UCSD researchers create roadmap to integrin activation
...ys as interstate highways on a map, this study now enables us to see other back roads that lead to the destination," said Ginsberg. Talin is also critical for activation of related integrins, such as those on white blood cells. In these cells, activation of integrins is a critical step in the sticking and ...Newly discovered behavior in cancer cells signals dangerous metastasis
