RNA seq experiment of Treg cells isolated from peripheral blood of patients with pulmonary sarcoidosis compared to Treg cells from peripheral blood of healthy individuals

Sarcoidosis is manifested by an exaggerated Th1 response on one hand, combined with high numbers of dysfunctional Treg cells on the other3. Moreover, it has been shown that Treg cells in patients with pulmonary sarcoidosis (PS) have impaired immunosuppressive function, survival and enhanced apoptotic susceptibility towards Fas ligand (CD95L)4. However, the molecular background for the impairment of the Treg function in PS has not been elucidated.
