摘要:
T cell responses are often diminished in humans with a compromised immune system. We have developed a method to isolate, stimulate and expand naïve cytotoxic T lymphocyte precursors (CTLp) to antigen-specific effectors, capable of lysing tumor cells in vivo. This ex vivo protocol produces fully functional effectors. Artificial antigen presenting cells (AAPCs; Drosophila melanogaster) transfected with human HLA class I and defined accessory molecules, are used to stimulate CD8+ T cells from both normal donors and cancer patients. The class I molecules expressed to a high density on the surface of the Drosophila cells are empty, allowing for efficient loading of multiple peptides that results in the generation of polyclonal responses recognizing tumor cells endogenously expressing the specific peptides. The responses generated are robust, antigen-specific and reproducible if the peptide epitope is a defined immunogen. This artificial antigen expression system can be adapted to treat most cancers in a significant majority of the population.

摘要:
DNAs encoding the human histamine H3 receptor have been cloned and characterized. The recombinant protein is capable of forming biologically active histamine H3 receptor protein. The cDNAs have been expressed in recombinant host cells which produce active recombinant protein. The recombinant protein is also purified from the recombinant host cells. In addition, the recombinant host cells are utilized to establish a method for identifying modulators of the receptor activity, and receptor modulators are identified.
摘要:
This invention is directed to a method for preventing or treating psychotic disorders comprising administering to a subject in need thereof a therapeutically effective amount of a compound selected from the group consisting of formula (I) and formula (II) wherein phenyl is substituted at X with one to five halogen atoms selected from the group consisting of fluorine, chlorine, bromine and iodine; and, R1, R2, R3, R4, R5 and R6 are independently selected from the group consisting of hydrogen and C1-C4 alkyl; wherein C1-C4 alkyl is optionally substituted with phenyl (wherein phenyl is optionally substituted with substituents independently selected from the group consisting of halogen, C1-C4 alkyl, C1-C4 alkoxy, amino, nitro and cyano).
