    Olfactory receptor neurons use gain control and complementary kinetics to encode intermittent odorant stimuli

    Srinivas Gorur-Shandilya et al.
    Olfactory receptor neurons adapt to odorant mean and variance and use complementary kinetics to preserve the timing of odorant encounters, despite adaptation slowing down transduction.

    Optogenetic control shows that kinetic proofreading regulates the activity of the T cell receptor

    O Sascha Yousefi et al.
    Controlling the duration of ligand binding to the T cell receptor by light shows that T cells discriminate stimulatory from non-stimulatory ligands by measuring the dynamics of ligand binding.

    Kinetics of cytokine receptor trafficking determine signaling and functional selectivity

    Jonathan Martinez-Fabregas et al.
    Engineering cytokines to exhibit different receptor binding dwell times is a useful strategy to decouple their functional pleiotropy and reduce their toxicity in the clinic.

    Dissecting transcriptional amplification by MYC

    Zuqin Nie et al.
    Synthetic biology experiments show that MYC is a general transcription amplifier acting at two or more sites in the transcription-cycle and that MYC-turnover contributes to its activity.

    Control of AMPA receptor activity by the extracellular loops of auxiliary proteins

    Irene Riva et al.
    Glutamate receptor auxiliary proteins exert their effects on receptor gating through two divergent extracellular loops, explaining subunit specificity and allowing the construction of null versions that form complexes normally but do not modify receptor gating.

    Sex differences in cerebellar synaptic transmission and sex-specific responses to autism-linked Gabrb3 mutations in mice

    Audrey A Mercer et al.
    Male and female mice differ in basal cerebellar physiology, including the magnitude of synaptic excitation by metabotropic glutamate receptors, kinetics of synaptic inhibition, intrinsic properties, and responses to autism-linked mutations.

    The AMPA receptor-associated protein Shisa7 regulates hippocampal synaptic function and contextual memory

    Leanne J M Schmitz et al.
    Shisa7 is a bona-fide AMPAR modulatory protein affecting channel kinetics of hippocampal AMPARs, and is necessary for synaptic plasticity and memory recall.

    Mechanism of bidirectional thermotaxis in Escherichia coli

    Anja Paulick et al.
    The interplay between the opposing responses mediated by different chemoreceptors enables bacteria to swim towards a preferred temperature.
