Annexin A5 therapy attenuates vascular inflammation and remodeling and improves endothelial function in mice.

Objective: Annexin A5 (AnxA5) has antithrombotic, antiapoptotic, and antiinflammatory properties; we investigated its effectiveness against vascular inflammation, remodeling, and dysfunction in accelerated atherosclerosis.

Methods And Results: AnxA5 (1 mg/kg per day or vehicle) was investigated in vascular injury models in hypercholesterolemic apolipoprotein E (ApoE)3*Leiden mice. AnxA5 treatment reduced adhesion and infiltration of leukocytes by 71% to 69% (P=0.

Defining an N-terminal activation domain of the orphan nuclear receptor Nurr1.

Nurr1 is an orphan nuclear receptor essential for the development of midbrain dopaminergic neurons. Activation of Nurr1 depends on two so-called activation functions (AFs) situated in the N- and C-terminal regions, respectively. The region important for activation within the C-terminal domain has been shown to promote activation in a highly cell-type specific fashion in the absence of added exogenous ligands.
