PURPOSE TNFerade is a second-generation replication-deficient adenovector carrying a transgene encoding human tumor necrosis factor alpha under control of a radiation- induced promoter. The objective of this study was to assess the tolerance of combining TNFerade and radiation therapy in patients with soft tissue sarcomas of the extremity. EXPERIMENTAL DESIGN TNFerade was administered in comb...
BACKGROUND AND AIMS Preparative hepatic irradiation (HIR), together with mitotic stimulation of hepatocytes, permits extensive hepatic repopulation by transplanted hepatocytes in rats and mice. However, whole liver HIR is associated with radiation-induced liver disease (RILD), which limits its potential therapeutic application. In clinical experience, restricting HIR to a fraction of the liver ...
BACKGROUND A protective malaria vaccine will likely need to elicit both cell-mediated and antibody responses. As adenovirus vaccine vectors induce both these responses in humans, a Phase 1/2a clinical trial was conducted to evaluate the efficacy of an adenovirus serotype 5-vectored malaria vaccine against sporozoite challenge. METHODOLOGY/PRINCIPAL FINDINGS NMRC-MV-Ad-PfC is an adenovirus vec...
BACKGROUND Individuals without prior immunity to a vaccine vector may be more sensitive to reactions following injection, but may also show optimal immune responses to vaccine antigens. To assess safety and maximal tolerated dose of an adenoviral vaccine vector in volunteers without prior immunity, we evaluated a recombinant replication-defective adenovirus type 5 (rAd5) vaccine expressing HIV-...
An adenoviral vector with RGD-modified fibers and expressing the human tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) gene from the human telomerase reverse transcriptase (hTERT) promoter (designated Ad/TRAIL-F/RGD) was constructed, and its antitumor activity was evaluated in vitro and in vivo. An in vitro study showed that treatment with Ad/TRAIL-F/RGD elicited a high rate of ...
Background: Numerous evidences indicate that in some HIV-1 positive patients, the humoral and cellular immune responses are induced against HIV-1 proteins and this is inversely related to the progress of infection. Objective: The aim of this study was the evaluation of the Adenovectors containing HIV genes in induction of immune responses in mice. Methods: The HIV-1 genes including gag p24, rev...
BACKGROUND Although CD4 T cells are crucial for defense against M.tb, it is still not clear whether the optimal response against M.tb in fact involves both CD4 and CD8 T cells. To test this, we used a new vaccine strategy that generated a strong balanced T cell response consisting of both CD4 and CD8 T cells. METHODS AND FINDINGS To compare CD4 and CD8 responses against Ag85B-TB10.4 (H4), H4 ...
Alveolar type II cell proliferation occurs after lung injury and is thought to minimize the subsequent fibrotic response. Keratinocyte growth factor (KGF) has been shown to be a potent growth factor for rat alveolar type II cells. In this study, we created a replication-deficient, recombinant human type 5 adenovirus vector expressing human KGF (Ad5-KGF) to produce alveolar type II cell hyperpla...
Replication-deficient adenoviral vectors (AdVec), which infect cycling and noncycling cells with high efficiency, low toxicity, and ease of delivery, provide ideal vehicles to study the expression of regulatory genes controlling different stages of hematopoiesis. To examine the infection efficiency of AdVec in hematopoietic precursor and progenitor cells, we used a replication-deficient adenove...
