Ablation of Plasma Prekallikrein Decreases LDL Cholesterol by Stabilizing LDL Receptor and Protects against Atherosclerosis
Conclusions: PK regulates circulating cholesterol levels through binding to LDLR and inducing its lysosomal degradation. Ablation of PK stabilizes LDLR, decreases LDL cholesterol and prevents atherosclerotic plaque development. This study suggests that PK is a promising therapeutic target to treat ASCVD.PMID:35189703 | DOI:10.1161/CIRCULATIONAHA.121.056491

Recognizing Vaccine-Induced Immune Thrombotic Thrombocytopenia
CONCLUSIONS: Vaccine-induced immune thrombotic thrombocytopenia is a serious complication of vaccination that is not feasible to anticipate or prevent. When the patient presents with sustained headache, neurologic symptoms/signs, abdominal pain, dyspnea, or limb pain/swelling beginning 5–30 days post vaccination, platelet count and d-dimer must be measured, and imaging for thrombosis performed. Confirmation of vaccine-induced immune thrombotic thrombocytopenia diagnosis should be ordered (platelet factor 4/polyanion enzyme-linked immunosorbent assay; platelet factor 4–enhanced platelet activation testing) as treatm...

Canagliflozin Inhibits Human Endothelial Cell Proliferation and Tube Formation
In conclusion, the present study identified canagliflozin as a potent inhibitor of human EC proliferation. The anti-proliferative action of canagliflozin is observed in ECs isolated from both the venous and arterial circulation, and is partly due to the blockade of cyclin A expression. In addition, this study found that canagliflozin inhibits tube formation in cultured ECs and mouse aortic rings. Notably, these actions are specific for canagliflozin and not seen with other SGLT2 inhibitors. The ability of canagliflozin to exert these pleiotropic effects on EC function may contribute to both the adverse and salutary actions...

KLF11 (Kru üppel-Like Factor 11) Inhibits Arterial Thrombosis via Suppression of Tissue Factor in the Vascular Wall.
Conclusions- Our data demonstrate that KLF11 is a novel transcriptional suppressor of F3 in vascular smooth muscle cells, constituting a potential molecular target for inhibition of arterial thrombosis. PMID: 30602303 [PubMed - as supplied by publisher]

ADAMTS13 controls vascular remodeling by modifying VWF reactivity during stroke recovery
Angiogenic response is essential for ischemic brain repair. The von Willebrand factor (VWF)–cleaving protease disintegrin and metalloprotease with thrombospondin type I motif, member 13 (ADAMTS13) is required for endothelial tube formation in vitro, but there is currently no in vivo evidence supporting a function of ADAMTS13 in angiogenesis. Here we show that mice deficient in ADAMTS13 exhibited reduced neovascularization, brain capillary perfusion, pericyte and smooth muscle cell coverage on microvessels, expression of the tight junction and basement membrane proteins, and accelerated blood-brain barrier (BBB) break...
