Abstract: The present disclosure is directed to compositions comprising modified interferon-?2 polypeptides having interferon-?2 activity and reduced immunogenicity. In aspects, said modified interferon-?2 polypeptides are hyperglycosylated, such as by addition of a GM-CSF-derived peptide sequence with multiple O-glycosylation sites. Furthermore, the present disclosure provides compositions comprising a nucleic acid molecule encoding said modified interferon-?2. The present disclosure also provides compositions comprising a recombinant protein expression cell line comprising said nucleic acid molecule encoding said modified interferon-?2; wherein said recombinant protein expression cell comprises a plasmid or vector containing said nucleic acid molecule. Also disclosed are pharmaceutical compositions comprising a modified interferon-?2 having interferon-?2 activity with reduced immunogenicity, as well as methods of use of said pharmaceutical formulations for treatment of medical conditions in a subject.

Abstract: A modified human erythropoietin with an increased plasma half-life, with an erythropoietic activity of less than 0.5% in relation to a native erythropoietin, which maintains the neuroprotective and neuroplastic capacity, which comprises the mutation of at least one of the binding sites the homodimeric or heterodimeric receptor by incorporating consensus sites for N-glycosylation.

Abstract: This invention relates to a combination of erythropoietin glycoisoforms, wherein such glycoisoforms may include a quantity of sialic acid ranging from 4 to 10 molecules of sialic acid per molecule of erythropoietin. The combination of glycoisoforms can be used for the treatment or prevention of sepsis, and used to prepare a pharmaceutical composition including such combination. The invention also encompasses a cell line producing a combination of erythropoietin glycoisoforms, procedures to obtain the cell line, a procedure to produce such a combination of glycoisoforms, and methods of treatment and prevention of sepsis.

Abstract: A recombinant human interferon-alpha mutein that contains at least one glycosylation site at a position of its amino acid sequence that is a part of an alpha helix-type secondary structure, a gene encoding the mutein, a method for producing the gene, a method for obtaining an eukaryotic cell producing the mutein, a method for producing the mutein, a process for purifying the mutein, a pharmaceutical composition containing the mutein, and the use of the mutein for manufacturing a medicament.

Abstract: The invention relates to a Vero cell line that can be grown in serum-free and protein-free culture and in suspension culture in the absence of carrier for its adherence, and to production of viral vaccines using said cell line. More particularly, the present invention relates to establishment of a cell line that can be grown in suspension culture without need of the cells to be adhered to any supporting material. Furthermore, the present invention provides a process to obtain said Vero cell line and a process for producing viral vaccines with said cell line. The present invention further relates to the viruses obtained using the inventive method and to the vaccines formulated with said viruses.
