摘要:
Featured are cells and methods of use thereof for modulating an antigen-specific immune response in a subject. The cells comprise a set of transgenes comprising two or more of PD-L1, HLA-G or H2-M3, Cd47, Cd200, FASG or FasL, Ccl21 or Ccl21b, MfgeS and Serpin B9 or Spi6, that shield the cells from immune surveillance (ie. "cloaking genes"). The cells can be used to induce immune tolerance to an antigen (e.g., a donor alloantigen or a self-antigen), or to induce an immune response to (e.g., induce the production of antibodies directed against) a non-self antigen.
摘要:
本发明提供一种具有弓形虫免疫原性的蛋白,该蛋白为cyclophilin突变体蛋白,由SEQ ID 2所述氨基酸序列组成。本发明还提供一种可编码具有弓形虫免疫原性的蛋白的核酸,具有SEQ ID 1所述的核酸序列。本发明提供一种疫苗,是将弓形虫抗原基因双酶切后连接pET28a等原核表达载体,转化入BL21(DE3)等原核表达工程菌,诱导其高效表达,纯化后得到的蛋白为可溶性蛋白,并且保持其特有的免疫原性。

摘要:
The present invention relates to methods of screening biological samples for the presence of T. gondii. More particularly, the present invention relates to a sensitive and specific screening test for the presence of Toxoplasmosis in subjects by using or detecting the in vivo-induced T. gondii RAP domain binding protein antigen. The invention further relates to the use of the in vivo-induced antigen in the prevention or therapy of Toxoplasmosis.
摘要:
A presente invenção descreve uma sequência nucleotídica resultante da modificação e redução do gene que codifica a proteína A2 de Leishmania, bem como seu processo de obtenção e seus usos e uma composição vacinal contendo a proteína obtida a partir deste gene modificado. As modificações introduzidas viabilizam a execução mais eficiente de técnicas de Biologia Molecular, como PCR, clonagem e expressão heteróloga, bem como permitem a expressão da proteína A2HIS-OZ em células procarióticas com maior rendimento. Esses aspectos são especialmente interessantes para o controle de qualidade e produção da proteína em escala industrial. A proteína A2HIS-OZ obtida a partir deste gene modificado poderá ser utilizada como antígeno vacinal na prevenção de leishmaniose canina ou humana ou como antígeno para imunodiagnóstico da leishmaniose visceral.
摘要:
Genetically modified (transgenic) true grasses that are resistant to infection by rust fungi are provided, as are methods of making such transgenic plants. The true grasses are genetically modified by gene silencing of fungal patliogenicity genes that are normally expressed in haustoria.

A synthetic nucleotide, which transcribes as the cell-traversal protein for ookinetes and sporozoites (CelTOS) antigen of Malaria Plasmodium , and methods of use thereof.
摘要:
This invention relates to a novel recombinant chimera of DNA construct having esat-6 region of Mycobacterium tuberculosis and kinesin region of Leishmania donovani cloned together on two sides of self cleaving peptide in a DNA vaccine vector pVAX-1 wherein the Chimeric construct is operatively linked to a transcriptional promoter thus capable of self replication and expression within the mammalian cell and the process of preparation thereof comprising. Analysis of the predicted protein sequence of kinesin motor domain and esat-6 domain using Promiscuous MHC Class-1 Binding Peptide Prediction Servers. Amplification of gene coding for kinesin motor domain and esat-6 domain. Cloning of kinesin esat-6 gene region in pGEM-T® vector for sequence analysis. Generation of Chimeric construct by directional cloning in pVAX-1 vector. In-vitro expression analysis of kenesin motor domain and esat-6 domain from the clones using cell free translation system and immunogenicity studies, Splenocyte proliferative and cytokines studies using the above mentioned constructs.
摘要:
The present invention relates to recombinant anÍ-Theileria parva vaccines and the administration of such vaccines to animals, advantageously bovines. Advantageously, the anti-Theileria parva vaccine encompasses a recombinant avipox virus that includes a nucleotide sequence encoding a TheÊleria parva gene. The invention further relates to methods of vaccinating animals, advantageously bovines, by administration of anÍ-Theileria parva vaccines that may encompass a recombinant avipox virus that may contain a Theileria parva gene.
