Abstract: The present invention relates to a biologically active serum-derived composition of matter (SDF), having a low molecular weight, being electrically charged at acidic pH and having absorption at 280 nm. The molecular weight of said SDF was determined by electron spray mass spectrometry and is of 316 Da. SDF of the present invention or its complex with ceruloplasmin (CP) have several therapeutic properties. For example, SDF or its complex with CP is capable of inducing terminal cell differentiation of leukemic cells, which as a result, may lose their ability to proliferate and their ability for self cell renewal. Further, SDF or the complex with CP is capable of stimulating the proliferation of early, normal progenitor cells and inhibiting enhanced angiogenesis. In addition, SDF or its complex with CP is capable of ex vivo expanding normal stem and progenitor cells.

Abstract: The present invention features a method of inducing donor-specific tolerance in a host. Tolerogenic treatments of the present invention may be administered to a host prior to transplantation of donor-derived materials. The tolerogenic treatment involves (1) administering an immunosuppressive agent to a host mammal in a non-myeloablative regimen sufficient to decrease, but not necessarily to eliminate, the host mammal's functional T lymphocyte population; (2) infusing donor antigens from a non-syngeneic donor into the host mammal; (3) eliminating those host T lymphocytes responding to the infused donor antigens using a non-myeloablative dose of lymphocytotoxic or tolerizing agent; and (4) administering donor hematopoietic cells to the host mammal. Donor lymphoid cells used for cell therapy of a host mammal can be depleted of host specific immunological reactivity by methods essentially similar to those use for tolerizing a host mammal prior to transplantation.

Abstract: A method for administering the HAV vaccine to a subject by absorption through a mucosal tissue, particularly through the mucosa of the rectum. The method of the present invention enables the HAV vaccine to be administered to the subject rectally, for example as a suppository or other rectal dosage form, and to successfully immunize the subject against HAV. Thus, the present invention overcomes problems of background art methods of administration, such as systemic administration by injection for example, which require needles, and which are difficult and expensive to perform.

Abstract: Methods have been discovered for treating minimal residual disease following removal of most or a substantial fraction of malignant cells from a cancer patient. An autologous stem cell transplant is performed on the patient. Following partial hematopoiesis recovery, the patient is infused with allogeneic peripheral blood lymphocytes, either alone or in combination with in vivo or in vitro cytokine. The infused allogeneic lymphocytes engender an anti-malignant cell response and can be instrumental in prevention of disease relapse.
