摘要:
The present invention provides variant LcrE sequences and/or combinations of variant LcrE sequences across the Chlamydia trachomatis serovars. Such changes in LcrE genotypes across the Chlamydia trachomatis serovars are likely to correspond with changes in LcrE phenotypes, in particular, with changes in immunogenicity. The present invention also provides peptides surrounding or associated with the amino acid substitutions, in particular, peptides surrounding or associated with high frequency mutated amino acid positions or hypervariable regions, which are likely to be B and/or T cell epitopic regions capable of eliciting Chlamydia specific cell mediated immune responses. The variant LcrE sequences and/or combinations of the variant LcrE sequences and/or epitope regions associated with the variant LcrE sequences are useful as immunogens and/or in the preparation of immunogenic compositions for preventing and/or treating and/or, diagnosing Chlamydia infections.
摘要:
An immunogenic Chlamydia HtrA protein, which has one or more mutations relative to wild-type Chlamydia HtrA that result in a reduced or eliminated protease activity relative to the protease activity of wild-type Chlamydia HtrA. In some embodiments the serine protease activity is reduced or eliminated.

The invention includes a GAS antigen, GAS 40, which is particularly suitable for use either alone or in combinations with additional GAS antigens, such as GAS 117, GAS 130, GAS 277, GAS 236, GAS 40, GAS 389, GAS 504, GAS 509, GAS 366, GAS 159, GAS 217, GAS 309, GAS 372, GAS 039, GAS 042, GAS 058, GAS 290, GAS 511, GAS 533, GAS 527, GAS 294, GAS 253, GAS 529, GAS 045, GAS 095, GAS 193, GAS 137, GAS 084, GAS 384, GAS 202, and GAS 057.
摘要:
The invention relates to immunogenic polypeptides derived from epitopes in a Streptococcus agalactiae (“GBS”) protein GBS 80 and their use as prophylactic, diagnostic and therapeutic compositions. The invention also provides nucleic acids encoding the immunogenic polypeptides. Also provided are vectors useful for making such immunogenic polypeptides and host cells transformed with such vectors. In particular, the invention relates to a group immunogenic polypeptides derived from GBS 80. The compositions may include one or more of the immunogenic polypeptides either alone or with other antigenic components. For example, the immunogenic polypeptides may be combined with other GBS antigens to provide therapeutic compositions with broader range. In addition, the immunogenic polypeptides may also include flanking portions of the GBS 80 protein.

The present invention relates to the use of CD81 protein and polynucleic acid in the therapy and diagnosis of hepatitis C and pharmaceutical compositions, animal models and diagnostic kits for such purposes.
摘要:
The invention provides proteins from group B streptococcus (Streptococcus agalactiae) and group A streptococcus (Streptococcus pyogenes), including amino acid sequences and the corresponding nucleotide sequences. Data are given to show that the proteins are useful antigens for vaccines, immunogenic compositions, and/or diagnostics. The proteins are also targets for antibiotics.

摘要:
A process is described for the production of D-&agr;-amino acids by the stereospecific conversion of racemic mixtures of 5-substituted hydantoins using a microorganism transformed with a plasmid which expresses an enzymatic system which converts the hydantoins into the corresponding D-&agr;-amino acids without the requirement for inducers. Also described is a plasmid containing genes encoding the enzymatic system, and a microorganism transformed with the plasmid.
摘要:
The structural gene encoding isoamylase from Pseudomonas SMP 1 is obtained. Also described are vectors comprising the isoamylase gene and host microorganisms transformed by these vectors. The transformed host microorganisms are capable of expressing and/or secreting mature isoamylase having biological activity.
摘要:
A hybrid plasmid which is capable of inducing the expression and the secretion of human growth hormone (hGH) in its natural form and a method for the preparation of hGH which comprises the culture in a suitable environment of Bacillus subtilis cells transformed by the hybrid plasmid, are described.The hGH thus obtained has the correct amino acid sequence and is particularly useful for treatment of man.
