High-precision human immune aging clock identifies RUNX1 as key target for T cell senescence
The immune system acts as a critical sentinel of organismal aging, integrating the sensing of physiological states with the execution of defense and clearance functions. Immunosenescence not only reflects systemic functional ...

Programming the immune system to manufacture its own therapeutic proteins
An innovative gene-editing strategy could establish a new way for the body to manufacture therapeutic proteins—including certain kinds of highly potent antibodies that are naturally difficult to produce—by reprogramming the ...

A hidden army of zombie immune cells may drive fatty liver disease, inflammation and aging
UCLA researchers have identified a rogue population of immune cells that quietly accumulates in aging tissues and in the livers of people with fatty liver disease. Clearing these cells, they found, dramatically reduced inflammation ...

Immune system uses a conveyor belt-like process to edit defective antibodies, new research finds
The immune system's B cells create antibodies that can mount a response against just about anything—either destroying a pathogen or instructing the rest of the immune system to go after the offender. But what happens when ...

How a misdirected DNA alarm could reshape treatment for rare rapid-aging diseases
The human immune system is finely tuned to detect and destroy viral threats. But this same defense system can misfire. When fragments of the body's own damaged DNA are mistaken for viral invaders, the result is a powerful, ...

Silent B-cell mutations may build for years before thyroid autoimmunity appears
New research suggests that autoimmune diseases may be driven by DNA mutations in immune cells that remove the natural brakes on the immune system. It reveals a previously hidden role for somatic mutations—DNA changes acquired ...

Taking a closer look at immune 'memory' could spur progress in the fight against lethal illnesses
The average human has about 1.8 trillion immune cells. These cells patrol the body for bacteria, viruses, cancers, and other threats. Vaccines enhance this security system by teaching our immune cells to target specific pathogens. ...

High antibodies create disparities in donor search for blood and bone marrow transplants
People who have elevated levels of donor-specific anti-HLA antibodies (DSAs)—immune system proteins that can target and attack donor stem cells—wait an average of three additional months to receive blood or bone marrow transplants ...

Neuroinflammation triggers autism-like regression in mouse model
Autism spectrum disorder (ASD) is a neurodevelopmental condition estimated to affect approximately 1 in 100 children worldwide. This condition is characterized by differences in how people communicate and interact with others, ...
Why some vaccine side effects may be avoidable without weakening protection
Vaccines play a critical role in preventing infectious diseases, but their success often depends on adjuvants—substances that enhance immune responses. While these compounds improve vaccine effectiveness, they can also trigger ...
