A CRISPR screen of HIV dependency factors reveals CCNT1 is non-essential in T cells but required for HIV-1 reactivation from latency [RNA-Seq]

Project description:We sought to explore the hypothesis that host factors required for HIV-1 replication also play a role in latency reversal. Using a CRISPR gene library of putative HIV dependency factors, we performed a screen to identify genes required for latency reactivation. We identified several HIV- 1 dependency factors that play a key role in HIV-1 latency reactivation including ELL, UBE2M, TBL1XR1, HDAC3, AMBRA1, and ALYREF. Knockout of Cyclin T1 (CCNT1), a component of the P-TEFb complex important for transcription elongation, was the top hit in the screen and had the largest effect on HIV latency reversal with a wide variety of latency reversal agents. Moreover, CCNT1 knockout prevents latency reactivation in a primary CD4+ T cell model of HIV latency without affecting activation of these cells. RNA sequencing data showed that CCNT1 regulates HIV-1 proviral genes to a larger extent than any other host gene and had no significant effects on RNA transcripts in primary T cells after activation. We conclude that CCNT1 function is redundant in T cells but is absolutely required for HIV latency reversal.

A Virus-Packageable CRISPR System Identifies Host Dependency Factors Co-opted by Multiple HIV-1 Strains

Project description:The goal of this CRISPR-based screen (HIV-CRISPR) is to identify HIV-1 dependency factors by evaluating multiple pathways simultaneously. Here are Illumina sequencing data and counts files from HIV-CRISPR screens using a guide RNA library targeting the whole genome (TKOv3), a custom guide RNA library targeting human epigenome genes (HuEpi), a custom guide RNA library targeting interferon-stimulated genes (PIKA), and a custom guide RNA library of genes containing of a subset of each of the aforementioned libraries designed to target human dependency factors (HIVDEP). The HIV-CRISPR screens described here were performed in clonal ZAP knockout Jurkat cell lines as ZAP inhibition of the HIV-CRISPR vector has been previously described (PMID: 30520725).

A Virus-Packageable CRISPR Screen Identifies Host Factors Mediating Interferon Inhibition of HIV

Project description:Interferon (IFN) inhibits HIV replication by inducing an array of antiviral effectors. Here we describe a novel CRISPR knockout screening approach to identify the ensemble of these HIV restriction factors. We assembled a CRISPR sgRNA library specific for Interferon Stimulated Genes (ISGs) into a modified lentiviral vector that allows for packaging of sgRNA-encoding genomes in trans into budding HIV-1 particles. We observed that knockout of Zinc Antiviral Protein (ZAP) improved the performance of the screen due to ZAP-mediated inhibition of the vector. We identify a small panel of IFN-induced HIV restriction factors, including MxB, IFITM1, Tetherin/BST2 and TRIM5 which together explain the inhibitory effects of IFN on the HIV-1 LAI strain in THP-1 cells. Further, we identify novel HIV dependency factors, including SEC62 and TLR2. The ability of IFN-induced restriction factors to inhibit an HIV strain to replicate in human cells suggests that these human restriction factors are incompletely antagonized.
