TACI (Transmembrane Activator and CAML Interactor) is a receptor encoded by the TNFRSF13B gene that belongs to the TNF receptor superfamily. TACI is primarily expressed on B cells and plays critical roles in B cell function, antibody production, and immune homeostasis. TACI binds BAFF and APRIL ligands, which are important for B cell survival and maturation. In the central nervous system, TACI is expressed on certain glial cells and may have roles in neuroinflammation. TACI mutations are associated with common variable immunodeficiency (CVID) and autoimmune conditions. The role of TACI in neurodegeneration is emerging - it may influence B cell-mediated inflammation in autoimmune encephalitis and potentially modulate neuroinflammation in Alzheimer's and Parkinson's diseases. TACI represents a potential immunological therapeutic target.
TACI (TNFRSF13B) encodes a member of the TNF receptor superfamily that plays crucial roles in B cell function and immunoglobulin class switching. While primarily studied in the immune system, TACI is expressed in certain neuronal populations and may play roles in neuroimmune interactions. TACI binds BAFF and APRIL cytokines to modulate B cell survival and function.
Expressed in B cells and some subsets of neurons. The CNS expression is relatively limited compared to immune tissues, but may be upregulated in neuroinflammatory conditions.
| Disease | Variants | Inheritance | Mechanism |

| Common Variable Immunodeficiency | A181E, C104R | Autosomal dominant | Impaired B cell function |
| ALS | Possible altered expression | Risk factor | Potential role in neuroimmune crosstalk |
