Pericytes (zie mijn vorige post voor link met CD147 receptor) geven volgens mij extreem belangrijke hints voor het succes van Ivermectine. Bloeddruk, doorstroming, weefselregeneratie, ogen, BBB, rol in apoptose etc. etc. etc
Hier de (voor mij) meest in het oog springende info van de wiki pagina:

Angiogenesis and the survival of endothelial cells
Pericytes are also associated with endothelial cell differentiation and multiplication, angiogenesis, survival of apoptotic signals and travel. Certain pericytes, known as microvascular pericytes, develop around the walls of capillaries and help to serve this function.
Blood flow
Increasing evidence suggests that pericytes can regulate blood flow at the capillary level. For the retina, movies have been published[18] showing that pericytes constrict capillaries when their membrane potential is altered to cause calcium influx, and in the brain it has been reported that neuronal activity increases local blood flow by inducing pericytes to dilate capillaries before upstream arteriole dilation occurs.[19]
Blood–brain barrier
Pericytes play a crucial role in the formation and functionality of the blood–brain barrier. This barrier is composed of endothelial cells and ensures the protection and functionality of the brain and central nervous system. It has been found that pericytes are crucial to the postnatal formation of this barrier. Pericytes are responsible for tight junction formation and vesicle trafficking amongst endothelial cells. Furthermore, they allow the formation of the blood–brain barrier by inhibiting the effects of CNS immune cells (which can damage the formation of the barrier) and by reducing the expression of molecules that increase vascular permeability.[16]
