Frontiers of Science: Reprogramming T Cells with CRISPR
Associate Prof. Alexander Marson, University of California, San Francisco, US
host: Riitta Lahesmaa (riitta.lahesmaa@utu.fi)
The goal of Marson’s lab is to understand genetic circuits that control human immune cell function in health and disease. They employ genomic techniques to map epigenetic circuits that establish highly specialized cell identities. Marson’s team have begun to identify autoimmunity risk variants that disrupt immune cell circuits, and how pathogenic circuits may be targeted with novel therapeutics. His lab has developed new tools for CRISPR genome engineering in primary human T cells and they are now pursuing a comprehensive strategy to test how coding and non-coding genetic variation controls functional programs in the immune system. Genome engineered human T cells hold great potential for the next generation of cell-based therapies for cancer, autoimmunity, and infectious diseases.

Genral info regarding the Frontiers of Science eTALKs
- Registration is obligatory and links to register to all Frontiers of Science Autumn 2020 seminars are available in BioCity Turku webpage (https://biocityturku.fi/biocityevents/frontiers-of-science-seminars/programme-autumn-2020/) and in our news feed.
- Registration closes two days before the event and link to join zoom will be sent to the participants one day in advance.
- Microphones and cameras need to be turned off during the presentation, but the audience is welcome to ask questions after the talk, preferably with video turned on to make the discussion as interactive as possible.
- If you are a student and need a certificate for your attendance, please fill in your student number when registering to the events. After the seminar season is over, please contact BioCity Turku coordinator biocityturku@bioscience.fi.
If you have any questions regarding our Frontiers of Science eTALK seminar series, please don’t hesitate to contact BioCity Turku coordinator biocityturku@bioscience.fi
