摘要:
The invention relates to isolated nucleic acid molecules which code for antigens expressed by tumor cells which may be recognized by cytotoxic T cells, leading to lysis of the tumor cells which express it. This invention also relates to vectors which are designed to encode the antigen expressed by tumor cells and also to cells transfected by the nucleic acid molecules or vectors which comprise the nucleic acid molecules. Various therapeutic and diagnostic uses arising out of the properties of the nucleic acid molecules and the antigens for which these code are also part of this invention.
摘要:
The invention relates to the identification of a tumor rejection antigen precursor. It has been established that preprocalcitonin protein functions as a tumor rejection antigen precursor, and is processed to at least one tumor rejection antigen. Complexes of the tumor rejection antigen and an MHC molecule are recognized by cytolytic T lymphocytes, and lysed.
摘要:
The invention discloses immunogenic polypeptides comprising several MAGE-specific antigen epitopes selected from different (i.e. discrete) members of the MAGE protein family, nucleic acids coding therefor, recombinant viruses and/or cells comprising said nucleic acids, and compositions thereof. Methods for eliciting or inducing MAGE-specific immune responses utilizing the aforementioned immunogenic agents are also disclosed.
摘要:
The invention describes HLA class II binding peptides encoded by the EphA3 tumor associated gene, as well as nucleic acids encoding such peptides and antibodies relating thereto. The peptides stimulate the activity and proliferation of CD4+T lymphocytes. Methods and products also are provided for diagnosing and treating conditions characterized by expression of the EphA3 gene.
摘要:
The invention relates to peptides which bind to HLA-B35 molecules, leading to recognition and lysis of the resulting complexes by cytolytic T cells. Also a part of the invention are nucleic acid molecules which encode these peptides, and uses of each of these. The molecules are derived, in some cases, from tyrosinase, and portions of the tyrosinase molecule and portions of nucleic acid molecules which encode tyrosinase are also a part of the invention.
摘要:
Tumor rejection antigens presented by HLA-B44 molecules are described. These peptides are useful in diagnostic and therapeutic methodologies. The tumor rejection antigens are derived from MAGE tumor rejection antigen precursors.
摘要:
A method for determining cancers is described. The method involves assaying for expression of a gene coding for at least one of MAGE tumor rejection antigen or its precursor expression product.
摘要:
New tumor rejection antigen precursors, and the nucleic acid molecules which code for them, are disclosed. These tumor rejection antigen precursors are referred to as NAG tumor rejection antigen precursors, and the nucleic acid molecules which code for them are referred to as NAG coding molecules. Various diagnostic and therapeutic uses of the coding sequences and the tumor rejection antigen precursor molecules are discribed.
