Aggregation of platelets, as indicated by CD41 IHC, was low in all groups and significantly decreased in cases of DENs and AD lesions compared to both their corresponding endometrium (* p = 0.028; **** p < 0.0001) and healthy controls (** p = 0.001; **** p < 0.0001) (Figure 1 and Figure 2a). This evidence concerns the gene ITGA2B and Alzheimer disease.
