Abstract
Modifying gene expression in lymphocytes is essential for immunological research; however, gene transfection methods for group 2 innate lymphoid cells (ILC2s) are not well established. Here, we present a protocol utilizing lentiviral vectors to introduce genes into human ILC2s. We detail steps for lentiviral solution preparation, transfection, and selection of transfected cells. This protocol allows overexpression or suppression of specific genes and evaluation of the changes in ILC2 biology. For complete details on the use and execution of this protocol, please refer to Irie et al. (2023).1.
