Dr. Strickland's laboratory was one of two laboratories to identify the LDL receptor related protein (LRP1) as an hepatic receptor involved in the removal of protease-inhibitor complexes (a2M-protease or serpin-protease). While identifying LRP1, the Strickland laboratory also discovered the 39 kDa Receptor Associated Protein (RAP), a molecular chaperone for this receptor family. We now know that LRP1 is an efficient endocytic and signaling receptor that is widely expressed in the vasculature, in neurons and in inflammatory cells such as macrophages. Ongoing projects in the Strickland laboratory include investigating the role of LRP1 in regulating thrombosis, cell migration, proliferation and signaling events, ultimately altering the pathology of certain diseases such as vascular remodeling, atherosclerosis, and vessel wall pathology.

Grants and Contracts

R01 HL114379-01
Role of lipoprotein receptors in venous thrombosis
The major goals of this project are to test the hypotheses 1) that the LDLr modulates thrombus resolution during DVT by modulating inflammation; 2) that LRP1 modulate thrombus resolution by regulating protease levels and by regulating signaling events in inflammation and 3) that we can engineer inhibitor molecules for receptor blockade that would enhance thrombus resolution in DVT.

R01 HL1120388
Mechanism by which LRP1 protects the vasculature
The objectives of this grant are to test the hypothesis LRP1 maintains the integrity of the vessel wall by:  1) modulating protease activity which prevents elastin degradation and 2) by regulating the non-cannonical TGFb signaling pathway thereby affecting SMC physiology.  Further, the hypothesis that rare LRP1 variants contribute to aneurysm formation in humans will be tested.

Marfan Foundation
Role of LRP1 in Marfan's syndrome
The objectives of this grant are to test the hypothesis that that LRP1 cross-talks with angiotensin II type 1 receptor (AT1r) to modulate signaling pathways that are key for extracellular matrix development and homeostasis in the vasculature.  

T32 HL007698-18
Interdisciplinary Training Program in Cardiovascular Disease
The objectives of this training program are to provide training for five predoctoral and five postdoctoral trainees in basic and translational sciences as they apply to cardiovascular medicine.
