Expression of GLP‐1R in muscle fibres in PM and CIM. (A, B) representative images of muscle specimens of PM patients (n = 9) of (A) inflammatory and (B) non‐inflammatory area. Haematoxylin & Eosin (HE) and immunofluorescence staining against GLP‐1R (green). Nuclei were counterstained with DAPI (blue) and merged images of GLP‐1R, DAPI, and phase contrast were shown. Arrow indicates the dying muscle fibre. Scale bar indicates 20 μm. (C, D) representative images of muscle specimens of CIM of (C) inflammatory and (D) non‐inflammatory area. HE and immunofluorescence staining against GLP‐1R (green). Nuclei were counterstained with DAPI (blue) and merged images of GLP‐1R, DAPI, and phase contrast were shown. Scale bar indicates 20 μm.
