Imbalance of Th17 and Treg in peripheral blood mononuclear cells of active tuberculosis patients BJID
Luo,Jie; Zhang,Mingxu; Yan,Baosong; Zhang,Kejun; Chen,Ming; Deng,Shaoli.
Abstract Objective: Maintaining a right balance between Th17 and Treg might be critical to the immunopathogenesis of active tuberculosis (TB). This study aimed to assess whether the Th17/Treg balance is altered in active TB patients. Methods: 250 study subjects (90 active TB patients, 80 latent TB subjects, and 80 healthy controls) were recruited for the study. The expression of Th17 and Treg in peripheral blood mononuclear cells (PBMCs) in the 250 subjects was investigated by flow cytometry. Plasma levels of cytokines IL-17 and IL-10, which are related to Th17 and Treg, respectively, were determined by ELISA. Results: The percentages of Th17 and Treg in PBMCs from active TB patients were significantly higher than those from latent TB or control groups...

Study of the relationship between human MIF level, MIF-794CATT5-8 microsatellite polymorphism, and susceptibility of tuberculosis in southwest China BJID
Li,Yanlin; Zeng,Zhaofang; Deng,Shaoli.
OBJECTIVE: To study the human migration inhibitory factor (MIF) level in tuberculosis (TB) patients, and the relationship between MIF-794CATT microsatellite polymorphism and susceptibility of TB in Southwest China. METHODS: TB patients (n = 151) and healthy unrelated controls (n = 149) were recruited for this study. Genomic DNA was extracted, and then amplified by polymerase chain reaction (PCR). MIF-794CATT5-8 microsatellite polymorphism was genotyped by DNA sequencing. MIF level was detected by ELISA. RESULTS: In the TB group, the repeat number of 7/7 and 7/8 (17.89%) was significantly higher than that of the control group (8.05%), and the serum MIF level was also much higher than that of the healthy controls (705.21 ± 67.98 vs. 355.31 ± 57.29 pg/mL, p...
