Cow antibodies bring hope for effective AIDS vaccine soon

Cow antibodies bring hope for effective AIDS vaccine soon

In a significant find, a team of researchers has reported for the first time elicitation of powerful, HIV-blocking antibodies in cows in a matter of weeks — a process that usually takes years in humans — paving the way for developing a broadly effective AIDS vaccine in the near future. According to the study, published in the prestigious journal Nature, the unexpected discovery in cows is providing clues for important questions at a moment when new energy has infused HIV vaccine research. “One approach to a preventive HIV vaccine involves…

Genetically-engineered mosquitoes give hope against dengue

Genetically-engineered mosquitoes give hope against dengue

In a first, researchers have genetically engineered mosquitoes that have an increased resistance to infection by the dengue virus. After decades of research and countless control attempts, dengue continues to infect an estimated 390 million people around the world each year. Now, researchers report that mosquitoes carrying dengue virus (DENV) can be genetically engineered, giving an increased resistance to infection by the virus. When a mosquito bites someone infected with DENV, the virus needs to complete its lifecycle in the mosquito’s gut, eventually infecting its salivary glands, before it can…

New hope for patients with deadly brain tumour

New hope for patients with deadly brain tumour

Non-invasive gene therapy could treat brain tumour (Fatine El Hassani/Getty Images) Researchers have found a potential new way of stopping one of the most aggressive types of brain tumour from spreading, which could also lead the way to better patient survival. Glioblastoma, which is one of the most common types of malignant brain tumours in adults, grow fast as well as spread easily. The tumour has threadlike tendrils that extend into other parts of the brain making it difficult to remove it all, the study from the University of Southampton…
