The invention discloses a recombinant vaccinia virus rVV-CCL5-SSTR2-Luc+, containing genes CCL5 and SSTR2, constructed by virtue of a homologous recombination method. By utilizing the characteristic that shuttle plasmids containing human target genes CCL5 and SSTR2 and Luciferase reporter genes have same TK side wings with a vaccinia virus WR strain, homologous recombination is carried out in a vaccinia virus susceptible cell BS-C-1 to integrate the target genes to a vaccinia virus genome, so as to construct the recombinant vaccinia virus rVV-CCL5-SSTR2-Luc+. The recombinant vaccinia virus rVV-CCL5-SSTR2-Luc+ is capable of efficiently expressing exogenous genes, meanwhile, CCL5 is matched with highly expressed CCR5 on the surface of a cell CIK, and SSTR2 has the unique advantage on directional induction of octreotide targeted tumor cells, so that the recombinant vaccinia virus is beneficial to clinical expansion and application and is used for treating various tumors.

The invention relates to the field of biotechnology, and the invention discloses a use of CCL5. The present invention utilizes the chemotactic binding ability of CCL5 and immune cell surface receptors such as DC cells to transport different antigenic proteins to the surface of DC cells, improves the efficiency of phagocytosis, processing and presentation of various antigenic proteins by DC cells, and improves the efficiency of DC cells. The effect of preventing and treating related diseases. The present invention also adds T2 sequence to the antigen so as to enhance the immune effect.

The invention discloses a method for enhancing mesenchymal stem cell chemotactic capacity and chemotactic factor CCL5 expression, and relates to mesenchymal stem cells. The method comprises the steps of separation of the mesenchymal stem cells and passage of primary culture umbilical cord mesenchymal stem cells; identification of the umbilical cord mesenchymal stem cells; stimulation of TNF-alpha and IFN-gamma to hUC-MSCs; detection of CCL5 expression through Real-Time PCR; detection of CCL5 expression through ELISA. CCL5 expression through MSCs is improved by 924 times, a large amount of natural CCL5 can be obtained, no lipofection transfection is needed, and rapidness and convenience are achieved. Due to simulation of TNF-alpha and IFN-gamma, the transfer ability of the mesenchymal stem cells is improved, it is promoted that the mesenchymal stem cells can more rapidly collect tissue injuries and inflammation portions in vivo, and the functions of tissue repairing and immune modulating are brought into play.

CC-Chemokine mutants having reduced Glycosaminoglycans (GAG)-binding properties are effective against liver fibrotic inflammatory and / or autoimmune diseases. Particularly preferred are the mutants of CCL5 / RANTES having reduced GAG-binding properties.

The present invention relates to an engineered immune cell that expresses (i) a chimeric receptor, and (ii) an exogenous CCL3, CCL4 and / or CCL5. The invention also provides application of the engineered immune cell in treatment of cancer, infection or autoimmune diseases. Compared with traditional engineered immune cells, the engineered immune cells provided by the invention have significantly improved tumor killing activity.
