Furthermore, the number of cells expressing C5 and LTB4 G-protein coupled receptors is significantly increased in perilesional skin compared to healthy control skin supporting the view that selectively disrupting the recruitment of granulocytes into the skin by inhibiting both C5 and LTB4 may be key to treating pemphigoid diseases.

RAS is a G-protein that works as a switch, toggling between "on" and "off" when bound to guanosine nucleotides, GTP or GDP.
Its role is reflected in the dopamine binding and inhibiting the activity of adenylyl cyclase, an enzyme from the lyase group which is a part of the cyclic adenosine monophosphate (cAMP) signal pathway which, in addition to the phosphatidylinositol pathway, represents the way in which the G-protein coupled receptors transmit a signal.
G-protein coupled receptor mutation analysis was completed on native liver tissue obtained at transplant which identified one of the typical pathogenic variants (c.602G>A.p.R201H) in exon 8 of the GNAS1 (adenylate cyclase stimulatory G protein) gene that has been associated with the MAS phenotype (1, 2, 3).
