Objective: To study the expression of T-bet, GATA-3 and FOXP3 mRNA in asthmatic peripheral blood mononuclear cells (PBMC) before and after stimulation by Dermatophagoides farinae antigen (Df), and the relationship among the three transcription factors.
Methods: Twenty-five patients of asthma and 15 healthy controls were included. The mRNA levels of T-bet, GATA-3, and FOXP3 in PBMC before and after Df stimulation were detected by semiquantitative reverse transcription-polymerase chair reaction (RT-PCR).
Results: There was no statistical difference (t = 0.78, 0.38 respectively, all P > 0.05) in the levels of T-bet and FOXP3 mRNA between the patients (0.3 +/- 0.4, 0.42 +/- 0.24 respectively) and the healthy controls (0.4 +/- 0.3, 0.39 +/- 0.37 respectively). However, GATA-3 mRNA was statistically different (t = 2.27, P < 0.05) between the patients (1.0 +/- 0.3) and the healthy controls (0.8 +/- 0.3). After the stimulation of PBMC by Df, the levels of T-bet, GATA-3 and FOXP3 mRNA showed statistical difference (t = 2.30, 3.79, 2.08 respectively, P < 0.05, < 0.01, < 0.05 respectively) between the patients (0.33 +/- 0.39, 1.58 +/- 1.44, 0.11 +/- 0.32 respectively) and the healthy controls (0.03 +/- 0.40, 0.11 +/- 0.53, 0.43 +/- 0.66 respectively). The FOXP3 mRNA level in the asthmatics was negatively correlated with T-bet and GATA-3 mRNA (r = -0.46, P < 0.05, r = -0.62, P < 0.01 respectively).
Conclusions: There are a predominant expression of GATA-3 and T-bet, but a decreased expression of FOXP3 in Df-stimulated PBMCs from patients with asthma.

Neuro-Behçet's disease (NBD) is a more severe but rare symptom of Behçet's disease (BD), which is mainly divided into parenchymal NBD (p-NBD) involving brain stem, spinal cord, and cerebral cortex. Non-p-NBD manifests as intracranial aneurysm, cerebral venous thrombosis, peripheral nervous system injuries, and mixed parenchymal and non-parenchymal disease. P-NBD is pathologically characterized by perivasculitis presenting with cerebrospinal fluid (CSF) pleocytosis, elevated total protein, and central nervous system (CNS) infiltration of macrophages and neutrophils, which are subdivided into acute and chronic progressive stages according to relapsing-remitting courses and responses to steroids.

Background: Phospholipase D2 (PLD2) enzymes are expressed on the cytoplasmic membrane of bacteria, fungi, plants, and animals. Recently, extensive research has linked PLD2 to the chronic inflammatory activity of cells. Allergic asthma is a chronic airway inflammation disease.

Tumor inflammation, as one of the hallmarks of cancer, has been the target for anti-cancer treatments. Celecoxib is a selective inhibitor of the enzyme cycloxygenase-2 (COX-2) and inhibits the production of PGE2, which is an important mediator of tumor inflammation produced by cancer cells and cells of the tumor microenvironment. In this study, we aimed at inhibiting COX-2 using celecoxib, expressed in cancer-associated fibroblast (CAF)-like cells isolated from breast cancer and evaluated the alterations in their cytokine profile and gene expression.

Hydrolyzed milk protein is a mainstream way to address this difficulty. The aim of this study was to assess the effect of differences in whey protein concentrate (WPC) source and the degree of hydrolysis on blocking allergy and to analyze the possible mechanisms by which hydrolyzed infant formula (IF) blocks allergy through colony-metabolism-immunity response.

Background: Currently, the use of probiotics to treat inflammatory bowel diseases (IBD) is widely accepted because of their gut microbiota modulation capabilities and anti-inflammatory potential.
Objective: The aim of this study is to examine the immunomodulatory outcomes of probiotics and sulfasalazine in the acetic acid-induced colitis murine model.
Methods: The animals were randomly assigned to one of the seven groups.
