| Title | Impaired TIGIT expression on B cells drives circulating follicular helper T cell expansion in multiple sclerosis |
Results of multiple sclerosis :
| Expression | up-regulation |
| Risk type | Disease risk |
| Result | Most striking was the impaired TIGIT expression on MS-derived B cells mediated by dysregulation of the transcription factor TCF4. Activated circulating Tfh cells (cTfh cells) expressed CD155, the ligand of TIGIT , and TIGIT on B cells revealed their capacity to suppress the proliferation of IL -17–producing cTfh cells via the TIGIT/CD155 axis |
| Mechanism/Pathway | Here, we performed comprehensive analyses of CD40 ligand– (CD40L -) and IL -21–stimulated memory B cells from patients with MS and healthy age-matched controls, modeling the help of follicular helper T cells (Tfh cells), and found a differential gene expression signature in multiple B cell pathways. |
