Immune vascular interactions in lupus

Systemic lupus erythematosus (SLE) is a medical condition in which the immune system attacks healthy cells and tissues in the body. It affects approximately 1.5 million people in the United States, with women of color being 2-3 times more likely to develop and die from SLE than other groups. One complication of SLE is vasculitis, inflammation of the blood vessels, which progresses more rapidly due to interactions between the immune system and blood vessel lining.  Detecting vasculitis in the early stages can be challenging because the symptoms are often subtle and nonspecific. To improve early detection, we are using biomaterial models to study how immune cells interact with blood vessels in SLE patients. By studying these interactions, we hope to identify new ways to detect and treat vasculitis in its early stages. Because SLE is a health disparity, we are also studying how a patient's background, such as their race and ethnicity, can influence their immune cell function and the development of vascular inflammation. By better understanding these factors, we hope to develop more targeted and effective models for SLE and its complications.

Reviving Macrophages for Effective Tissue Regeneration in Aging - Insights from Biomaterial Models

Over 700 million people worldwide are 65 years or older, and as we age, our ability to heal decreases. Macrophages, immune cells that play a crucial role in tissue regeneration, also become less effective with age. To better understand this process, we are designing a biomaterial model system to investigate how the age of macrophages affects macrophages' ability to support tissue healing. We are also interested in using our model system to explore potential therapeutic interventions that can improve macrophage function. By focusing on tissue regeneration in aging, we hope to gain insights into how macrophages change over time and identify ways to rescue their function using targeted therapies.  Our work will shed light on this critical aspect of the aging process and pave the way for more effective treatments in the future.

Overlooking Ancestry in Regenerative Medicine - Addressing Health Inequities through Biomaterial Models

Everyone's health is influenced by their background, both genetics and lived experiences. However, most regenerative medicine research focuses on people of European descent, which overlooks the impact of ancestry on disease development and wound healing. To fill this gap, we use biomaterial models to understand how ancestry affects innate immune cellular responses in wound healing. By studying these interactions, we aim to identify wound healing risks and outcomes for people from systemically excluded backgrounds. Our research introduces a new perspective on health inequities, bringing attention to the systemic exclusion of oppressed and excluded communities in biomedical science. Ultimately, we hope to use our findings to develop more personalized and effective treatments for all individuals.

Decoding the Signals - How the Extracellular Matrix Directs Macrophage Behavior for Tissue Regeneration

Macrophage immune cells play a vital role in tissue homeostasis, wound healing, and tissue regeneration, but we still have much to learn about how they function. Specifically, we are interested in understanding how the extracellular matrix (ECM) influences macrophage behavior. To do this, we design biomaterial tools to study how different ECM components, known as ECM ligands, direct macrophage function. By investigating how the composition of the ECM affects macrophage activation and homeostasis, we hope to better understand the signals that control tissue regeneration. Ultimately, our work could lead to new strategies for promoting tissue repair and healing.
