It shows that the rigid, crescent-shaped red blood cells don&rsquo;t cause these blockages on their own. It turns out that the disease produces four different types of red blood cells. The model shows that one of these &ndash; SS2, which is softer and deformable &ndash; triggers the problem by sticking to capillary walls. Only then do the rigid sickle-shaped cells block the vessels themselves.
