Hepatitis C virus found to spread directly from cell to cell by-passing antibodies

Scientists looking for an effective treatment for Hepatitis C may face an even bigger task than anticipated. Recent studies looking into how the virus spreads in liver tumour cells have demonstrated that the virus uses two different routes, which may explain why the body's natural occurring antibodies are ineffective at controlling the virus.

Does neural cell adhesion molecule-180 predict survival in colorectal cancer?

When a person learns they are suffering from cancer, the first question in their mind is always: "How much time do I have?" Unfortunately, this is a question to which the researchers have long been seeking an absolute answer.

Hairpin peptide mimetics show promise as new drugs to fight HIV

When a host cell is infected with HIV, the virus brings its own genetic material into the host cell. This cell then replicates, reads the viral RNA, and uses it as a blueprint to produce more viral proteins.

New designer toxins kill Bt-resistant insect pests

A new way to combat resistant pests stems from discovering how the widely used natural insecticide Bt kills insects.

Immune cell age plays role in retinal damage in age-related macular degeneration

Studying a mouse model of age-related macular degeneration, the leading cause of blindness in older Americans, scientists at Washington University School of Medicine in St. Louis have found age is key in determining whether damaging blood vessels will form beneath the retina and contribute to vision loss.

Gamma interferon could aid fight against fungal infections

Interferon, the "superhero" cure for viral infections, may be a strong weapon in the battle against fungal infections in immunocompromised patients, according to an article in the November issue of Microbiology Today.
