|January 1, 1979
Summary
A new method simultaneously counts human T cells and B cells using sheep red blood cells and immunobeads. This simple, reproducible technique also identifies double-marker lymphocytes for potential clinical applications.
Area of Science:
- Immunology
- Cell Biology
- Clinical Diagnostics
Background:
- Accurate enumeration of lymphocyte subpopulations is crucial for immunological assessment.
- Existing methods may be complex or lack the ability to identify dual-marker cells.
Purpose of the Study:
- To develop a simultaneous method for enumerating human T cells and B cells.
- To introduce a technique capable of identifying lymphocytes with both T and B cell markers.
Main Methods:
- Lymphocytes were mixed with sheep red blood cells and immunobeads.
- T cells were identified via rosette formation with AET-treated sheep red blood cells.
- B cells were identified using immunobeads coated with antibodies against immunoglobulin light chains.
Main Results:
- The method allows for simultaneous enumeration of T cells and B cells.
- Detection of double-marker lymphocytes (possessing both T and B cell characteristics) was achieved.
- Three distinct rosette types were distinguishable via light microscopy.
Conclusions:
- This novel technique offers a simple, convenient, and reproducible approach for lymphocyte subpopulation analysis.
- The method's ability to identify double-marker cells suggests potential value in clinical settings.
