Abstract: The present invention relates generally to the fields of immunology and molecular biology, and particularly to a method for treating hematopoietic disorders. The invention provides a method to treat a deficiency of one or more types of blood cells in a mammal, which includes administering an effective amount of TISF or of a compound that stimulates CD4+ cells like TISF does. In one embodiment, TISF that originates from a mammalian species is administered to a mammalian subject diagnosed as having a deficiency in one or more types of blood cells.

Abstract: The present invention provides antigen complexes comprising 15 or more, in some instances 15 to 100 or more, different antigens and/or compositions comprising the antigen complexes where the composition comprises 15 or more, in some instances 15 to 100 or more, different antigens. The invention also provides to methods of modulating immune responses through administration of the complexes to an individual and to methods of identifying immunodominant epitopes with use of the antigen complexes.

Abstract: Vaccines capable of eliciting an immune antitumor response for prostate tumors are disclosed. The active ingredient in such vaccines is selected from the group consisting of at least one antigen over-represented in the prostate gland or an immunologically effective portion thereof; an expression system capable of generating in situ said antigen or portion; a naked DNA encoding such antigen and portion; and an anti-idiotypic antibody or fragment thereof which mimics said antigen or portion.
