Differential expression of selected HSP40 and 70 isoforms in HIV-1-infected human PBMCs. Human PBMCs activated with PHA were infected with HIV-1NL4.3 virus at 0.1 MOI and cells were harvested at different days post-infection (day 1, 3, 5, and 7). Further, RNA was isolated and qRT-PCR was performed for selected HSP40 and HSP70 isoforms as described in the text. Differential expression of selected HSP40 (a) and HSP70 (b) isoforms presented as heat map using logarithmic-transformed fold change mean values (n = 3), respectively. The abscissa represents the number of days post-infection in the experiment and the ordinate represents different isoforms of HSP40 and HSP70, respectively
