Points for discussion • Immune activationdrivesdiseaseprogression. • Classical (CD14+CD16-) vs non classical (CD14+/CD16+) monocytes: whatistheirrole in immune activation? • Increasedlevel of blood non classicalmonocytesiscorrelated with diseaseprogression. Non classicalM-DC8+ monocytes accumulate in the peripheralblood of viremicuntreatedpatients (Dutertre et al. 2013). • Betterdefinition of monocyte/macrophages and DC subsets in severalanatomicalcompartment…and theirroleasviralreservoirs. • Focus on alternative approaches to purge HIV reservoirs.
