    Identification of connexins in human oral mucosa and therapeutic effect of irsogladine maleate on aphthous stomatitis

    We identified connexins 26 and 32 in human oral mucosa. The presence of the connexins indicates the presence of gap junctions in this tissue. However, immunofluorescence study found no significant differences...
