    One-step efficient generation of dual-function conditional knockout and geno-tagging alleles in zebrafish

    Wenyuan Li et al.
    Conditional gene knockout in combination with fluorescent labeling of different alleles can be achieved with high efficiency in zebrafish through NHEJ-mediated targeted insertion using a CRISPR/Cas system.

    Targeted, homology-driven gene insertion in stem cells by ZFN-loaded ‘all-in-one’ lentiviral vectors

    Yujia Cai et al.
    Building on previous work (Cai et al., 2014), HIV-derived lentiviral vectors are harnessed to insert user-defined genes into a safe locus in the genome of human stem cells.

    Mannose receptor is an HIV restriction factor counteracted by Vpr in macrophages

    Jay Lubow et al.
    Interactions between HIV-1 Env and human mannose receptor enhance HIV entry but restrict viral egress and spread in the absence of Vpr.

    Virus infection of the CNS disrupts the immune-neural-synaptic axis via induction of pleiotropic gene regulation of host responses

    Olga A Maximova et al.
    Virus infection of the central nervous system disrupts the homeostasis of the immune-neural-synaptic axis via induction of pleiotropic genes with an unintended off-target negative impact on the neurotransmission.

    Attenuation of AMPK signaling by ROQUIN promotes T follicular helper cell formation

    Roybel R Ramiscal et al.
    The ubiquitin ligase ROQUIN cross-talks with cellular metabolic signals to generate protective T cell-dependent antibody responses.

    HIV-1 integrase tetramers are the antiviral target of pyridine-based allosteric integrase inhibitors

    Pratibha C Koneru et al.
    Pyridine-based allosteric inhibitors selectively target HIV-1 integrase tetramers and exhibit enhanced antiviral activity against a dolutegravir resistant mutant virus indicating potential clinical benefits for combining these two classes of inhibitors.

    RNA-dependent RNA targeting by CRISPR-Cas9

    Steven C Strutt et al.
    Divergent Cas9 enzymes direct site-specific single-stranded RNA cleavage, reducing infection by RNA phage in vivo and enabling programmable, PAM-independent repression of gene expression in bacteria.

    Complement and CD4+ T cells drive context-specific corneal sensory neuropathy

    Derek J Royer et al.
    The complement pathway can contribute to corneal sensation loss and nerve damage during ocular surface inflammation.

    Identification of NPC1 as the target of U18666A, an inhibitor of lysosomal cholesterol export and Ebola infection

    Feiran Lu et al.
    A nanomolar inhibitor of cholesterol transport out of endosomes/lysosomes can be crosslinked to the “sterol-sensing domain” of NPC1, which implicates this domain in the transmembrane transport of cholesterol.

    Defective lytic transglycosylase disrupts cell morphogenesis by hindering cell wall de-O-acetylation in Neisseria meningitidis

    Allison Hillary Williams et al.
    Lytic transglycosylase enhances the activity of its protein partner, and its catalytic domain can be targeted to disrupt cell-wall integrity, protein partner function, and bacterial survival (Neisseria meningitidis) in hosts.
