    摘要: A method for genetically engineering cells to produce soluble and secretable Golgi processing enzymes instead of naturally occurring membrane-bound enzymes. Cells are genetically engineered to express glycosyltransferases which lack both a membrane anchor and a rThis invention was made with government support under Grant Contract Nos. GM-27904 and GM-11557 awarded by the National Institute of Health. The government has certain rights in this invention. The publications and other reference materials referred to herein to describe the background of the invention and to provide additional detail regarding its practice are hereby incorporated by reference. For convenience, the reference materials are numerically referenced and grouped in the appended bibliography.

    摘要: The invention provides methods for inhibiting immune responses by inhibiting the biosynthesis of the sialyl galactosides that are involved in immune responses. In particular, B lymphocyte-mediated immune responses are mediated by interfering with synthesis of &agr;2,6 sialylgalactosides, while T lymphocyte-mediated immune responses are inhibited by blocking synthesis of &agr;2,3 sialylgalactosides. The inhibition is accomplished by, for example, inhibiting the activity of a glycosyltransferase involved in synthesis of the respective sialyl galactoside.
