Scientists Discover Immune Hubs Driving Joint Damage in Arthritis
Scientists have discovered secret immune centers inside joints of people with rheumatoid arthritis (RA).
These centers are like factories producing immune cells that cause joint damage.
There are two main types of these cells: stem-like and effector cells.
The stem-like cells live in the factories, and the effector cells cause inflammation.
The scientists found that the factories make more of the damaging cells.
If they can stop the factories, they might be able to help people with RA feel better.
Scientists identified immune 'hubs' driving joint damage in rheumatoid arthritis (RA).
Researchers found two types of Tph cells: stem-like and effector.
Stem-like Tph cells reside in immune hubs within inflamed joints.
These hubs help stem-like Tph cells develop into effector Tph cells that cause inflammation.
Targeting stem-like Tph cells could offer a new therapeutic strategy for RA.
