Manipulable object and human contact: preferences and modulation of emotional states in weaned piglets

This study examines how weaned piglets respond to manipulable objects and human contact, finding that human interaction reduces stress more effectively than objects.

Piglets vocally express the anticipation of (pseudo)-social contexts in their grunts

This study shows that piglets' grunts differ in time and spectral features when anticipating different social events, indicating emotional state during anticipation.

PARK7/DJ-1 promotes pyruvate dehydrogenase activity and maintains Treg homeostasis

This study shows PARK7/DJ-1 enhances PDH activity in Tregs by inhibiting PDHA phosphorylation, maintaining Treg homeostasis and reducing EAE severity.

Reconstitution of the equilibrium state of dynamic actin networks

This study investigates how actin network length is regulated by actin density, ADF/Cofilin concentration, and network width, revealing principles of dynamic equilibrium in actin networks.

Actin filaments regulate microtubule growth at the centrosome.

This study shows that actin filaments at the centrosome reduce microtubule growth through steric hindrance, and that cell adhesion and actin network density influence microtubule numbers.
