Impaired NK-cell migration in WAS/XLT patients: role of Cdc42/WASp pathway in the control of chemokine-induced beta2 integrin high-affinity state.

abstract：:One hundred thirty-eight patients with hairy cell leukemia were randomized to receive either a dose of 2.0 megaunits (MU)/m2 or a 10-fold lower dose of 0.2 MU/m2 of a highly purified natural alpha-interferon, administered daily for 28 days followed by a three times a week schedule. Ninety-seven of these patients had p...
