WNK1 kinase balances T cell adhesion versus migration in vivo
The kinase WNK1 is part of a pathway that controls the uptake of ions into kidney cells. Tybulewicz and colleagues show that a related pathway involving WNK1 also operates in T cells, in which it negatively regulates adhesion and positively regulates migration. Adhesion and migration of T cells are...

Summary: | The kinase WNK1 is part of a pathway that controls the uptake of ions into kidney cells. Tybulewicz and colleagues show that a related pathway involving WNK1 also operates in T cells, in which it negatively regulates adhesion and positively regulates migration.
Adhesion and migration of T cells are controlled by chemokines and by adhesion molecules, especially integrins, and have critical roles in the normal physiological function of T lymphocytes. Using an RNA-mediated interference screen, we identified the WNK1 kinase as a regulator of both integrin-mediated adhesion and T cell migration. We found that WNK1 is a negative regulator of integrin-mediated adhesion, whereas it acts as a positive regulator of migration via the kinases OXSR1 and STK39 and the ion co-transporter SLC12A2. WNK1-deficient T cells home less efficiently to lymphoid organs and migrate more slowly through them. Our results reveal that a pathway previously known only to regulate salt homeostasis in the kidney functions to balance T cell adhesion and migration. |
