Stable expression of recombinant protein therapeutics in CHO cells often relies on random or semi-random genomic integration events which results in a widely heterogenous cell population. This leads to significant effort in clone screening during cell line development in order to identify clones with high expression, growth and product quality. 

In this publication, we focus on:

• the development of two targeted integration systems that express high levels of recombinant protein in CHO cells by: 
  • the installation of rationally designed piggyBac-based chromosomal landing pads
  • the use of site specific recombinases including PhiC31 and CRE 
• demonstration of the functional integration of several donor vectors encoding various therapeutic proteins including two monoclonal antibodies and one Fc-fusion molecule

Chikungunya virus, which is transmitted by mosquitoes, can cause disabling chronic arthritis. There are currently no medicines for prophylaxis of Chikungunya, or other viruses transmitted by Aedes mosquitoes, such as Dengue and Zika. Potential therapeutics have been identified, but to perform a successful chemoprophylaxis trial during a short Chikungunya outbreak requires an identified at-risk population. We examined the potential for application of a household transmission model, as used in testing prophylactic drugs against respiratory viruses, included influenza and COVID-19.

In this poster we:

• Set out the evidence for multiple Chikungunya infections occurring per household
• Describe how we are validating the secondary household infection rate
• Show how this could be used in future clinical trials to demonstrate prophylactic efficacy against chikungunya virus infection and other Aedes-mosquito-borne viruses

In this article, we discuss the role of structure-based virtual screening in drug discovery. 

The publication covers:

• an overview of structural-based virtual screening and the importance of selecting the most appropriate protocol for affinity estimation calculations
• the development of an automated calibration process implemented in a Knime workflow consisting of 4 steps:
  • preparation of a protein test set with structures and models of the target
  • preparation of a compound test set with target-related ligands and decoys
  • automatic test of 24 scoring/rescoring protocols for each target structure and model
  • graphical display of the results
•  demonstration of the application of this tool in setting up an optimal protocol for structure-based virtual screening against Retinoid X Receptor alpha
