Hypothesis
How does RNase L contribute to the immune response and clear viral infections?
Conclusion
RNase L has unconventional roles in degrading host mRNA, which activates immune responses and contributes to cell death.
Supporting Evidence
- RNase L cleaves both viral and host RNAs, which helps eliminate infections.
- Activation of RNase L leads to apoptosis of infected cells.
- RNA fragments generated by RNase L can activate immune signaling pathways.
- RNase L's activity is linked to various diseases, including cancer and autoimmune conditions.
Takeaway
RNase L helps our body fight infections by breaking down both virus and our own RNA, which can trigger cell death to get rid of the virus.
