Anthrax paralyzes immune cells with lethal toxin, UF research shows

... form of anthrax paralyzes the body's defenses and prevents immune cells from reaching the site of infection. ...n a previous study, Southwick found that the toxin prevents actin assembly, leaving neutrophils stuck in the mud. "Actin is important because it's the motor ...

First clinical trial of gene therapy for childhood blindness

...ity in a particular gene called RPE65. This defect prevents normal function of the retina, the light-sensitive layer of cells at the back of the eye. This results in severely impaired vision from a very young age and there are currently no effective treatments available. The new technique that will be use...

Understanding why C. difficile causes disease -- it's hungry

...es and the other codes for a protein called C that prevents R from acting. A mutation in the C protein gene, leaving R unchecked, is the cause of the hypervirulent strain. Sonenshein and his colleagues are currently working to identify a protein that might shut down the gene that codes for R. By identif...

Blood-brain barrier breached by new therapeutic strategy

...ses of the brain is the blood-brain barrier, which prevents systemically delivered therapeutic drugs from reaching the brain. Grantees of the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, have now shown that a short protein (peptide) from the rabies virus ca...

Now, self-healing materials can mimic human skin, healing again and again

...etwork, ‘scar tissue’ builds up in the coating and prevents the healing agent from reaching the catalyst.” In the current system, the healing process stops after seven healing cycles. This limitation might be overcome by implementing a new microvascular design based on dual networks, the researchers suggest...
