After identifying that a two-allele leucocyte antigen group had an influence on histocompatibility and observing the induction of hyper-sensitivity to skin grafts following injection of leucocyte fractions, Dausset developed a system for grouping leucocyte antigens on the basis of histocompatibility.

In 1999 researchers in Glasgow University found that an oxidised derivative of thymosin ? 4 ( the sulfoxide, in which an oxygen atom is added to the methionine near the N-terminus ) exerted several potentially anti-inflammatory effects on neutrophil leucocytes.

This causes a reduction in both ICAM-1 expression on cell surfaces and a selective reduction in ICAM-1 mRNA . In particular, it down-regulates ICAM-1 on vascular endothelial cells, inhibiting leucocyte adherence, migration and activation.

Cord blood can be harvested from the Umbilical Cord of a child being born after preimplantation genetic diagnosis ( PGD ) for human leucocyte antigen ( HLA ) matching ( see PGD for HLA matching ) in order to donate to an ill sibling requiring HSCT.

Not only are the erythrocytes affected by hemolysins, but there are also some effects among other blood cells, such as leucocytes ( white blood cells ) . " Escherichia coli " hemolysin is potentially cytotoxic to monocytes, lymphocytes and macrophages, leading them to autolysis and death.

CysLTR1 activation is also associated in animal models with decreasing the Blood-brain barrier ( i . e . increasing the permeability of brain capillaries to elements of the blood's soluble elements ) as well as promoting the movement of leukocytes for the blood to brain tissues; these effects may increase the development and frequency of Epileptic seizure as well as the entry of leucocyte-borne viruses such as HIV-1 into brain tissue.

In 1955 St�helin rediscovered in Manfred L . Karnovsky's laboratory at the Department of Bacteriology and Immunology, Harvard Medical School, Boston the respiratory burst in leucocytes ( H . St�helin, E . Suter, M . L . Karnovsky J, " Studies on the interaction between phagocytes and tubercle bacilli " Exp . Med . 104, 121-136 & 137-150, 1956; 105, 265-277, 1957 ).

In 1955, St�helin rediscovered the respiratory burst in leucocytes in Manfred L . Karnovsky's laboratory at the Department of Bacteriology and Immunology, Harvard Medical School, Boston, U . S . A . His experiments stirred the interest of Karnovsky, who was at the time unaware of this metabolic phenomenon ( which had first been described more than twenty years earlier in 1933 by C . W . Baldridge and R . W . Gerard ).
