Description

Slides and a movie are provided for a class covering the integrin family members and the downstream signaling pathways they activate and are part of the course “Cell Signaling Systems: A Course for Graduate Students.” The lecture focuses on the capacity of integrins to serve as mechanotransducers, with particular emphasis on signaling mechanisms downstream of integrins.

The movie is the author's work and shows the interaction of NIH 3T3 fibroblasts with beads coated with the integrin-binding domain of fibronectin (FNIII 7-10), which illustrates the ligand-dependent association between integrins and treadmilling actin in the cytosol. Slide 10 is where this movie fits into the slides. Similar results have been published by Felsenfeld et al. [Nature 383, 438-440 (1996)].
