Yes...Karolinska seems to feature a lot and notice the TCR mentioned again in relation to them...fascinating we get to know so little though till months and months after lol...
'Scancell was pleased to extend its strategic research collaboration with the Rheumatology Unit at the Karolinska Institute, Sweden. The expanded agreement will explore the potential of the Moditope® platform to develop multiple immunotherapeutic agents for a range of different cancers. Scancell's research has shown that citrullinated proteins are involved in the control of tumour growth and we believe that this expanded collaboration will help us to further develop Moditope®, not only for use in cancer vaccines, but also other cancer immunotherapy approaches including T-cell receptor (TCR) based therapeutics which is also the subject of Scancell's research collaboration with BioNTech announced in January 2018.'
So that is very positive as is Modi2 developments:
Modi-2
Whilst Modi-1 acts by stimulating the production of CD4 T cells using citrullinated tumour-associated peptide epitopes, Modi-2 exploits a new modification, stimulating the production of cytotoxic CD4 T cells using homocitrullinated tumour-associated peptide epitopes. Whereas citrullination involves the conversion of the amino acid arginine to citrulline, the process of homocitrullination involves the conversion of lysine to homocitrulline. Scancell believes this second mechanism of action has the potential to broaden the utilisation of the Moditope® platform.
Modi-2 is currently in pre-clinical development and work is underway to characterise specific homocitrullinated peptides for clinical development that have the potential to address different cancer indications to Modi-1, including tumours with a PARTICULARLY IMMUNOSUPPRESSIVE environment.
What value that?
The data generated to date clearly demonstrates the potential of homocitrullinated, as well as citrullinated, tumour-associated peptide epitopes to be developed for the treatment of solid cancers.
