In mice with a disease similar to lupus, removing the TACI gene lowers autoantibody levels, restores normal T follicular helper cell function, prevents kidney damage, and keeps plasma cell numbers...
Mechanism
Synthesis from 1 study
Removing TACI cuts off signals that keep harmful immune cells alive and overactive. This stops the production of antibodies that attack the body, calms down the immune cells that drive the attack, protects the kidneys from damage, and leaves the body’s ability to fight infections unchanged.
Most probable mechanism
Removing TACI stops signals that keep abnormal immune cells alive and active, which reduces harmful antibodies, calms overactive helper cells, prevents kidney damage, and keeps protective immunity intact.
TACI receptor absence prevents BAFF and APRIL ligands from delivering survival signals to autoreactive B cells
Loss of TACI signaling reduces NF-κB pathway activation in B cells and plasma cells
Reduced NF-κB activity decreases production of immunosuppressive cytokines and checkpoint molecules
Lower levels of immunosuppressive signals restore normal T follicular helper cell expansion and germinal center regulation
Normalized T follicular helper cell activity reduces differentiation of autoreactive B cells into autoantibody-producing plasma cells
Decreased autoantibody production prevents immune complex deposition and inflammation in kidney tissue
Plasma cell numbers return to baseline without compromising protective antibody responses
