Allospecificity of Activated T Cells Grown From Endomyocardial Biopsies From Heart Transplant Patients
Key result
IL-2 successfully drives proliferation of heart transplant biopsy lymphocytes exhibiting donor-specific allospecificity.
- n=4
Why the study?
The functional characteristics and allospecificity of lymphocytes infiltrating human heart allografts were not well characterized.
Comparison
Lymphocyte cultures grown in IL-2 medium with autologous feeder cells
Design
Preclinical study culturing lymphocytes from biopsies

Implication
Enables mechanistic analysis of cardiac rejection; leaves open whether biopsy-derived T-cell cultures can inform clinical management.

P
Population
Four heart transplant recipients who provided 13 endomyocardial biopsies during a posttransplant period of less than two months.
E
Exposure
Lymphocyte culture in interleukin-2 (IL-2)-containing medium supplemented with irradiated autologous peripheral blood lymphocytes as feeder cells
O
Outcome
Functional characteristics, phenotypes, and allospecificity of cultured T cellssurrogate
This study demonstrates the feasibility of growing functionally active, donor-specific T cells from heart transplant biopsies, enabling detailed analysis of cellular rejection mechanisms.
Cite This Study
Zeevi et al. (1986) studied Heart transplant (n=4). Endomyocardial biopsy lymphocyte culture was evaluated on Feasibility of growing functionally active T cells and their allospecificity. Lymphocytes cultured from 13 endomyocardial biopsies of 4 heart transplant recipients successfully proliferated in response to IL-2 and showed donor-specific allospecificity.
