Rho-kinase (ROCK) is a critical mediator of both biomechanical (tissue stiffness) and biochemical (TGF-b mediated) pathways involved in the dysregulated activation of myofibroblasts, the cells thought to underlie the pathogeneisis of fibrotic disease. Aberrant expression and activation of ROCK results in sustained presence of activated myofibroblasts and excessive extracelluar matrix production, leading to tissue fibrosis. ROCK exists as two highly related isoforms, ROCK1 and ROCK2. Lycera is currently progressing potent, highly-specific inhibitors of the ROCK2 isoform, which has recently been demonstrated to inhibit the production of pathogenic cytokine IL-17 in immune cells. Lycera’s ROCK inhibitors are currently being investigated in pre-clinical models of fibrosis.
