A fascinating question relates to the nature of the molecular mechanisms which regulate ion channel targeting into distinct subdomains of the sarcolemma and their tethering in large molecular complexes. Cardiac myocytes are structurally and functionally highly polarized cells. While the transmission … Meer weergeven The function of the heart is governed by the electrical and mechanical activity of myocytes. The functional expression of several different types of ion channels in the myocyte … Meer weergeven The IKr current is encoded by the human ether-a-go-go–related gene (HERG, also known as KCNH2) in the heart (Sanguinetti … Meer weergeven Cardiomyocytes are exposed to mechanical forces when the heart contracts. These forces consist of stretch, shear and … Meer weergeven Cardiac excitability can be regulated by cellular lipid content. Free cholesterol is a major lipid class shown to regulate membrane fluidity, curvature, and stiffness (Lundbaek et al., 1996). The function of several … Meer weergeven WebRESEARCH INTEREST: Our research focuses on how subunits that are part of the cardiac voltage-gated sodium channel localize at the cell surface. NaV1.5 is the pore-forming α subunit, and its trafficking and activity are regulated by associated β subunits, as well as by other components of the channel; their proper localization is imperative for adequate ion … income tax amendments 2022
