Investigating how tau protein affects brain function in people with HIV and opioid use disorder

Official title: pTau-related neuron and cognitive dysfunction in opioid-HIV comorbidity: Longitudinal and functional studies

Funded at Virginia Commonwealth University · NIH-11067820 · Data updated 2026-11-12

This study is looking at how a protein called tau might affect thinking and memory in people with HIV who also use opioids, to see if reducing tau could help improve their brain health and cognitive skills over time.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals living with HIV who also have a diagnosis of opioid use disorder.

Less likely to help

Patients who do not have HIV or opioid use disorder may not benefit from this research.

What this research studies

This research focuses on understanding the relationship between abnormal tau protein and cognitive dysfunction in individuals living with HIV who also have opioid use disorder. It aims to clarify whether the accumulation of phosphorylated tau protein contributes to cognitive decline and neuron dysfunction in these patients. By conducting longitudinal and functional studies, the research will explore the effects of tau on brain health and cognitive abilities over time. The findings could help identify potential therapeutic targets for improving cognitive function in affected individuals.

Why it matters

Potential benefit: If successful, this research could lead to new strategies for preventing or treating cognitive decline in patients with HIV and opioid use disorder.

How similar studies have gone: Previous research has shown that tau protein plays a significant role in cognitive disorders, suggesting that this approach could yield valuable insights.
