Research Activities

The Cardeza Center pursues a broad range of basic research that can be divided into three focus areas: basic research, clinical/translational and core laboratories.  We also host a seminar series during the academic year.

Title: GRK5 regulation of GPCR signaling in platelets

The proposed studies will 1) provide the first insight into how GRK5 regulates GPCR signaling and how GRK5 itself can be regulated in platelets, and 2) lay the groundwork for optimizing antiplatelet therapy for the nearly 2% of the US population who are homozygous for the high-risk GRK5 G-allele.

Title: Short inhibitory RNAs in platelet and megakaryocyte function.

We have established for the first time a highly novel system of non-integrative, temporally controlled, tunable gene therapeutic reprogramming of blood platelets and their parent cells, megakaryocytes, by targeted suppression of protein translation from individual mRNAs in vivo, which we have found is naturally selective for the megakaryocyte / platelet lineage without affecting other cell types. This proposal aims both to exploit, and to study, this tissue-selective gene therapeutic approach. The studies in this proposal will employ this cutting edge approach to elucidate the cellular and physiological roles and underlying mechanisms of several related pathways highly relevant to platelet physiology and disease, and to study the unique properties of platelets and megakaryocytes that support this tissue-specific gene therapeutic reprogramming.

Title: Integration of platelets and coagulation to maintain hemostasis in vivo

09/05/2025-03/31/2029

The coagulation system and platelets work together as part of the normal response to vascular injury, called hemostasis, producing a plug that limits blood loss. Disruption of the hemostatic system in pathologic settings can result in many clinical problems, including excessive bleeding (e.g. hemophilia). The goal of this project is to better understand how coagulation and platelets interact to produce an optimal response to injury, and translate that understanding into improved methods to treat disorders of the hemostatic system.

Title: Platelets as regulator of non-neurological complications of ischemic stroke

06/15/2025-03/31/2029

Every 40 seconds, someone in the U.S. suffers a stroke; but the damage caused by strokes is not just limited to the brain since pneumonia is the most frequent cause of death in stroke patients during post-acute recovery. In spite of evidence that the gut becomes leaky and allows for bacteria to translocate after stroke, treatments such as prophylactic antibiotic use have not decreased mortality in stroke victims. Therefore, in this proposal we aim to gain a deeper understanding of the pathogenesis of remote organ injury and infection after stroke to help identify new targets to decrease the burden of strokes.

Title: Hypoxemia With Sleep In Sickle Cell Anemia-Prevalence, Clinical And Cellular Impact, And Response To Therapy: A Multi-Site Proposal Using Novel Collaborative Pathways 

09/1/25-6/30/2029

This multi-site study investigates how overnight oxygen drops during sleep accelerate red blood cell sickling, cellular inflammation, and cognitive decline in patients with sickle cell disease. By tracking patients across collaborative medical centers, researchers aim to determine how targeted nighttime oxygen therapies can prevent organ damage and improve overall health outcomes.
