Hematopoietic effects of recombinant human interleukin - 3 and interleukin - 6

Regulation of interleukin-1beta and interleukin-1beta inhibitor release by human airway epithelial cells.

In asthma, human airway epithelial cells (HAECs) regulate the intensity of mucosal inflammation, in part, by releasing the pro-inflammatory cytokine interleukin (IL)-1beta. However, the IL-1beta inhibitors, IL-1 receptor antagonist (IL-1RA) and soluble IL-1 receptor type II (sIL-1RII), regulate IL-1beta bioactivity. In order to better understand the control of IL-1beta activity in the airway mu...

Optimization of Cloning Conditions for high-level Production of Recombinant Mouse Interleukin-2 in Escherichia coli

Backgrounds and objectives: Interleukin 2 (IL-2) secreted by activated CD4+ T cells  has been known as a major mediator in both  adaptive and native immune system  due to a board range of effects on  different cells in the immunity system (1-6). Methods: cDNA synthesis was performed using gene- specific primers designed by Gene Runner software after RNA extraction of mouse splenocytes. PCR pro...

The Effect of Mg2+ and Mn2+ on Over-Production of Interleukin-2 in Recombinant E.coli

In order to increase the productivity of human interleukin-2 (IL-2) as a model protein in the recombinant E.coliBL21 (DE3), the effect of magnesium acetate and manganese acetate was studied based on full factorial design experiments magnesium acetate and manganese acetate and their interaction exhibited an increasing effect on IL-2 expression level upto 25.24%, 16.80% and 23.30%, respective...

Limited proteolysis of recombinant human soluble interleukin-2 receptor. Identification of an interleukin-2 binding core.

Limited proteolysis of a recombinant, soluble form of the Tac protein, a human interleukin-2 receptor (rIL-2R), was performed using trypsin, Staphylococcus aureus V8 protease and proteinase K to study the structural requirements of interleukin-2 receptor (IL-2R) for interleukin-2 (IL-2) binding. Sensitive proteolytic sites were found to be clustered in the regions of the polypeptide encoded by ...
