The AIF1L Knockout Jurkat Polyclonal Cells represent a CRISPR/Cas9-edited polyclonal knockout cell population engineered for loss-of-function studies of the AIF1L gene in a human T-cell context. This model is generated through CRISPR/Cas9-mediated gene disruption in the Jurkat cell line, yielding a heterogeneous pool of edited cells that enables investigation of AIF1L function without the biases of single-clone selection. The polyclonal format preserves genetic diversity while eliminating AIF1L expression, offering a robust platform for studying cytoskeletal dynamics and immune cell activation.
The parental Jurkat cell line is a widely utilized human leukemic T-cell line derived from peripheral blood of a patient with acute T-cell leukemia. These cells express canonical T-cell surface markers, including CD3 and CD4, and retain key features of T-cell receptor (TCR) signaling, making them a preferred host for investigating TCR-dependent pathways, apoptosis, and cytokine production. Jurkat cells are extensively employed in immunology research, particularly for studying T-cell activation, HIV infection mechanisms, and the molecular events governing immune responses.
AIF1L is an actin-binding protein that directly interacts with actin filaments and participates in cytoskeletal reorganization upon T-cell activation. It functions downstream of TCR signaling and CD3/CD28 costimulation, and is influenced by cytokines such as IL-2. Within the actin cytoskeleton regulatory network, AIF1L associates with cofilin and the Arp2/3 complex, modulating actin dynamics through Rho GTPase signaling. Representative pathway components include RAC1, RHOA, CDC42, and WASP, which collectively orchestrate actin remodeling. AIF1L??s interaction with F-actin promotes processes like immunological synapse formation and cell migration, and its disruption leads to impaired actin reorganization and diminished T-cell functional responses.
In the Jurkat T-lymphocyte background, knockout of AIF1L provides a physiologically relevant model to dissect actin-dependent mechanisms underlying T-cell function. Loss of AIF1L is expected to perturb cytoskeletal dynamics, thereby affecting immunological synapse assembly, TCR-mediated signaling strength, and cytoskeleton-dependent effector responses. This model enables the study of how AIF1L coordinates with Rho GTPases and actin remodeling proteins to regulate T-cell activation, migration, and cytokine secretion, with implications for understanding inflammatory diseases, autoimmune disorders, and graft rejection.
The AIF1L Knockout Jurkat Polyclonal Cells are suitable for a wide range of experimental applications, including flow cytometric analysis of T-cell activation markers (e.g., CD69 and CD25), F-actin phalloidin staining to visualize cytoskeletal architecture, Transwell migration assays to evaluate cell motility, and Western blotting for actin-binding proteins. Additionally, cytokine ELISA assays can be used to quantify altered secretion profiles, while live-cell imaging enables dynamic observation of cytoskeletal remodeling. These tools facilitate detailed mechanistic studies of AIF1L in immune cell signaling and actin regulation. For further technical inquiries, please contact Ascent Research.
