Eligibility criteria:

        Inclusion Criteria:

          1. Recipient Inclusion criteria (within 28 days of this protocol's lymphodepleting
             conditioning regimen and after donor and recipient consent-signing)

          2. Diagnosis of CD22+ acute lymphoblastic leukemia that is a. refractory to therapy or b.
             in second or greater relapse without other standard therapeutic options

          3. Patient may have been the recipient of an allogeneic hematopoietic stem cell
             transplant; however; there must be no evidence of Graft-versus-host disease (GVHD)

          4. Off prednisone or other immunosuppressive medications for at least 3 days prior to
             both the lymphodepleting regimen and the NK infusion

          5. Zubrod performance scale </= 2 or Lansky performance scale >/= 60

          6. Adequate renal function defined as: Serum creatinine (Cr), for adults </= 2 mg/dL, for
             children </= 2 mg/dL or </= 2 times upper limit of normal (ULN) for age (whichever is
             less). If abnormal renal function, then Cr clearance >/= 60 mL/min/1.73 m^2

          7. Adequate liver function defined as: Total bilirubin </= 2 mg/dL and serum
             glutamic-pyruvic transaminase (SGPT)/ alanine transaminase(ALT) </= 5 * ULN for age
             (unless Gilbert's disease or abnormal liver function due to primary disease)

          8. Pulmonary symptoms controlled by medication and pulse oximetry >/= 92% room air

          9. Negative serum test to rule out pregnancy within 2 weeks prior to registration in
             females of childbearing potential (non childbearing is defined as greater than one
             year post-menopausal or surgically sterilized

         10. Requirement of sexually active females and males to use any form of contraception
             considered effective and medically acceptable by the Investigator. [Acceptable forms:

             intrauterine device (IUD), male or female condom with spermicidal gel, a diaphragm, a
             sponge, and/or cervical cap)]

         11. Negative serology for human immunodeficiency virus (HIV)

         12. Donor must be related to recipient and is predicted to be alloreactive based upon the
             presence of the relevant KIR genes and incompatibility with the recipient for HLA C or
             Bw antigens

         13. Donor must have infectious disease marker testing [Hepatitis B, C, HIV, CMV, Syphilis
             (RPR), Chagas, HTLV, and West Nile Virus] and CBC differential and platelet studies
             that meet standard medical eligibility criteria for allogeneic blood stem cell
             donation within 7 days of apheresis

         14. Donor, if a female of childbearing potential (non-childbearing is defined as greater
             than one year post-menopause or surgically sterilized), must have a negative serum
             test to rule out pregnancy within 14 days of apheresis

         15. Donor must meet standard medical eligibility criteria for allogeneic stem cell
             donation

        Exclusion Criteria:
