How GATA2, TGF‑β1, and TAL1 work together to build healthy natural killer (NK) cells
GATA2-TGF beta-TAL1 pathway as a critical mediator of NK Cell development
This project looks at how three key genes control NK cell development to help people with immune problems caused by GATA2 mutations.

What this research studies
From a patient perspective, researchers will compare NK cells from people with GATA2 mutations to NK cells from healthy donors to see which genes are turned on or off. They will use single‑cell RNA sequencing and molecular lab tests to map how GATA2, TGF‑β1, and TAL1 interact in NK cells. The team will test how changing these signals affects NK cell survival and function in laboratory models and patient samples. Their work builds on early data showing altered TAL1 and TGFB1 levels in NK cells from patients with GATA2 mutations.
Who could benefit from this research
Good fit: Ideal candidates are people with known GATA2 mutations or unexplained NK‑cell, B‑cell, or bone marrow failure syndromes who can provide blood or tissue samples.
Not a fit: People without immune cell disorders or conditions unrelated to NK/B‑cell dysfunction are unlikely to get direct benefit from this work.
Why it matters
Potential benefit: If successful, this work could reveal molecular targets to restore or improve NK cell function in people with GATA2‑related immune and bone marrow disorders.
How similar studies have performed: Previous work has established GATA2’s role in blood stem cells and NK development and the team has preliminary patient single‑cell data, but the specific GATA2–TGF‑β1–TAL1 network is a novel finding.
