Immune-related adverse events and the balancing act of immunotherapy
The benefit from immune checkpoint inhibitors is tempered by immunologic toxicities, which involve diverse organs, have varying biology, onset time, and severity. Herein, we identify important areas of controversy and open research questions in the field of immune-related toxicity.

Systematic analysis of drug-associated myocarditis reported in the World Health Organization pharmacovigilance database
Multiple drugs have been in the past associated with myocarditis. Here the authors perform a pharmacovigilance study and analyze 5108 reports of drug-induced myocarditis reporting temporal trends and overall mortality and identifying emerging drug classes among the treatments associated with myocarditis.

Post-surgical adhesions are triggered by calcium-dependent membrane bridges between mesothelial surfaces
Surgical adhesions are organ-joining bands of scar tissue that remain clinically untreatable. Here, the authors show that adhesions are formed through expansive mesothelial membrane bridges, and that blocking these with small molecules prevents formation of adhesions in mice.

Endogenous opioids contribute to insensitivity to pain in humans and mice lacking sodium channel Nav1.7
Nav1.7 channels are known to regulate pain perception in humans and mice. Here, the authors provide evidence that Nav1.7 deletion leads to transcriptional upregulation of opioid peptides in sensory neurons, and that treatment with the opioid blocker naloxone helps reverse analgesia in mice and human Nav1.7 nulls.

Antibiotics in neonatal life increase murine susceptibility to experimental psoriasis
Commensal microbes are necessary for proper development of the immune system. Here Zanvit et al. show that neonatal antibiotics treatment causes long-term changes in the gut and skin microbiomes, and exacerbates immune-mediated skin pathology at adult age in mouse experimental models of psoriasis.

Pharmacogenomic and clinical data link non-pharmacokinetic metabolic dysregulation to drug side effect pathogenesis
Adverse drug reactions are an important clinical problem. Here the authors combine information about drug-induced gene expression changes and genetic variability of patients with a genome-scale metabolic model to identify drug-induced changes in cellular metabolism that may be linked to drug side effects.

Ionizing irradiation induces acute haematopoietic syndrome and gastrointestinal syndrome independently in mice
Ionizing radiation damages the gastrointestinal system, but the cell types involved in intestinal damage and repair are controversial. Here the authors use bone marrow transplantation models and various irradiation regimes to rule out a role of bone marrow-derived cells in acute gastrointestinal injury and recovery in mice.

Loss of TRPM2 function protects against irradiation-induced salivary gland dysfunction
A debilitating side effect of radiotherapy in patients with head and neck cancers is xerostomia as a result of salivary gland dysfunction. Here Liu et al. show that activation of the calcium channel TRPM2 in salivary gland cells contributes to irradiation-induced loss of salivary fluid secretion.
