A summary of the article is shown below:

Mycoplasma pneumoniae pneumonia (MPP) is the most common respiratory infection in young children and its incidence has increased worldwide. In this study, high expression of chemokine ligand 5 (CCL5) was observed in the serum of MPP patients, and its expression was positively correlated to DNA of M. pneumoniae (MP-DNA). In vitro, M. pneumoniae (MP) infection to A549 cells induced the expression of CCL5, chemokines receptor 4 (CCR4), nuclear factor-κB (NF-κB) nuclear protein, and phosphorylation of NF-κB-p65 (p-NF-κB-p65), whereas NF-κB cytoplasmic protein was decreased. On the contrary, treatment of hyperoside counteracted the induction of MP infection and promoted the proliferation of MP-infected A549 cells. Similarly, MP-induced IL-8 and TNF-α production was also markedly reduced by hyperoside. And CCR4 inhibitor AZD2098 had a better effect than hyperoside. In addition, CCL5 recombinant protein inhibited the effect of hyperoside to promote IL-8 and TNF-α production and CCR4 expression. These results indicated that CCL5 may be involved in the progression of MPP, and hyperoside was beneficial for MPP probably through CCL5-CCR4 interactions, which may provide a potential effective therapy for MPP.
