    Discovery and validation of sub-threshold genome-wide association study loci using epigenomic signatures

    Xinchen Wang, Nathan R Tucker ... Laurie A Boyer
    Epigenomic signatures overlapping disease-associated variants from genome-wide association studies help prioritize new variants in sub-threshold loci whose biological relevance is experimentally confirmed.

    Brain state and cortical layer-specific mechanisms underlying perception at threshold

    Mitchell P Morton, Sachira Denagamage ... Anirvan S Nandy
    States of elevated arousal and stable retinal images allow enhanced processing of threshold stimuli in the laminar microcircuits of area V4.

    Calibration of cell-intrinsic interleukin-2 response thresholds guides design of a regulatory T cell biased agonist

    Caleb R Glassman, Leon Su ... K Christopher Garcia
    A panel of interleukin-2 partial agonists designed to exploit distinct immune cell response thresholds enabled selective activation of regulatory T cells in vivo.

    Stochastic parabolic growth promotes coexistence and a relaxed error threshold in RNA-like replicator populations

    Mátyás Paczkó, Eörs Szathmáry, András Szilágyi
    An individual-based model framework of sub-exponentially growing replicator systems suggests that parabolic dynamics could have been able to maintain genetic diversity and circumvent the error threshold problem during early evolution.

    Removal of inhibition uncovers latent movement potential during preparation

    Uday K Jagadisan, Neeraj J Gandhi
    Non-invasive disinhibition of the oculomotor system shows that ongoing preparatory activity in the superior colliculus has movement-generating potential and need not rise to threshold in order to produce a saccade.

    Drift and termination of spiral waves in optogenetically modified cardiac tissue at sub-threshold illumination

    Sayedeh Hussaini, Vishalini Venkatesan ... Stefan Luther
    Excitability gradients in heart tissue, imposed by structured sub-threshold optogenetic stimulation, induce drift and termination of spiral waves, thus providing an explanation for successful optogenetic defibrillation in small animal hearts.

    Improved T cell receptor antigen pairing through data-driven filtering of sequencing information from single cells

    Helle Rus Povlsen, Amalie Kai Bentzen ... Morten Nielsen
    A bioinformatics approach shows how to reduce noise in single-cell TCR-pMHC specificity data while retaining sensitivity toward cross-binding events to facilitate investigation of the rules governing TCR-pMHC binding.

    A re-inducible gap gene cascade patterns the anterior–posterior axis of insects in a threshold-free fashion

    Alena Boos, Jutta Distler ... Ezzat El-Sherif
    The body axis of insects is divided into different fates using a self-regulatory and threshold-free mechanism.

    Multiple UBX proteins reduce the ubiquitin threshold of the mammalian p97-UFD1-NPL4 unfoldase

    Ryo Fujisawa, Cristian Polo Rivera, Karim PM Labib
    UBX proteins reduce the ubiquitin threshold of mammalian p97-UFD1-NPL4.

    Galectin-9 regulates the threshold of B cell activation and autoimmunity

    Logan K Smith, Kareem Fawaz, Bebhinn Treanor
    Galectin-9-deficient mice develop spontaneous autoimmunity, driven by a decreased threshold of B cell activation and enhanced auto-antigen delivery to the spleen by increased B1a-derived autoantibodies.
