The decameric repeat (DR) of PSGL-1 functions as a basic antiviral unit in restricting HIV-1 infectivity

Han Yang, Leanna Sealey, Yajing Fu, Bryan M. Delfing, Christopher Lockhart, Linda D. Chilin, Sameer Tiwari, Mohsin Saleet Jafri, Dmitri K. Klimov, Yuntao Wu

This study identifies the decameric repeat (DR) of PSGL-1 as an essential antiviral unit that restricts HIV-1 infectivity by hindering virion attachment to target cells.

CD34 serves as an intrinsic innate immune guardrail protecting stem cells from replicating retroviruses

Sijia He, Amrita Haikerwal, Sameer Tiwari, Deemah Dabbagh, Mohammed Z. Alam, Janice L. Yoon, Brian Hetrick, Yang Han, Liang Shan, Christopher Lockhart, Yuntao Wu

The paper identifies CD34 as an intrinsic innate immune factor that restricts retrovirus replication in stem cells by inactivating progeny virions.

PSGL-1 excludes HIV Env from virion surface through spatial hindrance involving structural folding of the decameric repeats (DR)

Sameer Tiwari, Bryan M. Delfing, Han Yang, Christopher Lockhart, Amrita Haikerwal, Abdul A. Waheed, Eric O. Freed, Mohsin Saleet Jafri, Dmitri K. Klimov, Yuntao Wu

This study identifies PSGL-1's decameric repeats as critical for excluding HIV Env from virions through structural folding that spatially hinders Env incorporation.
