The paper investigates how loss of PTPRB function affects VEGFR1 activation in tumors, finding that PTPRB deficiency leads to ligand-independent dimerization and sustained phosphorylation of VEGFR1, promoting tumor vascularization.

The paper investigates how extracellular K+ and Na+ ions differentially regulate TCR signaling by modulating ZAP-70 recruitment, affecting T cell function and development.
