|February 1, 1977
Summary
Monkey lymphocytes showed lower titers in rosette inhibition assays compared to human cells. These results suggest human lymphocytes are more reliable for predicting antithymocyte globulin efficacy in skin graft prolongation.
Area of Science:
- Immunology
- Transplantation Biology
Background:
- Antithymocyte globulin (ATG) is crucial for preventing transplant rejection.
- The rosette inhibition assay is a method to assess ATG efficacy.
- Evaluating reliable lymphocyte sources for this assay is important.
Purpose of the Study:
- To compare the effectiveness of human and monkey lymphocytes in a modified rosette inhibition assay.
- To determine if monkey lymphocytes can reliably predict skin graft prolongation in monkeys.
Main Methods:
- A modified rosette inhibition assay was performed.
- Human and monkey lymphocytes were used.
- Results were compared against antithymocyte globulin preparations.
Main Results:
- Monkey lymphocytes consistently yielded lower titers compared to human lymphocytes.
- Assays using monkey lymphocytes showed poorer correlation with skin graft prolongation in monkeys.
- Human lymphocyte assays demonstrated better predictive value in prior studies.
Conclusions:
- Human lymphocytes are more suitable for rosette inhibition assays assessing antithymocyte globulin.
- Monkey lymphocytes may underestimate the efficacy of antithymocyte globulin in predicting graft survival.
