In vivo depletion of CD4- and CD8-specific T cells

Area of Science:

• Immunology
• Cell Biology

Background:

• Studying T cell subpopulations (CD4+ and CD8+) is crucial for understanding immune responses.
• Existing methods for T cell depletion can be complex or require specialized reagents.

Purpose of the Study:

• To provide a standardized protocol for in vivo depletion of CD4 and CD8 T cells in mice.
• To enable researchers to investigate the functional roles of specific T cell subsets in immune responses.

Main Methods:

• Harvesting anti-CD4 or anti-CD8 monoclonal antibodies from hybridomas.
• Purifying monoclonal antibodies (preferably IgG) and administering them intraperitoneally to mice.
• Verifying T cell depletion via flow cytometry analysis of lymphoid tissues.

Main Results:

• Successful generation and purification of monoclonal antibodies for T cell depletion.
• Demonstrated efficacy of the antibody treatment in reducing specific T cell populations in vivo.
• Established a reliable method for T cell subset depletion in mice.

Conclusions:

• The described protocol offers a robust method for in vivo T cell depletion.
• This technique facilitates the study of T cell subset functions in various immune contexts.
• Repeated antibody administration ensures sustained depletion for long-term studies.
