Activated HLA-DR+CD38+ Effector Th1/17 Cells Distinguish Crohn’s Disease-associated Perianal Fistulas from Cryptoglandular Fistulas

Overall, proliferating activated HLA-DR+CD38+ effector Th1/17 cells distinguish CD-associated from cryptoglandular perianal fistulas and are a promising biomarker in blood to discriminate between these 2 fistula types.
