BOSTON - During the development and progression of Alzheimer s disease, a protein called tau accumulates and spreads in the brain. Understanding the mechanisms behind tau spread and its consequences may point to new prevention and treatment strategies for Alzheimer s disease and other forms of dementia. New insights now come from research that was led by investigators at Massachusetts General Hospital (MGH) and involves an anesthetic known to affect cognitive function. The findings are published in
The scientists note that inflammation plays an important role in Alzheimer s disease, and microglia immune cells that reside in the brain are thought to be involved in this process by producing an inflammatory molecule called interleukin-6. To see if tau stimulates microglia to drive the development of Alzheimer s disease pathology, the MGH investigators and their colleagues conducted experiments with an inhaled anesthetic called sevoflurane. Their previous work showed that sev

The U.S. agency granting use of the shot in adolescents will also accelerate the nation s efforts to drive down infections, public health officials and infectious disease experts say.
The two-dose vaccine is already authorized for use in people 16 and older. The Centers for Disease Control and Prevention s vaccine advisory committee has scheduled a meeting Wednesday to review the shots for kids. If approved by the CDC as expected, it could be distributed to adolescents as soon as this week.
Acting FDA Commissioner Dr. Janet Woodcock said the decision brings us closer to returning to a sense of normalcy and to ending the pandemic. She assured parents that the agency undertook a rigorous and thorough review of all available data before clearing it for use in the teens.
