    摘要： Beams of coherent microwaves or other frequencies of highly directional electromagnetic radiation are passed through the living human body to detect and provide a quantitative analysis of functional activity in the central nervous system and/or in muscle tissue such as that of the heart. Organs to be analyzed are situated in the space of an electrostatic field of oscillating intensity. The directional beam is passed through a body organ situated in this way. The method is of use in detecting degenerative subcortical disease in the brain (e.g., Sulphatide Lipidosis), tissue damage to nerve fibers due to toxic chemicals, and other types of tissue-based functional abnormality. Functional condition of brain and heart generally can be readily analyzed without exposure to ionizing radiation.

    摘要： The present invention provides liposomal compositions for inducing immune tolerance. The compounds typically comprise a liposome displaying a specific antigen and also a binding moiety for a sialic acid binding Ig-like lectin (Siglec) expressed on B cells. The invention also provides methods for inducing tolerance to a protein or polypeptide antigen (e.g., a protein antigen) in a subject. The methods involve administering to the subject a pharmaceutical composition that co-presents both the antigen and a glycan ligand for a Siglec expressed on B lymphocytes.

    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.

    摘要： The present invention provides liposome targeting compounds for targeting cells expressing sialic acid binding Ig-like lectin (Siglec). The liposome compounds typically comprise a binding moiety that is a glycan ligand of the Siglec on the target cell. The liposome compounds also incorporate or encapsulate a biological agent (e.g., an antigen or a therapeutic agent) that can be delivered to the target cell to modulate or kill the target cell. The invention also provides methods of using the liposome targeting compounds for targeted delivery of antigen and for modulating immune cells or immune responses.
