Different ratios of activated effector cells (CD25-depleted spleen cells) to CD4 +CD25 +cells were tested in our cotransfer experiments.

These include spleen cells and macrophages, cells that engulf invading viruses, bacteria or foreign cells and chop them into pieces.

If the protein was not stimulated, the T cell would not respond to the fragments of foreign proteins that the spleen cell was displaying on its surface.

Monoclonal antibodies are typically made by fusing myeloma cells with the spleen cells from a mouse that has been immunized with the desired antigen.

Unfused spleen cells cannot grow indefinitely because of their limited life span.

Assessment of cytokine production by spleen cells in vitro Spleens were obtained 1 week after the third injection with PG, as described elsewhere [ 4].

It causes genetic damage: chromosomal abnormalities increased in bone marrow and spleen cells when mice were exposed to cypermethrin.

Flow cytometry Flow cytometry was performed on freshly isolated spleen cells.

Leukocytes, hepatocytes and most spleen cells actively phagocytose particulate matter, which makes the parasite's entry into the cell easier.

A report from NIH was released on November 23, 2006 in Science confirming the participation of spleen cells in reversing end-stage diabetes.
