Abstract in brief

  • This study investigates how peripheral CD8 T cells, particularly those with a terminal effector signature expressing Granzyme B (GzmB), contribute to the progression of multiple sclerosis (MS) from relapsing-remitting (RRMS) to secondary progressive (SPMS), highlighting their potential as diagnostic markers.
  • Researchers used techniques like single-cell RNA sequencing, flow cytometry, and T cell receptor sequencing to examine the heterogeneity, dynamics, and clonal expansion of CD8 T cells in MS patients, finding an increase in activated, differentiated CD8 T cells with GzmB in SPMS.
  • The transcription factor Tbet was shown to regulate GzmB expression in CD8 T cells, and higher GzmB levels correlated with greater disability and disease progression, suggesting that GzmB-expressing CD8 T cells could serve as a diagnostic marker to distinguish SPMS from RRMS with high accuracy.
