Background
Almost half of the world's pregnancy is unexpected or untimely. Current long-lasting reversible contraceptive techniques focus on hormonal approaches or surgery. Despite their overall effectiveness, contraceptive techniques available to both females and males suffer from a myriad of disadvantages. As an example, some women are unable to tolerate hormonal contraception. In addition, hormonal approaches often require strict discipline or discomfort of the recipient. For example, pill or patch regimens may be required to be taken or administered periodically during the time that contraceptive efficacy is desired. Implantable or intrauterine devices may cause mild to severe side effects and complications, and may still require clinical visits for reversal or re-implantation.
Thus, there is a need for an effective, durable and reversible contraceptive treatment that is more convenient to use while also reducing the burden associated with treatment for the recipient in need of contraceptive effect.

Detailed Description
Referring now to fig. 1, some embodiments of the present disclosure relate to a vaccine for providing a contraceptive treatment to an individual, user, recipient, or the like. In some embodiments, the contraceptive vaccine provides contraceptive benefits to the user that are substantially equivalent in effectiveness to traditional hormonal contraception, implant contraception, physical contraception, and the like. In some embodiments, the contraceptive vaccine enhances the immune response of the user to structures present on the sperm cells. In some embodiments, the contraceptive vaccine enhances the immune response of the user to the structure of the protein or combination of proteins present on the sperm cells. In some embodiments, the contraceptive vaccine stimulates the production of anti-sperm antibodies in the user. In some embodiments, the contraceptive vaccine stimulates the production of anti-sperm antibodies that bind to sperm cells that inhibit the sperm cells' ability to fertilize an egg cell. In some embodiments, the contraceptive vaccine stimulates the production of anti-sperm antibodies that, upon binding to sperm cells, inhibit the motility of the sperm cells. Without wishing to be bound by theory, when administered to women, contraceptive vaccines stimulate the production of anti-sperm antibodies, e.g., in the vaginal mucosa, which bind to and prevent the hyperactive movement of sperm, rendering sperm unable to penetrate the ovum. Also without wishing to be bound by theory, when administered to men, contraceptive vaccines stimulate the production of anti-sperm antibodies, e.g., in the epididymis, which render the sperm substantially inert.
In some embodiments, a contraceptive vaccine comprises a contraceptive chimeric virus-like particle (VLP) 100. In some embodiments, VLP100 comprises two or more domains 102. In some embodiments, the VLP100 comprises an antigen carrier domain 104. In some embodiments, the antigen carrier domain 104 comprises one or more capsid proteins.

In some embodiments, the CGP amino acid residues are adjacent to the N-terminus of antigenic region 106A. In some embodiments, GPC amino acid residues are adjacent to the C-terminus of one or more antigenic regions 106A. Without intending to be limited by theory, these additional residues help stabilize the antigenic region 106A within the antigen carrier domain 104. In some embodiments, the VLP100 comprises seq.id.no. 1, seq.id.no. 2, seq.id.no. 3, seq.id.no. 4, seq.id.no. 5, seq.id.no. 6, seq.id.no. 7, or combinations thereof.
In some embodiments, the VLP100 is comprised in a composition. In some embodiments, the composition includes one or more preservatives, stabilizers, wetting agents, emulsifiers, buffers, fillers, and the like. In some embodiments, the composition is formulated for administration to a user subcutaneously, intravenously, intranasally, or a combination thereof.
Referring now to fig. 2, some embodiments of the present disclosure relate to a method 200 of making a contraceptive chimeric VLP. At 202, the gene for the antigen carrier protein is inserted into a plasmid. At 204, overlapping primers for the antigen carrier and the chimeric gene from one or more antigenic regions of the sperm cell are prepared.

In some embodiments, the VLP comprises seq.id.no. 1, seq.id.no. 2, seq.id.no. 3, seq.id.no. 4, seq.id.no. 5, seq.id.no. 6, seq.id.no. 7, or combinations thereof. In some embodiments, the VLP folds spontaneously. In some embodiments, the VLP is one or more of the VLPs 100 described above.
Referring now to fig. 3A, some embodiments of the present disclosure relate to a method 300 for providing a contraceptive treatment to a recipient. At 302, a composition is prepared comprising a contraceptive chimeric VLP comprising an antigen carrier domain and one or more antigenic regions from sperm cells within the antigen carrier domain. In some embodiments, the chimeric VLP is one or more of the VLPs 100 described above. At 304, the composition is administered to the recipient to enhance the recipient's immune response to the one or more antigenic regions. In some embodiments, the composition is administered to the recipient subcutaneously, intravenously, intranasally, or a combination thereof. Without intending to be limited by theory, contraceptive immunity is expected to last from about 1 year to about 9 years based on prior experience in immunizing women against HPV. Referring now to fig. 3B, in some embodiments, at 306, the recipient is administered a supplemental composition to reverse the effects of the aforementioned composition. In some embodiments, the supplemental composition comprises a reversal agent having a protein sequence substantially identical to the one or more antigenic regions.

In some embodiments, the supplemental composition includes one or more preservatives, stabilizers, wetting agents, emulsifiers, buffers, fillers, and the like. Without wishing to be bound by theory, immune infertility induced by the composition is reversed by sequestering the antisperm antibodies using an excess of the supplemental composition. In some embodiments, if the sperm-immunized individual wishes to regain fertility for a short period of time, a fertility window may be established by application of a reversal agent.
Examples
Design of chimeric L1.For example, a chimeric L1 VLP-forming protein was prepared that included short antigen segments from the sperm cation channel, cats er. The antigenic segment of Catsper is generated byThe extracellular loops are identified as predicted using homology modeling. The site of insertion of the L1 gene was identified by multiple sequence alignment of homologous papillomavirus L1 sequences. Three candidate insertion sites were identified as sites for natural insertions/deletions. A sequence encompassing cgp. The DNA sequence was designed using DNAworks.
Cloning of chimeric L1.HPV type 11L 1 gene was synthesized using assembly PCR method. This gene was inserted into the NdeI and EcoRI cloning sites of the pET28a + vector. Plasmids were grown and purified from cell culture using the E.coli strain DH5 α. Chimeric constructs were prepared by amplifying plasmids using overlapping oligonucleotides containing the sequence of the desired antigenic region (inverse PCR). The amplicon was transformed into DH5 α cells for plasmid amplification and transferred into BL21(DE3) pLysS cells for protein expression.
Isolation of Inclusion Bodies (IB).The recombinant proteins HPV type 11L 1 protein (L1), L1 with Catsper loop S3-S4 (P1), and L1 with Catsper-epsilon loop 331-348 (C5) were expressed in E.coli. Recombinant proteins (L1, P1 and C5) were purified from Inclusion Bodies (IB) isolated from E.coli Bl21(DE3) transformed with the plasmid constructs pET28a-L1-P1 and pET28 a-L1-C5. After induction of recombinant protein synthesis, cells were harvested from 500ml of transformed E.coli cell culture. Approximately 1g weight of wet cell biomass was resuspended in 25ml of buffer (50mM Tris, 50mM NaCl, pH9.5) by gentle stirring. The suspension was sonicated (run for 10 seconds then stop for 10 seconds, 15 cycles in ice) and then centrifuged at 12,000g for 20 minutes at 4 ℃ to precipitate the IB. The harvested IB's were washed twice with wash buffer 50mM Tris (pH 9.5).
Dissolution and refolding.The relatively purified IB was dissolved in 5ml of solubilization buffer (50mM Tris (pH9.5), 50mM NaCl, 8M urea) and gently stirred at room temperature for 2 hours. The resulting suspension was centrifuged at 11000rpm for 36 minutes at 25 ℃ to collect total soluble protein. Solubilized IBs were refolded using a pulsed dilution method in 10 volumes of ice-cold refolding buffer (50mM Tris, 50mM NaCl, 5% beta-mercaptoethanol and 100mM L-arginine (pH9.5)) at a rate of about 0.1 ml/min. Refolded proteins at 11000 ℃Centrifuge at rpm for 45 minutes.
Dialysis and in vitro assembly of virus-like particles (VLPs).The refolded protein was filtered through a 0.2 μm filter (VWR) and dialyzed against dialysis buffer (50mM Tris, 100mM NaCl, pH9.5) at 4 ℃ using a 12-14kDa cut-off dialysis membrane (Spectra/Por, VWR). After 3 dialysis buffer changes at 3 hour intervals, the NaCl concentration was gradually increased to 500 mM. Final dialysis was performed for 2 hours against high salt buffer (50mM Tris, 500mM NaCl, pH 9.5).
Methods and systems according to some embodiments of the present disclosure relate to contraceptive vaccines for providing a sustained but reversible contraceptive effect. The structure of the contraceptive vaccine stimulates an immune response to antigens present only in the sperm cells, producing anti-sperm antibodies that effectively bind sperm and render these cells incapable of insemination. The contraceptive vaccine is simple to produce and use. The need for hormonal treatment and/or surgery is avoided because no action other than vaccination is required to achieve the benefits of the compositions of the present disclosure. Finally, contraceptive immunity is easily and immediately reversible, and over time immunity automatically reverts to the contraceptive state.
Although the present invention has been described and illustrated with reference to exemplary embodiments thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions and additions may be made therein and thereto, without parting from the spirit and scope of the present invention.
