    Unified mechanisms for self-RNA recognition by RIG-I Singleton-Merten syndrome variants

    Charlotte Lässig et al.
    RIG-I Singleton-Merten syndrome mutations either mimic or freeze the protein in an ATP-bound state and lead to autoimmune signalling through a gain-of-function recognition of self-RNA.

    ATP hydrolysis by the viral RNA sensor RIG-I prevents unintentional recognition of self-RNA

    Charlotte Lässig et al.
    Mutations within the ATPase domain of RIG-I in patients with Singleton-Merten Syndrome prevent ATP-hydrolysis dependent dissociation of RIG-I from double-stranded RNA and lead to unintentional constitutive signaling through increased binding of endogenous RNA.

    Self-recognition drives the preferential accumulation of promiscuous CD4+ T-cells in aged mice

    Neha R Deshpande et al.
    Higher affinity for self-pMHC complexes and broader promiscuity for foreign-pMHC complexes imparts a fitness advantage within the CD4+ T cell compartment in older mice.

    Structural basis of host recognition and biofilm formation by Salmonella Saf pili

    Longhui Zeng et al.
    SafDAA-SafDAA structure and functional characterizations reveal a pili-mediated inter-cellular oligomerization mechanism for bacterial aggregation and biofilm formation in Salmonella enterica.

    A herpesvirus encoded Qa-1 mimic inhibits natural killer cell cytotoxicity through CD94/NKG2A receptor engagement

    Xiaoli Wang et al.
    Rodent herpesvirus Peru overcomes NK ‘missing-self’ killing using a non-classical MHC-I like protein resistant todownregulation by its own ubiquitin ligase that potently sabotages antigen presentation to T-cells.

    γ-Protocadherin structural diversity and functional implications

    Kerry Marie Goodman et al.
    Crystal structures of γ-protocadherin cell-cell recognition dimers reveal the determinants of clustered protocadherin homophilic specificity and cis interaction region structures alongside mutagenesis data identify the putative cis interface.

    Protocadherin-dependent dendritic self-avoidance regulates neural connectivity and circuit function

    Dimitar Kostadinov, Joshua R Sanes
    Patterning of dendrites by protocadherin-dependent self-avoidance and self/non-self discrimination is required for proper function of a retinal circuit that computes the direction of motion.

    Infectious polymorphic toxins delivered by outer membrane exchange discriminate kin in myxobacteria

    Christopher N Vassallo et al.
    Serial cell-to-cell transfer of lipoprotein toxins by outer membrane exchange provides a potent platform for kin discrimination in Myxococcus xanthus.
