Development of C-TILDA: A modified TILDA method for reservoir quantification in long term treated patients infected with subtype C HIV-1
2020
Abstract A better characterization of the HIV reservoir is pivotal for the development of effective eradication strategies. Accurate quantification of the latent reservoir remains challenging. Starting from a regular blood draw, the Tat/Rev induced limiting dilution assay (TILDA) combines serial dilution of CD4+ T cells with a PCR-based detection of HIV-1 spliced mRNA produced upon cell stimulation. Here we adapted the original protocol for HIV-1 subtype B to detect tat/rev mRNAs transcribed from reactivated latently infected cells in long term suppressed patients infected with HIV-1 subtype C. Given the heterogeneity of global HIV epidemiology, it is pivotal to develop assays with optimal performances also in patients infected with non-B subtypes. We observed that, in these patients infected with subtype C virus, the HIV reservoir quantified by TILDA correlates with both the time of virological suppression and CD4/CD8 ratio.
