BACKGROUND: Gene therapy approaches for the treatment of Fanconi anemia (FA) hold promise for patients without a suitably matched donor for an allogeneic bone marrow transplant. However, significant limitations include the collection of sufficient stem cell numbers from patients, fragility of these cells during ex vivo manipulation, and clinically meaningful engraftment following transplantation. With these challenges in mind, we were interested in determining if gene-corrected cells at progressively lower numbers can successfully engraft in FA, if low-dose conditioning facilitates this engraftment, and if these cells can artificially be selected for post-transplant...

BACKGROUND: Vertical HIV transmission does not occur in all exposed infants. Many infants remain HIV uninfected even after exposure. This is partly attributed to the host genes involving cytokine production, which is rarely documented in vertical transmission. METHODS: Here, an observational cohort study evaluated whether polymorphisms in cytokine, receptor and antagonist genes are associated with perinatal HIV transmission. Single nucleotide polymorphism (SNP) genotyping was performed via the polymerase chain reaction with sequence-specific primers method...

BACKGROUND: Following systemic delivery, AAV9-mediated gene expression is significantly increased in ischemic versus non-ischemic muscle, suggesting that AAV9 is an attractive vector for treating peripheral arterial disease. Potential mechanisms underlying ischemia-augmented expression include: (i) increased vascular permeability and (ii) "unmasking" of endogenous AAV9 receptors. In the present study, we aimed to reconstitute the ischemic induction of AAV9 in vivo, using local injection of histamine (to increase vascular permeability) and neuraminidase (to desialylate cell surface glycans)...

BACKGROUND: The trisynaptic circuit (entorhinal cortex-dentate gyrus-CA3-CA1) is a key unidirectional network in the hippocampus. Damage to the hippocampus interrupts this circuit and causes neurological disorders. Efficient delivery of therapeutic genes into this network is of great interest with respect to treating trisynaptic circuit pathologies. METHODS: We generated a lentivector system pseudotyped by a variant of rabies glycoprotein, FUG-B2. The efficiency of the vector in the retrograde transduction of the rat hippocampal neurons (i...

BACKGROUND: Bone morphogenetic protein (BMP)-2 gene-activated muscle tissue fragments can regenerate large bone defects in preclinical animal models. The use of tissue fragments instead of isolated cells expedites gene-enhanced tissue engineering and may increase the possibility of clinical translation. The present in vitro study investigated whether the osteoinductive effect of BMP-2 on muscle tissue fragments can be enhanced using the heterodimers BMP-2/6 or BMP-2/7. METHODS: Skeletal muscle tissue fragments from rats were cultured in vitro for up to 20 days in normal medium, osteogenic medium or osteogenic medium supplemented with either a low (50 ng/ml) or high (200 ng/ml) concentration of recombinant human BMP-2, BMP-2/6 or BMP-2/7...

BACKGROUND: Previous studies have shown that foamy viral (FV) vectors are a promising alternative to gammaretroviral and lentiviral vectors and also that insulators can improve FV vector safety. However, in a previous analysis of insulator effects on FV vector safety, strong viral promoters were used to elicit genotoxic events. In the present study, we developed and analyzed the efficacy and safety of a high-titer, clinically relevant FV vector driven by the housekeeping promoter elongation factor-1α and insulated with an enhancer blocking A1 insulator (FV-EGW-A1)...

INTRODUCTION: Intrathecal interleukin (IL)-10 delivered by plasmid or viral gene vectors has been proposed for clinical testing because it is effective for chronic pain in rodents, is a potential therapeutic for various human diseases, and was found to be nontoxic in dogs, when the human IL-10 ortholog was tested. However, recent studies in swine testing porcine IL-10 demonstrated fatal neurotoxicity. The present study aimed to deliver vector-encoded human IL-10 in swine, measure expression of the transgene in cerebrospinal fluid and monitor animals for signs of neurotoxicity...

BACKGROUND: Autoimmune hepatitis (AIH) is an inflammatory disease caused by an aberrant immune response to hepatic self-antigens in which regulatory T cells (Tregs) are critical for maintaining immunosupression. The soluble form of fibrinogen-like protein 2 (sFGL2), a novel effector molecule of Treg, is rarely investigated in AIH. In the present study, we dissected the role of sFGL2 in autoimmune hepatitis and its potential mechanism underlying AIH progression. METHODS: Plasma and intrahepatic sFGL2 levels, as well as Treg cells, were measured in both AIH patients and experimental autoimmune hepatitis (EAH) mice...

BACKGROUND: Levels of circulating vascular endothelial growth factor (VEGF) (a potent endothelial-cell-specific angiogenic factor) have been correlated with disease activity in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). In addition, several single nucleotide polymorphisms (SNPs), including the VEGFA -2578C/A, have been associated with RA in some populations. By contrast, the role of different VEGFA SNPs in the susceptibility to SLE has received little attention...
