Effective immunity requires the coordinated activation of innate and adaptive immune responses. Natural killer (NK) cells are central innate immune effectors, but can also affect the generation of acquired immune responses to viruses and malignancies. How NK cells influence the efficacy of adaptive immunity, however, is poorly understood. Here, we show that(More)
BACKGROUND Neovascular, or wet, age-related macular degeneration causes central vision loss and represents a major health problem in elderly people, and is currently treated with frequent intraocular injections of anti-VEGF protein. Gene therapy might enable long-term anti-VEGF therapy from a single treatment. We tested the safety of rAAV.sFLT-1 in(More)
Airway inflammation is an important component of cystic fibrosis (CF) lung disease. We sought to determine whether alveolar macrophages were involved in early CF lung disease. Children with CF (median age 3.1 yrs) participated in a surveillance programme that included annual bronchoalveolar lavage (BAL). Control samples were obtained from non-CF children(More)
Major histocompatibility complex class I-restricted T-cell immunity is essential to control infection with cytomegalovirus (CMV), a clinically important virus that causes significant disease in immunocompromised individuals. Cross-presentation is considered the primary mode of antigen presentation to generate protective antiviral CD8⁺ T-cell immunity.(More)
PURPOSE To determine the efficacy of rAAV.sFlt-1-mediated gene therapy in a transgenic mouse model of retinal neovascularization (trVEGF029) and to assess whether rAAV.sFlt-1 administration generated any deleterious, long-lasting immune response that could affect efficacy. METHODS trVEGF029 mice were injected subretinally with rAAV.sFlt-1 or(More)
Since the plasticity and the potential for re-programming cells has become widely accepted, there has been great interest in cell-based therapies. These are being applied to a range of diseases, not least ocular diseases, where it is assumed that there is a reduced risk of immune rejection although this may be more perceived than real. There are two broad(More)
Many immune response genes are highly polymorphic, consistent with the selective pressure imposed by pathogens over evolutionary time, and the need to balance infection control with the risk of auto-immunity. Epidemiological and genomic studies have identified many genetic variants that confer susceptibility or resistance to pathogenic micro-organisms.(More)
PURPOSE Following a previous study that demonstrated a correlation between rhodopsin stability and the severity of retinitis pigmentosa (RP), we investigated whether predictions of severity can be improved with a regional analysis of this correlation. The association between changes to the stability of the protein and the relative amount of rhodopsin(More)
