IL-17's role in immune control of long-term viral infections

IL-17 regulation of type-1 immunity in chronic viral infection

NIH-funded research Cornell University · NIH-11091499

This research looks at whether the immune signal IL-17 changes how other immune cells behave during long-lasting viral infections, which could matter for people with chronic viral illnesses.

What this research studies

Researchers are using a well-established mouse model of chronic viral infection (LCMV clone 13) to see how IL-17 influences immune cell activation, exhaustion, and tissue damage. They block IL-17 using genetic methods and antibodies and measure effects on Th1 and CD8+ T cells, along with gene expression changes. The team is studying lymphoid stromal fibroblastic reticular cells (FRCs) as intermediaries of IL-17's effects and looking at the role of excess IFN-gamma in driving exhaustion. Findings aim to clarify whether modulating IL-17 could reduce harmful chronic inflammation without worsening infection.

Who could benefit from this research

Good fit: People living with chronic viral infections (for example, long-term hepatitis or other persistent viral illnesses) would be the most relevant future candidates for therapies informed by this work.

Not a fit: Patients with acute, short-term infections or non-viral conditions are unlikely to receive direct benefit from this basic immunology research.

Why it matters

Potential benefit: If successful, this work could point to new ways to reduce damaging inflammation and improve immune control in people with chronic viral infections.

How similar studies have performed: While IL-17's role is well known in bacterial, fungal, and autoimmune inflammation, using IL-17 blockade to alter T cell exhaustion in chronic viral infection is relatively new and yielded unexpected findings in this model.
