  • Publication number: 20220073630
    Abstract: The present invention relates to a peptide-MHC-I-antibody fusion protein for use as a therapeutic medicament administered to a patient, wherein a cellular cytotoxic immune response towards the virus-derived peptide has been amplified in the patient. The therapeutic medicament may be used in a kit of parts and administered in combination with an amplifying medicament and optionally an inducing medicament. The inducing medicament and the amplifying medicament may be for use in a method of making a patient susceptible for a treatment with the peptide-MHC-I-antibody fusion protein. The medicament(s) may be used for the treatment of diseases, such as cancer or a viral infection.

  • Publication number: 20210024952
    Abstract: Herein is reported that for transient transfections the use of the human elongation factor 1 alpha promoter (with Intron A) provides for an enhanced productivity (in LC-HC-SM organization), the use of the bovine growth hormone polyA signal sequence provides for an enhanced productivity compared to use of the SV40 polyA signal sequence, the addition of the HUT to the bGH PolyA signal sequence results in an increased productivity in vectors containing the hCMV promoter and the vector organization LC(3?-5?)-HC-SM results in improved expression. For stable pools it is reported that pools generated with vectors containing the hEF1? promoter show an enhanced productivity in batch analysis, clones generated with vectors containing the hEF1? promoter show a reduced number of low producing clones, and clones generated with vectors containing the hEF1? promoter show a higher stability of IgG expression.
