Abstract: The present disclosure relates generally to compositions and methods of detecting viable embryos for implantation based upon detection and/or quantification of levels or concentrations of the preimplantation factor (PIF) in an embryo culture medium sample.

Abstract: The disclosure relates to a pharmaceutical composition comprising any one or combination of PIF peptides or analogs or pharmaceutically acceptable salts thereof. Methods of treating autoimmune disease using the one or a combination of PIF peptide or analogs thereof or pharmaceutically acceptable salts thereof is also disclosed.

Abstract: This application describes compounds that are preimplantation factor (PIF) peptides, mimetics thereof, pharmaceutically acceptable salts thereof, or combinations thereof. This application also describes the use of those compounds for treatment and prevention of non-alcoholic steatohepatitis (NASH), liver fibrosis and non-alcoholic fatty liver disease (NAFLD).

Abstract: Embodiments are directed to methods of examining preimplantation factor (PIF) binding to a subject's circulating immune cells as a marker for immune dysregulation. Some embodiments are directed to methods of detecting a level of immune dysregulation sufficient to cause recurrent pregnancy loss (RPL), methods of detecting a level of immune dysfunction sufficient to cause endometriosis, and methods of detecting a level of immune dysfunction comprising administering an effective amount of PIF or an analog thereof, and examining its binding to circulating immune cells. Within those methods, an about twenty percent change in PIF binding to a subject's circulating immune cells indicates a level of immune dysfunction.

Abstract: Embodiments are directed to a method of treating acute radiation syndrome comprising administering to a subject following exposure to radiation a PIF peptide. Some embodiments describe a method of treating acute radiation syndrome following radiation exposure comprising transplanting bone marrow that has been exposed to a PIF peptide prior to transplantation into a subject. Other embodiments describe a method of increasing engraftment of a transplanted organ, tissue, or cell by pre-exposing the organ, tissue, or cell to a PIF peptide.

Abstract: This application describes compounds that are preimplantation factor (PIF) peptides, mimetics thereof, pharmaceutically acceptable salts thereof, or combinations thereof. This application also describes the use of those compounds for improving transplant tolerance, for restoring endocrine function, and for the treatment of transplant recipients of partial endocrine tissue grafts.

Methods of treating autoimmune disease using the one or a combination of PIF peptide or analogs thereof or pharmaceutically acceptable salts thereof is also disclosed.

Abstract: The disclosure relates to a pharmaceutical composition comprising any one or combination of PIF peptides or analogs or pharmaceutically acceptable salts thereof. Methods of treating cellular neurodamage or neurotrauma to the peripheral or central nervous system using the one or a combination of PIF peptide or analogs thereof or pharmaceutically acceptable salts thereof is also disclosed.

Abstract: Pre-implantation factor (PIF) may be used to treat intracellular damage. Aspects of the invention are directed to a method of treating intracellular damage comprising administering PIF to a subject in need thereof. Some aspects may be directed to methods of increasing cytokine secretion in response to intracellular damage comprising administering PIF to a subject in need thereof. The intracellular damage may be a result of a disease such as Listeria monocytogenes infection, malaria, Lyme disease, cardiovascular disease, duodenal peptic ulcer, atherosclerosis, peritonitis or tuberculosis. In some aspects, a method of treating tuberculosis is disclosed, comprising administering PIF to a subject in need thereof. In some aspects, a method of treating atherosclerosis is disclosed, comprising administering PIF to a subject in need thereof. In some aspects, a method of treating peritonitis is disclosed, comprising administering PIF to a subject in need thereof.

Abstract: A novel class of embryo derived peptides are described (Preimplantation factor) that were generated synthetically and were tested on peripheral blood immune cells and shown to block activated but not basal immunity, inhibiting cell proliferation and creating a TH2 type cytokine bias, in addition PIF enhance endometrial receptivity by increasing adhesion molecules expression. PIF biological activity appears to be exerted by specific binding to inducible receptors present on the several white cell lineages. PIF peptides, which are immune modulators therefore may have diagnostic and non toxic therapeutic applications in improving fertility, reducing pregnancy loss as well may be useful when administered for the treatment of autoimmune diseases and for prevention xenotransplants rejection.
