ADIRF Knockout Jurkat Polyclonal Cells constitute a CRISPR/Cas9-edited polyclonal knockout cell population in which the ADIRF gene has been disrupted via targeted Cas9-mediated cleavage. This pooled format provides a heterogeneous mixture of Jurkat cells carrying various loss-of-function mutations at the ADIRF locus, avoiding clonal artifacts while enabling functional interrogation of ADIRF in a T-cell context. These polyclonal knockout cells serve as a versatile tool for researchers examining adipogenesis-associated transcription factors outside their classical lineage.
The parental Jurkat cell line is an immortalized human T-lymphocyte model originally derived from an acute T-cell leukemia patient. Jurkat cells are widely employed in immunology to dissect T-cell receptor (TCR) signaling, cytokine production, and adaptive immune responses due to their robust growth and well-characterized signaling networks. Their genetic tractability and responsiveness to activation stimuli make them a preferred platform for CRISPR-based knockout studies exploring T-cell function and beyond.
ADIRF encodes a transcription factor that is a critical effector of adipogenic differentiation, functioning downstream of master regulators PPAR?? and C/EBP??. Mechanistically, ADIRF interacts with PPAR??, C/EBP??, and the coactivator PGC-1?? to promote the expression of genes essential for lipid metabolism and insulin sensitivity, including FABP4, ADIPOQ, LPL, and GLUT4. The ADIRF-PPAR?? axis is central to adipocyte maturation and energy homeostasis, linking insulin signaling to terminal differentiation.
In the Jurkat T-cell environment, this ADIRF knockout model provides an opportunity to explore potential non-adipogenic functions of ADIRF, such as its involvement in metabolic reprogramming or differentiation pathways that may intersect with T-cell activation and metabolism. Given that T-cell responses require dynamic metabolic shifts, disruption of ADIRF may influence expression of metabolic targets like FABP4 or GLUT4, offering a unique system to study the interplay between immunometabolism and adipogenic regulators.
Researchers can utilize these polyclonal knockout cells in a range of quantitative assays to characterize ADIRF-dependent effects. Typical applications include RT-qPCR profiling of downstream targets such as FABP4 and ADIPOQ, Western blot analysis of PPAR?? and ADIRF protein levels, and flow cytometric assessment of T-cell activation markers upon TCR engagement. Additionally, proliferation assays and gene expression microarrays can provide insights into broad transcriptional changes. For further details or custom requests, please contact Ascent Research.
