Calcium-dependent regulation of auxin transport in plant development
The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).

Nanomaterial safety for microbially-colonized hosts: Microbiota-mediated physisorption interactions and particle-specific toxicity
The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

Spreading the Fire: Why is Pyroptotic Cell Death Contagious?
The word ¨pyroptosis¨ can be understood as ¨fiery falling¨, which describes the bursting of pro-inflammatory signals from the dying cell. Our observations indicate that pyroptosis also ¨spreads like wildfire¨ and once a cell dies via pyroptotic cell death, neighbouring cells are more prone to die as…

Discovery of a NAPE-PLD inhibitor that modulates emotional behavior in mice, Nat. Chem. Biol. 2020
N-acylethanolamines (NAEs), which include the endocannabinoid anandamide, represent an important family of signaling lipids in the brain. The lack of chemical probes that modulate NAE biosynthesis in living systems hamper the understanding of the biological role of these lipids.
