Desferroxamine inhibits lectin-stimulated proliferation of human lymphocytes. Inhibition is not due to toxic effect of the drug as it could be completely reversed by iron. It is found that the drug impairs the expression of both the total and high-affinity interleukin-2 (IL-2)-binding receptors on lymphoid cells in response to the mitogen phytohaemagglutinin. IL-2 production by mitogen-stimulated T4+T8- and T8+T4- populations is also markedly reduced by desferroxamine treatment. Decreased secretion of macrophage inhibition factor and macrophage activation factor is also observed as the result of the lymphocytes of the helper/delayed hypersensitivity subset being exposed to the drug. Collectively, our results suggest that desferroxamine interferes with the early activation events of human lymphokine-producing lymphocytes.

UI	MeSH Term	Description	Entries
D007963	Leukocytes, Mononuclear	Mature LYMPHOCYTES and MONOCYTES transported by the blood to the body's extravascular space. They are morphologically distinguishable from mature granulocytic leukocytes by their large, non-lobed nuclei and lack of coarse, heavily stained cytoplasmic granules.

D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008222	Lymphokines	Soluble protein factors generated by activated lymphocytes that affect other cells, primarily those involved in cellular immunity.	Lymphocyte Mediators,Mediators, Lymphocyte
D011971	Receptors, Immunologic	Cell surface molecules on cells of the immune system that specifically bind surface molecules or messenger molecules and trigger changes in the behavior of cells. Although these receptors were first identified in the immune system, many have important functions elsewhere.

D015375	Receptors, Interleukin-2	Receptors present on activated T-LYMPHOCYTES and B-LYMPHOCYTES that are specific for INTERLEUKIN-2 and play an important role in LYMPHOCYTE ACTIVATION. They are heterotrimeric proteins consisting of the INTERLEUKIN-2 RECEPTOR ALPHA SUBUNIT, the INTERLEUKIN-2 RECEPTOR BETA SUBUNIT, and the INTERLEUKIN RECEPTOR COMMON GAMMA-CHAIN.
