ON THE COVER
Long-term nicotine exposure causes two neurotransmitter receptors to interact in the brain. Fang Li et al. generated a peptide inhibitor to prevent this receptor complex, allowing rats weaned off nicotine to reduce addiction relapse. Image shows a neuronal synapse with the peptide inhibitor (green) preventing the two neurotransmitter receptors (blue and red) from forming a complex.

Endogenous thymidine plays a critical role in the induction of replication stress in thymocytes.
Regulation of PTEN activity by p38δ-PKD1 signaling in neutrophils confers inflammatory responses in the lung
Deletion of p38 MAP kinase p38 d results in decreased alveolar neutrophil accumulation and attenuation of acute lung injury through activation of protein kinase D1 and PTEN.

Conditional deletion of cytokine receptor chains reveals that IL-7 and IL-15 specify CD8 cytotoxic lineage fate in the thymus
Two cytokines that signal through the common gamma chain receptor, IL-7 and IL-15, are responsible for the differentiation of developing thymocytes into CD8+ cytotoxic lineage T cells in mice.
Procontractile G protein–mediated signaling pathways antagonistically regulate smooth muscle differentiation in vascular remodeling
The G proteins Gα12/Gα13 and Gαq/Gα11 have opposing effects on vascular remodeling by differentially regulating vascular smooth muscle cell differentiation.
