Handling procedures
- Initial handling guidelines
Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.
1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.- Subculture guidelines
- All seeding densities should be based on cell counts gained by established methods.
- A guide seeding density of 2x104 cells/cm2 is recommended.
- Cells should be passaged when they have achieved 80-90% confluence.
- Do not allow the cell density to exceed 7x104 cells/cm2.
- Culture medium
- F-12K + 10% FBS
- Cryopreservation medium
- Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.

- Activity summary
The transcription factor IRF7 also known as Interferon Regulatory Factor 7 plays a significant role in the regulation of type I interferon genes. This protein acts as an important modulator of the immune response specifically during viral infections. The molecular weight of IRF7 is approximately 54 kDa. It is predominantly expressed in lymphoid tissues such as the spleen and thymus and is also found in other immune cells like B cells and dendritic cells. The expression of IRF7 is induced by pathogen-associated molecular patterns which stimulate the activation of immune signaling pathways.
- Biological function summary
IRF7 activates and modulates the expression of type I interferons and other cytokines important for antiviral defense. This protein can form part of a larger complex with other IRF family members to enhance its effect on gene transcription. IRF7 operates through its interaction with transcriptional coactivators allowing it to execute its function as a transcriptional activator reinforcing the immune system's response to infectious agents.
- Pathways
IRF7 plays a critical role in the Toll-like receptor (TLR) signaling pathway and retinoic acid-inducible gene I (RIG-I) pathway. It directly interacts with MyD88 and IRAK1 proteins linking it to signal transduction pathways that lead to interferon-beta production. The activation of IRF7 in these pathways also strengthens the body's defense mechanism by enhancing the transcription of antiviral genes forming a robust antibacterial and antiviral environment within the host.
- Associated diseases and disorders
IRF7's function is implicated in autoimmune diseases and specific cancers. For autoimmune conditions like systemic lupus erythematosus (SLE) dysregulated IRF7 activity is observed leading to an aberrant interferon response. It connects with proteins such as IRF5 which has its expressions elevated in affected patients. In relation to cancer IRF7 can impact tumor progression particularly in breast cancer through modulation of immune surveillance functions. Its interaction with interferon pathways becomes a double-edged sword affecting tumor immunity and progression.
