Splenocyte

Splenocytes are white blood cells that reside in the spleen and are involved in functions of the spleen, such as filtering blood and the immune response.

[2] The spleen is split into red and white pulp regions with the marginal zone separating the two areas.

The red pulp is involved with filtering blood and recycling iron, while the white pulp is involved in the immune response.

MZ macrophages remove some types of blood-borne bacteria and viruses.

[2] MZ B and dendritic cells are involved in antigen processing and presentation to lymphocytes in the white pulp.
