Definitions
- the invention relates to a method for obtaining virus-like particles based on polyomaviruses. Areas of application are medicine, u. a. Gene therapy, vaccine development and diagnostics, as well as veterinary medicine.
- virus-like particles Compared to such virus vectors, virus-like particles (VLPs) have the advantage that they are not infectious and have no tumorigenic potential.
- VLPs can be generated by expression of viral capsid and envelope proteins in various heterologous expression systems (overview in Ulrich et al., Adv. Virus Res. 50, 1997).
- Virus-like particles based on the main capsid protein VP1 ('virus protein 1') from polyomaviruses received special attention for gene transfer. So far, VP1 of various polyomaviruses have been expressed in insect cells.
- the recombinant VPI of non-human and human polyomaviruses spontaneously assembled into VLPs in the insect cells (Montross et al., 1991, J. Virol.
- capsomeres have been successful to express, which can be re-associated to VLPs in vitro (Salunke et al., 1986, Cell 46, 895-904).
- the aim of the invention is to develop a method for obtaining virus-like particles for gene therapy, diagnostics and vaccine development. This process is intended to enable the highly efficient production of non-infectious, endotoxin-free virus-like particles that are suitable for human applications.
- the essential component of the method according to the invention is a yeast expression system which allows the high expression of capsid-like particles of polyomaviruses. These particles can be isolated in large quantities from yeast cells and purified by simple centrifugation steps.
- the method involves PCR amplification and cloning of a polyomavirus VPI coding sequence.
- This DNA sequence is built into a yeast expression vector with a yeast-specific expression unit (promoter and transcription stop signal).
- the VP1 is expressed in yeast cells, preferably in the Saccharomyces cerevisiae strain AH 22 (leu2 his4).
- the virus-like particles are sedimented by ultracentrifugation (sucrose cushion).
- the particles are cleaned by subsequent ultracentrifugation in a cesium chloride gradient.
- the subsequent analysis of the particles is carried out by electron microscopy.
- the invention makes available a novel expression system for virus-like particles of polyomaviruses, which has significant advantages over the previously available systems in E. coli or insect cells.
- yeast expression systems allow the biotechnological production of antigens.
- yeasts have no toxins that would cause undesirable side effects in human or veterinary applications.
- yeast systems are already approved for human vaccine production: the recombinant HBV vaccine is based on yeast-expressed HBsAg.
- yeast cells synthesize the polyomavirus VP1 in large quantities.
- the VPl particles can be isolated and purified in large quantities using simple methods. You are u. a. can be used for the detection of infections with human polyomaviruses, as a vehicle for gene transfer, for a vaccine development against human polyomaviruses or against other viruses (eg by presenting foreign epitopes on HaPV-VPl capsids).
- HaPV virions are isolated from epitheliomas of HaPV-infected Z3 hamsters and purified by sucrose / cesium chloride gradient centrifugation.
- the virions are denatured by adding sample buffer, separated in the SDS polyacrylic gel and then transferred to a PVDF membrane.
- the VP1 protein band is cut out and sequenced using the Edman degradation at the N-terminus. According to the N-terminal protein sequence, molecular weight and predicted open reading frame the VPl-coding sequence is amplified by means of PCR.
- Viral DNA is used as a template and is obtained from HaPV virions by phenol-chloroform extraction and subsequent ethanol precipitation.
- oligonucleotide primers are used for the PCR, which contain the initiation codon (ATG) or termination codon (TAA; complementary sequence) and cleavage sites for the restriction endonuclease Xbal at the 5 'and 3' ends:
- VPl-Xba-N2 5'-A CGT CTA GAT ATG GCC CCA AAA AGA AAA AGC GGC-3 'VPl-Xba-C: 5'-TCT AGA_TTA GTT TGC TGG TTT TGC AGG GGG-3'
- pFR36 E. coli vector
- yeast-specific promoter (GALIO-PYKI hybrid promoter, which consists of a -138 to -511 nucleotide fragment of GAL10 with GAL1-10 UAS sequences and the -4 to -271 sequence of PYK1),
- the VPl-coding segment (with its own translation initiation and termination signal) is cut out of pFR36-VPl with Xbal and ligated into the yeast expression vector pFX7 linearized with Xbal. Recombinant plasmids are selected after transformation in E. coli K12 (XL-1 Blue) and characterized by restriction mapping. 3. Expression of the main capsid protein from polyomavirus in yeast
- the HaPV-VPl expression plasmid is transformed in yeast cells, preferably in Saccharomyces cerevisiae, strain AH22 (leu2 his4).
- the transformed yeast cells are grown in YEPD medium (1% yeast extract, 2% peptone, 2% glucose) with 5 mM formaldehyde. After culturing for 30 minutes at 30 ° C., the cells are harvested, re-inoculated with formaldehyde in YEPG medium (1% yeast extract, 2% peptone, 3% galactose) and cultivated for a further 24 hours. An aliquot is taken for the expression control and denatured with sample buffer. After separation in the SDS polyacrylamide gel, the recombinant HaPV-VP1 is detected in a Western blot using a VP1-specific rabbit serum (Fig. 2).
- the yeast cells grown as described under 3 are resuspended after sedimentation in 1 ml of lysis buffer (20 mM sodium phosphate, pH 7.2; 100 mM NaCl; 2 M PMSF) and after adding 1 g of glass beads (0.5 mm) Vortexing for 4 minutes at 4 ° C.
- the resulting lysates are diluted with twice the volume of lysis buffer and centrifuged at 5000 g for 10 minutes.
- 8.5 ml of a 45% sucrose solution (w / v; in lysis buffer) are overlaid with 1.5 ml of the supernatant.
- the particles are sedated by centrifugation at 100,000 g for 4 hours in a Beckman Ti70.1 rotor.
- the sediment is resuspended in lysis buffer (20 mM sodium phosphate, pH 7.2; 100 mM NaCl and 2 mM PMSF).
- a previously layered cesium chloride gradient (1.38, 1.35, 1.32, 1.29, 1.26 and 1.23 g / ml in 50 mM Tris-HCl, pH 7.5) is loaded with this suspension and 15 Centrifuged for hours at 100,000 g in the Beckman Ti70.1 rotor. Fractions are collected and analyzed by SDS-polyacylamide gel electrophoresis and Western blot. The formation of HaPV-VPl particles is demonstrated by negative staining with 1% uranyl acetate and electron microscopic analysis (Fig. 3). Fractions containing particles are dialyzed against lysis buffer.
- HaPV-VPl serum (b) or a serum of a HaPV-infected
- Lanes B and C HaPV-VPl expressing yeast cells
- Lane A yeast cells without VPI expression plasmid
- the VPl protein band is marked by arrows.
