How the protein ATP1B3 affects T cells in autoimmunity

ATP1B3: novel regulator of T cell-mediated immunity

NIH-funded research New York University School of Medicine · NIH-11170769

This project looks at whether the protein ATP1B3 helps control T cell activity that drives autoimmune diseases and could point to new drug targets for people with autoimmune conditions.

What this research studies

If you have an autoimmune condition, this research is exploring a protein called ATP1B3 that may change how T cells behave. Researchers used genetic screens to find ion channel and transporter genes that influence T cell responses and are now focusing on components of the sodium-potassium pump. The work will involve lab studies of T cells and related experiments to see how altering ATP1B3 changes immune signals that can cause autoimmunity. Findings could guide future efforts to develop medicines that calm harmful T cell activity.

Who could benefit from this research

Good fit: People with autoimmune diseases who are interested in contributing blood or tissue samples or who might join future clinical trials focused on T cell-targeting therapies would be most relevant.

Not a fit: People without autoimmune conditions or whose illness is driven by non–T-cell mechanisms are unlikely to receive direct benefit from this early laboratory-focused work.

Why it matters

Potential benefit: If successful, the work could identify a new drug target that helps reduce harmful T cell activity in autoimmune diseases.

How similar studies have performed: Ion channels are established drug targets in other fields, but applying channel-targeting to autoimmune diseases is relatively new and this project builds on early genetic screens pointing to ATP1B3.
