… During embryogenesis, besides the defects on dorsal closure seen on puc mutants, a
fraction of mutant embryos die with generalized Bsk activity (Ríos-Barrera and Riesgo-Escovar, …

Dorsal closure is an epithelial remodeling process taking place during Drosophila
embryogenesis. JNK signaling coordinates dorsal closure. We identify and characterize acal as a …

Tango1 enables ER-to-Golgi trafficking of large proteins. We show here that loss of Tango1,
in addition to disrupting protein secretion and ER/Golgi morphology, causes ER stress and …

Plasma membranes fulfil many physiological functions. In polarized cells, different
membrane compartments take on specialized roles, each being allocated correct amounts of …

Cells with subcellular lumens form some of the most miniature tubes in the tubular organs of
animals. These are often crucial components of the system, executing functions at remote …

… Therefore, it is likely that endosome-associated actin ahead of the tube is required to
coordinate subcellular tube and cell growth (Ríos-Barrera and Leptin, 2021 preprint). This model …

… Luis Daniel Ríos-Barrera … LD Ríos-Barrera was funded by the European Molecular
Biology Laboratory Interdisciplinary Postdoctoral Programme under Marie Curie Actions. …

One of the central questions of developmental biology has been how tissues define patterns
with fixed boundaries, as exemplified by the classical French flag model from Lewis Wolpert …

… , we use tracheal terminal cells of the Drosophila respiratory system, which uses actin to
coordinate their direction of migration with the formation of a subcellular tube (Ríos-Barrera and …

… In this article, we report a 35-year-old woman with MRH refractory to a combined scheme
of prednisone and methotrexate, both at high doses, and who received tocilizumab achieving …
