| Abstract: | Preparations enriched in human blood B lymphocytes are able to take up polyamines efficiently. Uptake by T cells is barely detectable. Human non-circulating B cells (from tonsils) have a much lower ability to take up polyamines, as do mixed populations of bovine lymph nodes. B cells contain a higher amount of endogenous polyamines and show higher ornithine decarboxylase activity than T cells. |
