The dynamic flow of proteins to and from the plasma membrane and between organelles is crucial for cellular function, signaling, and development. We study the cellular functions and biophysical properties of ESCRT proteins to uncover the fundamental principles governing membrane remodeling in plants and other organisms. ESCRT proteins are essential for endosomal trafficking of plasma membrane molecules as well as many other crucial cellular events. However, we are still far from understanding how ESCRTs mediate membrane remodeling in the context of all their many cellular functions. Using live imaging, electron tomography, genetics, biochemistry, structural biology, and computational modeling, we analyze endosomal membrane vesiculation in several plant lineages and other organisms to understand the common principles that underlie ESCRT membrane bending. We also have uncovered novel functions of ESCRT proteins in cell plate maturation during cytokinesis, nuclear dynamics, and epidermal cell differentiation. These findings are helping us to elucidate basic mechanisms essential for cell function and plant development, with broader implications for cell biology and plant biotechnology.

Bienestar y evaluación del dolor en animales de experimentación
El bienestar animal es un concepto utilizado para caracterizar el estado físico y mental de un animal y cómo éste enfrenta las condiciones en las que vive. La American Veterinary Medical Association, indica para que haya bienestar animal se “requiere la prevención y el tratamiento de enfermedades y dolor, un cuidado responsable, un alojamiento adecuado, manejo, nutrición, trato humanitario y cuando sea necesario, la eutanasia humanitaria”.
