BACKGROUND: Cardiac gene therapy using the adeno-associated virus serotype 9 vector is widely used due to its efficient transduction. However, the promoters used to drive expression often cause off-target localization. To overcome this, former studies have applied cardiac specific promoters but the expression is debilitated compared to that of ubiquitous promoters. To address these issues in the context of atrial specific gene expression, an enhancer calsequestrin cis-regulatory module 4 (CRM4) and the highly atrial specific promoter sarcolipin were combined to enhance expression and minimize off tissue expression...

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, the fragility of these cells during ex vivo manipulation, and clinically meaningful engraftment following transplantation. With these challenges in mind, we were interested in determining (i) whether gene-corrected cells at progressively lower numbers can successfully engraft in FA; (ii) whether low-dose conditioning facilitates this engraftment; and (iii) whether these cells can 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: 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)...
