[13] There were 8 children with AHO from MRSA. [13] The investigators found that S. aureus infections were associated with over-expression of innate immunity and under-expression of genes related to adaptive immunity, which is consistent with the findings of our study. [13] We found three over-expressed genes in common with the study of Ardura et al.: LCN2, MYL9, and RETN. [13] It is important to note that both of the aforementioned used PBMC transcription, rather than assessing whole blood RNA [12], [13]. Here, RETN is linked to pseudohypoparathyroidism type 1A.
