TH17细胞分化及其调控机制研究进展

在过去二十年里,对TH1和TH2细胞的分类构成了人们理解CD4+T细胞免疫学功能及它们在天然免疫和适应性免疫调节中作用的基础.近年来,新的免疫学理论认为初始T细胞可以在不同细胞因子及环境因素作用下分化为TH1、TH2、TH17和Treg细胞,几种效应细胞分别受到不同转录因子的调控,在体内产生不同的生物学功能.TH17细胞的发现更多的是与自身免疫性疾病的研究相关,它是T细胞分化过程中一种特殊的细胞亚群.初始T细胞在TGF-β和IL-6共同作用下分化为TH17细胞.同时它的分化受体内多种因素的调控.本文将从效应T细胞TH1和TH2、Treg细胞及DC细胞等对TH17细胞分化影响的角度分析TH17分化及其调控机制,这将对深入理解TH17细胞形成、分化和体内调控,并为自身免疫疾病和炎症冶疗提供一定的理论依据.

对运动性蛋白尿分子机制的探讨

蛋白尿是肾功能不全的早期表现。许多学者认为,长期蛋白尿可作为独立的致病因子引起肾损伤的加重。运动性蛋白尿是蛋白尿的一种表现,有人已提出大强度运动出现蛋白尿可能是肾脏损害的趋势。本文主要分析蛋白尿分子机制的研究近况．旨在推动运动性蛋白尿分子机制的研究。

乳腺癌细胞粘附分子CD_(15)的表达及其与预后因素的关系

应用免疫组化SP法对94例乳腺癌、41例乳腺良性病变和10例正常乳腺组织进行了细胞粘附分子CD_(15)检测。结果发现,CD_(15)。在乳腺癌和乳腺良性病变的阳性率分别为79.8％和58.3％,两者有显著差异性(P<0 01),10例正常乳腺组织仅4例呈CD_(15)弱阳性反应。CD_(15)表达与患者年龄和肿瘤大小无显著关系。CD_(15)表达阳性率在浸润性导管癌中显著高于单纯癌(P<0.05),组织学Ⅱ～Ⅲ级显著高于Ⅰ级者(P<0.05),临床Ⅲ一Ⅳ期显著高于Ⅰ期和Ⅱ期者(P<0.05),淋巴结转移阳性组显著高于阴性组(P<0.01)。在一组原发部位和淋巴结转移性乳腺癌配对标本中,CD_(15)表达无明显差异性。CD_(15)阳性的乳腺癌Cath-D和c-erbB-2的表达阳性率均显著高于CD_(15)阴性者(P<0.001)。结果提示,CD_(15)的表达与乳腺癌的发生发展、浸润转移及预后有密切关系。

Monocyte HLADR and Immune Dysregulation Index as Biomarkers for COVID-19 Severity and Mortality

Immune dysregulation in COVID-19 is the major causal factor associated with disease progression and mortality. Role of monocyte HLA-DR (mHLA-DR), neutrophil CD64 (nCD64) and Immune dysregulation index (IDI) were studied in COVID-19 patients for assessing severity and outcome. Results were compared with other laboratory parameters. Antibody bound per cell for mHLA-DR, nCD64 and IDI were measured in 100 COVID-19 patients by flow cytometry within 12 h of hospital admission. Thirty healthy controls (HC) were included. Clinical and laboratory parameters like C - reactive protein (CRP), Procalcitonin (PCT), Absolute Lymphocyte count (ALC), Absolute Neutrophil count (ANC) and Neutrophil to Lymphocyte ratio (NLR) were recorded. Patients were followed up until recovery with discharge or death. Parameters from 54 mild (MCOV-19), 46 severe (SCOV-19) and 30 HC were analysed. mHLA-DR revealed significant and graded down regulation in MCOV-19 and SCOV-19 as compared to HC whereas IDI was lowest in HC with increasing values in MCOV-19 and SCOV-19. For diagnostic discrimination of MCOV-19 and SCOV-19, IDI revealed highest AUC (0.99). All three immune parameters revealed significant difference between survivors (n = 78) and non-survivors (n = 22). mHLA-DR < 7010 and IDI > 12 had significant association with mortality. Four best performing parameters to identify patients with SCOV-19 at higher risk of mortality were IDI, NLR, ALC and PCT. mHLA-DR and IDI, in addition to NLR and ALC at admission and during hospital stay can be utilized for patient triaging, monitoring, early intervention, and mortality prediction. IDI reported for the first time in this study, appears most promising. Immune monitoring of ‘in hospital’ cases may provide optimized treatment options.Supplementary InformationThe online version contains supplementary material available at 10.1007/s12291-022-01087-z.
