One hypothesis put forward to explain resistance to anti-TNFα therapy is an ascendant effect of dysregulated regulatory T cells and increased Th17 responses following TNFα blockade. Previous studies have demonstrated that TNFR2 is critical for stabilisation and suppressive function of regulatory T cells2,3. However, TNFR2 also activates pro… Show more
