Conditions
Brief summary
The purpose of this study was to explore the regulatory and effector T cell-related immune mechanisms associated with the development of graft-versus-host disease (GVHD) after allogeneic hematopoietic cell transplantation (HCT) using patient-derived derivatives, thereby establishing the basis for GVHD prevention strategies.
Interventions
Sampling 1. patient 1. Peripheral blood samples in a volume of 25 cc will be collected before HCT and 2 weeks after HCT, and peripheral blood samples in a volume of 20 cc will be collected 4 weeks, 3 months, 6 months, and 12 months after HCT. 2. If GVHD occurs, additional blood sample (20 cc) will be collected. 3. In case of organ-specific GVHD including skin, gut, liver, muscle, etc., tissue samples from biopsy will be obtained for further analysis. 2. donor a. Peripheral blood samples in a volume of 20 cc will be collected before HCT

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Immune cell phenotype analysis | before HCT and 2 weeks after HCT, 4 weeks, 3 months, 6 months, and 12 months after HCT. If GVHD occurs | Immune cell phenotypes will be analyzed by examining immunophenotypic changes in regulatory T cells and acquired immune cells using a 6-color flow cytometer. For skin and intestinal graft-versus-host disease tissues, multi-color imaging techniques (e.g., Polaris, CODEX) will be utilized to obtain spatial information and the pathogenic potential of various immune cells within the tissue. |
