In the present study, ethanol extracts of 90 wild mushroom samples from Nepal, and the pure compound hispidin, were screened for their ability to inhibit β-hexosaminidase release (BHR) from rat basophilic leukemia-2H3 cells. Simultaneously, the toxicity of the extracts toward the cells was also

Wild rice (Zizania spp.), an important aquatic cereal grain in North America and East Asia, has attracted interest worldwide because of its antioxidant activities and health-promoting effects. Wild rice is high in protein, minerals, and vitamins but is low in fat. The phytochemical content

IL-18 is a proinflammatory cytokine that plays an important role in natural killer cell activation and T helper 1 (Th1) cell responses. Mast cells and basophils are major inducers and effectors of allergic inflammation. Here we show that basophils and mast cells derived by culture of bone marrow

Protein tyrosine phosphatases and glucocorticoids are known to regulate allergic and antiallergic action in activated mast cells. Here we provide RNA sequencing and quantitative real-time PCR data from bone marrow derived mast cells, for wild-type and PEST-domain-enriched tyrosine phosphatase (PEP)

OBJECTIVE Although the 'cromones' (di-sodium cromoglycate and sodium nedocromil) are used to treat allergy and asthma, their 'mast cell stabilising' mechanism of pharmacological action has never been convincingly explained. Here, we investigate the hypothesis that these drugs act by stimulating the

OBJECTIVE To determine whether the inhibitory action of the antiallergic cromone "mast cell stabilizing" drugs on polymorphonuclear leukocyte (PMN) trafficking is mediated through an annexin-A1 (Anx-A1) dependent mechanism. RESULTS Intravital microscopy was used to monitor the actions of cromones in

The antiallergic agent bepotastine besilate is a nonsedating, second-generation H1-antagonist with high oral absorption and negligible distribution into brain. To clarify the role of P-glycoprotein (P-gp) in the pharmacokinetics of bepotastine, intestinal absorption and brain penetration studies

Zizania latifolia (tribe Oryzeae Dum., subfamily Oryzoideae Care, family Gramineae) is native to East Asian countries. The seeds of Z. latifolia (Chinese wild rice) have been consumed as a cereal in China for >3000 years. Z. latifolia forms swollen culms when infected with Ustilago esculenta, which

The cell-autonomous circadian clock regulates IgE- and IL-33-mediated mast cell activation, both of which are key events in the development of allergic diseases. Accordingly, clock modifiers could be used to treat allergic diseases, as well as many other circadian-related diseases, such as sleep and

Heat-killed cells of Lactobacillus plantarum L-137 are potent inducers of IL-12 in vitro as well as in vivo and have been shown to have antiallergic, antitumor, and antiviral effects through this induction, which leads to a Th1 type immune response. To determine why L-137 cells induce much greater

Transient expression of the wild-type human histamine H(1) receptor in SV40-immortalised African green monkey kidney cells resulted in an agonist-independent elevation of the basal levels of the second messenger inositoltrisphospate. Several histamine H(1) receptor antagonists, including the

Objectives: New generation of allergy vaccines is capable of promoting the development of protective IgG and blocking the functionality of allergen-specific IgE. We incorporated universal and powerful T-cell epitopes from tetanus and

Chicory (Cichorium intybus L) is a bushy perennial herb with blue, lavender, or occasionally white flowers. It grows as a wild plant on roadsides in its native Europe, and in North America, where it has become naturalized. Common chicory is also known as blue sailors, succory, and coffeeweed.

Although lactic acid bacteria (LAB) affect the immune system, for example, having an anti-allergic effect, little is known about the actual mechanisms of immune modulation. Toll-like receptors (TLRs) recognize conserved microbial molecular patterns, and are presumed to be involved in the recognition

Glycyrrhiza uralensis roots used in this study were produced using novel cultivation systems, including artificial hydroponics and artificial hydroponic-field hybrid cultivation. The equivalency between G. uralensis root extracts produced by hydroponics and/or hybrid cultivation and a commercial
