The present invention relates to the use of agents that inhibit the toxic effects of amyloid oligomers by increasing intracellular levels of phosphoinositol 4-phosphate (PI(4)P, or “PIP”) and / or phosphotidylinositol 4,5-biphosphate (PI(4,5)P2 or “PIP2”), the use of such agents for the treatment of neurodegenerative diseases, methods of treating neurodegenerative diseases by administration of agents which alter lipid metabolism, and methods of identifying agents which alter the association of presenilins with γ-secretase and lipid rafts.

The present invention relates to the application of human recombined protein PDCD5 in preparing tumor chemotherapy temoporfin. Human recombined protein PDCD5 is non-virus intracellular transfer protein, which enters into cells through lipid raft / caveolae-dependent phagocytosis; PDCD5 can promote the death of programmed cells; the enter of the exogenous human recombined protein PDCD5 into cells can strengthen the sensitivity of various tumor cells to various chemotherapeutic drugs and promote the death of tumor cells caused by chemotherapeutic drugs.

A biological composition has a mixture of mechanically selected allogeneic biologic material derived from placental tissue. The mixture has non-whole cellular components including vesicular components and active and inactive components of biological activity, cell fragments, cellular excretions, cellular derivatives, and extracellular components. The mixture including non-whole cell fractions including one or more of exosomes, transcriptosomes, proteasomes, membrane rafts, lipid rafts. The mixture is compatible with biologic function.

Two-photon dyes for real-time imaging of lipid rafts are provided. The two-photon dyes emit fluorescence with high intensity in the environments of cell membranes and can be used to clearly discriminate the hydrophobic and hydrophilic domains of the cell membranes. Therefore, the use of the two-photon dyes enables satisfactory imaging of actual lipid raft domains. In addition, since the two-photon dyes show no cytotoxicity, they can be suitably used in bioimaging applications, for example, real-time imaging of lipid rafts over a long period of time.

The present invention relates to the discovery of antibodies able to modulate (prevent or favour) conversion of PrPc to PrPSc and to their antigens. Depending on the nature of the antibodies (antagonistic or agonistic), their respective antigens are either conversion factors or inhibitors of prion replication.

The present invention discloses methods of using endothelial membrane protein 2 (EMP2) as a biomarker for stratification of endometrial premalignancy, diagnosing, staging and imaging of endometrial neoplasia. Further, methods for identifying pharmaceutical / therapeutic modalities are described, including compositions which modulate glycolipid-enriched lipid raft microdomains (GEMs).

The invention discloses a single fluorescent probe for clearly distinguishing a cell membrane-lipid raft microdomain from a non-lipid-raft microdomain by using two fluorescence colors in a real-time in-situ manner and simultaneously imaging the microdomains. The fluorescent probe is a compound with a structure shown as a formula (I), wherein R1 expresses 2-ethoxyethyl, aminoalkyl, hydroxyalkyl or alkyl; R2 and R3 express alkyl. The invention also discloses application of the fluorescent probe in marking the lipid raft microdomain and the non-lipid-raft microdomain on a cell membrane of a living cell by using red and green fluorescence colors in the real-time in-situ manner. The probe can mark the lipid raft microdomain by using red fluorescence, and marks the non-lipid-raft microdomain by using green fluorescence at the same time, thereby realizing simultaneous imaging of the two microdomains. Compared with a current commonly-used similar probe laurdan, the probe disclosed by the invention has the characteristics that spectrum difference of two microdomains is greater, so that clear distinguishing and simultaneous imaging of the two microdomains are realized; besides, the internal problems is improved, so the probe is simpler and more convenient to operate during application and is broad in commercial application prospect.
