Stem cell transplantation is already in clinical practice for certain genetic diseases and is a promising therapy for dystrophic muscle. We used the mdx mouse model of Duchenne muscular dystrophy to investigate the effect of the host satellite cell niche on the contribution of donor muscle stem cells (satellite cells) to muscle regeneration. We found that incapacitation of the host satellite ce...
BACKGROUND Electrophysiological mismatch between host cardiomyocytes and donor cells can directly affect the electrical safety of cardiac cell therapies; however, the ability to study host-donor interactions at the microscopic scale in situ is severely limited. We systematically explored how action potential (AP) differences between cardiomyocytes and other excitable cells modulate vulnerabilit...
Heterosexual transmission of HIV-1 is characterized by a genetic bottleneck that selects a single viral variant, the transmitted/founder (TF), during most transmission events. To assess viral characteristics influencing HIV-1 transmission, we sequenced 167 near full-length viral genomes and generated 40 infectious molecular clones (IMC) including TF variants and multiple non-transmitted (NT) HI...
Acute graft-versus-host disease (GVHD) results from the attack of host tissues by donor allogeneic T cells and is the most serious limitation of allogeneic hematopoietic cell transplantation (allo-HCT). Host antigen-presenting cells are thought to control the priming of alloreactive T cells and the induction of acute GVHD after allo-HCT. However, whereas the role of host DC in GVHD has been est...
The survival of donor corneal epithelium was investigated in rabbits after they received unilateral 8 mm diameter lamellar keratoplasties with living donor tissue of a different sex from the host. Three weeks, 6 weeks, and 12 weeks postoperatively, cultured corneal epithelia, grown from 5 mm diameter central buttons, the adjacent 0.75 mm wide donor rings, the peripheral 10 to 13 mm diameter rin...
To evaluate the potential for nonviremic transmission (NVT) of West Nile virus (WNV) to occur in nature, we examined the effect of increasing spatial and temporal separation between co-feeding mosquitoes on the efficiency of nonviremic transmission and the potential of a West Nile virus bridge vector species, Aedes albopictus, to be infected via nonviremic transmission. West Nile virus-infected...
One of the principal challenges in epidemiological modeling is to parameterize models with realistic estimates for transmission rates in order to analyze strategies for control and to predict disease outcomes. Using a combination of replicated experiments, Bayesian statistical inference, and stochastic modeling, we introduce and illustrate a strategy to estimate transmission parameters for the ...
