Bulk quantities of proteins are available. Please contact us for pricing.
Interleukin-2 (IL-2) is a cytokine produced by T-helper cells in response to antigenic or mitogenic stimulation. It is required for T-cell proliferation and other activities crucial to the regulation of the immune response. IL-2 was discovered to be a member of a family of cytokines, which also includes IL-4, IL-7, IL-9, IL-15 and IL-21. IL-2 signals through a receptor complex consisting of IL-2 specific IL-2 receptor alpha (CD25), IL-2 receptor beta (CD122) and a common gamma chain (γc). All members of this family use the common gamma chain as part of their signaling complex.

Chlamydia psittaci PmpD-N Exacerbated Chicken Macrophage Function by Triggering Th2 Polarization and the TLR2/MyD88/NF-κB Signaling Pathway

Int J Mol Sci. 2020 Mar 15;21(6):2003. doi: 10.3390/ijms21062003.
Applications: Measurement of chicken IL-2, IL-6, IL-10, IL-12, and IFN-γ in cell culture supernatants by ELISA
Abstract
The polymorphic membrane protein D (PmpD) is a highly conserved outer membrane protein which plays an important role in pathogenesis during Chlamydia psittaci infection. In this study, we evaluated the ability of the N-terminus of PmpD (PmpD-N) to modulate the functions of chicken macrophages and the signaling pathway(s) involved in PmpD-N-induced Toll-like receptors (TLRs), as well as interleukin (IL)-6 and IL-10 cytokine secretions. Thus, HD11 macrophages were treated with exogenous and intracellular PmpD-N of C. psittaci. The chlamydial growth was evaluated by enumeration of chlamydial loads in the infected macrophages. The phagocytic function of macrophages following PmpD-N treatment was detected by fluorescein-labeled Escherichia coli (E. coli). The concentration of nitric oxide (NO) secreted by HD11 macrophages was measured by the amount of NO2- in the culture supernatant using the Griess method. The cytokine secretions were assessed using multiplex cytokine ELISA kits. Expression levels of TLRs, myeloid differentiation factor 88 (MyD88), and nuclear factor kappa B (NF-κB) were analyzed by a Western blotting assay, as well as a luciferase assay, while NF-κB p65 nuclear translocation was assessed by confocal microscopy. The nuclear translocation of the transcription factor NF-κB was confirmed by evaluating its ability to combine with the corresponding promoter using the electrophoretic mobility shift assay (EMSA). After treatment with exogenous or endogenous PmpD-N, chlamydial loads and phagocytic functions were reduced significantly compared with those of the plasmid vector group, while NO secretions were reduced significantly compared with those of the lipopolysaccharide (LPS) treatment. Stimulation of HD11 cells with PmpD-N provoked the secretion of the Th2 cytokines, IL-6, and IL-10 and upregulated the expression of TLR2, TLR4, MyD88, and NF-κB. Furthermore, inhibition of TLR2, MyD88, and NF-κB in HD11 cells significantly decreased IL-6 and IL-10 cytokine levels, while NO production and phagocytosis increased significantly, strongly suggesting their involvement in PmpD-N-induced Th2 cytokine secretion and macrophage dysfunction. Our data indicate that C. psittaci PmpD-N inhibited macrophage functions by activating the Th2 immune response and the TLR2/MyD88/NF-κB signaling pathway.
Vitamin D-1a-hydroxylase and vitamin D-24-hydroxylase mRNA studies in chickens

Poult. Sci., Aug 2012; 91: 1819 - 1824.
Applications: Cell Culture Stimulation
A series of experiments were conducted to study the basal amounts of vitamin D-1α-hydroxylase and vitamin D-24-hydroxylase mRNA amounts in different organs and the effect of immune stimulation on 1α- and 24-hydroxylase mRNA amounts in chickens. At day of hatch, kidneys had an approximately 66-fold higher amount of 1α-hydroxylase and 550-fold higher amount of 24-hydroxylase mRNA, thigh and breast muscles had an approximately 20-fold higher amount of 1α-hydroxylase mRNA, and the thymus had an approximately 41-fold higher amount of 24-hydroxylase mRNA than the liver. An in vivo LPS injection did not alter the amount of 1α-hydroxylase mRNA in the breast muscle (P=0.60) or in the kidneys (P=0.39). An in vivo LPS injection decreased (P=0.01) the amount of 24-hydroxylase mRNA in the breast muscle at 3 d post-LPS injection. An in vivo LPS injection increased (P=0.01) the amount of 24-hydroxylase mRNA in the kidneys at 2, 3, and 6 d post-LPS injection. An in vitro stimulation altered amounts of 1α- (P=0.01) and 24-hydroxylase (P=0.04) mRNA in CD4+ cells. In conclusion, the distribution of 1α- and 24-hydroxylase mRNA amounts was similar to mammals, and an immune stimulation altered the amounts of 1α- and 24-hydroxylase mRNA in chickens.
