[PMID: 34681651 PMCID: PMC8536162 DOI: 10.3390/ijms222010994] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 10/09/2021] [Accepted: 10/09/2021] [Indexed: 02/01/2023] Open
Abstract
Mast cells play a very important role in skin allergy and inflammation, including atopic dermatitis and psoriasis. In the past, it was found that neferine has anti-inflammatory and anti-aging effects on the skin, but its effect on mast cells has not yet been studied in detail. In this study, we used mast cells (RBL-2H3 cells) and mouse models to study the anti-allergic and inflammatory effects of neferine. First, we found that neferine inhibits the degranulation of mast cells and the expression of cytokines. In addition, we observed that when mast cells were stimulated by A23187/phorbol 12-myristate-13-acetate (PMA), the elevation of intracellular calcium was inhibited by neferine. The phosphorylation of the MAPK/NF-κB pathway is also reduced by pretreatment of neferine. The results of in vivo studies show that neferine can improve the appearance of dermatitis and mast cell infiltration caused by dinitrochlorobenzene (DNCB). Moreover, the expressions of barrier proteins in the skin are also restored. Finally, it was found that neferine can reduce the scratching behavior caused by compound 48/80. Taken together, our results indicate that neferine is a very good anti-allergic and anti-inflammatory natural product. Its effect on mast cells contributes to its pharmacological mechanism.

Inhibitory Effects of AF-343, a Mixture of Cassia tora L., Ulmus pumila L., and Taraxacum officinale, on Compound 48/80-Mediated Allergic Responses in RBL-2H3 Cells. Molecules 2020; 25:molecules25102434.

Abstract
The purpose of this study was to determine the antiallergic effects of AF-343, a mixture of natural plant extracts from Cassia tora L., Ulmus pumila L., and Taraxacum officinale, on rat basophilic leukemia (RBL-2H3) cells. The inhibitory effects on cell degranulation, proinflammatory cytokine secretion, and reactive oxygen species (ROS) production were studied in compound 48/80-treated RBL-2H3 cells. The bioactive compounds in AF-343 were also identified by HPLC–UV. AF-343 was found to effectively suppress compound 48/80-induced β-hexosaminidase release, and interleukin (IL)-4 and tumor necrosis factor-α (TNF-α) production in RBL-2H3 cells. In addition, AF-343 exhibited DPPH free radical scavenging effects in vitro (half-maximal inhibitory concentration (IC50) = 105 μg/mL) and potently inhibited compound 48/80-induced cellular ROS generation in a 2′,7′-dichlorofluorescein diacetate (DCFH-DA) assay. Specifically, treatment with AF-343 exerted stronger antioxidant effects in vitro and antiallergic effects in cells than treatment with three single natural plant extracts. Furthermore, AF-343 was observed to contain bioactive compounds, including catechin, aurantio-obtusin, and chicoric acid, which have been reported to elicit antiallergic responses. This study reveals that AF-343 attenuates allergic responses via suppression of β-hexosaminidase release, IL-4 and TNF-α secretion, and ROS generation, perhaps through mechanisms related to catechin, aurantio-obtusin, and chicoric acid. The results indicate that AF-343 can be considered a treatment for various allergic diseases.

Abstract
Sting accident by honeybee causes severe pain, inflammation and allergic reaction through IgE-mediated anaphylaxis. In addition to this hypersensitivity, an anaphylactoid reaction occurs by toxic effects even in a non-allergic person via cytolysis followed by similar clinical manifestations. Auto-injectable epinephrine might be effective for bee stings, but cannot inhibit mast cell lysis and degranulation by venom toxins. We used connective tissue type canine mast cell line (CM-MC) for finding an effective measure that might inhibit bee venom toxicity. We evaluated degranulation and cytotoxicity by measurement of β-hexosaminidase release and MTT assay. Melittin and crude bee venom induced the degranulation and cytotoxicity, which were strongly inhibited by mono-sialoganglioside (G(M1)), di-sialoganglioside (G(D1a)) and tri-sialoganglioside (G(T1b)). In contrast, honeybee venom-derived phospholipase A(2) induced the net degranulation directly without cytotoxicity, which was not inhibited by G(M1), G(D1a) and G(T1b). For analysis of distribution of Gα(q) and Gα(i) protein by western blotting, lipid rafts were isolated by using discontinuous sucrose gradient centrifuge. Melittin disrupted the localization of Gα(q) and Gα(i) at lipid raft, but gangliosides stabilized the rafts. As a result from this cell-based study, bee venom-induced anaphylactoid reaction can be explained with melittin cytotoxicity and phospholipase A(2)-induced degranulation. Taken together, gangliosides inhibit the effect of melittin such as degranulation, cytotoxicity and lipid raft disruption but not phospholipase A(2)-induced degranulation in mast cells. Our study shows a potential of gangliosides as a therapeutic tool for anaphylactoid reaction by honeybee sting.

Abstract
The effects of lipo-chitin oligosaccharide Nod factors (NodNGR[S] from Rhizobium sp. NGR234) on root hair deformation in Vigna unguiculata (L.) Walp. were studied using pharmacological agents to mimic and/or inhibit their action. It was hypothesised that the rearrangement of the cytoskeleton seen during Nod factor induced root hair deformation is modulated by protein kinase C, monomeric G proteins of the Rho superfamily and the location and amount of phosphatidylinositol 3-phosphates (PI3Ps). This hypothesis is supported by the following observations. The protein kinase C activators, 12-deoxyphorbol 13-acetate (DPA) and diacylglycerol kinase inhibitor 1, stimulated root hair deformation to a level similar to that seen with Nod factors or mastoparan, whereas the inhibitor Gö 6976 inhibited root hair deformations induced by NodNGR[S], mastoparan, DPA and diacylglycerol kinase inhibitor 1. The Ras antagonists mevastatin and sulindac sulphide, and the Rho antagonist exoenzyme C3 toxin from Clostridium botulinum all inhibited Nod factor stimulated root hair deformation. Pasteurella multocida toxin activates Rho and stimulated root hair deformation, this stimulation was inhibited by both neomycin and exoenzyme C3 toxin. The PI3 kinase inhibitors, wortmannin and LY-294002 attenuated Nod factor induced root hair deformation. These studies were complemented with actin immunoprecipitations of root hair enriched microsomal membrane preparations from V. unguiculata which pulled down small GTP binding proteins. Root hair deformation is an important early stage in the formation of nitrogen fixing nodules and this study highlights that these processes may depend on signalling cascades involving phospholipids and small GTP binding proteins.

Abstract
Our previous study described a novel biologic function of compound 48/80 (48/80) in the downregulation of monocytic tissue factor (TF)-initiated hypercoagulation in response to bacterial endotoxin (lipopolysaccharide; LPS). The inhibition was not due to the blockade of LPS cell signaling, as evidenced by the unaffected LPS-induced TF synthesis. We herein determined the mechanism by which 48/80 inhibits the extrinsic coagulation in agonist-challenged THP-1 monocytes. LPS as well as A23187 substantially induced TF activity. TF synthesis was enhanced by LPS but not by A23187. However, the elevated FVII binding to monocytes accompanying the upregulation of factor VII (FVII) activation was uniformly observed in both cases. A 5-min preincubation of the cells with a sheep anti-humanTF antibody (anti-hTF Ab) showed the downregulation of FVII activation, indicating a regulatory role of FVII binding in the modulation of the extrinsic coagulation. The 48/80 blocked FVII binding to monocytes, leading to the preferential inhibition of FVII activation. As the result of the diminished FVIIa formation, monocytic TF-initiated extrinsic coagulation was downregulated in agonist-challenged THP-1 monocytes.

Abstract
Hypercoagulation with upregulated monocytic tissue factor (TF) activity often occurs under a variety of inflammatory conditions including endotoxemia. The antagonism to bacterial endotoxin (LPS) signaling often results in the depression in TF upregulation. We herein report that compound 48/80 (48/80) significantly depressed LPS-induced TF activity in human and cebus monkey peripheral blood monocytes. Employing a model monocyte-like cell line (THP-1), we explored the regulatory mechanism to identify the inhibitory site(s) of 48/80. We determine whether the inhibition results from the blockade of LPS signaling. 48/80 dose-dependently inhibited LPS-induced TF activity. Chase of LPS-challenged cells with 48/80 also significantly offset TF upregulation. In immunofluorescent approaches, FACScan analysis revealed that 48/80 had no effect on either LPS recognition or the expression of its receptors (CD14 and CD11b). Moreover, LPS-induced TF expression as well as synthesis remained unaffected in the presence of 48/80. Consistent with the independence of LPS action, 48/80 was also able to inhibit TF activity induced by A23187, ionomycin, or Quin-2 AM. Interestingly, 48/80 significantly decreased the FVII binding to either resting or LPS-challenged cells. In conclusion, our results elucidate that the inhibitory action of 48/80 was independent of LPS signaling including recognition, receptor expression, and the induced TF expression/ synthesis. However, 48/80 was able to directly block FVII binding to monocytic TF, thereby resulting in such antagonism to LPS-induced TF-initiated extrinsic coagulation.

Abstract
Nociceptin (20 microg/kg i.p.) strongly inhibited cutaneous Evans blue accumulation in the chronically denervated hindpaw of the rat in response to mast cell degranulating peptide (MCDP, 0.25 microg in 100 microl) but it had no and marginal effect on plasma extravasation induced by 5-hydroxytryptamine (5-HT, 0.5 microg in 100 microl) and histamine (0.1 microg in 100 microl), respectively. Release of sensory neuropeptides such as substance P, calcitonin gene-related peptide (CGRP) and somatostatin from the rat isolated trachea in response to capsaicin (10(-8) M) or bradykinin (10(-7) M) were also attenuated by nociceptin (100 and 300 nM). It is concluded that chemically induced discharge of mediators from mast cells and from capsaicin-sensitive afferent nerve terminals are both inhibited by nociceptin that participates in the anti-inflammatory effect of the peptide.

Abstract
Some basic amphiphilic peptides are known to directly stimulate heterotrimeric GTP-binding proteins (G proteins). Mastoparan and melittin are known to stimulate Gi activities. Here, we found melittin inhibited guanine nucleotide-dependent adenylyl cyclase activity in synaptic membranes of the rat cerebral cortex. However, in insect cell membranes overexpressing specific heterotrimeric G proteins using baculovirus expression system, melittin showed unique effects different from those by mastoparan on G protein activities. This peptide markedly stimulated Gi1 and G11 activities, whereas it did inhibit Gs activities. Kinetic studies revealed that the inhibition of Gs activity by melittin is attributed to the inhibition of GDP release in exchange for added guanine nucleotides (or the association of guanine nucleotides). Thus, melittin may be the first metabostatic peptide inhibiting G protein (Gs) activity, and both mechanisms through the stimulation of Gi and inhibition of Gs might be involved in the melittin-induced inhibition of adenylyl cyclase.

Abstract
Integrated chorda tympani (CT) recordings were made to salty, sour, sweet, bitter, and glutamate tastants before and after a 4-min application of modulators of lipid-derived second messenger systems. The modulators included two membrane-permeable analogues of DAG, 1-oleoyl-2-acetyl glycerol (OAG) and dioctanoyl glycerol (DiC8); thapsigargin, which releases Ca++ from intracellular stores; ionomycin, a calcium ionophore; lanthanum chloride, an inorganic calcium channel blocker; nifedipine, a dihydropyridine calcium channel blocker; quinacrine diHCl, a phospholipase A2 antagonist; melittin, a phospholipase A2 agonist; and indomethacin, which decreases the release of prostaglandins by inhibiting the enzyme cyclo-oxygenase. The main findings were: OAG (125 microM) and DiC8 (100 microM) blocked the responses of several bitter compounds while enhancing the taste response to several sweeteners. Lanthanum chloride blocked all responses, which may be due to the fact that it blocks tight junctions. Quinacrine (1 mM) suppressed several bitter responses while enhancing the response to several sweeteners. The enhancement of sweet taste responses by DAG analogues suggests that there is cross-talk between the adenylate cyclase system and one (or more) pathways involving lipid-derived second messengers in taste cells.

Abstract
Small GTP-binding proteins of the rab family have been implicated as regulators of membrane traffic along the biosynthetic and endocytic pathways in eukaryotic cells. We have investigated the localization and function of rab8, closely related to the yeast YPT1/SEC4 gene products. Confocal immunofluorescence microscopy and immunoelectron microscopy on filter-grown MDCK cells demonstrated that, rab8 was localized to the Golgi region, vesicular structures, and to the basolateral plasma membrane. Two-dimensional gel electrophoresis showed that rab8p was highly enriched in immuno-isolated basolateral vesicles carrying vesicular stomatitis virus-glycoprotein (VSV-G) but was absent from vesicles transporting the hemagglutinin protein (HA) of influenza virus to the apical cell surface. Using a cytosol dependent in vitro transport assay in permeabilized MDCK cells we studied the functional role of rab8 in biosynthetic membrane traffic. Transport of VSV-G from the TGN to the basolateral plasma membrane was found to be significantly inhibited by a peptide derived from the hypervariable COOH-terminal region of rab8, while transport of the influenza HA from the TGN to the apical surface and ER to Golgi transport were unaffected. We conclude that rab8 plays a role in membrane traffic from the TGN to the basolateral plasma membrane in MDCK cells.

Abstract
The amphiphilic agents melittin, compound 48/80 and mastoparan inhibit ADP-ribosylation of porcine brain rho protein by Clostridium botulinum exoenzyme C3. However, ADP-ribosylation of recombinant rhoA expressed in E.coli was not inhibited by these agents. Accordingly, steady state GTP hydrolysis by recombinant rhoA was not stimulated by mastoparan, whereas GTP hydrolysis by porcine brain rho was stimulated 2.5-fold in the presence of this wasp venom. After microinjection of recombinant rhoA into Xenopus laevis oocytes the inhibitory effect of mastoparan on C3 ADP-ribosylation was restored. The data suggest that the amphiphilic agents tested are only active at the posttranslationally processed form of rho and that they exert their effects via the C-terminal end.
