Macrophage depletion using Cytodex.

E C Ren

    Journal of Immunological Methods
    |January 1, 1982

    Summary
    This summary is machine-generated.

    Cytodex microcarrier beads effectively removed macrophages from mouse spleen cells. The remaining cells showed reduced T cell responses but could be restored by adding back the removed macrophages.

    Area of Science:

    • Immunology
    • Cell Biology

    Background:

    • Macrophages play a crucial role in immune responses.
    • Depleting specific cell populations is essential for studying immune cell function.

    Purpose of the Study:

    • To evaluate Cytodex microcarrier beads as a method for macrophage depletion from mouse spleen cell populations.
    • To assess the impact of macrophage depletion on T cell proliferation and other immune cell responses.

    Main Methods:

    • Mouse spleen cells were incubated with Cytodex microcarrier beads.
    • Non-adherent cells were collected and their viability and proliferative responses were measured.
    • Adherent cells (macrophages) were recovered from beads using trypsinization.

    Main Results:

    Related Experiment Videos

  • Cytodex beads successfully depleted macrophages from spleen cell cultures.
  • Non-adherent cells exhibited reduced proliferative responses to T cell mitogens like phytohemagglutinin and concanavalin A.
  • The mitogenic response of depleted cells was restored by adding back the recovered macrophages.

    • Conclusions:

    • Cytodex microcarrier beads provide an effective method for macrophage depletion.
    • Macrophages are critical for restoring T cell mitogenic responses in mouse spleen cell populations.
