In conclusion, IL-8 stimulates VEGF production in hBM-MSCs in part via the PI3K/Akt and MAPK/ERK signal transduction pathways and that administration of IL-8-treated hBM-MSCs increases angiogenesis after stroke.
No association of stroke was detected with the presence of C. pneumoniae, HCMV or enterovirus nucleic acids in the peripheral blood, C. pneumoniae IgM, IgG and IgA, the HSV IgG, the EBV IgG, or HHV-6 IgG antibody levels, the pathogen burden, the IL-8 or CD14 promoter polymorphisms, or with the serum levels of IL-8 in the overall study population.
