Thors’ contributions VAG conceived, made and performed the experiments, analysed the information and wrote the paper. PA and MSW conceived experiments and wrote the paper. All authors study and approved the final manuscript. Acknowledgements We thank Samantha Barichievy for early technical help relating to operating with HIV-1, Mariano A. Garcia-Blanco for anti-Tat-SF1 antibodies, and Heather B. Miller for a Tat-SF1 Western blot protocol. Financial help for this operate from the South African National Study Foundation, Poliomyelitis Research Foundation and Health-related Analysis Council is gratefully acknowledged. Moreover, VAG was supported by bursaries in the Poliomyelitis Investigation Foundation, Mellon Foundation and AIDS Study Initiative. The funders had no function in study design and style, data collection and evaluation, choice to publish, or preparation of your manuscript.
