In order to strengthen the efficacy of vaccines on the immune system, and in particular on T lymphocytes, specialized in the detection of cancer cells, researchers have developed spider silk microcapsules capable of delivering the vaccine directly to the heart of immune cells.
An international team of researchers engineered a cell-like structure that harnesses photosynthesis to perform metabolic reactions, including energy harvesting, carbon fixation and cytoskeleton formation.
Scientists have constructed an enzyme than can penetrate a mammalian cell and accelerate the release of a hormone. This then activates a gene switch that triggers the creation of a fluorescent protein.
Scientists are reporting an innovative new method to screen for potential cancer drugs. The technique makes use of tiny, three-dimensional ball-like aggregates of cells called spheroids. These structures can be used to interrogate hundreds or even thousands of compounds rapidly using a technique called high throughput screening.
