In 2017, reseаrchers cоmpаred аntimicrоbial peptide (AMP) gene expressiоn between the brains of young and old wild-type flies (drosophila). The graph below shows the result of this experiment. The y-axis shows fold-change in mRNA levels. Fold-change is a measure of how much something changes between two measurements. ** or *** = statistically significant Notice that the fold-change is positive and statistically significant for all the AMPs they measured. Thus, AMP gene expression is either higher in young brains or higher in old brains. The theory of inflammaging would suggest which result is most likely?
