    Broad and direct interaction between TLR and Siglec families of pattern recognition receptors and its regulation by Neu1

    Guo-Yun Chen et al.
    Sialoside-based pattern recognition by Siglecs directly regulates toll-like receptor signaling and a sialidase inhibitor protects against endotoxemia.

    Siglec receptors impact mammalian lifespan by modulating oxidative stress

    Flavio Schwarz et al.
    By contributing to the maintenance of ROS homeostasis, CD33-related Siglecs control oxidative damage and influence rate of aging and lifespan.

    Siglec1-expressing subcapsular sinus macrophages provide soil for melanoma lymph node metastasis

    Rohit Singh, Beom K Choi
    When pioneer metastatic cells enter a sentinel lymph node through afferent lymphatics subcapsular sinus, macrophages provide them soil to proliferate and colonize lymph node.

    Tuberculosis-associated IFN-I induces Siglec-1 on tunneling nanotubes and favors HIV-1 spread in macrophages

    Maeva Dupont et al.
    Type-I interferon enriched microenvironment generated by Mycobacterium tuberculosis induces the Siglec-1 receptor expression in human macrophages, including on tunneling nanotubes, and contributes to the exacerbation of cell-to-cell transfer of HIV-1.

    Accelerated phosphatidylcholine turnover in macrophages promotes adipose tissue inflammation in obesity

    Kasparas Petkevicius et al.
    Obesity leads to increased phosphatidylcholine turnover in adipose tissue macrophages that makes them susceptible to saturated fatty acid-induced inflammation.

    The adhesion-GPCR BAI1 shapes dendritic arbors via Bcr-mediated RhoA activation causing late growth arrest

    Joseph G Duman et al.
    The adhesion-GPCR BAI1 shapes dendritic arbors in the hippocampus by associating with Bcr late in development and stimulating its RhoA-GEF activity, resulting in dendritic growth arrest.

    B cells suppress medullary granulopoiesis by an extracellular glycosylation-dependent mechanism

    Eric E Irons et al.
    B cells regulate production of neutrophils by a novel mechanism by releasing ST6Gal-1, an active sialyltransferase, that suppresses granulopoiesis.

    A virus-packageable CRISPR screen identifies host factors mediating interferon inhibition of HIV

    Molly OhAinle et al.
    Host restriction factors that block cross-species transmission also play a role in limiting the replication of highly-adapted HIV-1 in IFN-stimulated cells.

    Neonatal-derived IL-17 producing dermal γδ T cells are required to prevent spontaneous atopic dermatitis

    Nicholas A Spidale et al.
    Neonatal-origin dermal Tγδ17 cells are required to maintain normal keratinocytes and prevent spontaneous atopic dermatitis.

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

    Nona Farbehi et al.
    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.
