An immune molecule that appeared in evolution long before blood circulation may help improve cancer immunotherapy. Scientists at Nagoya University in Japan discovered that complement C3 can prevent immune-suppressing cells from building up inside tumors, but only when the protein is produced locally within the tumor. C3 traveling through the bloodstream did not influence how well treatment worked.

Long space missions can force small crews to endure isolation, cramped living conditions, and intense psychological pressure for months at a time. To better understand how those conditions shape teamwork, an international research group studied a ten-month overwintering mission at Concordia Station in Antarctica.

A study funded by the National Institutes of Health (NIH) has uncovered a major shift in the immune environment of the hippocampus, the part of the brain that plays a central role in learning and memory. The findings suggest that this immune remodeling begins in midlife and may help explain how aging contributes to the long lasting brain inflammation often seen in neurodegenerative diseases.

A UCLA Health study in mice has found that inflammation during pregnancy can produce lasting autism-like changes in offspring. The researchers also discovered that many of the resulting brain and behavioral effects could be improved rapidly in adulthood, although only temporarily, with a single dose of the immune-suppressing drug rapamycin.

Popular weight-loss and diabetes medications such as semaglutide and Ozempic belong to a broader group known as GLP-1 drugs. A study funded by the National Institutes of Health (NIH) has now identified a previously unrecognized way that some newer oral drugs in this class may affect the brain.

Colorectal cancer has become the leading cause of cancer related death among people younger than 50. Although routine screening generally begins at age 45 for adults at average risk, warning signs can appear earlier and should be discussed with a health care provider at any age.

New research has revealed that tau, a protein best known for its connection to Alzheimer's disease, is also essential for creating long lasting memories. The discovery provides new insight into how healthy memory works and could help guide future efforts to develop treatments for dementia.

An experimental drug developed at Michigan Medicine has shown the ability to reverse severe fatty liver disease in animal studies by restoring gut health. The findings, published in The Journal of Clinical Investigation, suggest that targeting the connection between the gut and liver could offer a promising new approach for treating metabolic dysfunction-associated steatohepatitis (MASH).
