353 results about "Transmembrane protein" patented technology

A transmembrane protein (TP) is a type of integral membrane protein that spans the entirety of the cell membrane to which it is permanently attached. Many transmembrane proteins function as gateways to permit the transport of specific substances across the membrane. They frequently undergo significant conformational changes to move a substance through the membrane.

Chimeric immunoreceptor useful in treating human cancers

InactiveUS20090257994A1Negligible toxicityPotent and selectiveBiocidePeptide/protein ingredientsIntracellular signallingMalignancy
The present invention relates to chimeric transmembrane immunoreceptors, named “zetakines,” comprised of an extracellular domain comprising a soluble receptor ligand linked to a support region capable of tethering the extracellular domain to a cell surface, a transmembrane region and an intracellular signalling domain. Zetakines, when expressed on the surface of T lymphocytes, direct T cell activity to those specific cells expressing a receptor for which the soluble receptor ligand is specific. Zetakine chimeric immunoreceptors represent a novel extension of antibody-based immunoreceptors for redirecting the antigen specificity of T cells, with application to treatment of a variety of cancers, particularly via the autocrin / paracrine cytokine systems utilized by human malignancy. In a preferred embodiment is a glioma-specific immunoreceptor comprising the extracellular targetting domain of the IL-13Rα2-specific IL-13 mutant IL-13(E13Y) linked to the Fc region of IgG, the transmembrane domain of human CD4, and the human CD3 zeta chain.

Cd20 antibodies and uses thereof

ActiveUS20110195022A1Improve stabilityImproved ADCC functionAntipyreticAnalgesicsDiseaseCD20
CD20 is a transmembrane protein of the tetra-spanin family expressed on the surface of B-cells and has been found on B-cells from peripheral blood as well as lymphoid tissues. CD20 expression persists from the early pre-B cell stage until the plasma cell differentiation stage. Conversely, it is not found on hematopoietic stem cells, pro-B cells, differentiated plasma cells or non-lymphoid tissues. In addition to expression in normal B-cells, CD20 is expressed in B-cell derived malignancies such as non-Hodgkin's lymphoma (NHL) and B-cell chronic lymphocytic leukemia (CLL). CD20 expressing cells are known to play a role in other diseases and disorders, including inflammation.

Colorectal cancer biomarker

The invention discloses a colorectal cancer biomarker, relating to application of interferon-induced transmembrane protein 1 in inhibition of endogenous retrovirus in colorectal cancer. The hESCs of IFITM1-KO is constructed by using CRISPR / Cas9 technology so as to study the functions of IFITM1. Studies find that the IFITM1-deleted human embryonic stem cell (hESCs) is identical with IFITM1-WT in the aspects of cell proliferation, cell pluripotency, telomere length, telomerase activity and the like. The expression of human endogenous retrovirus in hESCs of IFITM1-KO increases, and expression in para-carcinoma tissue is higher than that in colorectal carcinoma tissue. ChIP-qPCR detection finds that the enrichment of H3K9me3 in hESCs of IFITM1-KO is reduced at the HERVs site. Data shows that the expression level of IFITM1 in hESCs and colorectal carcinoma is in negative correlation to HERVs expression, and the IFITM1 can inhibit the expression of HERVs by regulating epigenetic inheritance.
