This week’s articles report that neural activity promotes localized miRNA-mediated translational silencing at synapses and that activation of B cells triggers an unusual form of autophagy in these cells.
NEUROSCIENCE
Intraneuronal control of protein expression
Sambandan et al. report that local synaptic stimulation promotes localized maturation of a precursor microRNA and reduces target protein synthesis.
IMMUNOLOGY
Change for good
Martinez-Martin et al. found that an unusual form of autophagy is triggered after immunological B cell activation and tunes B cell responses to viral infection.
