Choi (Jaehyuk) Lab

Pioneering therapies for immune-related diseases.

About Us

The goal of the Choi Lab at UT Southwestern to develop novel therapies for immune-related diseases by engineering novel solutions. To accomplish this, we first utilize high-dimensional approaches on human disease to identify targetable disease-promoting molecular defects. Second, we utilize engineering approaches to reverse these molecular changes.

The goal is to translate these findings to first-in-human clinical trials.

Scientists say they have identified a root cause of lupus - one that could pave the way for new treatments

An imbalance of T cells, which play a key role in the body’s immune response, could explain most cases of the disease, according to new research.

Stealing Strategies from Cancerous T Cells May Boost Immunotherapy

For some people with blood cancers like leukemia and lymphoma, CAR T-cell therapies have proven to be a transformative treatment. But for solid tumors like breast, colorectal, or pancreatic cancer, which make up about 90% of cancer cases, success with T-cell therapies has been harder to come by.

In vitro and in vivo screening identifies T cell mutations that reprogram CAR signalling and functional outputs.

Naturally occurring T cell mutations enhance engineered T cell therapies

T cell therapies have revolutionized cancer therapy for haematological cancers but have not yet been consistently effective in solid tumours, which represent 90% of adult cancers3. In both solid tumours and treatment-resistant haematological malignancies, they are limited by a combination of factors, including poor in vivo persistence, immunosuppressive environmental factors and T cell exhaustion4.
