Fig. 3From: The absence of dysferlin induces the expression of functional connexin-based hemichannels in human myotubesPresence of P2X7 receptor and TRPV2 channel in muscular biopsies from dysferlinopathy patients. The purinergic receptor P2X7 and the transient receptor potential vanilloid type 2 (TRPV2) channel were detected by immunofluorescence studies using specific antibodies in cross sections of human muscular biopsies from two dysferlinopathy patients and a control patient (patient without a muscular pathology). Nuclei were stained with DAPI (blue signal). Scale bar: 50 μmBack to article page
