A key role for T-cell TET3 in chronic GVHD; a BTK inhibitor for ITP; co-inhibition of pre-TCR and IL-7R pathways in a T-ALL patient subset

In this week's episode, we' ll learn about how TET3 has a key role in GVHD. In mice, a deficiency of Tet3 in donor T cells inhibited pathogenic immunoglobulin class switching and suppressed lung fibrosis. Accordingly, TET3 may be a new therapeutic target in chronic GVHD. After that: rilzabrutinib, a BTK inhibitor for ITP. In a randomized, placebo-controlled trial, treatment produced rapid and durable platelet responses, with acceptable safety, in adults with immune thrombocytopenia who had failed multiple previous therapies. Finally: exploring pre-TCR surface expression patterns in T-cell ALL. Co-inhibition of the interleukin-7 receptor and pre-T cell receptor pathways may play a therapeutic role for a subset of T-lymphoblastic leukemias.
