Dr. Susan R. Weiss's lab at the University of Pennsylvania focuses on understanding how different types of coronaviruses interact with the human immune system. They study how these viruses, like SARS-CoV-2 and MERS, evade immune responses and lead to varying disease severities. The lab also examines the nasal epithelial cells, the first line of defense against these infections, to find ways to improve treatments and prepare for future outbreaks.

Dr. Hao Wu's lab at the University of Pennsylvania focuses on how genetic variations impact gene regulatory networks and influence cellular behavior. By using advanced techniques like single-cell multi-omics and machine learning, the lab aims to uncover the complex relationships between genomic variants and gene expression across different cell types. This research is particularly important for understanding human diseases and developmental processes, ultimately paving the way for new therapeutic approaches.

Dr. Xiaowei Xu's lab focuses on developing innovative therapies using advanced immunological approaches to combat melanoma, a serious skin cancer. The lab utilizes humanized mouse models to study immune responses and explore the potential of engineered immune cells and extracellular vesicles in targeted cancer therapies. Their research aims to make significant advancements in the effectiveness of existing cancer treatments while minimizing side effects.

Dr. Hong Xu's lab at the University of Pennsylvania focuses on understanding tauopathies, which are neurodegenerative diseases associated with the abnormal accumulation of tau proteins in the brain. The lab investigates how a protein called ASAP1 influences the spreading of tau pathology, potentially leading to better treatments for conditions like Alzheimer's disease. By studying how tau spreads and its interaction with cellular pathways, the lab aims to identify new therapeutic targets for these devastating diseases.

Dr. Xiaolu Yang's lab at the University of Pennsylvania focuses on understanding how specific proteins affect the development and progression of neurodegenerative diseases like ALS and FTD. They investigate the roles of unique proteins involved in maintaining the stability and function of other proteins in the cell, particularly regarding protein aggregation, which is a key feature in many diseases. Their research aims to explore potential therapeutic strategies to combat these conditions by enhancing our understanding of protein quality control mechanisms in cells.

Dr. Yeong Shin Yim's lab at the University of Pennsylvania focuses on how maternal immune responses during pregnancy affect brain development, specifically looking at differences between males and females. Their research investigates a specific signaling pathway (CXCR7/CXCL12) that is linked to neurodevelopmental disorders like autism and schizophrenia. By understanding these differences, the lab aims to uncover new ways to address and potentially prevent issues related to brain development that are influenced by maternal health.
