Virax Biolabs Unveils Findings on T-Cell Dysfunction at Conference
Virax Biolabs' Research Highlights T-Cell Dysfunction Impact
Virax Biolabs Group Limited (NASDAQ: VRAX) is at the forefront of advancing our understanding of immune responses and the diagnosis of viral diseases. The company recently showcased pivotal findings on T-Cell dysfunction related to post-acute infection syndromes (PAIS) at a renowned international immunology meeting. This research sheds light on the significant association between immune system impairments and conditions such as long COVID and other chronic syndromes.
Understanding Post-Acute Infection Syndromes
Post-acute infection syndromes, or PAIS, typically manifest through complications resulting from infections that persist or evolve over time. Virax Biolabs' findings indicate that chronic infections lead to T-Cell exhaustion, which in turn affects the body's immune response. This happens due to the repeated activation of T-Cells in response to viral pathogens, resulting in the expression of exhaustion markers and reduced functionality of these immune cells.
Research Findings on T-Cell Exhaustion
The recent data from Virax revealed that when peripheral blood mononuclear cells (PBMCs) were repeatedly stimulated with specific peptide pools related to SARS-CoV-2 and CMV, there was an observable increase in both CD4+ and CD8+ T-Cells that exhibited exhaustion characteristics. The exhaustion markers—PD-1, LAG-3, TIGIT, TIM-3, and CD39—were significantly more prevalent after each stimulation event. This decline in T-Cell efficiency directly correlates to diminished cytokine production, hampering the immune system's ability to respond adequately to infections.
Clinical Implications and Future Directions
Nigel McCracken, the Chief Operating Officer at Virax Biolabs, emphasized the urgent relevance of these findings in the context of chronic syndromes like long COVID and chronic fatigue, stating, "This data highlights the critical role of T-Cell exhaustion in immune dysfunction, particularly in PAIS conditions." The company is committed to pursuing further clinical validation studies to explore the relationship between T-Cell dysfunction and the spectrum of symptoms associated with conditions such as cognitive impairment and chronic fatigue.
ViraxImmune™ PAIS Assay Insights
Preliminary results from Virax’s proprietary ViraxImmune™ PAIS assay have also shown noteworthy changes in cytokine levels among patients with PAIS when compared to healthy individuals. This examination of cytokine balances could be crucial in identifying specific pathways involved in immune dysregulation, potentially leading to novel therapeutic approaches.

Frequently Asked Questions
What is T-Cell dysfunction?
T-Cell dysfunction refers to the impaired functioning of T-Cells, which are critical components of the immune system, limiting their ability to respond effectively to infections.
How does Virax Biolabs study T-Cell dysfunction?
Virax utilizes advanced assays and clinical studies to evaluate the performance of T-Cell responses in patients with post-acute infection syndromes.
What are post-acute infection syndromes (PAIS)?
PAIS refer to lingering health issues that occur after an acute infection, often impacting immune function and causing symptoms like fatigue and cognitive difficulties.
What are some diseases associated with T-Cell exhaustion?
T-Cell exhaustion is commonly linked to chronic conditions like long COVID, chronic fatigue syndrome (ME/CFS), and chronic Lyme disease.
