Here’s what morning sickness during pregnancy really means
UCLA researchers have uncovered a link between “morning sickness” symptoms and the body’s natural, but complex, inflammatory response to biological and bodily changes during pregnancy.

Seven-year study reveals rheumatoid arthritis begins long before symptoms, opening door to prevention
Scientists have discovered that rheumatoid arthritis (RA) doesn’t start when the pain begins. It silently starts years earlier. RA is a debilitating autoimmune disease that causes painful joint inflammation and damage. The new research reveals that peo…
Enhanced CAR T cells emerge from genetic screening
CAR T cells are patient-derived, genetically engineered immune cells. They are “living drugs” and constitute a milestone in modern medicine. Equipping T cells, a key cell type of the immune system, with a “chimeric antigen receptor” (CAR) enables them …
‘Primed and ready’: How one fast-acting type of white blood cell fights off infection in infants
From the moment they’re born, newborns—or, specifically, their immune systems—must learn to fight germs without harming their own tissues.
These cells have hidden powers that could heal brain injuries
Healing from any injury involves a delicate balance between scarring and inflammation—two processes that can wreak havoc as well as make repairs.
Unlocking the immune system’s instruction manual: How T follicular helper cells mount a flexible response
Scientists have uncovered how a key type of immune cell adapts its behavior depending on the type of infection, paving the way for better vaccines and advancing research into immune-related diseases.
‘Rogue’ scaffolding cells may hold key to treating multiple diseases at once
Scientists have mapped underappreciated scaffolding cells in skin, known as fibroblasts. They show for the first time how fibroblasts go ‘rogue’ in many different diseases affecting multiple organs—from acne and psoriasis, to rheumatoid arthritis and i…
How cell skeleton defects can teach immunology
For immune cells, the actin cytoskeleton is more than a structural scaffold. Immune cells can migrate to sites of infection or form precise, short-lived contacts with other cells, by constantly reshaping their actin cytoskeleton. Genetic errors in the …
Engineered gut bacteria improve survival outcomes in colorectal cancer tumors
In a new study that combines synthetic biology with cancer immunotherapy, researchers from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) and Central South University in China have developed an engineered strain of…
Tuberculosis bacterium disables key immune sensor to evade host defenses, study reveals
A research team has uncovered a new mechanism that allows Mycobacterium tuberculosis (Mtb), the bacterium that causes tuberculosis (TB), to evade host immune defenses.
