چکیده
|
Despite the success of antiretroviral therapy (art),it does not cure human immunodeficiency virus (hiv) and discontinuation results in viral rebound. follicular dendritic cells (fdc) are in direct contact with cd4+ t cells and they retain intact antigen for prolonged periods. we found that human fdc isolated from patients on art retain infectious hiv within a non-degradative cycling compartment and transmit infectious virus to uninfected cd4 t cells in vitro. importantly,treatment of the hiv+ fdc with a soluble complement receptor 2 purges the fdc of hiv virions and prevents viral transmission in vitro. our results provide an explanation for how fdc can retain infectious hiv for extended periods and suggest a therapeutic strategy to achieve cure in hiv-infected humans. © 2015 heesters et al.
