The method by which a baby was delivered is associated with how its immune system will respond to two key childhood vaccines, research suggests. Babies born naturally were found to have higher antibody levels, compared with those born via Caesarian section after receiving their jabs that protect against bacteria that cause lung infections and meningitis. Experts say the findings could help to inform conversations about C-sections between expectant mothers and their doctors, and shape the design of more tailored vaccination programs.

Leprosy is one of the world's oldest and most persistent diseases but the bacteria that cause it may also have the surprising ability to grow and regenerate a vital organ. Scientists have discovered that parasites associated with leprosy can reprogram cells to increase the size of a liver in adult animals without causing damage, scarring or tumors. The findings suggest the possibility of adapting this natural process to renew aging livers and increase healthspan -- the length of time living disease-free -- in humans.

Scientists have developed a novel concept of a nose-to-brain system for the clinical application of neuropeptides. They developed a derivative of glucagon-like peptide-2 and found that when administered intranasally, it is efficiently delivered through the trigeminal nerve to the site of action and exhibits antidepressant-like effects. This is the first demonstration in the world that intranasally administered neuropeptides reach the brain (hippocampus and hypothalamus) via neurons.
