  • Publication number: 20180105547
    Abstract: The inventors demonstrate that treatment of young, suckling mice with a glycolipid derived from Helicobacter pylori activates NKT cells in a CD1d-restricted fashion, and is protective against AHR in a model of allergen-induced asthma. The inventors further found that this protective effect can be transferred by NKT cells exposed to the glycolipid, and is associated with the expansion of a suppressive double-negative NKT cells and Foxp3+ TReg cells. The inventors also demonstrate herein that pretreatment of adult mice with a glycolipid derived from Helicobacter pylori partially suppresses airway hyperreactivity and inhibits BAL inflammation in an ozone-exposure model. Accordingly, provided herein are compositions and methods for the treatment and prevention of inflammatory diseases, such as asthma or autoimmune diseases, in a subject in need thereof.

  • Publication number: 20120295349
    Abstract: A mammal dedicated cell line is provided, which is a HepG2 hepatocellular carcinoma cell line (HepG2/NF-kB/Luc/sr39tk)1_18 obtained by co-transformation with NF-kB/Luc and NF-kB/sr39tk. Firstly, a successfully transformed pNF-kB/Luc HepG2 cell is obtained. Then, a dedicated cell line sensitive to TPA and MTX is generated by experimental screening Next, a plasmid construct carrying pNF-kB/sr39tk genome is introduced into the dedicated cell line by means of Superfect protocol. Finally, a HepG2 cell line co-expressing NF-kB/Luc and NF-kB/sr39tk is screened with G418 and ZEOCIN, and transformation result is confirmed by luminescence and radio activity. The (HepG2/NF-kB/Luc/sr39tk)1_18 obtained is suitable to screen drug for treating liver cancer and examine these cells by bioluminescence imaging and nuclear medicine imaging.

  • Patent number: 7928077
    Abstract: The present disclosure relates to synthetic alpha-galactosyl ceramide (?-GalCer) analogs, and their use as immunotherapies. In one aspect. a method of activating a cytokine response in a subject includes administering an effective amount of a compound to a subject, wherein the subject has an adaptive immune system that includes a population of cells, the population including at least one lymphocyte and at least one antigen-presenting cell, and wherein the compound is represented by the structure of formula 1: or a pharmaceutically acceptable salt thereof; forming a complex between the compound and the antigen-presenting cell, wherein the formation of the complex results in the activation of a receptor on the lymphocyte; and activating the lymphocyte to produce the cytokine response.

  • Publication number: 20080226546
    Abstract: This invention is to manufacture a kit for preparation of nano-targeted liposome drugs in combined chemotherapy and radionuclide therapy. It is a kit consisting of three components: (1) A 10 ml vial A which contains BMEDA, gluconate acetate, SnCl2. (2) A 10 ml vial B which contains DSPC, cholesterol, DSPE-PEG, and Doxorubicin(DXR) (or Daunorubicin, Vinolbine). (3) A 10 ml vial C which contains 188ReO4? (or 186ReO4?) solution. The procedure of using the kit is as follows: (1) Remove the contents of the 188ReO4? (or 186ReO4?) solution from vial C. (2) Inject the 188ReO4? (or 186ReO4?) solution into the vial A, and the mixtures react in appropriate temperature. (3) Remove the contents of the 188Re-BMEDA (or 186Re-BMEDA) solution from vial A.
