Inclusion Criteria

Males and females aged 18-45 years
- Ability to provide written informed consent
- Mentally stable and able to comply with the procedures of the Protocol for the duration of the study, including follow-up visits and examinations scheduled
- T1D new onset (diagnosis of diabetes within 180 days prior to enrollment).
- Function beta cell residual (C-peptide fasting> 0.3 ng / mL in plasma glucose levels> 70 mg / dL and =200 mg / dL).
- Positivity for at least one of the following autoantibodies typically associated with T1D: anti-GAD, anti-IA-2, anti ZnT8, IAA. A person who is positive for IAA and negative for other autoantibodies is not admissible if used insulin for more than 7 days.
- Ongoing treatment with insulin, or has required insulin therapy (for 7 days) for diabetes at some time between the date of diagnosis and recruitment
- Incompatibility for MHC class IA and B and compatibility for MHC class II DR with the donor of islet

- Use of investigational drugs within 4 weeks of enrollment.
- The administration of live attenuated vaccine within 2 months thereafter
- Any medical condition that, in the opinion of the investigator, would interfere with the safe participation in the study.
- Treatment with any immunosuppressive regimen at enrollment
