Background of Jurkat-IL2P-Luc2 Cell Line

IL-2 was discovered through its function as a T cell growth factor and played a pivotal role in immune responses against pathogenic infection. Recognition and binding of the foreign antigens by the TCRs stimulate both the secretion of IL-2 and the expression of IL-2R on the T cell surface. Subsequently, the IL-2/IL-2R interaction activates the intracellular Ras/Raf/MAPK, JAK/STAT, and PI3K/AKT signal pathways, ultimately stimulating T cells' growth,differentiation, and survival. IL-2 acts on additional cell types, such as B cells, NK cells, monocytes and macrophages. It is primarily produced by activated CD4+ T cells but has also been reportedly made by CD8+ T cells, NK cells, dendritic cells, and macrophages. Interleukin-2 (IL-2) is one of the critical cytokines that has pleiotropic effects on the immune system. It has been approved for treating metastatic renal cell carcinoma and metastatic melanoma. While improved IL-2 formulations can be used as monotherapy, their combination with other anti-cancer immunotherapies such as adoptive cell transfer protocols, antigen-specific vaccination, and blocking immune checkpoint inhibitory molecules such as cytotoxic T lymphocyte associated antigen 4 (CTLA-4) and programmed death 1 (PD-1) monoclonal antibody will hold promise for the treatment of metastatic cancer. Although comprehensive studies of IL-2 on the immune system have established the use of IL-2 in cancer immunotherapy, there are still some sharp hurdles for future research.

Cell Line Generation

The Jurkat-IL2P-Luc2 cell line was generated using lentivirus methods.

Characterization

Figure 1. Jurkat-IL2P-Luc2 cell line was seed into the 96-well plate and treated with PMA at a maximum concentration of 30nM, and Ionomycin at a full concentration 100ng/ml diluted 3.16-fold for 16 hours, then readout with Bright-Glo system.

Figure 2. Jurkat-IL2P-Luc2 cell line was co-cultured with Raji OS8 in the 96-well plate for 16 hours, then readout with Bright-Glo system.

Cell Resuscitation

1. Prewarm culture medium (RPMI1640 supplemented with 10%FBS, 300ug/ml Hygromycin B)in a 37°C water bath. 2. Thaw the frozen vial in a 37°C water bath for 1-2 minutes. 3. Transfer the vial into biosafety cabinet, and wipe the surface with 70% ethanol. 4. Unscrew the top of the vial and transfer the cell suspension gently into a sterile centrifuge tube containing 9.0mL complete culture medium. 5. Spin at ~ 125 × g for 5-7 minutes at room temperature, and discard the supernatant without disturbing the pellet. 6. Resuspend cell pellet with the appropriate volume of complete medium and transfer the cell suspension into a T25 culture flask. 7. Incubate the flask at 37°C, 5% CO2 incubator. 8. Split saturated culture 1:4-1:5 every 2-3 days; seed out at about 1-3 × 105 cells/mL.

Cell Freezing

1. Prepare the freezing medium (RPMI1640 + 20% FBS + 10% DMSO) fresh immediately before use. 2. Keep the freezing medium on ice and label cryovials. 3. Transfer cells to a sterile, conical centrifuge tube, and count the cells. 4. Centrifuge the cells at 250×g for 5 minutes at room temperature and carefully aspirate off the medium. 5. Resuspend the cells at a density of at least 3×106 cells/mL in chilled freezing medium. 6. Aliquot 1 mL of the cell suspension into each cryovial. 7. Freeze cells in the CoolCell freezing container overnight in a -80°C freezer. 8. Transfer vials to liquid nitrogen for long-term storage
