The contribution of the pleiotropic hormone Prolactin (PRL) to several physiological and pathological processes is still unknown. To clarify the role of PRL in these processes during the last decade, different human PRL antagonists have been produced to either partially or fully block the wild type hormone activity. In this work, we have cloned these wild type and antagonist sequences in lentivectors (LV) to express them as recombinant self-processing polypeptides by employing a P2A sequence (hPRL-P2A-GFP).

Although intratumoral administration of IL12 is giving promising results in clinical trials, only a small percentage of patients show a complete therapeutic response. This outcome could be improved by controlling the IL12 expression window.

However, VSVg pseudotyped vectors are serum inactivated, blocking the in vivo gene delivery. Several strategies have been employed to prevent complement inactivation, including chemical and genetic envelope modifications.
