JCI - Addiction of primary cutaneous Ξ³Ξ΄ T cell lymphomas to JAK/STAT signaling

some GD T cell lymphomas are addicted to JAK-STAT signaling and relapse with new JAK-STAT mutations, much like melanomas to BRAF inhibitors. ? new approach ? to treating these aggressive diseases. cell of origin (GD cells) important but unclear why. stay tuned for more.

Dynamic STING repression orchestrates immune cell development and function Repression of STING expression in neutrophils and T lymphocytes is required for immune homeostasis and tumor response.

New #ScienceImmunology research involving mice and human tissues demonstrates how different immune cell types modify expression of stimulator of interferon genes (STING) to support their normal development and function. scim.ag/4idx7wn
