Sudo et al. demonstrate that group 2 innate lymphoid cells (ILC2s) in the bone marrow become activated following chemotherapy-induced stress and support hematopoietic recovery by producing GM-CSF. Adoptive transfer of ILC2s has therapeutic potential for myelosuppressive conditions.

Thouvenel et al. isolate BCR sequences from Plasmodium-specific IgM+ human memory B cells, expressing them as both IgM and IgG molecules. Multimerization confers superior antigen binding and parasite restriction, highlighting an important role for memory B cell–derived IgM in immunity.

Systematic analysis of the neuronal receptor interactome in multiple sclerosis brains reveals the metabotropic glutamate receptor 8 as a disbalanced hub. Its activation constitutes a novel treatment strategy to enhance neuronal resilience by inhibiting pathological calcium overload in inflammation-induced neurodegeneration.

The role of IgM in human malaria is unclear. In a cohort study in Mali, Hopp et al. find that malaria-specific memory B cells are disproportionally IgM in children, are activated during acute malaria, and produce IgM that inhibits malaria parasite growth.

Starobova et al. demonstrate that vincristine-induced peripheral neuropathy (VIPN) is driven by activation of the NLRP3 inflammasome and release of IL-1β. Moreover, inhibition of NLRP3-mediated IL-1β release prevents VIPN in a murine model without affecting chemotherapy efficacy.

Using single-cell RNA sequencing and TCR sequencing, Pauken et al. detect CD8+ T cell clones shared between blood and tumor in mice or melanoma patients, characterize matching clones in blood and tumor, and identify potential biomarkers for their isolation in blood.
Brief Definitive Report

Combining transcriptomic and TCRαβ repertoire analysis of circulating and tumor-infiltrating CD8 T cells from patients with metastatic melanoma, Lucca et al. identify a blood-based population with effector properties that reflect those of clonally related tumor-resident T cells.

Viewpoint
Emanuele Andreano, Rino Rappuoli
Rappuoli and Andreano highlight that, in humans, neutralizing antibodies deriving from germlines IGHV3-53/IGHV3-66 dominate the immune response to SARS-CoV-2 infection and discuss potential correlations with self-reacting antibodies in COVID-19.

A significant number of patients respond poorly to current asthma interventions. Balestrini et al. advance the concept that sensory nerves control inflammation in asthma, demonstrating that a novel inhibitor of TRPA1, a chemical irritant receptor, suppresses asthmatic inflammation in several preclinical species.
Insights | JEM 125th Anniversary
Falk Nimmerjahn, Jeffrey V. Ravetch
In concomitance with the JEM 125th anniversary celebration, Jeffrey Ravetch and Falk Nimmerjahn discuss the identification of subclasses within the immunoglobulin G (IgG) isotype by Grey and Kunkel in 1964 and the relevance of these findings for the study of antibody-mediated immune responses.
