Self-assembling nanoparticles an effective vaccine candidate for SARS-CoV-2

The currently developed vaccines against SARS-CoV-2 include the RBD in their immunogen. With a similar objective, a new study developed an RBD protein-based vaccine candidate against the SARS-CoV-2, using self-assembling Helicobacter pylori-bullfrog ferritin nanoparticles as an antigen delivery system. The study is published recently in the journal mBio (by the American Society of Microbiology).

Modulation of oral microbiota impacts the cardiovascular benefits of sport

Exercise plays a key role in maintaining good physical and mental health throughout life. There is an increasing amount of scientific evidence that some of the immune system and metabolism benefits provided by sport are related to the thousands of millions of bacteria that colonize the digestive tract, from the mouth to the intestines, known as microbiota.
