    Heterogeneous T cell motility behaviors emerge from a coupling between speed and turning in vivo

    Elizabeth R Jerison, Stephen R Quake
    Motile interstitial T cells in live zebrafish access a broad range of length-scales due to long-lived cell-intrinsic variation in speed, and a coupling between speed and directional persistence.

    Fibroblastic reticular cell-derived lysophosphatidic acid regulates confined intranodal T-cell motility

    Akira Takeda et al.
    A lipid mediator lysophosphatidic acid (LPA) derived from fibroblastic reticular cells regulates T-cell movement through the densely packed reticular network in lymph nodes in a manner dependent on the LPA receptor LPA2-ROCK-myosin II.

    Intermittent Ca2+ signals mediated by Orai1 regulate basal T cell motility

    Tobias X Dong et al.
    Orai1 channels activate intermittently in motile T cells, generating calcium transients, detected by a novel genetically encoded indicator and inducing pauses that favor antigen scanning.

    Mucosal-associated invariant T (MAIT) cells mediate protective host responses in sepsis

    Shubhanshi Trivedi et al.
    Mucosal-associated invariant T (MAIT) cells, highly activated and dysfunctional in sepsis patients, contribute to tissue-specific cytokine responses that are protective against mortality during experimental sepsis.

    T-cell calcium dynamics visualized in a ratiometric tdTomato-GCaMP6f transgenic reporter mouse

    Tobias X Dong et al.
    Salsa6f is a novel, ratiometric genetically encoded Ca2+ indicator that combines the power of ratiometric chemical Ca2+ indicators with the ability, when expressed transgenically, to image cellular Ca2+ signals amid complex tissue environments in vivo.

    Ca2+ signaling driving pacemaker activity in submucosal interstitial cells of Cajal in the murine colon

    Salah A Baker et al.
    An optogenetic dual-color Ca2+-imaging approach shows how submucosal pacemaker-cells, interstitial cells of Cajal, modulate smooth-muscle responses and drive colonic motility via complex Ca2+ signaling.

    Influenza A virus surface proteins are organized to help penetrate host mucus

    Michael D Vahey, Daniel A Fletcher
    By distributing receptor-binding and receptor-destroying proteins asymmetrically on their surface, filamentous influenza A virus particles create a Brownian ratchet that facilitates their passage through mucus.

    Sperm chemotaxis is driven by the slope of the chemoattractant concentration field

    Héctor Vicente Ramírez-Gómez et al.
    The slope of the chemoattractant concentration gradient is a driving force for sperm chemotaxis, by coordinating the entrainment of information flow between sensing, signaling and motility.

    Crucial role for T cell-intrinsic IL-18R-MyD88 signaling in cognate immune response to intracellular parasite infection

    Ana-Carolina Oliveira et al.
    Development of a robust Th1 response to infection against an intracellular parasite requires T-cell intrinsic MyD88 signaling, mostly through the upstream IL-18 receptor, for the induction of genes involved in proliferation, cytokine production and migration.

    Tuning of in vivo cognate B-T cell interactions by Intersectin 2 is required for effective anti-viral B cell immunity

    Marianne Burbage et al.
    Intersectin2 deficiency is associated with impaired humoral responses to viral infection and B-cell-intrisic defects in germinal centre formation, resulting from the reduced ability of intersectin2-KO B cells to establish cognate interactions with helper T cells.
