Inflammation of the heart muscle, also known as myocarditis, can be caused by various viral infections. Parvovirus B19, known for inducing rashes in children and infants, has recently drawn attention as a potential risk factor for myocarditis in infants. In this research letter, researchers study and report cases of myocarditis in preschool students caused by parvovirus B19 infections. The letter aims to shed light on the detrimental effect of the disease to increase awareness.

Macronucleophagy helps control micronucleophagy to protect yeast cells during stress. Through extensive experiments with yeast mutants, researchers from Science Tokyo found that disrupting macronucleophagy triggers excessive micronucleophagy, causing cell death. They further identified that this hyperactivation is driven by the accumulation of Nuclear vacuolar junction (Nvj1), a key nuclear membrane protein. These findings shed light on the links between different autophagy pathways under challenging conditions, which are crucial to maintain cell health.
