Newly found sensing system enables certain bacteria to resist human immune defenses

... how gram-positive bacteria—such as those that can lead to food poisoning, skin disorders and toxic shock—avoid being killed by AMPs. AMPs are made by virtually all groups of organisms, including amphibians, insects, several invertebrates and mammals, including humans. “Gram-positive bacteria are major...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

...esults, as finding the genes doesn't automatically lead to a cure," says Mr Noble. "Nevertheless, this new result tells us something very important about what the eye is doing normally and about a new and common way in which it can go wrong. Given some exciting recent developments on testing possible cure...

Researchers reveal structure of protein altered in autism

...ptic development in nerve connections is likely to lead to cognitive deficits seen in patients with autism,” said Taylor. He added that synapse formation and maintenance occurs early in development when the infant brain is still plastic and formative. Therefore, by understanding the structural mutations...

Could fungal collection hold the key to new life-saving drugs?

...activity in samples of natural products that could lead to new medicinal products. Previous work at SIDR found activities from plant extracts against diabetes, obesity and psoriasis. Professor Alan Harvey, Director of SIDR said: “We are delighted to be working with CABI and to have access to their f...

Herpes virus hijacks DNA repair process

... and is very important to preventing cancer," says lead author Vera Tarakanova, Ph.D., a postdoctoral fellow. "However, by targeting the viral protein responsible for activating the DNA damage response, we may be able to block viral replication. In addition, determining how the DNA repair response helps v...
