Definitions
- Antigens purified before vaccinating properties against B. pertussis means in particular recombinant DNAs for producing them and vaccine compositions containing them
- the invention relates to polypeptides capable of forming active principles of purified pertussis vaccines. These vaccines are directed against antigens separate from the pathogen.
- the invention relates more particularly to the associations which can be formed between these vaccinating principles. These are likely to be obtained by genetic engineering techniques.
- the invention therefore also relates to the DNA sequences coding for the above-mentioned polypeptides, as well as the vectors which contain them.
- Whooping cough is a bacterial infection, caused by
- Bordetella pertussis which causes non-septic tracheobronchitis, sometimes fatal in children under six months of age, representing the most exposed, if not exclusive, age group. This infection, known for more than five centuries, prevails in all countries and is only controlled by preventive vaccination, systematically implemented in developed countries since 1945. Once the disease has entered clinical phase, no recourse specific therapy is not possible, care is then purely symptomatic and aims to prevent anoxic phenomena and secondary infectious complications which are the causes of mortality.
- Vaccination is, however, the effective way to contain outbreaks. Indirect proof of the effectiveness of vaccination is provided by recent examples from Japan and Great Britain where the lifting of this mode of prevention has been santionnee by violent epidemics with fatal cases.
- the vaccines currently used worldwide are predominantly composed of B suspensions. pertussis, simply washed by centrifugation and then killed by heating to 56oC or sometimes by adding an antiseptic.
- the main purpose of heating to 56oC is to inactivate the dermonecrotic toxin released by the lysed bacteria.
- FHA Filamentous hemagglutinin
- fimbriae protein of PM> 150,000
- thermodenatured at 56oC devoid of pathogenic effect but dominant factor in adhesion to respiratory epithelial cells.
- Another antigen is known by the names
- leukocytosis promoter factor LPF according to the designation which will be used in the remainder of this description
- Ptx pertussis toxin
- HSF histamine sensitizing factor
- IAP protein activating the p islands of the endocine pancreas
- LPS lipopolysaccharide
- the invention therefore aims to provide polypeptides capable of being obtained with a high degree of purification and reproducibility by genetic engineering techniques.
- These polypeptides are obtained by expression in a suitable host of nucleic acid sequences, which have been obtained from a sequence bank nucleotides themselves previously obtained from the genomic DNA of B. pertussis 8144 (according to the reference of the Institut Pasteur de Paris) serotype 1.3. Construction of the B. pertussis bank 30 ⁇ g of B pertussis DNA were incubated at
- the DNA was incubated in a volume of 22.5 ⁇ l with 0.25 ⁇ g of phosphorylated EcoRI linkers (New England Biolabs) in the presence of 1000 U of T4 DNA ligase (New England Biolabs) in the appropriate buffer (66 mM Tris HCl pH 7.5, 5 mM MgCl 2 , 5 mM DTT and 0.5 mM ATP). The incubation was carried out at 4 ° C for 4 hours. 1000 U of T4 DNA ligase (New England Biolabs) were added and incubation continued 16 'hours at 4oC.
- T4 DNA ligase New England Biolabs
- the mixture was subjected to two successive cycles of freezing at -80 ° C, followed by thawing.
- the volume was brought to 50 ⁇ l with water.
- the DNA was then incubated in a volume of 250 ⁇ l in the presence of 50 units of EcoRI (New England Biolabs) for 3 hours at 37oC in the buffer recommended by the supplier. After incubation for 10 minutes at 60 ° C., the DNA was extracted with phenol as above. After addition of final 2.5 M ammonium acetate, the DNA was precipitated with 2 volumes of ethanol for 16 hours at -20 "C.
- 500 ng or 1 ⁇ g of DNA digested for 5 minutes, or 500 ng or 1 ⁇ g of DNA digested for 10 minutes were ligated independently (in the ligation buffer recommended by Promega Biotec) to 250 ng of DNA from the vector ⁇ gtl 1 (Protoclone TM GT System, Promega Biotec) in a volume of 5 ⁇ l in the presence of 200 units of T4 DNA polymerase (New England Biolabs). The reaction was carried out at 4 ° C for 16 hours.
- the products obtained were packaged in capsids of the bacteriophage ⁇ .
- the packaging extracts were prepared according to the protocol described by Maniatis et al. (Molecular cloning. A laboratory manual. Cold Spring Harbor, p. 264-267, 1982).
- the packaging is carried out as follows: 1 ⁇ l of ligated DNA (50 ng of vector) are added to 7 ⁇ l of buffer A at 4oC (20 mM Tris HC1 pH 8; 3mM MgCl 2 , 0.05% ⁇ - mercaptoethanol, 1 mM EDTA), then add 1 ⁇ l of ML buffer (6 mM Tris pH 7, 4, 18 mM MgCl 2 , 30 mM spermidine, 30 mM ⁇ -mercaptoethanol, 15 mM putrescine). 6 ⁇ l of ex ⁇ d line of packaging SE thawed at 4 ° C. are added and then 10 ⁇ l of packaging extract FTL thawed at 4 ° C.
- the mixture is incubated for 1 hour at 25 ° C, then diluted to 500 ⁇ l with 10 mM Tris buffer pH 7.4, 10 mM MgCl 2 , and spread on indicator bacteria.
- the FTL and SE extracts are extracts of the heat-induced BHB 2688 and BHB 2690 bacterial strains respectively.
- the genotype of strains is described in Maniatis et al. op.cit p. 504. In the present case, the
- phages were screened to determine the percentage of recombinant phages.
- the final yield was 300,000 recombinant phages per microgram of vector used.
- the library thus obtained containing approximately 300 times the genome of B. pertussis was screened using a mixture of human sera from patients who have contracted pertussis.
- the filters were soaked in TBS buffer (50 mM Tris 150 mM NaCl).
- the agar containing phage particles was removed, incubated for 1 hour in a 100 mM 10 mM MgSO 4 phosphate buffer at 37 ° C.
- the phages giving positive signals were repurified, the number of times necessary to obtain as many lysis ranges per dish as there were positive signals in autoradiography.
- the revelation of the lysis plaques giving potified signals has, in certain cases, been carried out by anti-rabbit-mouse or human Ig antibodies labeled with peroxidase (BIOSYS). This was especially necessary when using mouse sera.
- the lysis plaques giving positive signals with monospecific sera, directed against CYA (rabbit serum), against FHA (mouse serum) and against LPH (mouse or rabbit serum) were lysogenized in the strain RY1090 , by conventional techniques. Lysogens have been defined as having growth at 30 ° C and no growth at 42 ° C. The lysogenic clones are called respectively: RY1090 ⁇ gt11 lys CYA RY1090 ⁇ gt11 lys LPF
- the lysogens obtained in the RY1090 strain make it possible to obtain and amplify the recombinant phAges carrying the inserts corresponding to the LPF, FHA and CYA antigens. They also make it possible to obtain, according to conventional techniques, the corresponding DNA which, by suitable labeling, can serve as a specific probe.
- lysogenization is carried out in the strain RY1089 carrying; the Hf1 mutation (described by YOUNG et al.).
- Obtaining the bacterial cultures containing the desired fusion proteins is obtained by the culture of this strain at 30o C, followed by an induction of 20 minutes at 42oC, then by an induction of the 10 mM IPTG, finally by an incubation for 1 hour at 37 oC.
- the proteins can then be purified by conventional techniques.
- the vaccinating and protective potential of fusion proteins can be measured by the Kendricke test, recommended by the World Health Organization (WHO), which allows the study of the pathogenicity and immunogenicity of B. pertussis observed during the experimental infection of the mouse. It consists of estimating the lethal dose: 50% of the international reference strain (WHO) 18323 (serotypes 1, 2, 3, 4, 5, 7) for mice, immunized or not. The measurement of any immunogen with "vaccinating" potential is carried out by comparison with a vaccine of known efficacy.
- WHO World Health Organization
- the invention therefore relates more particularly to the use of CYA or of purified proteins which can be obtained from these for the constitution of principles vaccinating against pertussis.
- a preferred vaccine according to the invention contains a combination of antigens having the characteristics of FHA, LPF and CYA. One can thus benefit from the simultaneous characteristic effects of these three types of antigens.
- the invention also relates to the vaccine compositions associating the expression products of the insertion sequences contained in the three phages indicated above (or any similar product endowed with similar immunogenic properties) and recognized by anti-FHA antibodies, anti-LPF and anti-CYA.
- the invention also relates to the vaccine compositions containing effective doses of the active principles of the abovementioned vaccines, in association with any pharmaceutical vehicle suitable for the chosen mode of administration, for example by the oral, parenteral, nasal or rectal route.
- the invention relates to the insertion nucleic acid sequences themselves or to any sequence coding for similar polypeptides.
- Part of the invention are in particular the nucleic acid sequences which are capable of hybridizing with the insertion sequences contained in the vectors which have been deposited at the C.N.C.M.
