The MaxDiscovery™ Human IL-11 ELISA Test Kit is designed for quantitative determination of the concentration of human IL-11 in serum, plasma, and cell culture supernatant. Human interleukin 11 (IL-11), also known as adipogenesis inhibitory factor (AGIF) and oprelvekin, is a highly conserved 19 kDa protein of 178 amino acids after cleavage of the first 21 amino acid signal peptide. IL-11 is thermally stable and contains neither cysteine residues nor N-glycosylation sites. IL-11 is a member of the gp130 family of cytokines. These cytokines drive the assembly of multi-subunit receptor complexes containing at least one gp130. IL-11 exerts biological activity through IL-11 receptor by utilizing the gp130 molecule as the signaling component of its receptor. Many cell and tissue types throughout the body, such as CNS, thymus, lung, bone, connective tissues, uterus, skin, and testis, can produce IL-11 depending on the local environment of the cell or tissue. IL-11 promotes primary and secondary immune responses in vitro and in vivo and modulates antigen-specific antibody reactions. IL-11 has activity in bone metabolism and activity in protection and restoration of the gastrointestinal mucosa. Human endometrial stromal cells produce biologically active IL-11, which promotes progesterone-induced decidualization. Therefore, the IL-11 has both paracrine and autocrine actions on human endometrial stromal cells and plays an important role in preparing the human endometrium for implantation. Reports indicate that abnormal IL-11 levels in serum or plasma is related to immune thrombocytopenia, rheumatoid arthritis, and urogenital infection. Immunoreactive IL-11 has also been linked to aseptic loosening of total hip replacement implants. The production of IL-11 is elevated in lesional skin organ cultures of patients with active plaque-type psoriasis as compared with non-lesional and normal skin.
Charting Kidney Cancer Metabolism Changes in cell metabolism are increasingly recognized as an important way tumors develop and progress, yet these changes are hard to measure and interpret. A new tool designed by MSK scientists allows users to identify metabolic changes in kidney cancer tumors that may one day be targets for therapy.Insights into the Function of the Main Class of Drug Targets About thirty percent of all medical drugs such as beta-blockers or antidepressants interact with certain types of cell surface proteins called G protein coupled receptors.Visualizing a Cancer Drug Target at Atomic Resolution Using cryo-electron microscopy, researchers were able to view, in atomic detail, the binding of a potential small molecule drug to a key protein in cancer cells.Honey’s Potential to Save Lives The healing powers of honey have been known for thousands of years. 3-D Printed Lifelike Liver Tissue for Drug Screening A team led by engineers at the University of California, San Diego has 3D-printed a tissue that closely mimics the human liver's sophisticated structure and function. The new model could be used for patient-specific drug screening and disease modeling. Cytoskeleton Crew Findings confirm sugar's role in helping cancers survive by changing cellular architecture.Biomarker for Recurring HPV-Linked Oropharyngeal Cancers A look-back analysis of HPV infection antibodies in patients treated for oropharyngeal (mouth and throat) cancers linked to HPV infection suggests at least one of the antibodies could be useful in identifying those at risk for a recurrence of the cancer, say scientists at the Johns Hopkins University. Valvena, GSK Sign New R&D Collaboration Valneva to supply process development services for EB66® -based Influenza vaccines. Light Signals from Living Cells Fluorescent protein markers delivered under high pressure.Cellular 'Relief Valve' A team led by scientists at The Scripps Research Institute (TSRI) has solved a long-standing mystery in cell biology by showing essentially how a key “relief-valve” in cells does its job.
