Connexin 37 and Connexin 40 (Cx37, Cx40) are the major gap junction proteins expressed in vascular endothelial cells[85-89]. These proteins are very dynamic, exhibiting rapid turnover times and variable expression patterns. Although the extent of combinations of different connexins within connexons and channels remains unclear, immunohistochemical and immunocytochemical studies demonstrate differential expression and localization patterns of both vascular connexins in endothelium, depending on species[97], vascular bed[98-100], and local hemodynamics[101].[...] For the microcirculation in vivo studies implicate Cx40 as the constitutive vascular gap junction protein across species [and vascular bed, playing an important role in coupling between cells in the vascular wall[78, 97-98], particularly in response to changes in tissue metabolic demand.]

Connexin 37, 40, and 43 (Cx37, Cx40, Cx43, respectively) are the major gap junction proteins expressed in vascular endothelial cells (7, 32, 34, 39, 45). These proteins are very dynamic, exhibiting rapid turnover times and variable expression patterns. [...]

Although the extent of combinations of different connexins within connexons and channels remains unclear, immunohistochemical and immunocytochemical studies demonstrate differential expression and localization patterns of all three vascular connexins in endothelium, depending on species (44), vascular bed (25, 37, 53), and local hemodynamics (21). In vivo studies implicate Cx40 as the constitutive vascular gap junction protein across species and vascular bed, playing an important role in coupling between cells in the vascular wall (44).
