Hypothesis
Does the lysozyme LYS-7 play a role in mediating resistance to C. neoformans and susceptibility to Salmonella Typhimurium in C. elegans?
Conclusion
The study found that the loss of LYS-7 increases resistance to Salmonella Typhimurium while making C. elegans more susceptible to C. neoformans.
Supporting Evidence
- LYS-7 knockout animals are hypersusceptible to C. neoformans.
- LYS-7 knockout animals exhibit enhanced resistance to S. Typhimurium.
- The resistance to S. Typhimurium is mediated by genetic compensation involving other genes.
Takeaway
This study shows that a gene in worms helps them fight off one germ but makes them more vulnerable to another, showing a trade-off in their immune system.
Methodology
The researchers used knockout strains of C. elegans to assess survival against different pathogens and measured gene expression changes.
