The present invention provides a method for effectively and reproducibly infecting canines with Leishmania infantum using sand flies to vector the parasite. The inventive method comprises several steps, including ensuring canines are naïve to Leishmania, infecting the canines using bites of Leishmania-infected sand fly bites, and evaluating successful transmission of the Leishmania parasites.

The invention provides recombinant adenoviral vectors which are capable of eliciting immunity against the pre-erythrocytic stage of the life cycle of the malaria parasite. In particular, the invention provides a recombinant, replication deficient simian adenoviral vector which encodes an antigen comprising the thrombospondin-related adhesion protein (TRAP), and also immunogenic compositions (e.g. vaccines) comprising the vector and methods of using such compositions.
摘要:
A mouse with a humanization of the mIL-3 gene and the mGM-CSF gene, a knockout of a mRAG gene, and a knockout of a mII2rg subunit gene; and optionally a humanization of the TPO gene is described. A RAG/II2rg KO/hTPO knock-in mouse is described. A mouse engrafted with human hematopoietic stem cells (HSCs) that maintains a human immune cell (HIC) population derived from the HSCs and that is infectable by a human pathogen, e.g., S. typhi or M. tuberculosis is described. A mouse that models a human pathogen infection that is poorly modeled in mice is described, e.g., a mouse that models a human mycobacterial infection, wherein the mouse develops one or more granulomas comprising human immune cells. A mouse that comprises a human hematopoietic malignancy that originates from an early human hematopoietic cells is described, e.g., a myeloid leukemia or a yeloproliferative neoplasia.
摘要:
This invention refers to a mouse for human hepatitis studies wherein the mouse has been injected with CD34+ stem cells and wherein the mouse is immunocompromised, as well as a method of manufacturing a mouse model comprising administering CD34+ stem cells as defined herein into an immunocompromised mouse as defined herein. The invention also refers to the use of a mouse as defined for testing the efficiency of putative anti-HBV or anti-HCV drugs or for characterizing changes in viral quasispecies during HBV or HCV infection.
摘要:
The present invention provides an expression vector for preventing or inhibiting HlV entry, fusion or replication in mammalian cells. In particular, the invention provides a recombinant retroviral vector that encodes an inhibitor of a HlV co-receptor, such as CCR5 or CXCR4, and a protein that inhibits HIV fusion to target cells and/or HIV replication. Pharmaceutical compositions comprising such constructs and methods of use thereof to prevent or treat HIV infection in a patient are also disclosed.

The present invention provides a mouse with liver damage, having a high degree of damage against the mouse's original hepatocytes while having a uPA gene in a heterozygous form, and a method for efficiently preparing the mouse. Specifically, the method for preparing a mouse with liver damage having the uPA gene in a heterozygous form comprises the following steps of: (i) transforming mouse ES cells with a DNA fragment containing a liver-specific promoter/enhancer and cDNA that encodes a urokinase-type plasminogen activator operably linked under the control thereof; (ii) injecting the transformed mouse ES cells obtained in step (i) into a host embryo; (iii) transplanting the host embryo obtained in step (ii) via the injection of the ES cells into the uterus of a surrogate mother mouse, so as to obtain a chimeric mouse; and (iv) crossing the chimeric mice obtained in step (iii), so as to obtain a transgenic mouse in which the DNA fragment is introduced in a heterozygous form.
