Immunology

We’re an emerging leader in immunology, poised to transform medicine by rebalancing the immune responses that cause systemic, chronic diseases.

Our Immunology Pipeline

Our teams use real-world, molecular, and clinical data to advance precision medicine, and investigate:

  • pathways common to systemic diseases like asthma and atopic dermatitis
  • peripheral inflammatory diseases like rheumatoid arthritis
  • autoimmune challenges in type 1 diabetes and cancer

T helper cell and interleukin molecules

Taking Down Type 2 Inflammatory Disease

We’re working to tame over-active immune responses that drive systemic, chronic diseases.

Type 2 Inflammation

Our goal: to give people their lives back by calming excessive inflammation–without compromising their ability to fight infection.

With our partner Regeneron, we study how blocking two interleukins1 can help calm type 2 inflammation, a driver of atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, and other conditions.

Beyond Type 2 Inflammation

Precision Immunology

Single-cell genomics, genetics, and proteomics help us understand exactly what makes patients different from one another.

Checkpoint Immunology

How can we restore the delicate balance between a protective immune response and destructive autoimmunity?2
 

Complement System

Can we stop a cascade of inflammation without compromising immunity, by blocking one protein?3
