The present invention comprises screening for various unmodified and modified α1PI's which are useful in the treatment of abnormalities in the number of cells of myeloid or lymphoid lineage that are associated with Human Immunodeficiency Virus-1 (HIV-1) infection, microbial infection, leukemia, solid tumor cancers, atherosclerosis, autoimmunity, stem cell transplantation, organ transplantation, and other diseases affected by cells of the immune system. The interaction of α1PI with its receptors, cell surface Human Leucocyte Elastase (HLEcs) and Lipoprotein Receptor-related Protein (LRP), influences the level of cells of different lineages. Genetic and proteolytic modification of α1PI is used to target these receptors to increase or decrease specific cell populations, as needed, in the various disease states."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Therapeutic use for α1 proteinase inhibitor in hematopoiesis","description":"A previously unrecognized fundamental property of α1PI is to regulate the phenotypic composition of circulating and tissue-associated cells derived from hematopoietic stem cells.
