Understanding how aging affects immune responses to pneumonia after influenza infection

The role of PMNs and CD73 in host-resistance against S. pneumoniae / influenza A virus co-infection

NIH-funded research State University of New York at Buffalo · NIH-10795038

This study is looking at how getting the flu can make older adults more likely to develop pneumonia from a bacteria called Streptococcus pneumoniae, and it aims to find new ways to help boost their immune system against these infections.

What this research studies

This research investigates how influenza A virus infection increases the risk of pneumonia caused by Streptococcus pneumoniae, particularly in older adults. It focuses on the role of specific immune cells, known as polymorphonuclear leukocytes (PMNs), and a pathway involving adenosine that influences immune responses. By studying these mechanisms, the research aims to identify novel strategies to enhance resistance to infections in aging populations. The approach includes both animal models and human studies to better understand the interactions between these infections.

Who could benefit from this research

Good fit: Ideal candidates for this research are older adults, particularly those who have experienced influenza infections or are at risk for pneumonia.

Not a fit: Patients who are younger and have no history of influenza or pneumonia may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved treatments and preventive strategies for pneumonia in older adults following influenza infections.

How similar studies have performed: Previous research has shown promising results in understanding immune responses in similar contexts, suggesting that this approach could yield valuable insights.
