Genom-Editierung von CD4+-T-Zellen in der ex vivo-Tonsillenkultur
摘要
Genome editing has emerged as a cardinal tool to dissect molecular processes in mammalian cells. Standard gene editing approaches have however been inefficient in resting, non-dividing immune cells such as CD4 T helper cells. By combining an ex vivo tonsil culture system with highly efficient, activation-neutral gene editing using CRISPR-Cas9 technology, immune cell interactions of CD4 T cells and HIV pathology can now be dissected with high precision in a lymphoid tissue context.
