    Genetic, cellular, and structural characterization of the membrane potential-dependent cell-penetrating peptide translocation pore

    Evgeniya Trofimenko, Gianvito Grasso ... Christian Widmann
    Cationic cell-penetrating peptides (CPPs) enter cells through ~2 (–5)-nm-wide water pores induced by the strong negative plasma membrane potential that CPPs and the activity of potassium channels generate.

    Antagonism in olfactory receptor neurons and its implications for the perception of odor mixtures

    Gautam Reddy, Joseph D Zak ... Venkatesh N Murthy
    Computational and theoretical analyses offer novel and unexpected insight into how complex, naturally occurring odor mixtures are parsed and normalized at the very first stage of olfaction.

    Identification of protein-protected mRNA fragments and structured excised intron RNAs in human plasma by TGIRT-seq peak calling

    Jun Yao, Douglas C Wu ... Alan M Lambowitz
    Human plasma contains protein-protected mRNA fragments, myriad repeat RNAs, and novel intron RNAs, including a family of structured full-length excised introns, some corresponding to mirtron pre-miRNAs and agotrons.

    Quantitative modeling of the effect of antigen dosage on B-cell affinity distributions in maturating germinal centers

    Marco Molari, Klaus Eyer ... Rémi Monasson
    Detailed and inferred model reproduces B-cell affinity distributions measured in mice immunized according to various protocols and explains non-monotonous effects of antigen dosage on maturation.

    A curative combination cancer therapy achieves high fractional cell killing through low cross-resistance and drug additivity

    Adam C Palmer, Christopher Chidley, Peter K Sorger
    Drugs in a curative chemotherapy regimen are independently effective and resisted by different mechanisms, so cancer cells have little chance of surviving all drugs, and this benefit occurs without synergistic interactions.

    Single-cell expression profiling reveals dynamic flux of cardiac stromal, vascular and immune cells in health and injury

    Nona Farbehi, Ralph Patrick ... Richard P Harvey
    Comprehensive scRNA-seq analysis of cardiac stromal cells in healthy and injured hearts reveals novel cell types and non-linear cell dynamics, providing new insights into cardiac inflammation, fibrosis and repair.
