APLAID is a rare autoinflammatory disorder driven by mutations in PLCG2. Here the authors provide a new mouse model using the human APLAID p.Ser707Tyr mutation. The mouse recapitulates clinical features of APLAID that can be prevented by anti-G-CSF. Individuals with APLAID were also shown to have high circulating levels of G-CSF suggesting this might be a suitable target for the clinic.

NLRP10 has been considered as an inflammasome inhibitor. Here the authors show that upon mitochondrial rupture, NLRP10 assembles a canonical inflammasome and is highly expressed in differentiated keratinocytes, possibly supporting skin homeostasis.

NK cells require an immunological synapse to kill cancer cells and these synapses have been shown to have membranous protrusions. Here the authors use cutting-edge imaging and other techniques to show that tumor serine metabolism results in a reduction in NK cell sphingomyelin content and a lack of these membranous protrusions, which could contribute to a failure to kill cancer cells.

Singer and colleagues show that the developmental fate of autoreactive CD4⁺ thymocytes is determined by the timing and duration of agonist signaling. Early agonist signaling induces clonal deletion, whereas late agonist signaling induces differentiation into Foxp3⁺ T_reg cells or IL-2⁺ T_eff cells depending on whether TGF-β disrupts TCR signaling.

The authors show that Nlrp10 can form a functional inflammasome in vitro and ex vivo, and that this inflammasome is protective in dextran sodium sulfate-induced colitis in mice.

Kamiya and colleagues examine the effects of chronic social-defeat stress on the intestinal microbiome and show a pathological role played by dectin-1 and interleukin-17 expressed by gut γδ T cells on this behavioral vulnerability.
