Japanese Researchers Discover Immune Hubs Linked to Arthritis
Imagine your body has a disease called rheumatoid arthritis that makes your joints hurt.
Scientists in Japan have discovered tiny immune 'hubs' inside the joints where this disease causes problems.
Inside these hubs are special cells that make the disease worse.
These cells make other cells that cause inflammation and damage the joints.
The scientists believe that if they can stop these special cells from working, they can help people with the disease feel better.
Japanese researchers identified immune 'hubs' in joints of rheumatoid arthritis patients.
Stem-like Tph cells reside in the immune hubs and activate B cells.
Effector Tph cells leave the hubs, causing inflammation and joint damage.
Targeting stem-like Tph cells may lead to more effective treatments.
The research was published in the journal Science Immunology.
