Further evidence of proinflammatory and profibrotic responses in late‐stage DMD muscle was indicated by IPA‐identified activation of the ‘phagosome formation’ CP and several upstream regulators, notably TGFβ1, IFNα/γ and TNF group (Figures 2a and 3). The gene discussed is TGFB1; the disease is Duchenne muscular dystrophy.
