Allogeneic Treg do not prevent their own rejection in immunocompetent hosts - HLA matching or HLA editing required for optional function!

A beautiful collaboration with Fadi Issa & Joanna Hester’s team @ox.ac.uk. @dlwagnerlabs.bsky.social

@dlwagnerlabs.bsky.social on tour! 🌍🇩🇪🇺🇸

We had a great time at the Annual Congress of the European Society for Gene and Cell Therapy #ESGCT2025 in Sevilla. 🇪🇸

Super proud of everyone who presented their projects & grateful for working with this amazing team: science and good vibes! 🧬🧪💙

Our team is on their way to the ESGCT conference 2025! Excited for this upcoming week full of science, talks, and inspiring discussions with the cell & gene therapy community!
Starting with the HDR workshop - talks by Isabell (‘one-pot’ PASTA) & Viktor
(BEKI) + posters by Ana, Lily, Jonas and Laura

Super-large targeted Knock-Ins in primary T cells, with multigene inserts >8kb, in a single reaction. HOW?? 🙀

Combine simple CRISPR-HDR & Integrases for one-pot PASTA🍝

= Programmable And Site-specific Transgene Addition. 😎

Ultra-depletion of TCR+ cells from allogeneic CAR T cells to prevent GvHD.... LOG-FOLD BETTER THAN MACS!!!

HOW? => Addition of short-lived TCR-specific CAR NK-92 cells during expansion.

How everything started. My first 1st 🤟
Lab History pt. 1
2022 – 🚨 Our first paper is out! 🚨

virus-free CAR knock-in to TRAC locus of primary human T cells with CRISPR-HDR.

➡️ >50% TRAC CD19-CAR T cells through pharmacological modulation

🧬 A key step toward scalable, non-viral CAR-T cell therapies.
