Journal ArticleDOI

Prevalent Class I-Restricted T-Cell Response to the Theiler’s Virus Epitope Db:VP2121–130 in the Absence of Endogenous CD4 Help, Tumor Necrosis Factor Alpha, Gamma Interferon, Perforin, or Costimulation through CD28

TL;DR: Results demonstrate that VP2121–130 presented in the context of Db is an immunodominant epitope in TMEV infection and that the frequency of the VP2 121–130-specific CTLs appears to be independent of several key inflammatory mediators and genetic background but is regulated in part by the expression of CD4.
Journal ArticleDOI

Systemic Delivery of Human Growth Hormone or Human Factor IX in Dogs by Reintroduced Genetically Modified Autologous Bone Marrow Stromal Cells

TL;DR: The results demonstrate that the ex vivo bone marrow stromal cell system is a potentially powerful method by which to deliver secreted transgene product to the systemic circulation of large animals.
Journal ArticleDOI

Donor-specific hypo-responsiveness occurs in simultaneous liver-kidney transplant recipients after the first year

TL;DR: The phenotypic and functional characteristics of the circulating blood cells of the simultaneous liver-kidney transplant recipients resembled those of solitary liver transplant recipients, and appear to be associated with donor-specific hypo-alloresponsiveness.
Journal ArticleDOI

Retroviral vector-modified bone marrow stromal cells secrete biologically active factor IX in vitro and transiently deliver therapeutic levels of human factor IX to the plasma of dogs after reinfusion.

TL;DR: It is demonstrated that retroviral vector-modified BMSCs can deliver human therapeutic levels of hFIX to the circulation of dogs and that dog anti-hFIX antibodies may have masked potentially longer duration expression in vivo.
