    Light-induced engagement of microglia to focally remodel synapses in the adult brain

    Carla Cangalaya et al.
    The causal role of microglia in the acceleration of spine turnover and generation of presynaptic filopodia is directly demonstrated in the adult brain following acute focal synaptic photodamage.

    Stem cell niche exit in C. elegans via orientation and segregation of daughter cells by a cryptic cell outside the niche

    Kacy L Gordon et al.
    A previously undetected dynamic cell structure orients the mitotic spindle of germ stem cells and grows over one daughter cell, thus helping to balance niche retention with niche exit.

    Intra-species differences in population size shape life history and genome evolution

    David Willemsen et al.
    Population genetics in turquoise killifish wild populations reveals how small population size and genetic drift determine the accumulation of deleterious gene variants leading to short lifespan.

    Single-cell RNA-sequencing reveals distinct patterns of cell state heterogeneity in mouse models of breast cancer

    Syn Kok Yeo et al.
    The unraveling of distinct mammary tumor hierarchies in various mouse models of breast cancer emphasizes the need to account for specific cell states with potentially varying therapeutic vulnerabilities in tumors.

    Host sirtuin 2 as an immunotherapeutic target against tuberculosis

    Ashima Bhaskar et al.
    The inhibition of host Sirtuin-2 by AGK2 restricts mycobacterial growth in vivo by modulation of host transcriptome leading to activation of protective immune responses.

    Chronic ethanol consumption compromises neutrophil function in acute pulmonary Aspergillus fumigatus infection

    Nathalia Luisa Sousa de Oliveira Malacco et al.
    Cell biology analysis demonstrated for the first time the effect of chronic ethanol consumption in neutrophil impaired migration by CXCR2 downregulation and neutrophil function during acute Aspergillus fumigatus infection.
