A previously unrecognized fundamental property ofα1PI is to regulate the phenotypic composition of circulating and tissue-associated cells derived from hematopoietic stem cells. The present invention comprises screening for various unmodified and modifiedα1PI's which are useful in the treatment of abnormalities in the number of cells of myeloid or lymphoid lineage that are associated with HW-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 ofα1PI with its receptors, HLECS and LRP, influences the level of cells of different lineages. Genetic and proteolytic modification ofα1PI is used to target these receptors to increase or decrease specific cell populations, as needed, in the various disease states.
