Soluble interleukin-2 receptor, interleukin-2 and interleukin-4 in sera and supernatants from patients with progressive systemic sclerosis.

We studied the sera of patients with progressive systemic sclerosis (PSS) for elevated levels of soluble interleukin-2 receptor (sIL-2R), interleukin-2 (IL-2) and interleukin-4 (IL-4). We also measured IL-2, IL-4 and B cell growth factor (BCGF) activity in supernatants of peripheral blood mononuclear cells from the same patients. The finding of elevated serum sIL-2R and IL-2, and the increased levels of IL-2, IL-4 and BCGF activity in culture supernatants indicates that T lymphocyte hyperactivity likely play a major role in PSS. The failure to detect under our experimental conditions a direct proliferative effect of recombinant IL-2 on enriched normal B cells might suggest that IL-4 is the cytokine mainly responsible of the BCGF activity recovered in PSS supernatants.     

脑囊虫病患者粘附分子和细胞因子水平检测

本文检测了30例未经治疗的脑囊虫病患者血清中可溶性细胞粘附分子(sICAM)、白细胞介素8(IL-8)、可溶性白细胞介素2受体(sIL-2R)以及患者外周血单个核细胞(PBMC)体外诱导IL-2、IFN-γ及TNF-α的活性,同时也检测了CD11a、CD11b和CD18在患者PBMC表面的表达,以30例正常人作对照,探讨了脑囊虫病人粘附分子、细胞因子水平的变化及在免疫调节中的作用.结果显示脑囊虫病患者血清中sICAM-I水平及患者PBMC体外诱导IL-2、IFN-γ水平显著低于正常对照组,患者血清中IL-8、sIL-2R及患者PBMC体外诱导TNF-α水平明显高于正常对照组,患者组的CD11b阳性细胞百分比显著高于对照组,但是患者PBMC表面CD11a的表达量比对照组低,而CD18的表达在两组间无显著性差异.     

呼吸道合胞病毒下呼吸道感染对机体细胞免疫的影响

为研究呼吸道合胞病毒（ＲＳＶ）急性下呼吸道感染（ＡＬＲＩ）的细胞免疫变化，对２５例病儿外周血白细胞介素２（ＩＬ－２）和可溶性白细胞介素２受体（ｓＩＬ－２Ｒ）水平、Ｔ细胞白细胞介素２受体（ＩＬ－２Ｒ）表达率和Ｔ细胞亚群百分率进行检测。结果显示，急性期病儿外周血ＩＬ－２水平明显低于恢复期和正常对照组，Ｔ细胞ＩＬ－２Ｒ表达率亦明显降低，而ｓＩＬ－２Ｒ水平却显著增高。急性期病儿ＩＬ－２水平与Ｔ细胞ＩＬ－２Ｒ表达率和ＣＤ＋４细胞百分率呈正相关，与ｓＩＬ－２Ｒ水平和ＣＤ＋８细胞百分率呈负相关；ｓＩＬ－２Ｒ水平与Ｔ细胞ＩＬ－２Ｒ表达率呈负相关，与临床严重程度呈正相关。上述各项免疫指标异常均提示ＲＳＶ感染时机体存在细胞免疫功能紊乱。

Soluble interleukin-2 receptor and disease activity in Crohn's disease.

An ELISA was used to measure concentrations of soluble interleukin-2 receptor (sIL-2R) alpha chain in the sera of patients with Crohn's disease. In a group of 56 patients, serum concentrations of sIL-2R were significantly raised in patients with active disease compared with patients with inactive disease and age-matched control populations. There was a significant correlation between serum sIL-2R concentration and disease activity as assessed by the Harvey-Bradshaw index (r = +0.60; P less than 0.001) and laboratory measurements of disease activity including C-reactive protein (r = +0.79; P less than 0.001), ESR (r = +0.64; P less than 0.001) and platelet count (r = +0.533; P less than 0.001). We also found a negative correlation between sIL-2R levels and serum albumin (r = -0.66; P less than 0.001). In longitudinal studies, changes in the concentration of serum sIL-2R reflected the changes in disease activity. Soluble IL-2R, therefore, offers a new measure of disease activity in Crohn's disease with a potential advantage over other laboratory parameters currently available in that it may reflect more accurately the underlying immunopathogenic process.     

Soluble interleukin-6 receptor (sIL-6R) in cerebrospinal fluid of patients with inflammatory and non inflammatory neurological diseases

IL-6 acts on target cells via the ligand-binding protein interleukin-6 receptor (IL-6R) and the affinity-converting and signal-transducing glycoprotein 130 (gp130). Soluble interleukin-6 receptor (sIL-6R) has an agonistic role because the soluble complex (IL-6/sIL-6R) can activate cells that do not express IL-6R and an antagonistic role as it enhances the inhibitory activity of sgp130. Soluble forms of both receptors, sIL-6R and sgp130, regulate the action of IL-6. sIL-6R was measured by a sensitive enzyme-linked immunosorbent assay in paired sera and cerebrospinal fluid (CSF) from 46 patients with inflammatory neurological diseases (IND), 45 patients with relapsing-remitting multiple sclerosis (RR-MS), 13 patients with primary progressive multiple sclerosis (PP-MS), 17 patients with other non inflammatory neurological diseases (NIND) and 13 mentally healthy individuals--healthy controls (HC). Patients with RR-MS had CSF sIL-6R levels comparable to those from patients with IND, but higher than patients with NIND and HC. A positive correlation between the CSF/serum albumin (QAlb) and CSF sIL-6R levels was observed in IND but not in RR-MS patients indicating that CSF sIL-6R levels in IND patients could be influenced by serum sIL-6R and blood brain barrier (BBB) permeability properties. RR-MS patients had higher values of [CSF/serum sIL-6R:CSF/serum albumin] (sIL-6R index) than IND patients suggesting that in multiple sclerosis (MS), the increase in CSF sIL-6R could be due to intrathecal synthesis of sIL-6R. The finding of increased CSF sIL-6R concentrations (>979 pg/ml) with sIL-6R index (>4.66), in correlation with positive oligoclonal bands in RR-MS patients, suggests that values of sIL-6R index > 4.66 indicate intrathecal increase of sIL-6R and might be used as an indicator of neuroimmunoregulatory and inflammatory processes in the central nervous system (CNS).

Cytokines serum levels as the markers of thyroid activation in Graves'' disease

In order to examine which cytokine could be used as a marker of the biological effect of thyroid hormones or anti-thyroid antibodies in Graves' disease (GD) patients, we simultaneously evaluated the concentrations of TSH, free thyroid hormones (fT₃ and fT₄), anti-thyroid antibodies (anti-TPO and anti-TG) and a group of cytokines: interleukin-2 (IL-2), tumour necrosis factor (TNF), interleukin-6 (IL-6) and their soluble receptors (sIL-2R, sTNFR, sIL-6R) as well as interleukin-10 (IL-10) in eight GD females and nine normal controls. We found that serum sIL-2R concentrations of GD patients had only the tendency to be higher versus controls, but strong positive correlations between fT₃ and fT₄ and sIL-2R in peripheral blood of GD subjects were revealed. We showed that sIL-2R was the best cytokine marker, showing very good correlation with the endocrine status of GD patients.
