The CAV2 Knockout Jurkat Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population targeting the CAV2 gene in the Jurkat T-lymphoblast cell line. This mixed population carries diverse mutations that collectively ablate caveolin-2 expression, preserving biological heterogeneity and avoiding clonal selection artifacts. It serves as a defined loss-of-function model for investigating caveolin-2-dependent processes.
The Jurkat cell line, originally derived from a T-cell leukemia patient, is a well-established system for T-cell receptor (TCR) signaling, activation, and leukemogenesis studies. As T lymphoblasts, these cells support physiological analyses of immune synapse formation, cytokine secretion, and apoptosis. This background provides a relevant context in which caveolin-2 organizes caveolae-mediated signaling platforms.
Caveolin-2 scaffolds caveolae together with caveolin-1 and cavin-1, directly interacting with Src family kinases, eNOS, integrins, and EGFR. It integrates upstream signals from integrins, TGF-beta, and Src to regulate MAPK (ERK1/2) and Akt pathways. Downstream, it modulates Ras, RhoA, and FAK activity, influencing cytoskeletal dynamics and transcriptional programs through FOXO and SREBP, ultimately affecting cyclin D1 expression and cell cycle progression.
In Jurkat cells, CAV2 knockout disrupts caveolae formation and signaling complex assembly, impairing TCR-mediated activation of Akt and ERK1/2 cascades. This disruption leads to altered proliferation and apoptosis, as measured by CFSE dilution and annexin V staining. The model therefore enables dissection of caveolin-2-dependent immune signaling and its contribution to leukemogenesis.
This polyclonal knockout cell population is suitable for T-cell activation assays, signal transduction analyses, proliferation and apoptosis studies, immune synapse examination, and drug target validation. Techniques such as phospho-specific flow cytometry (phospho-Akt, phospho-ERK), co-immunoprecipitation of caveolin-1/Src complexes, IL-2 ELISA, and immunofluorescence are readily applied. Combined with integrin ligation or pharmacological inhibition, it permits detailed interrogation of caveolin-regulated networks. Contact Ascent Research for further information.
