    SMARCAL1 Is a Dual Regulator of Innate Immune Signaling and PD-L1 Expression That Promotes Tumor Immune Evasion

    The authors identified the SNF2-family DNA translocase SMARCAL1 as a factor that favored tumor immune evasion by a dual mechanism involving both the suppression of innate immune signaling and the induction of PD-L1-mediated immune checkpoint responses.

    Id2 Epigenetically Controls CD8+ T Cell Exhaustion by Disrupting the Assembly of the Tcf3-LSD1 Complex

    Researchers found that inhibitor of DNA binding protein 2 (Id2) transcriptionally and epigenetically regulated the generation of Slamf6+ progenitor exhausted T cells and their conversion to Tim-3+ terminally exhausted cells.

    Tumor-Retained Activated CCR7+ Dendritic Cells Are Heterogeneous and Regulate Local Anti-Tumor Cytolytic Activity

    Scientists used photoconvertible mice to precisely track dendritic cell (DC) migration.They reported that CCR7+ DCs were the dominant DC population that migrated to the draining lymph node.

    Kidins220 Regulates the Development of B Cells Bearing the λ Light Chain

    In vivo ablation of Kidins220 in B cells resulted in a marked reduction of λ light chain-expressing B cells, and Kidins220 knockout B cells failed to open and recombine the genes of the Igl locus, even in genetic scenarios where the Igk genes could not be rearranged or where the κLC conferred autoreactivity.

    Essential Role of CD155 Glycosylation in Functional Binding to DNAM-1 on Natural Killer Cells

    Scientists showed that the N-linked glycosylation at residue 105 in the first immunoglobulin-like domain of CD155 was involved in the binding of CD155 to both DNAM-1 and tyrosine-based inhibitory motif domain.

    The Deubiquitylase Otub1 Regulates the Chemotactic Response of Splenic B Cells by Modulating the Stability of the γ-Subunit Gng2

    Researchers showed that loss of one of the most highly expressed deubiquitylating enzymes, Otub1, resulted in changes in murine splenic B cell subsets, leading to a significant increase in marginal zone and transitional B cells and a concomitant decrease in follicular B cells.
