Official title: CD4 Th1 Cell Restoration for Control of Chronic Viral Infection

Funded at Indiana University Indianapolis · NIH-11449036 · Data updated 2026-11-12

A research project tests a strategy to revive CD4 Th1 helper T cells to better control chronic viral infections like HIV and hepatitis B/C in people who need improved immune control.

Who could benefit from this research

Could help

Ideal candidates are adults with chronic viral infections (e.g., HIV, hepatitis B or C) who may benefit from restored CD4 Th1 and CD8 T cell responses.

Less likely to help

Patients with advanced disease or other immunodeficiencies may see limited benefit from this approach.

What this research studies

This project aims to restore and sustain CD4 Th1 T cell responses in people with chronic viral infections. By reconstituting these helper cells, the therapy seeks to boost the activity of CD8 T cells and promote viral clearance. The approach includes findings that anti-PD-L1 treatment can selectively enhance virus-specific CD4 Th1 cells and improve immune control, potentially reducing viral persistence. The work involves preclinical and translational studies to understand how restoring CD4 Th1 function could translate into better patient outcomes. If successful, this could lead to new immune-based strategies to complement antivirals and prevent viral rebound.

Why it matters

Potential benefit: If successful, patients could experience improved viral control and reduced risk of viral rebound when stopping antivirals.

How similar studies have gone: Prior work suggests that boosting CD4 Th1 responses can enhance CD8 T cell function and viral control, supporting further development of this strategy.
