AI Article Synopsis

  • A study examined negative cell signaling in different types of asthma, involving 171 participants, including patients with allergic asthma (AA), non-allergic asthma (NAA), and healthy individuals.
  • Results showed that AA patients had greater changes in expression of SOCS1, SOCS3, and SOCS5 compared to NAA, which only exhibited notable changes in SOCS3.
  • The study concluded that variations in cytokine signaling regulation are complex and depend on different pathways influenced by SOCS genes in both types of asthma.

Article Abstract

Aim: To conduct a comprehensive study of the components of negative cell signaling regulation in different types of asthma.

Subjects And Methods: A total of 171 people, including 80 patients with allergic asthma (AA), 60 patients with non-allergic asthma (NAA), and 31 apparently healthy individuals, were examined. SOCS5 mRNA expression was assessed by reverse-transcription polymerase chain reaction. The expression of SOCS1 and SOCS3 proteins was investigated by immunoblotting. The concentration of total serum IgE was determined by enzyme immunoassay; the level of cytokines was measured according to the standard protocol using a Bio-Plex fluorometer.

Results: The findings show that the patients with AA generally display more marked changes in the expression of all three investigated SOCSes (SOCS1, SOCS3, and SOCS5) at baseline and when interleukin 4 (IL-4) acts. In NAA, there are pronounced changes in the expression of SOCS3 only and, to a lesser extent, SOCS5. The results of investigating the concentrations of IL-4 in the examined groups demonstrate its significant decrease in the AA group, whereas in the NAA group, it is similar to those in healthy individuals. On the contrary, IL-10 concentrations in AA tend towards those in the control group, but much exceed in NAA.

Conclusion: The findings allow one to consider the complexity of regulatory disorders arising at various levels of cell signaling in the context of the multifunctional nature of the molecules from the family of negative regulators of transcription of the SOCS1, SOCS3, and SOCS5 genes, which provide the comprehensive control of cytokine signaling simultaneously in different signal pathways.

Diabetes mellitus type 2 (DMT2) promotes Achilles tendon (AS) degeneration and exercise could modulate features of DMT2. Hence, this study investigated whether tenocytes of non DMT2 and DMT2 rats respond differently to normo- (NG) and hyperglycemic (HG) conditions in the presence of tumor necrosis factor (TNF)α or cyclic stretch. AS tenocytes, isolated from DMT2 (fa/fa) or non DMT2 (lean, fa/+) adult Zucker Diabetic Fatty (ZDF) rats, were treated with 10 ng/mL TNFα either under NG or HG conditions (1 g/L vs.

Background: Polymorphonuclear neutrophils (PMN) activation by monosodium urate crystals (MSU) is crucial to acute gouty arthritis and subsequent spontaneous remission within 7-10 days. Activated PMNs release neutrophil extracellular traps (NETs) that entrap MSU crystals, forming NET-MSU aggregates. Whether NET-MSU aggregates contribute to the resolution of acute inflammation remains to be elucidated.

ZNF350 gene polymorphisms promote the response to Peg-IFNα therapy through JAK-STAT signaling pathway in patients with chronic hepatitis B.

Department of Laboratory Medicine, Fujian Key Laboratory of Laboratory Medicine, Gene Diagnosis Research Center, Fujian Clinical Research Center for Clinical Immunology Laboratory Test, The First Affiliated Hospital, Fujian Medical University, Fuzhou, China.

Background: The varying individual responses to Pegylated interferon-α (Peg-IFNα) in patients with chronic hepatitis B (CHB) pose significant hurdles in treatment optimization, and the underlying mechanisms remain unclear.

Objective: We aimed to identify genetic polymorphisms influencing the efficacy of Peg-IFNα in patients with HBeAg-positive CHB, with the goal to predict Peg-IFNα response before treatment.

Methods: We employed an Asian Screening Array analysis involving 124 HBeAg-positive CHB patients treated with Peg-IFNα.

Relapsing-remitting multiple sclerosis is associated with changes in Jak/STAT pathways in immune cells, but the influence of disease-modifying drugs on these pathways is poorly understood. The aim of this study was to evaluate the impact of first-line disease-modifying drugs used in treatment of RRMS on expression of the STAT pathway and T-cell-related genes in the blood and on serum concentrations of sgp130 and TGF-β1 in women, as well as on the level of phosphorylated STAT3 and STAT5 proteins in T cells of untreated patients and heathy controls. Expression of STAT1, STAT3, STAT5A, STAT5B, SOCS1, SOCS3, FOXP3, IKZF2, RORC and ICOS genes in the blood of untreated RRMS patients, in the blood of patients treated with interferon-β, glatiramer acetate, dimethyl fumarate or teriflunomide and in the blood of healthy controls was evaluated using droplet digital PCR.

Background: Previous studies have reported that STAT1 (Signal Transducer and Activator of Transcription 1) is associated with multiple tumor progression. This study aimed to investigate the role and related mechanisms of STAT1 in bladder cancer.

Methods: STAT1 expression in bladder cancer tissues and human bladder cancer cell lines was assessed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR).
