The present invention relates to peptide fragments which have one or more shared and/or similar amino acid sequences to amino acid sequences of specific portions of the 14 kDa protein of S. mansoni (SM14) or related FABPs (Fatty Acid Binding Proteins), the peptide fragments functioning as continuous or discontinuous epitopic regions of the molecule or mimicking its biological activity. More particularly, the present invention relates to a method for constructing active peptide fragments, peptide fragments, immunogenic compositions and diagnostic kits using peptide fragments.

The present invention includes a composition including as one component a slurry matrix that is a liquid at room temperature and a gel at physiological pH, physiological salt concentrations and/or physiological temperatures and as a second component one or more antigens. Also include are methods of inducing an immune response in a subject and vaccinating a subject by administering such compositions.

The present invention relates to methods for stable transfection of Babesia parasites, and for vaccines conferring immunity against parasitic arthropods.

The present invention provides a dendritic cell modulatory protein which modulates, and preferably inhibits, the differentiation and/or maturation of mammalian dendritic cells. The invention also provides proteins comprising conserved motifs found in such proteins as well as pharmaceutical compositions comprising the dendritic cell modulatory protein and homologs and active fragments thereof, antibodies thereto and methods of treatment which utilize such proteins, homologs, fragments and antibodies.

The present invention relates to compositions comprising peptides for preventing or treating allergy to house dust mites, and in particular to optimal combinations of peptides for preventing or treating said allergy.

The present invention relates to peptide fragments which have one or more shared and/or similar amino acid sequences to amino acid sequences of specific portions of the 14 kDa protein of S. mansoni (SM14) or related FABPs (Fatty Acid Binding Proteins), the peptide fragments functioning as continuous or discontinuous epitopic regions of the molecule or mimicking its biological activity. More particularly, the present invention relates to a method for constructing active peptide fragments, peptide fragments, immunogenic compositions and diagnostic kits using peptide fragments.

Disclosed is a use of trimanganese tetraoxide particles in preparation of a vaccine adjuvant. The adjuvant is a particle adjuvant, the particle adjuvant is trimanganese tetraoxide particles externally wrapped with or without an excipient, and the particle size of the particle adjuvant is 5 nm to 3000 nm. The trimanganese tetraoxide particle adjuvant provided in the present invention can be effectively combined with a single-stranded nucleotide adjuvant and can effectively carry an immune antigen, and a more excellent immunotherapy effects can be achieved when a fewer antigen dose and a relatively low injection amount are used; immune cells are efficiently activated, and body fluid balance and cellular immunity are achieved.

The present invention includes compositions and methods for the use of an encapsulation additive having between about 0.1 to about 30 percent isolated and purified vitelline protein B to provide for mixed and extended release formulations.

A method for reducing or alleviating inflammation in a subject includes administering to the subject a therapeutically effective amount of: (a) Ac-TMP-1 or a biologically active fragment or variant of Ac-TMP-1; (b) Ac-TMP-2 or a biologically active fragment or variant of Ac-TMP-2; or (c) a combination of (a) and (b), to thereby reduce or alleviate inflammation in the subject. A method for preventing or treating asthma or inflammatory bowel disease in a subject includes administering to the subject a therapeutically effective amount of: (a) Ac-TMP-1 or a biologically active fragment or variant of Ac-TMP-1; (b) Ac-TMP-2 or a biologically active fragment or variant of Ac-TMP-2; or (c) a combination of (a) and (b), to thereby prevent or treat asthma or inflammatory bowel disease in the subject. The subject may be a mammal, inclusive of humans.
