| Open AccessVascular endothelial-derived SPARCL1 exacerbates viral pneumonia through pro-inflammatory macrophage activation
The molecular basis underlying infection infection-mediated lung pathology is not fully revealed. Here the authors report that SPARCL1 expressed in pulmonary capillary endothelial cells contributes to immune pathology in mouse model via pro-inflammatory macrophage induction, while circulating SPARCL1 levels corelate with COVID-19 lethality.

| Open AccessPreserving ester-linked modifications reveals glutamate and aspartate mono-ADP-ribosylation by PARP1 and its reversal by PARG
Ester-linked modifications are common but difficult to detect. Here, the authors present methods based on ester preservation and a sensitive antibody to reveal DNA damage-induced mono-ADP-ribosylation on aspartate and glutamate. This signal, part of the first wave of PARP1 signaling, is removed by PARG.

| Open AccessMapping recurrent mosaic copy number variation in human neurons
Single cell genome sequencing approaches have identified somatic copy number variants (CNVs) in human neurons, but small sample sizes (<100 neurons) have limited the power to find recurrent patterns such as CNV hotspots in a single individual. Here, the authors develop an approach to map CNVs in 2097 neurons from a neurotypical individual, finding that >10% neurons contain at least one somatic CNV, and enabling deeper investigation of these events.
