Disclosed is an invention related to the preparation and use of vaccines against pathogenic organisms, such as herpes virus. The vaccines hereof are based upon the use of truncated, membrane-free derivatives of a membrane-bound polypeptide from the pathogen. These polypeptides when incorporated into a vaccine composition afford protection against pathogenic challenge after administration.

Immunogenic composition based on a truncated derivative of a membrane bound protein and process for making it

This invention concerns new PSTPIP polypeptides which are bound by and dephosphorylated by the PEST family of protein tyrosine phosphatases. The invention specifically concerns native murine PSTPIP polypeptides and their homologues in other mammals, and their functional derivatives. The invention further relates to nucleic acids encoding these proteins, vectors containing and capable of expressing such nucleic acid, and recombinant host cells transformed with such nucleic acid. Methods for inducing the plymerization of actin monomers in eukaryotic cells and assays for identifying antagonists and agonists of the PSTPIP polypeptides of the present invention are also provided.

Tyrosine phosphorylated cleavage furrow-associated proteins (PSTPIPs)

Diagnostic product and vaccine for Acquired Immuno-deficiency Syndrome (AIDS) and methods for making and using same, wherein viral polypeptide sequences from an AIDS associated retrovirus are expressed directly or as a fusion polypeptide in a prokaryotic or mammalian cell expression host to produce a diagnostic product which specifically binds complementary antibody produced by individuals afflicted with AIDS or a vaccine against AIDS which confers resistance to infection by AIDS associated retrovirus. The reverse transcriptase of an AIDS associated retrovirus is used separately or in a whole cell assay to identify compounds which selectively inhibit retroviral reverse transcriptase.

Molecularly cloned acquired immunodeficiency syndrome polypeptides and their methods of use

Novel polypeptides are provided, together with methods for making and using them, and nucleic acids encoding them. These polypeptides are useful as cell surface adhesion molecules and ligands, and are useful in therapeutic or diagnostic compositions and methods.

Hybrid immunoglobulins

This invention concerns new non-receptor protein tyrosine phosphatases of the hematopoietic stem cells (PTP HSC). The invention specifically concerns native murine and human PTP HSCs, their analogs in other mammals, and their functional derivatives. The invention further relates to nucleic acid encoding these proteins, vectors containing and capable of expressing such nucleic acid, and recombinant host cells transformed with such nucleic acid. Assays for identifying agonists and antagonists of the native PTP HSCs, methods for expansion of undifferentiated stem cells, and methods for the induction of stem cell differentiation are also within the scope of the invention.

Protein tyrosine phosphatases

The invention concerns novel members of the endocytic type C lectin family and methods and means for producing them. The native polypeptides of the invention are characterized by containing a signal sequence, a cysteine rich domain, a fibronectin type II domain, 8 type C lectin domains, a transmembrane domain and a cytoplasmic domain. Nucleotide sequences encoding such polypeptides, vectors containing the nucleotide sequences, recombinant host cells transformed with the vectors, and methods for the recombinant production for the novel type C lectins are also within the scope of the invention.

Disclosed is an invention related to the preparation and use of vaccines against pathogenic organisms, such as herpes virus. The vaccines hereof are based upon the use of glycoproteins of the organism, that have been prepared via recombinant means, and preferably C-truncated versions thereof. These glycoproteins when incorporated into a vaccine composition afford protection against pathogenic challenge after administration.
