科学领域:

免疫学免疫学免疫学
遗传学遗传学是一个
分子生物学分子生物学

背景情况:

没有鼻息肉的慢性鼻炎 (CRSsNP) 是慢性鼻炎 (CRS) 的常见表型,但其潜在机制仍然不太清楚.
识别CRSsNP病变的关键分子参与者对于开发有效的治疗策略至关重要.

研究的目的:

通过识别差异表达基因 (DEG) 和枢纽基因,阐明CRSsNP的分子机制.
研究已识别的枢纽基因,特别是IRF4在CRSsNP病原发生中的作用,并探索其作为治疗点的潜力.

主要方法:

使用GEO2R.50对CRSsNP数据集 (GSE36830,GSE198950) 的差异基因表达分析.
蛋白质与蛋白质相互作用网络分析和Cytoscape用于选六个枢纽基因.
构建CRSsNP的小鼠模型,并通过RT-qPCR,HE染色和IHC验证基因表达.
使用ELISA测量炎症性细胞因子 (TNF-α,IL-12,IL-6,IL-1β,IL-18) 和LDH.
对于与热死相关的蛋白质 (NLRP3,Caspase-1,GSDMD) 的西部涂抹.
在体外研究中使用LPS诱导的NP69细胞来评估增殖 (CCK-8) 和亡 (流细胞计).

主要成果:

Drugs Used in Lower Respiratory Disorders: Overview

Lower respiratory tract disorders present challenges that often require skilled and nuanced approaches for effective management. Common ailments, such as asthma and chronic obstructive pulmonary disease (COPD), have prompted the development of intricate treatment strategies involving bronchodilators and anti-inflammatory drugs, each tailored to ease breathing and revitalize the lungs.
Bronchodilators, the first step of respiration enhancement, come in various forms, each with its own mechanism...

Experimental RNAi

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
