11. HLA _ human leucocyte antigen _ genes can produce proteins that appear on the surface of white blood cells. 12. Persons having the HLA-DR4 type of human leucocyte antigen appear to have a higher risk of PMR. 13. So, the leucocyte no . in their bodies will also fall, making them more prone to pathogens. 14. HLA, or human leucocyte antigen, genes can produce proteins that appear on the surface of white blood cells. 15. Because they outnumber by far the leucocytes they need to be removed to do a FACS analysis of the Basophils. 16. Fleck's research during these years focused on the question of the behavior of leucocytes in infectious and stress situations. 17. IL-1RN, which decreases leucocyte invasion of the cornea and suppresses neovascularization, both of which can help preserve vision. 18. The album is their second released posthumously, after Leucocyte ( album ), as the pianist Esbj�rn Svensson died in June 2008. 19. It was recorded during the same sessions of the recording of Leucocyte , whilst the Swedish trio were touring around Asia and Australia. 20. For example, fully understanding the key set of genes to the human leucocyte antigen has been described as " the Rosetta Stone of immunology ".
