Improving T cell function in older adults using a special protein treatment

Official title: Treating T cell immunodeficiency among older adults by a recombinant Foxn1 fusion protein

Funded at University of Connecticut Storrs · NIH-11094822 · Data updated 2026-11-12

This study is looking at a new way to help older adults boost their immune system by using a special protein to improve the thymus, which is important for making T cells that fight off infections.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults experiencing T cell immunodeficiency or related immune challenges.

Less likely to help

Patients who are younger than 21 years old or those without any immune deficiencies may not benefit from this research.

What this research studies

This research investigates a novel approach to enhance T cell development in older adults, who often experience a decline in immune function due to aging. The study focuses on a recombinant FOXN1 fusion protein that aims to rejuvenate the thymus, the organ responsible for T cell maturation. By injecting this protein directly into the thymus, the researchers hope to increase the number of thymic epithelial cells, which are crucial for T cell production. This could potentially lead to improved immune responses and better protection against infections and diseases in older individuals.

Why it matters

Potential benefit: If successful, this research could significantly improve the immune health of older adults, reducing their susceptibility to infections and enhancing the effectiveness of vaccinations.

How similar studies have gone: While the approach of using FOXN1 fusion proteins is innovative, similar strategies targeting thymic rejuvenation have shown promise in preliminary studies, indicating potential for success.
