摘要:
Purified Chlamydia major outer membrane protein (MOMP) has been observed to induce protection against genital and respiratory challenge in mice. MOMP contains variable domains that are highly immunogenic and elicit cross-serovar neutralizing monoclonal and polyclonal antibodies and T cell responses in animal and human models. Examples herein provide a method for vaccinating a subject against Chlamydia using a composition that is a recombinant Neisseria porin that contains at least one antigenic variable domain of Chlamydia. The variable domains are inserted into the amino acid sequence of the Neisseria porin at a position encoding a surface-exposed loop of the Neisseria porin. The vaccine further contains an adjuvant that induces a Th1 response greater than a Th2 response.

The invention is in the field of outer membrane vesicles (OMV) and their uses. More particularly the present invention provides OMV obtained from a bacterium being an ompA mutant and/or a mutant in one or more components of the TolPal complex and presenting a heterologous antigen on its surface. The heterologous antigen is selected from the group consisting of Chlamydia trachomatis CT823, CT681, CT372, CT443, CT043, CT733, CT279, CT601 and CT153 for the treatment, prevention or diagnosis of Chlamydia infection.
摘要:
The present invention relates to a method and kit for detecting and diagnosing Chlamydia suis infections in a subject using peptides comprising the amino acid sequence of GTKDASID and/or SQQSSIAS as antigenic determinants.
摘要:
A recombinantly expressed nucleotide triphosphate transporter efficiently imports the triphosphates of unnatural nucleotides into cells, and the endogenous cellular machinery incorporates those nucleotides into cellular nucleic acids. UBPs can therefore form within the cell's nucleic acids. Moreover, neither the presence of the unnatural triphosphates nor the replication of the UBP represents a significant growth burden. The UBP is not efficiently excised by nucleic acid repair pathways, and therefore can be retained as long as the unnatural triphosphates are available in the growth medium. Thus, the resulting cell is the first organism to stably propagate an expanded genetic alphabet.

The present invention relates to means and methods to protect against disease caused by bacteria belonging to the genus Chlamydia. In particular, the present invention relates to isolated B- and T-cell epitopes derived from the major outer membrane protein of Chlamydia psittaci which can be used against an infection with a species of the genus Chlamydia. More in particular, the invention provides a vaccine which can be used against chlamydiosis caused by Chlamydia psittaci in birds and man. In addition, the invention relates to a diagnostic method to diagnose the latter infections.
摘要:
Methods and compositions are provided herein for immunizing a subject by administering to the subject an effective amount of an immunogenic peptide or an immunogenic fragment or variant thereof incorporated within a vault-like particle carrier. The methods and compositions advantageously exhibit enhanced ability to induce cell-mediated immunity and/or antibody-based immunity.
摘要:
The present invention is related to antigen from Chlamydia trachomatis which are recognized by specific antibodies from individuals infected with Chlamydia or which can induce T cells from the same individuals to secrete gamma-interferon. The T cell reactive antigens are present in a whole-cell lysate and have apparent molecular weights of 5-12, 16-20, 25-35 and 58-74 kDa as determined by SDS-PAGE. The antigens of the invention are believed to be useful in vaccines but also as diagnostic compositions.
摘要:
The present invention relates to compositions comprising proteins or polynucleotides of Chlamydia sp., in particular combinations of proteins or polynucleotides encoding them, and methods for the use of the proteins or polynucleotides in the treatment, prevention and diagnosis of Chlamydia infection.
摘要:
The present invention regards polypeptides capable of eliciting an immunological response that is protective against Chlamydia trachomatis. The polypeptide comprises a first amino acid sequence which has at least 90% homology with the amino acid sequence according to SEQ ID NO: 1 and a second amino acid sequence which has at least 90% homology with the amino acid sequence according to SEQ ID NO: 2. Furthermore, production of these polypeptides and pharmaceutical compositions comprising them are also provided.

摘要:
In accordance with the present invention, there are provided novel Death Domain (DD), Death Effector Domain (DED) and NB-ARC domain proteins. The invention also provides nucleic acid molecules encoding DD, DED and NB-ARC domain proteins, vectors containing these nucleic acid molecules and host cells containing the vectors. The invention also provides antibodies that can specifically bind to invention DDs, DEDs or NB-ARC domains. Such DDs, DEDs and NB-ARC domains and/or anti-DD, anti-DED or anti-NB-ARC domain antibodies are useful for discovery of drugs that suppress infection, autoimmunity, inflammation, allergy, allograft rejection, sepsis, and other diseases.
