The invention provides a viral self-inactivating (SIN) vector on the basis of the avian sarcoma leukosis virus (ASLV) as well as a split-packaging system comprising in addition to the SIN vector a first helper plasmid serving for the expression of the viral fusion protein gag-pol and a second helper plasmid serving for the expression of the retroviral envelope protein (env). The first and second helper plasmid, for example contained in a packaging cell line or transiently transfected, serve for the generation of non-replicating (RCR-incompetent) viral particles containing RNA having a SIN LTR according to the invention at the 3′ terminus, wherein the RNA can have a therapeutically effective section which e.g. is denoted a transgene. This 3′ SIN LTR contains an extensive deletion of the U3 region which in the course of the reverse transcription is copied into the 5′ LTR. In addition, in the SIN vector all coding regions of ASLV as well as the retroviral splice donor site are removed.

Said invention provides recomposed foot-and -mouth disease virus VP1 fusion protein vaccine, which fuses peptide section of foot-and -mouth disease virus VP1, 2-polyglycine and 6-polyhestidine coded gene and recomposes fusion protein in bacillus coli. Said invention also provides amino acid sequence of recomposed foot-and -mouth disease virus VP1 fusion protein and nucleotide sequence, and effect for preventing foot-and -mouth disease virus infection.

Compositions, methods, and kits are provided for treating CCR8 mediated diseases with applicability to atopic dermatitis and potential applicability to asthma, prurigo nodularis, nummular dermatitis, neurodermatitis, and lichen simplex chronicus and some lymphomas, multiple sclerosis, acquired immunodeficiency disease, peritoneal adhesions, Kaposi's sarcoma and atherogenesis—the expression of all of which, at least in part, is mediated by cells expressing the chemokine receptor CCR8. The compositions include proteins and fusion proteins from Molluscum contagiosum Virus (MCV) or variants, analogs and derivatives thereof which exhibit inhibitory activity. Examples of such MCV proteins are MC148 fusion protein (MC148fp) identified as MC148P-TAT-6×His (“6×His” disclosed as SEQ ID NO: 11), and its variants, fragments, analogs and derivatives which possess inhibitory activity. The variants, fragments, analogs and derivatives of MC148p and of MC148fp may be less than 100% homologous to MCV proteins as long as they are sufficiently homologous that inhibitory activity is preserved.
