    Spinal V2b neurons reveal a role for ipsilateral inhibition in speed control

    Rebecca A Callahan et al.
    Two anatomically and genetically distinct subtypes of spinal V2b neurons provide inhibition onto motor circuits and serve as a brake on locomotor speed.

    USP49 potently stabilizes APOBEC3G protein by removing ubiquitin and inhibits HIV-1 replication

    Ting Pan et al.
    USP49 can increase A3G protein expression and enhance its anti-HIV-1 activity, which is also correlated with hypermutations and affects the HIV-1 latent reservoir.

    TERRA regulate the transcriptional landscape of pluripotent cells through TRF1-dependent recruitment of PRC2

    Rosa María Marión et al.
    Telomeric TRF1 controls the transcriptional programmes of pluripotent stem cells by recruiting PRC2 to pluripotency and differentiation genes by controlling the expression of those gene sites and the binding of TERRA RNAs to them.

    Insulin-like peptides and the mTOR-TFEB pathway protect Caenorhabditis elegans hermaphrodites from mating-induced death

    Cheng Shi et al.
    Hermaphroditic Caenorhabditis elegans slow the onset of mating-induced death through self-sperm-regulated insulin-like gene expression, which regulates the activity of the IIS/FOXO pathway, mTOR signaling, and the TFEB/HLH-30 transcription factor.
