Overview of Gene Research
Dclre1c, also known as the gene encoding Artemis, is crucial for V(D)J recombination, an essential process in the differentiation and maturation of T and B cells. It is also involved in the repair of DNA double-strand breaks via the non-homologous end-joining (NHEJ) pathway [4,5,6,7].
In a phase 1-2 clinical study, lentiviral gene therapy using autologous CD34+ cells transfected with DCLRE1C was carried out in infants with Artemis-deficient severe combined immunodeficiency (ART-SCID). The therapy led to genetically corrected and functional T and B cells [1]. NK cells from DCLRE1C-deficient severe combined immunodeficiency (SCID) patients were found to be functional in inhibiting HCMV transmission between cells in vitro [2]. Dclre1c-deficient mice with an NOD genetic background, generated using Nuclease technology-mediated gene editing, exhibited a radiosensitive SCID phenotype with reduced T and B lymphocyte populations and were successfully engrafted with cell lines and patient-derived tumor xenografts [3].
In conclusion, Dclre1c is essential for V(D)J recombination and DNA repair, playing a key role in the development and function of the immune system. The study of Dclre1c-deficient mouse models and human patient-based research has provided insights into its role in immunodeficiency diseases, such as ART-SCID, and has potential implications for gene therapy and understanding immune-related disorders [1,2,3].
