Interleukin 7 Plays a Role in T Lymphocyte Apoptosis Inhibition Driven by Mesenchymal Stem Cell without Favoring Proliferation and Cytokines Secretion
Since 2004, when a case report describing the use of human mesenchymal stem cells (hMSCs) infusion as a therapy for GVHD after bone marrow transplantation, a new perspective in MSC function emerged. Since then hMSCs immunomodulatory potential became the target of several studies. Although great progress has been made in our understanding of hMSCs, their effect on T cell remains obscure. Our stu...
متن کاملNitric oxide plays a critical role in suppression of T-cell proliferation by mesenchymal stem cells.
The molecular mechanisms by which mesenchymal stem cells (MSCs) suppress T-cell proliferation are poorly understood, and whether a soluble factor plays a major role remains controversial. Here we demonstrate that the T-cell-receptor complex is not a target for the suppression, suggesting that downstream signals mediate the suppression. We found that Stat5 phosphorylation in T cells is suppresse...
متن کاملRegulation of interleukin 2-driven T-lymphocyte proliferation by prolactin.
The requirement for prolactin in interleukin 2-driven T-cell proliferation was evaluated. Addition of an anti-prolactin antiserum resulted in the specific inhibition of T-cell proliferation in a time- and dose-dependent manner. Synthesis of prolactin and its mRNA, however, did not occur during interleukin 2 stimulation. Instead, previously internalized prolactin, presumably from fetal bovine se...
متن کاملMir-55 inhibition can reduce cell proliferation and induce apoptosis in Jurkat (Acute T cell Leukemia) cell line
Background MicroRNAs are small and non-coding RNA molecules with approximately 22 nt in length that cause inhibition of translation or degradation of mRNA. MiR-155 is a kind of molecule with different functions, such as its role in proliferation, apoptosis, inflammation, differentiation, and immunity. One of its best known functions is apoptosis that affects on caspase-3 activity. The main aim...
متن کاملInterleukin-7 Links T Lymphocyte and Intestinal Epithelial Cell Homeostasis
Interleukin-7 (IL-7) is a major survival factor for mature T cells. Therefore, the degree of IL-7 availability determines the size of the peripheral T cell pool and regulates T cell homeostasis. Here we provide evidence that IL-7 also regulates the homeostasis of intestinal epithelial cells (IEC), colon function and the composition of the commensal microflora. In the colon of T cell-deficient, ...
