Replicons have been used for decades as a platform for The two properties that make it a successful candidate are 1) high and long-lasting protein expression and 2) robust cell proliferation. Platform autoadjuvants that boost cytotoxic, humoral, and mucosal immunity These properties make replicons excellent vaccine platforms. However, in other areas, platforms are becoming increasingly popular, particularly for the in vivo expression of biologics. This may interfere with the replicon's performance as a system.

[0004] The use of biological agents in medicine is increasing. However, recombinantly produced These proteins are often recognized as foreign and trigger immune responses and anti-drug antibodies (AD). A) and consequently reduce the therapeutic efficacy of the protein. A) The factors responsible for the occurrence of a response are diverse, but the biological agent or biologic is delivered The resulting inflammatory environment may promote and / or enhance the ADA response. Therefore, for the delivery of replicon-derived biologics that are naturally self-adjuvanting and proinflammatory. This may enhance the ADA response and reduce the clinical efficacy of the encoded biologic. downregulating the immune response to the heterologous protein expressed from the replicon. This ability to inhibit ADA production reduces the risk of developing biologics in vivo. This will likely increase the usefulness of replicons in the current situation.

[0005] Therefore, it is possible to produce a human or animal model with reduced or eliminated risk of eliciting an unwanted immune response.

USA 87, 2264-2268). Using the algorithm, BLAST (Basic Local Alignment This can be determined by BLAST (Block Search Tool) analysis. The more commonly used approach is to first compare the query sequence with the data, with or without gaps. The similarity segments between the database sequences are considered, and then statistics of all the matches identified are compiled. Finally, we evaluate the significance of those matches by a preselected significance threshold. In a similarity search of a sequence database, For a discussion of the fundamental issues involved, see Altschul (1994), Nature Genetics 6, 119-129.

USA 89, 10915-10919), and lengths greater than 85 (nucleobases). Recommended for query sequences (nucleotides or amino acids).

[0045] In the case of blastn, which is designed to compare nucleotide sequences, the scoring matrix The formula is a function of M (i.e., the reward score for a pair of matched residues) and N (i.e., the number of mismatches). The default values ​​for M and N are set by the ratio of the penalty score for the residue to the penalty score for the You can set the four blastn parameters as follows: Allowed: Q=10 (gap creation penalty); R=10 (gap extension penalty) wink=1 (generates word hits at every wink along the query) and gapw=16 (sets the window width in which gapped alignments occur) The equivalent Blastp parameter settings for comparing amino acid sequences are Q=9, R=2, wink=1, and gapw=32. BESTFIT® comparisons between sequences available in version 10.0 are based on DNA parameters. GAP=50 (gap creation penalty) and LEN=3 (gap extension penalty) penalty) can be used, and the equivalent settings for protein comparison are GAP=8 and and LEN=2.

[0127] [Example 1] Immunogenicity of VEEV-based replicons A VEEV-based alphavirus replicon encoding a mutant nsP3 was used as a vector for the V The nucleotide sequence encoding amino acids 335 to 518 of EEV nsP3 was used to identify the chikungunya virus. The nucleotide sequence encoding amino acids 335 to 517 of CHIKV nsP3 In place of the VEEV / CHIKV nsP3 chimera (SEQ ID NO: 30), This replacement allowed the VEEV-based replicon to be constructed. The first motif of the repeat sequence was deleted from the (in which the motif is replaced with the FGDF / FGDF (SEQ ID NO: 20) repeat from the CHIKV genome In a parallel experiment, amino acid 335 of VEEV nsP3 (HVD region) was replaced with ~538 of the amino acids (HVD region) of Sindbis virus (SINV) nsP3 The amino acids 335 to 538 of the VEEV / SINV nsP3 chimera (SEQ ID NO: A replicon encoding the nucleotide sequence of ... The repeat sequence was deleted from VEEV and replaced with FGSF from SINV by substitution. / FGSF (SEQ ID NO: 21) repeat sequence was replaced with WT, VEEV / CHIKV, or Contains VEEV / SINV chimeric nsP3 and is derived from subgenomic RNA (SGIα-rFF). Replicons expressing the red firefly luciferase (rFF) reporter from After electroporation, a portion of the cells was transferred to 6 wells of BHK-21 cells. Plated in one well of a 100-well plate and one well of a 96-well plate and incubated for 20 hours. Electroporated cells were stained for the presence of dsRNA and analyzed by flow cytometry. The frequency of dsRNA-positive cells was determined as a measure of replicon amplification. Replicons containing mutant nsP3 expressed the same level of nucleotides as replicons containing WT nsP3. The luciferase activity was analyzed and the cells were found to replicate up to 100 μg / ml (Figure 2B). However, no difference was observed between the WT-containing replicon and the indicated mutant forms of nsP3. (Figure 2C).

[0128] [Example 2] Expression of heterologous proteins from replicons In this example, a replicon encoding the mutant nsP3 shown in FIG. 2A (see Example 1) We investigated the in vivo expression of recombinant firefly luciferase (rFF) from 1) 1 or 10 micrograms of replicon RNA in saline was transfected into BALB / c mice.

The replicon expressing the mutant form was compared with the replicon containing the wild-type nsP3 from VEEV. showed similar levels of luciferase activity in vivo compared with control. be.

[0129] [Example 3] immunogenicity In this example, the immunogenicity and phenotype of a replicon carrying wild-type (WT) VEEV nsP3 were investigated. In comparison, a VEEV-based recombinant gene encoding a VEEV / CHIKV chimeric form of nsP3 was The immunogenicity of the replicons (from Example 1) was investigated. Each replicon contained a heterologous protein The hemagglutinin (HA) from the H5N1 strain of influenza was encoded and expressed as a vector. On day 0, 2.0 μg or 0.2 μg of RNA in saline was injected into the thigh of a BALB / c mouse. The mice were delivered intramuscularly to the quadriceps muscle and boosted on day 28 with the same replicon RNA and dose. Two weeks after the injection (day 42 after priming), spleens and serum were collected. Serum was analyzed by ELISA. The data show that VEEV / CHI In the replicon encoding the KV nsP3 chimera, the replicon with wild-type nsP3 The HA-specific IgG titer was significantly reduced compared to the control group.

[0130] In contrast, analysis of short-lived effector and memory precursor effector CD8+ T cells showed that there was no difference in the frequency of HA-specific cells among the different replicons tested. Figure 5A and 5B show that the wild-type, VEEV / SINV nsP3, and HA-specific short-lived effectors among the individual RNA replicons of VEEV / CHIKV nsP3 The frequency of memory effector CD8+ T cells is similar in Figure 5B. Similar results are shown for CD8+ T cells.
