What is the role of histamine in the immune system?
This biogenic amine acts on a variety of cell types, including smooth muscle cells, neurons, endocrine and exocrine cells, blood cells, and cells of the immune system [6]. In scientific research, much attention is paid to the role of histamine in the immune response in allergic inflammation and anaphylaxis. Allergic diseases such as allergic asthma, pruritus, atopic dermatitis, and allergic rhinitis arise from complex interactions between inflammatory cells, including mast cells, basophils, lymphocytes, dendritic cells, neutrophils, and eosinophils, in response to various environmental factors [7,8]. These cells produce a variety of inflammatory mediators such as histamine, eicosanoids, chemokines, cytokines, and reactive oxygen species [9]. Among them, the mast cell histamine is a pivotal player in stimulating the development of inflammatory diseases associated with allergies by regulating the maturation and activation of leukocytes and directing their migration to target sites, where they induce chronic inflammation [10,11]. Histamine also performs various other immunoregulatory functions by modulating the functions of monocytes [12], T cells [13], macrophages [14], neutrophils [15], and other immune response cells [8].
What is the reason for the excess histamine?
The reason for the excess histamine is the inhibition of DAO by widely used mucolytic (ambroxol, acetylcysteine), antiemetic (metoclopramide), antiarrhythmic (verapamil, prajmalium), and antihypertensive drugs (dihydralazine), as well as antidepressants (amitriptylerline) and other drugs [19,35].
How is histamine metabolized?
In the human body, histamine is metabolized in two ways: (1) extracellular oxidative deamination of the primary amino group by the enzyme diamine oxidase (DAO) and (2) intracellular methylation of the imidazole ring by the enzyme histamine N-methyltransferase. Inhibition of enzymes is carried out by reaction products of the type of negative feedback and xenobiotics (drugs). Oxidative deamination of histamine DAO leads to the formation of imidazole acetaldehyde, then via aldehyddehydrogenase, imidazole-4-acetic acid is formed. The latter product, after the attachment of the ribose molecule, forms another form for excretion. The product of histamine methylation, catalyzed by histamine-N-methyltransferase, is tele-methylhistamine, which is subsequently converted by monoamine oxidase to tele-methylimidazole acetaldehyde. The latter is then converted to tele-methylimidazoleacetic acid with the participation of aldehyde dehydrogenase.
What is enteric histaminosis?
Histamine intolerance , called enteric histaminosis or dietary histamine sensitivity, is a disorder associated with an impairment in the ability to metabolize this metabolite [24]. Food histamine enters the body through the intestinal epithelium. The main role in the metabolism of exogenous (food, microbiota) histamine is played by DAO [18,25,26]. The key role of DAO in histamine metabolism was confirmed in the second half of the 20th century in numerous studies in animal models and in vitro. In animal models, enteral-induced histaminosis was observed under conditions of an excess of histamine in the intestinal lumen, factors that reduce DAO activity in intestinal cells, or a high content of free histamine circulating in the bloodstream [18,25,26,27]. Subsequently, negative symptoms of enteral histominosis have been demonstrated in humans [19,28].
How does histamine affect the body?
Histamine has a multifaceted effect on metabolic transformations in the human body in health and disease by activating four subtypes of rhodopsin-like G-protein-coupled receptors (GPRC) (H1, H2, H3, and H4) [39]. The receptor subtypes are characterized by varying affinity for the target histamine molecule [40]. Receptors H1 and H2 exhibit low affinity for histamine with a dissociation constant Kd~ μM. While the H3 and H4 subtypes have high affinity, their Kdis ~5–10 nM [41]. The genes encoding HR synthesis are subject to alternative splicing. Their activity can vary depending on the homeostatic conditions [42] (Figure 2).
What is the biogenic amine in fish?
Histamine and related biogenic amines (tyramine and putrescine) enter the body with food. Their content is especially high in high-protein nutrients (fish or meat) that are stored in unsuitable conditions or significantly contaminated with microorganisms. The enzyme histidine decarboxylase, which catalyzes the formation of histamine from the amino acid histidine, remains active even at relatively low temperatures and is quickly reactivated after thawing. Direct contact of fish and meat with bacteria occurs during cutting, chopping, and mixing with vegetables. Some histamine-forming bacteria are resistant to table salt and are even halophilic, which means they actively produce histamine when salted, smoked, or dried. A number of histamine-generating bacteria are facultative anaerobes that remain viable in vacuum packaging. Histamine accumulation is quite resistant to high and low temperatures [70]. Approximately 40% of the toxic reactions associated with the consumption of fish and seafood are precisely caused by the action of biogenic amines. Because such cases were more often recorded with fish of the suborder Scombridae (mackerel, tuna), the term “scombroid poisoning” was previously used. The World Health Organization (WHO) recommends labeling this condition as “histamine intoxication” [71]. The corresponding symptoms appear after a few minutes each hour and include perspiration, burning in the mouth and throat, urticaria and itching, arterial hypotension, tachycardia, headache and dizziness, nausea, vomiting, diarrhea, and bronchial obstruction [71,72]. An increased content of histamine and serotonin is noted in fermentation products (cheeses, wine, canned food, pickled vegetables, and some drinks). Lactic acid bacteria (Lactobacillus hilgardii, L. buchnerii, L. curvatus, and Oenococcus oeni) and some strains of enterobacteria can be important sources of histamine [71,72]. A meta-analysis of scientific reports revealed that in 98% of cases, the cause of histamine intoxication was the consumption of fish and seafood, while the remaining 2% were due to cheese consumption [73].
Where is histamine concentrated in cells?
In cells, histamine is concentrated mainly in the microsomes and the nucleus. Nuclear chromatin has the highest affinity for histamine; however, this affinity decreases with active DNA division during regeneration [22]. The main depot cells of histamine are basophils and mast cells in the endoplasmic granules, which accumulate in significant amounts (>90% of the total intracellular pool). The regulatory role of histamine in the cell is not well understood; therefore, pharmacological intervention that affects its intracellular metabolism can lead to unpredictable consequences [23].
What is quercetin used for?
Quercetin is the great representative of polyphenols, flavonoids subgroup, flavonols. Its main natural sources in foods are vegetables such as onions, the most studied quercetin containing foods, and broccoli; fruits (apples, berry crops, and grapes); some herbs; tea; and wine. Quercetin is known for its antioxidant activity in radical scavenging and anti-allergic properties characterized by stimulation of immune system, antiviral activity, inhibition of histamine release, decrease in pro-inflammatory cytokines, leukotrienes creation, and suppresses interleukin IL-4 production. It can improve the Th1/Th2 balance, and restrain antigen-specific IgE antibody formation. It is also effective in the inhibition of enzymes such as lipoxygenase, eosinophil and peroxidase and the suppression of inflammatory mediators. All mentioned mechanisms of action contribute to the anti-inflammatory and immunomodulating properties of quercetin that can be effectively utilized in treatment of late-phase, and late-late-phase bronchial asthma responses, allergic rhinitis and restricted peanut-induced anaphylactic reactions. Plant extract of quercetin is the main ingredient of many potential anti-allergic drugs, supplements and enriched products, which is more competent in inhibiting of IL-8 than cromolyn (anti-allergic drug disodium cromoglycate) and suppresses IL-6 and cytosolic calcium level increase.
What are the effects of polyphenols on the immune system?
Polyphenols are considered effective anti-allergy agents capable of influencing multiple biological pathways and immune cell functions in the allergic immune response . Among the most investigated plant-derived polyphenolic compounds (flavonoids), quercetin, together with resveratrol, epigallocatechol-3-gallate, and genistein, have exhibited potent effects on cellular and humoral immune functions in pre-clinical investigations [70]. The interaction of polyphenols with proteins can modulate the process of allergic sensitization and their direct effect on allergic effector cells such as mast cells inhibit mediator release, resulting in the alleviation of symptoms [3]. Polyphenols inhibit histamine release from human basophils and murine mast cells [71,72].
What is the most commonly studied flavonoid?
Quercetin belongs to the most frequently studied flavonoids that is, together with kaempferol, the most ubiquitous in plant foods although they are generally presented at relatively low concentrations of 15–30 mg/kg FW (fresh weight) [11] except several vegetable varieties with extensive content, such as onions and shallots. Quercetin and its glycosylated forms represent 60%–75% of flavonoid intake [12]. Generally, quercetin occurs in natural plant sources such as various types of vegetable (onions, broccoli, and peppers) [13,14,15], caper fruits [16], different kinds of fruits (apples, various berries, and grapes) [17,18,19], herbs (dill) [20], and some types of tea [21] and wine [22,23].
Is quercetin in apples?
In apples, another great quercetin source , there are well studied antioxidant compounds such as quercetin-3-galactoside, quercetin-3-glucoside, and quercetin-3-arabinoside [33,41] in the content range of 21–72 mg/kg; quercetin-3-rhamnoside [52]; and quercetin-3-rutinoside [28]. Quercetin conjugates are present entirely in the apple peels [28,53]. Due to the presence of more antioxidants such as quercetin in the apple peel than in the flesh, the apple peels may be considered to have higher antioxidant capacity and also bioactivity [54]. In apples, other dietary quercetin glycosides such as quercetin galactosides are also found [34].
Is quercetin anti-inflammatory?
The anti-allergic and anti-inflammatory properties of quercetin have been proved by several studies, in animal models and in vitro, as presented in Table 1.
