Abstract
The development of new effective anti-coronavirus drugs and therapies is important, but it requires significant human, financial and, most importantly, time expenditures. The current pandemic is neither the first nor the last. Humanity has already accumulated considerable survival experience. We cannot do without prevention and epidemiological protection measures. This study reviews medicinal plants that grow in Northeast Asia and whose antioxidant, antiviral, anti-inflammatory and immunomodulatory characteristics are already known, also in the framework of the prevention and treatment of pneumonia of various etiologies. The need for a comprehensive approach to maintaining immunodefences, including functional foods and positive emotions, is emphasized. In the period of pandemics, it is important to research various areas that allow to us accumulate a critical mass of information and cope with the next global disease.

Comparing the Protection Imparted by Different Fraction Extracts of Garlic ( Allium sativum L.) against Der p-Induced Allergic Airway Inflammation in Mice. Int J Mol Sci 2019; 20:ijms20194879. [PMID: 31581442 PMCID: PMC6801723 DOI: 10.3390/ijms20194879] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2019] [Revised: 09/19/2019] [Accepted: 09/29/2019] [Indexed: 01/02/2023] Open
Abstract
Garlic (Allium sativum L.) has been used extensively as a food ingredient and medicinally, but the effect on asthmatic airway inflammation has not been studied in detail. We accordingly explored the protective effects exerted by various garlic fraction extracts against airway inflammation with Dermatophagoides pteronyssinus (Der p)-induced allergic asthma in vivo and in vitro. Garlic extraction was realized using n-hexane, dichloromethane, ethylacetate, n-butanol, and water in sequence to obtain different fraction extracts. Mice were orally administered different fractions (80 mg/kg) daily for four weeks. The histological results showed that the water fraction could ameliorate lung-based goblet cell hyperplasia, inflammatory cell infiltration, and mucus hypersecretion. The water fraction extracts decreased IgE and IgG1, and they decreased inflammatory cells as quantified in bronchoalveolar lavage fluid (BALF); however, they increased IgG2a in serum. Moreover, the water fraction extracts increased IFN-γ and IL-12 (both constituting Th1 cytokines) in BALF, but they reduced IL-13, -4, and -5 (all constituting Th2 cytokines), and also inhibited the expression of IL-1β, IL-6, and TNF-α. The water fraction also inhibited the PI3K/Akt/NF-κB signal pathways in A549 cells. These findings suggest that water fraction extracts of garlic have a clear anti-inflammatory effect on Der p-induced allergic asthma.

Phenotype-Specific Therapeutic Effect of Rhodiola wallichiana var. cholaensis Combined with Dexamethasone on Experimental Murine Asthma and Its Comprehensive Pharmacological Mechanism. Int J Mol Sci 2019; 20:ijms20174216. [PMID: 31466312 PMCID: PMC6747379 DOI: 10.3390/ijms20174216] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2019] [Revised: 08/17/2019] [Accepted: 08/26/2019] [Indexed: 12/14/2022] Open
Abstract
The heterogeneity of asthma involves complex pathogenesis leading to confusion regarding the choice of therapeutic strategy. In the clinic, asthma is commonly classified as having either eosinophilic asthma (EA) or non-eosinophilic asthma (NEA) phenotypes. Microbiota colonizing in airways has been demonstrated to induce distinct phenotypes of asthma and the resistance to steroids. Rhodiola wallichiana var. cholaensis (RWC) has the potential to alleviate asthmatic inflammation according to recent studies, but its pharmacological mechanisms remain unclarified. In our study, murine asthmatic phenotypes were established and treated with RWC and/or dexamethasone (DEX). Combined treatment with RWC and DEX could improve spirometry and airway hyperresponsiveness (AHR) in asthmatic phenotypes, alleviate steroid resistance in NEA, and reduce the inflammatory infiltration of the both phenotypes. The combined treatment increased Th1, regulated the imbalance of Th2/Th1, and decreased the related cytokines in EA. As for NEA, the combined treatment reduced Th17 and promoted the accumulation of regulatory T cells (Tregs) in lung. A microbiome study based on 16S rDNA sequencing technique revealed the significantly changed structure of the lower airway microbiota after combined treatment in NEA, with 4 distinct genera and 2 species identified. OPLS-DA models of metabolomics analysis based on UPLC-Q/TOF-MS technique identified 34 differentiated metabolites and 8 perturbed metabolic pathways. A joint multiomics study predicted that the colonized microbiota in airways might be associated with susceptibility of asthma and steroid resistance, which involved systematic and pulmonary metabolic perturbation. In summary, the pharmacological network of RWC included the complicated interaction mechanisms of immune regulation, microbiota change, and metabolic perturbation.

Int J Mol Sci 2019; 20:E1463. [PMID: 30909474 PMCID: PMC6470777 DOI: 10.3390/ijms20061463] [Citation(s) in RCA: 72] [Impact Index Per Article: 14.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Accepted: 03/20/2019] [Indexed: 12/17/2022] Open
Abstract
Astragali radix (AR) is one of the most widely used traditional Chinese herbal medicines. Modern pharmacological studies and clinical practices indicate that AR possesses various biological functions, including potent immunomodulation, antioxidant, anti-inflammation and antitumor activities. To date, more than 200 chemical constituents have been isolated and identified from AR. Among them, isoflavonoids, saponins and polysaccharides are the three main types of beneficial compounds responsible for its pharmacological activities and therapeutic efficacy. After ingestion of AR, the metabolism and biotransformation of the bioactive compounds were extensive in vivo. The isoflavonoids and saponins and their metabolites are the major type of constituents absorbed in plasma. The bioavailability barrier (BB), which is mainly composed of efflux transporters and conjugating enzymes, is expected to have a significant impact on the bioavailability of AR. This review summarizes studies on the phytochemistry, pharmacology and pharmacokinetics on AR. Additionally, the use of AR as a personalized medicine based on the BB is also discussed, which may provide beneficial information to achieve a better and more accurate therapeutic response of AR in clinical practice.

Abstract
Abnormal proliferation and migration of airway smooth muscle cells (ASMCs) have been found to be important for the airway remodeling during the pathogenesis of asthma. Salidroside a bioactive glucoside that exerts antitumor activity via inhibiting the cell proliferation and migration of cancer cells. The aim of the current study was to evaluate the effects of salidroside on the proliferation and migration of ASMCs. Our results showed that salidroside inhibited the proliferation and migration of ASMCs in response to platelet-derived growth factor (PDGF) stimulation. Salidroside markedly attenuated the PDGF-induced production of matrix metalloproteinase 2 (MMP-2) and MMP-9 in ASMCs. The levels of contractile phenotype markers including smooth muscle α-actin and calponin were reduced in response to PDGF stimulation, which was attenuated by salidroside pretreatment. Salidroside diminished the increase in the expression levels of type I collagen and fibronectin in PDGF-stimulated ASMCs. Furthermore, salidroside blocked the PDGF-induced activation of the nuclear factor-κB (NF-κB) pathway in ASMCs. The results suggested that salidroside functionally regulated the proliferation, migration, phenotype plasticity, and extracellular matrix deposition in PDGF-induced ASMCs and the NF-κB pathway might be implicated in the effects of salidroside on ASMCs induced by PDGF.

Regulatory T cells regulate the distribution of natural killer T cells through CD39 signal transduction in asthma. Hum Cell 2018; 32:141-149. [PMID: 30539423 DOI: 10.1007/s13577-018-00226-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2018] [Accepted: 11/29/2018] [Indexed: 12/12/2022]
Abstract
Natural killer T cells (NKT cells) and regulatory T cells (Treg cells) are two important immune regulatory cells which both play critical roles in asthma. Our previous experiments revealed that activation of Treg cells suppressed NKT cells in asthma. However, the possible regulatory effects and the mechanisms linking Treg cells and NKT cells remain poorly understood. The current study was designed to further investigate the regulatory effect and its possible mechanisms of Treg cells on NKT cells function, especially the distribution of NKT cells. Regulatory T cell (Treg), responder T cell (Teff) and Natural killer T cell (NKT) were isolated and purified. After Lentivirus carrying CD39 (Le-CD39) was transfected into Treg cells, the immune phenotype of Treg cells was changed and the suppressive effect of Treg cells on Teff cells with an activation of Treg cells was enhanced, marking with a high expression level of interleukin 10 (IL-10) and transforming growth factor β (TGF-β). Up-regulation of CD39 expression led to lower ATP level in cell culture supernatant. To further explore its function in asthma, we introduced an ovalbumin (OVA)-induced mice model of asthma. And the data showed that up-regulation of CD39 remarkably alleviated OVA-induced hallmarks of the asthma and increased NKT cells in the spleen and peripheral blood; however, decreased NKT cells in the lung. Furthermore, up-regulation of CD39 decreased the levels of interleukin 4 (IL-4) and interferon γ (IFN-γ) in the lung of OVA-treated mice. Our results strongly suggest that Treg cells could be activated by CD39 signal transduction and then affected the distribution of NKT cells in the OVA-induced mice model of asthma.

The Cell Research Trends of Asthma: A Stem Frequency Analysis of the Literature. JOURNAL OF HEALTHCARE ENGINEERING 2018; 2018:9363820. [PMID: 30210753 PMCID: PMC6126072 DOI: 10.1155/2018/9363820] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 03/26/2018] [Accepted: 07/22/2018] [Indexed: 02/06/2023]
Abstract
Objective This study summarized asthma literature indexed in the Medical Literature Analysis and Retrieval System Online (MEDLINE) and explored the history and present trends of asthma cell research by stem frequency ranking to forecast the prospect of future work. Methods Literature was obtained from MEDLINE for the past 30 years and divided into three groups by decade as the retrieval time. The frequency of stemmed words in each group was calculated using Python with Apache Spark and the Natural Language Tool Kit for ranking. The unique stems or shared stems of 3 decades were summarized. Results A total of 1331, 4393, and 7215 records were retrieved from 3 decades chronologically, and the stem ranking of the top 50 were listed by frequency. The number of stems shared with 3 decades was 26 and with the first and last 2 decades was 5 and 13. Conclusions The number of cell research studies of asthma has increased rapidly, and scholars have paid more attentions on experimental research, especially on mechanistic research. Eosinophils, mast cells, and T cells are the hot spots of immunocyte research, while epithelia and smooth muscle cells are the hot spots of structural cell research. The research trend is closely linked with the development of experimental technology, including animal models. Early studies featured basic research, but immunity research has dominated in recent decades. The distinct definition of asthma phenotypes associated with genetic characteristics, immunity research, and the introduction of new cells will be the hot spots in future work.
