Abstract: A previously unrecognized fundamental property of ?1PI 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 modified ?1PI'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 ?1PI 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 ?1PI is used to target these receptors to increase or decrease specific cell populations, as needed, in the various disease states.

Abstract: A method for modulation of plasma membrane associated Human Leukocyte Elastase (HLE) to inflammatory states by interaction of HLE with an antagonist to inhibit HLE and thereby interruption in plasma associated events (e.g. HIV disease progression, bacterial infections and autoimmune diseases), which are responsive/sensitive to such inflammation. The antagonist suitable for use in this invention is designed to interact with each of the catalytic triad of the HLE plasma membranes protein and the lipid interactive amino acids of the HLE plasma membrane protein.

The present invention comprises screening for various unmodified and modified ?1PI'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 of ?1PI with its receptors, HLECS and LRP, influences the level of cells of different lineages.

Abstract: The present invention is directed to protamine-reactive, IgM antibodies, and their uses in prognosis, diagnosis, and therapy. In a specific embodiment, the invention relates to low affinity binding, protamine-reactive serum IgM antibodies. In particular, such antibodies can recognize a sequence comprising four arginyl residues, including a triplet, within a six amino acid residue sequence. Such antibodies may be natural antibodies (i.e., not induced). A low affinity subset of serum protamine-reactive IgM antibodies may be assayed for prognosis or diagnosis of AIDS. Such antibodies are detectable in sera of normal subjects and HIV-infected individuals who subsequently exhibit a significant period of latency, but are absent or deficient in sera of individuals diagnosed with AIDS and sera of HIV infected individuals, who though asymptomatic at the time of the sampling, proceed to AIDS within a relatively short time.

Abstract: An isolated human natural IgM antibody immunoreactive with an epitope present on HIV-1 Tat protein is provided. Additionally, a method for the prognosis or diagnosis of AIDS in an individual infected with HIV including the steps of:obtaining a body fluid from the individual,detecting or measuring natural human IgM antibodies in the body fluid of the individual and determining a .DELTA.20-.DELTA.2 value, andcomparing the .DELTA.20-.DELTA.2 value obtained from the individual with a .DELTA.20-.DELTA.2 value obtained from clinically normal, non-HIV infected humans,wherein the individual has AIDS or will progress to AIDS within about two years if the individual's .DELTA.20-.DELTA.2 value is significantly decreased relative to the .DELTA.20-.DELTA.2 value obtained from the clinically normal humans, is provided.
