Human soluble interleukin-7 receptor (sIL7R)α circulates in high molar excess compared with IL-7, but its biology remains unclear. We demonstrate that sIL7Rα has moderate affinity for IL-7 but does not bind thymic stromal lymphopoietin. Functionally, sIL7Rα competes with cell-associated IL-7 receptor to diminish excessive IL-7 consumption and, thus, enhances the bioactivity of IL-7 when the cyt...

Optimal CD4+ T cell recovery after initiating combination antiretroviral treatment (cART) in HIV infection reduces risk of morbidity and mortality. T-allele homozygosity ('TT') in the single nucleotide polymorphism, rs6897932(C/T), in the IL-7 receptor α (IL-7RA) is associated with faster CD4+ T cell recovery after cART initiation compared to C-allele homozygosity in rs6897932 ('CC'). However, ...

Using monoclonal antibodies Ta1 and CD25 (interleukin-2 receptor: I-2R) and flow cytometry, the levels of activated lymphocytes in the peripheral blood of 50 patients with multiple sclerosis (16 relapsing inactive; 14 relapsing active; 20 chronic progressive) and 20 normal subjects were investigated. No significant differences were observed in the percentage or absolute numbers of Ta1 and IL-2R...

BACKGROUND Multiple sclerosis (MS) is a chronic inflammatory demyelinating and neurodegenerative disease of central nervous system with unknown causes. Etiology of MS involves both genetic and environment factors. The interleukin 7 receptor (IL7R) gene is a promising candidate for MS, because its involvement in the autoimmunity, regulation of the T-cell homeostasis, proliferation, and anti-apop...

Glutamate excitotoxicity is implicated in the progressive loss of oligodendrocytes in multiple sclerosis, but how glutamate metabolism is dysregulated in the disease remains unclear. Because there is microglia activation in all stages of multiple sclerosis, we determined whether a microglia product, interleukin-1beta, could provide the mechanism for glutamate excitotoxicity. We found that where...

conclusions our study suggests that the personality traits of patients with ms and healthy individuals are not significantly different. patients with ms are likely to use the same coping strategies as healthy individuals, except in the subscale of distancing. results no significant differences in personality characteristics were observed between patients and healthy controls (all p > 0.05). onl...
