Scripps research scientists engineer new type of vaccination that provides instant immunity

... area. In addition, the most common vaccination strategies use whole proteins, viruses, or other complex immunogens not just the specific part of the macromolecule that is recognized by the immune system to elicit an immune response, which makes for wasted immune activity. Then there is the body's own kinetics ...

New understanding of how big molecules bind will lead to better drugs, synthetic organic materials

...em depend on geometrical features. It is the geometrical arrangement of the component parts, as much as their chemical identity, that determines how a macromolecule will behave and interact with other molecules both large and small. Some molecules will only react or bind with certain others, often temporarily, on ...

An All Important Breakthrough Reached In Understanding T cell response For Parasitic Diseases

...overed is that the T cell response in T. cruzi is highly focused on a relatively small set of cellular features called 'epitopes,' which are part of a macromolecule that is recognized by the immune system. The specific epitopes involved are ones encoded by the trans-sialidase (or 'ts') family of genes. 'The ...
