Figure Lengend Snippet: Hypoproteinemia was found to promote platelet activation. (A–E) Wash platelet aggregation in WT, ADR and ADR Albumin mice induced by thrombin (A) , U46619 (B) , PAR4-AP (C) , collagen (D) and ADP (E) (n = 5 independent experimental animals). (F–H) Thrombin (F) , U46619 (G) and PAR4-AP (H) induced integrin αIIbβ3 activation in washed platelets from mice (n = 5 independent experimental animals). (I–K) Thrombin (I) , U46619 (J) and PAR4-AP (K) induced P-selectin release from washed platelets from mice (n = 5 independent experimental animals). (L–O) ATP release from washed platelets in mice was induced by thrombin (L) , U46619 (M) , PAR4-AP (N) and collagen (O) (n = 5 independent experimental animals). (P–R) Wash platelet spreading in mice induced by U46619 (P) , mean spreading area of individual platelets (Q) , and proportion of spreading platelets to total platelets in the field of view (R) (n = 3 independent experimental animals). Differences between groups were assessed by one-way ANOVA followed by Dunnett’s post hoc test. Statistics are presented as mean ± SEM. * P < 0.05, ** P < 0.01 and *** P < 0.001.
