imaging was performed on single fura-2-loaded cells. Histamine release was measured by radioenzymatic assay; leukotriene C4 (LTC4) and interleukin (IL)-8 were measured by ELISA. At concentrations experienced in vivo, monomeric IgE induced dose-dependent histamine release, LTC4 production and IL-8 synthesis. This was associated with a rise in cytosolic free Ca2+. Enhanced histamine release was still evident 1 week after initial exposure to IgE suggesting that continued exposure ...
Human lung mast cells (HLMCs) play a central role in asthma pathogenesis through their relocation to the airway smooth muscle (ASM) bundles. β2 adrenoceptor (β2-AR)-agonists are used to relieve bronchoconstriction in asthma, but may reduce asthma control, particularly when used as monotherapy. We hypothesized that HLMC and human ASM cell (HASMC) responsiveness to β2-AR agonists would be attenuated when HLMCs are in contact with HASMCs. Cells were cultured in the presence of the short-acting β2-agonist albuterol, and the long-acting β2-agonists formoterol and olodaterol. Constitutive and FcεRI-dependent HLMC histamine release, HASMC contraction, and β2-AR phosphorylation at Tyr350 were assessed. Constitutive HLMC histamine release was increased in HLMC-HASMC coculture and this was enhanced by β2-AR agonists. Inhibition of FcεRI-dependent HLMC mediator release by β2-agonists was greatly reduced in HLMC-HASMC coculture. These effects were reversed by neutralization of stem cell factor ...
Cromone therapy is thought to inhibit IgE-dependent histamine release from mast cells, although the effects of sodium cromoglycate on human lung mast cells are weak. Both agents have weak effects on eosinophils and on macrophage activity but do not affect airway smooth muscle tone.
TY - JOUR. T1 - Comparative effect of recombinant IL-1, -2, -3, -4, and -6, IFN-γ, granulocyte-macrophage-colony-stimulating factor, tumor necrosis factor-α, and histamine-releasing factors on the secretion of histamine from basophils. AU - Alam, R.. AU - Welter, J. B.. AU - Forsythe, P. A.. AU - Lett-Brown, M. A.. AU - Grant, J. A.. PY - 1989. Y1 - 1989. N2 - Most cytokines possess multiple biologic activities. This study was undertaken to investigate the effect of rIL-1β, -2, -3, -4 and -6, IFN-γ, TNF-α, and granulocyte-macrophage (GM)-CSF on basophils from 16 donors and the amount of histamine releases was compared with that by partially purified mononuclear cell-derived histamine-releasing factor (HRF) and anti-IgE. We found that only IL-3 and GM-CSF at relatively high doses (50 to 500 ng/ml) released small amounts of histamine (3 to 14%) from two allergic donors. In contrast, both HRF and anti-IgE released significant amounts of histamine from all donors. Other cytokines did not ...
TY - JOUR. T1 - Cyclosporin A rapidly inhibits mediator release from human basophils presumably by interacting with cyclophilin. AU - Cirillo, Raffaele. AU - Triggiani, Massimo. AU - Siri, Lorenzo. AU - Ciccarelli, Anna. AU - Pettit, George. AU - Condorelli, Mario. AU - Marone, Gianni. PY - 1990. Y1 - 1990. N2 - We have examined the effects of cyclosporin A (CsA) and a series of CsA analogs that bind with decreasing affinity to cyclophilin, to evaluate the involvement of this protein in the release of preformed (histamine) and de novo synthesized (peptide leukotriene C4; LTC4) mediators of inflammatory reactions from human basophils. CsA (8 to 800 nM) concentration-dependently inhibited (5 to 60%) histamine release from peripheral blood basophils challenged with anti-IgE. CsA was more potent (92.6 ± 1.8 vs 59.1 ± 4.5%; p , 0.001) and, at low concentrations, more effective when the channel-operated influx of Ca2+ as bypassed by the ionophore A23187 (IC40 = 24.1 ± 3.9 vs 105.5 ± 22.2 nM; p , ...
The release mechanism of chemical mediators from basophils and mast cells was discussed when these cells were stimulated by different antigens and anti-IgE. 1. Ca(2+) influx into mast cells increased after stimulation by antigen. The increased Ca(2+) uptake by mast cells was inhibited by antiallergic agents, disodium cromoglycate (DSCG) and tranilast, and calcium antagonists, nifedipine and nicardipine. 2. The dose-response curve of histamine release by antigen was different from that by anti-IgE. The maximum release of histamine by house dust was, however, similar to that by anti-IgE. House dust- and anti-IgE-induced release of histamine increased with higher- serum IgE levels. On the contrary, the release of histamine by Candida albicans was not releated to serum IgE levels, and the release by C. albicans did not parallel therelease by anti-IgE ...
Various allergic diseases cause allergic inflammation, which is mediated by mast cells. The current study investigated the anti‑allergic inflammatory effects of formononetin and its mechanism of action in vitro using mast cells. Levels of histamine and pro‑inflammatory cytokines, including tumor necrosis factor‑α (TNF‑α), interleukin (IL)‑1β and IL‑6, were measured to assess the effects of formononetin on allergic inflammation. The activation of intracellular calcium and nuclear factor (NF)‑κB, as well as the activity of caspase‑1, were assessed to determine the mechanism of action. It was determined that difference concentrations of formononetin (0.1, 1 and 10 µM) suppressed histamine release and secretion of TNF‑α, IL‑1β and IL‑6. Further investigations indicated that the effects of formononetin were associated with a reduction of intracellular calcium, suppression of NF‑κB activation and upstream IκKα phosphorylation and inhibition of caspase‑1 activity. ...
Four subjects with clinical histories of milk-induced asthma were studied (three allergic to cows milk; one to soya milk). In each instance, skin prick tests, RAST (IgE and IgG4), the basophil histamine release, and serum precipitins, using appropri
Hello arek, You don?t tell why you have a high histamine. Histamine levels can become elevated for many reasons,and are usually temporary. Anything recommended for lowering your level must be run by your physician. Drug interactions can be problematic and even fatal in persons with an elevated histamine, so please check before attempting to treat yourself. Allergies, surgical procedures, parasitic infections (real parasitic infections such as those contracted from eating raw fish), certain fish and shellfish, fermented foods, wines, salamis, etc. can cause an elevated histamine. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&list_uids=3530640&dopt=Citation ?In humans, histamine ( -imidazole ethylamine) is the most important mediator and is mostly found in the initial phase of an anaphylactic reaction (immediate type allergy). Histamine is produced by the enzymatic decarboxylation of histidine. In the organism, histamine is present in nearly all tissues, and it is mainly ...
Niacin is important for the manufacture of the sex and adrenal hormones; however, along with its primary prosexual effects, shortly after ingestion, niacin can produce sensations of intense warmth accompanied by a tingly itch throughout the body lasting up to 20 minutes. It may also produce a reddish cast to the skin, which is especially pronounced in the extremities. This response is called the "Niacin Flush.". This red, itching warmth caused by niacin use is well known and is harmless. The flush is healthy and indicates that niacin is helping improve blood flow and circulation. Reaction from the Niacin Flush actually mimics an individuals natural sexual response. This natural sex flush, which has been documented by Masters and Johnson, is caused by a large histamine release; in fact, a niacin flush is caused by the same histamine release as the natural sex flush, with one important difference: Because niacin instigates a larger-than-normal histamine release, the results of using niacin are ...
The developers and the researchers have a great responsibility when introducing a new drug into clinical practice, particularly in neuromuscular blocking drugs.7 Dr. Caldwell addresses this issue in his editorial when he compares the side effects of rapacuronium and GW280430A.8 Because we were involved in the clinical evaluation of rapacuronium,9-11 we would like to comment on some relevant aspects of the side effect profiles of both drugs and on the drug approval processes. First, in clinically relevant concentrations, rapacuronium potentates bronchoconstriction most probably by destabilization of the balance between M2 and M3 muscarinic receptors.12 In contrast, GW280430A seems to release histamine3 and therefore may possibly induce bronchoconstriction. Second, although many antihistaminic drugs and prophylactic strategies are available, an effective treatment to rebalance the muscarinic effects of rapacuronium was and is still missing. Third, because rapacuronium did not release histamine,13 ...

Why the immune system mounts an attack against seemingly harmless agents baffles researchers. Because the immune system treats the harmless agent as a threat, B lymphocytes produce immunoglobulin E antibody (IgE). IgE attaches to mast cells such as those present in the nasal and bronchial passages, resulting in histamine release. Inflammation and allergy symptoms follow. Once sensitized, mast cells automatically release histamine when the invading agent reappears. Because IgE can sensitize cells anywhere in the body, individuals symptoms vary (eg, a cat may produce hives in one person and generate sneezing in another person).9,11 Allergy should not be confused with atopy. Atopy indicates that a person has developed a symptomless sensitization. The Increase in Allergies A genetic susceptibility to allergens has been established, but a shift in the human gene pool is an unlikely explanation for the increased prevalence of allergies. Shifts in population-based traits require several generations to ...
If you have MCAS, there are a number of ways to treat the problem. If you want to minimize your symptoms, a low-histamine diet can greatly alleviate the severity of symptoms related to histamine release. You may also want to investigate your sensitivity to salicylate and oxalate as they can trigger the release of histamine secretion.. As mentioned earlier, a digestive imbalance is the key to MCAS. So if you want to treat the problem, you have to make sure you are eating the right foods to treat the imbalance. Here are 5 nutrients that can greatly reset your body and treat MCAS:. 1. Ensure you are taking in your daily recommended dosage of vitamin C in ester form or buffered form. Taking between a daily dosage of 3,000 to 6,000 milligrams can work exceptionally well as a wonderful anti-histamine. It works by reducing mast cells from releasing histamine and causing histamine to break down at a quicker speed.. 2. In order for vitamin C to function at its optimal level, you should also make sure ...
Small, lightweight and battery-powered, Therapik® has been clinically proven to soothe stings and bites from organisms that deliver thermolabile venom and from mosquito saliva containing protein. These proteins cause your skin to release histamines. The type of protein in venom, produced by 20,000 species of insects and sea creatures, can be neutralized with the application of heat by denaturing it. This then stops the skins histamine release that triggered the itch and welts. Using patented technology based on this principle, Therapik® delivers highly concentrated heat to the skin through a small cylindrical opening ...
Allergic subjects release significantly more histamine than normals, exposure to the relevant antigens (P23/TPT1: [§§] locus 13q12-q14) nonessential co-chaperones produces a cytokine (histamine-releasing factor) from a subpopulation of highly allergic donor basophils HRF/p23 can stimulate nonimmune epithelium late allergic reaction (LAR), causing them (basophils) to release histimines.

Purpose of Review: We review basophil testing by flow cytometry with an emphasis on advantages and disadvantages. Recent Findings: There are many tools available to assess the presence and severity of allergic diseases in patients. For 50 years, peripheral blood basophils have been used as tools to study these diseases. It is a very accessible cell that binds IgE antibody and secretes the classical mediators responsible for the symptoms of allergic reactions. In the last decade, an even more accessible methodology, using flow cytometry, has been developed to enhance the ability to use basophils for both mechanistic and clinical diagnostics. Basophil testing has been included in diagnostics for different forms of allergies as well as to monitor disease status. Summary: A variety of studies have begun to establish both precise methods and their clinical relevance for disease diagnosis, but there remain some important questions on how to take optimal advantage of the behaviours of basophils. ...

You can blame your streaming nose on your bodys natural histamine response. When the dedicated patrol members of your immune system, immunoglobulins, detect an invader they rapidly flag other cells in your immune system to take action and release histamine. This is another alarm system that sets off even more body reactions. The cells lining your nose, mouth, even your eyelids are directed to produce and release watery mucus in what seems like gallon quantities ...

Prominent for its nutritious value milk can trigger be allergic to few among us, check the list of foods to avoid with dairy allergy.. Dairy allergy triggers when milk or other dairy related products are treated harmful by immune system. To detect proteins in milk products, your immune system produces antibodies, which signals back to release histamines.. Histamines react with protein substances to result adverse allergic symptoms. According to American Academy, Asthma and Immunology, 80 percent of children with this allergy will outgrow when they reach the age group of 16. Approximately 2.5 percent of infants below the age of 3 are hypersensitive to milk.. ...
Seasonal allergies are a real struggle for many people. Allergies start early in the Spring with tree and bloom pollens, closely followed by Summer grasses and then in the Fall with Molds and Dust. A good portion of my patients take an antihistamine daily all year just to function comfortably. Fortunately, there are many many options for support. Allergies occur when the immune system gets diverted down a pathway that starts to see normal environmental proteins (pollens and dust or food proteins) as foreign invaders instead of inert substances. The immune system goes down a very specific pathway called the TH2 pathway. In this pathway, exposure to the allergen causes activation of MAST cells, which release histamine and the activation of Eosinophils, which are the white blood cells associated with the allergic response. It is believed that this pathway evolved for the purposes of protecting us against parasites but since we dont spend as much time living off the land as we previously did, it ...
Allergies can be topical, respiratory, or digestive, and result in an immune system overreaction to a substance. This can release histamines, which cause wheezing, rashes, sneezing, vomiting, and even anaphylactic shock. People can be allergic to specific foods, plants, animals, and chemicals. Human studies are lacking, and more research is necessary on the anti-allergy potential of various herbs.. Hay fever is a seasonal allergy to pollens and fungi in the air, and can irritate the nose, throat, and eyes. ...
In people who are not allergic, the mucus in the nasal passages simply moves foreign particles to the throat, where they are swallowed or coughed out. But something different happens to a person who is sensitive to airborne allergens.. As soon as the allergen lands on the mucous membranes lining the inside of the nose, a chain reaction occurs that leads the mast cells in these tissues to release histamine and other chemicals. These powerful chemicals contact certain cells that line some small blood vessels in the nose. This allows fluids to escape, which causes the nasal passages to swell, resulting in nasal congestion.. Created by National Institute of Allergy and Infectious Diseases ...
