TGFbeta activation OBSOLETE. The release of transforming growth factor beta (TGF-beta) from its latent state. TGF-beta is secreted as part of a large latent complex (LLC) that is targeted to the extracellular matrix. Release of TGFbeta from its latent state is required for TGFbeta to bind to its receptors, and can occur by a variety of mechanisms. TGF-B activation TGFB activation
