Abstract
APDS2 is caused by mutations in PIK3R1 gene resulting in constitutive PI3Kδ activation. PI3Kδ is predominantly expressed in leukocytes and plays critical roles in regulating immune responses. Here we first derived fibroblast primary cells from a skin biopsy of a patient carrying a heterozygous single T deletion in intron 11 of the PIK3R1 gene. We next present the derivation of an induced pluripotent stem cell (iPS) line using a non-integrative reprogramming technology. Pluripotent-related hallmarks are further shown, including: iPSCs self-renewal and expression of pluripotent and differentiation markers after in vitro differentiation towards embryonic germ layers, assessed by RT-PCR and immunofluorescence.
Description
This article reports the generation and characterization of an induced pluripotent stem cell line, CVTTHi001-A, derived from primary fibroblasts obtained from a patient with activated PI3 kinase delta syndrome type 2 caused by a PIK3R1 variant. Fibroblasts were reprogrammed using a non-integrative Sendai virus approach. The resulting iPSC line showed pluripotency marker expression, self-renewal capacity and differentiation potential toward the three embryonic germ layers, providing a disease-specific cellular model for APDS2.
