Bidirectional transport by molecular motors
… problem is to transport cargos with a team of plus and a team of minus motors simultaneously, so that they can travel bidirectionally, as observed in cells. The presumably simplest mechanism for such bidirectional transport is provided by a 'tug-of-war' between the two motor teams which is …

Bidirectional cargo transport by microtubule-based molecular motors
… in vivo, indicating that the motors engage in a tug-of-war. When the complex hits a barrier, the cargo often reverses direction. In some cases, it tries several up-and-back motions, during which time the dynein likely pulls the cargo onto a different protofilament, and is sometimes able to bypass …

The interconnected roles of spastin and protrudin in endosomal sorting
… I investigated the functional interaction of spastin and protrudin and found that protrudin, an ER-associated adaptor molecule involved in anterograde membrane traffic, is a novel factor regulating endosomal tubule fission in non-polarised cells and in human iPSC-derived neurons. This …

Regulation Of Neutrophil Homeostasis By Chemokines Signaling Through The Cxcr2 And Cxcr4 Receptors
The number of neutrophils in the blood is tightly regulated to ensure adequate protection against microbial pathogens while minimizing damage to host tissue. Neutrophil homeostasis in the blood is achieved through a balance of neutrophil production, release from the bone marrow, and clearance from …
