Interleukin 7 independent development of human B cells.

Interleukin 7 independent development of human B cells.

Mammalian hematopoietic stem cell (HSC) commitment and differentiation into lymphoid lineage cells proceed through a series of developmentally restricted progenitor compartments. A complete understanding of this process, and how it differs from HSC commitment and differentiation into cells of the myeloid/erythroid lineages, requires the development of model systems that support HSC commitment t...

Cloning and Expression of Recombinant Human Interleukin-7 in Chinese Hamster Ovary (CHO) Cells

Background: The critical role of interleukin-7 (IL-7) in homeostatic proliferation and T cell survival has made it a promising cytokine for the treatment of various clinical conditions, especially those associated with lymphopenia. Methods: In the present study we expressed recombinant human interleukin-7 (rhIL-7) in Chinese hamster ovary (CHO)-K1 cells. CHO-K1 cells were stably transfected ...

The roles of IL-2, IL-7, and IL15 Ligands in B Cells development

Abstract Background B cells play an important role in the immune system due to production of the immunoglobulin and secreting several cytokines. It has been shown that B cells produced successfully in the presence of stem cell factor (SCF) and Flt3 ligand (Flt3L). IL2, IL7, and IL15 cytokines as -common family have an essential cytokines may support either synergistically or in an additive m...

B 7 - Independent Inhibition of T Cells by CTLA - 41

Interleukin-7 influences the development of thymic dendritic cells.

Interleukin-7 (IL-7) has been shown to be a critical factor in B and T lymphopoiesis, and to influence the differentiation of myeloid cell lineages. In the present study we extend these results demonstrating that IL-7 also plays an important role in the development of thymic dendritic cells (DC). The addition of IL-7 to rat fetal thymus organ cultures (FTOC) resulted in a drastic increase in th...
