Reagents and methods are provided that allow for an improved expression of a recombinant protein. More specifically, the introduction of recombinant DNA elements into a host cell allows for the increased expression of a recombinant protein, an improvement of the correct folding of said protein and an increase in cell viability and proliferation of the host cell, These recombinant DNA elements can be introduced into host cells, for example, via a recombinant baculovirus, which has incorporated said elements. The recombinant DNA elements include nucleic acids encoding transcriptional regulators, such as IE-0 and IE-1, transcriptional enhancer elements, such as the homologous region (hr) and promoters.

The present invention may be included in the field of biotechnology and it covers the improved production of recombinant proteins in insect cells or insect larvae as biofactories by a novel expression cassette. This expression cassette comprises nucleic acid sequences such as promoters, homologous regions (hr) as enhancers, and sequences encoding transcriptional regulators, for example, the baculovirus Ac-ie-01 cDNA, or any combination thereof, which are able to increase the quality and production efficiency of the recombinant proteins. Moreover, the present invention is also directed to the vectors themselves comprising the above mentioned nucleic acid sequences of the invention, cells or insects infected, transformed or transfected with those sequences or vectors, and methods for producing the recombinant proteins by using the aforesaid sequences, vectors, cells or insects.

Reagents and methods are provided that allow for an improved expression of a recombinant protein in an insect, More specifically, the introduction of recombinant DNA elements into an insect larva allows for the increased expression of a recombinant protein, an improvement of the correct folding of said protein and an increase in the survival rate after infection of the insect These recombinant DNA elements can be introduced, for example, into insect larvae via a recombinant baculovirus, which has incorporated said elements. The recombinant DNA elements include nucleic acids encoding transcriptional regulators, such as IE-0 and IE-1, transcriptional, enhancer elements, such as the homologous region (hr) and promoters.

New antiviral peptides interfering the binding of the virus to DLC8 are provided. A high number of pathogenic agents of viral origin use the dynein based intracellular transport machinery at some point of their infective cycle. The present invention consists of a new antiviral therapy consisting in the inhibition of viral infections produced by those virus that use the dynein system by mechanisms of interference mainly by preventing the interaction between the viral protein and the cellular DLC8 protein. The present invention discloses for the first time the blocking of the function of this interaction by peptides whose sequence comprises or consists of the totality or a partial sequence of the viral protein corresponding to the binding domain with DLC8.
