Immune feedback receptor–ligand biology

We study how negative-feedback receptor–ligand pathways maintain immune balance, how these circuits are rewired in disease, and how they can be engineered into more precise immunotherapies.

3D immune feedback biology in disease tissue
T

T-cell checkpoint biology

We dissect PD-1 and LAG-3 receptor organization, ligand-dependent suppression, and proximity to the TCR, and use these principles to engineer selective T-cell modulation.

Scientific vision

Immune feedback receptor–ligand biology

Our central idea is that effective immunotherapy depends on understanding feedback circuits in context: where they operate, when they are induced, which cells they connect, and how strongly they regulate immunity.

By decoding and engineering these pathways, we aim to achieve more precise immune modulation while preserving protective immunity.

Jun Wang, PhD

Associate Professor, NYU Grossman School of Medicine
Member, Laura and Isaac Perlmutter Cancer Center

Jun Wang's research has focused on cancer immunotherapy and immune regulation for two decades. His early work investigated 4-1BB (CD137) immunotherapy and mechanisms of immune-related liver toxicity, including myeloid-associated pathways that could mitigate toxicity while preserving antitumor immunity. His subsequent work contributed to the discovery of Siglec-15 as an immune checkpoint, FGL1 as a functional ligand for LAG-3, mechanisms of PD-1 and LAG-3 regulation, a membrane inhibitory axis controlling MHC-I antigen presentation, and FGL1/TACI-mediated B-cell regulation.

The lab integrates fundamental receptor–ligand discovery, mechanistic immunology, protein engineering, and translational development to create new immunotherapies for cancer and autoimmune diseases.
