  1. The data are shown as a fold change of chemokine mRNA expression in relation to the reference gene HPRT as measured by the RT-qPCR. Data are expressed as mean ± S.E.M. (Control: n = 6, APP-infected: n = 9). The significant differences (Mann–Whitney U test) between control and APP-infected pigs are marked with *P < 0.05, **P < 0.01. The values which were elevated between control and APP-infected pigs are highlighted in bold. LN, lymph node, n.d, non-detected.
