Strange microscopic structures found in Long COVID blood

📊 Healthcare News Analysis: Our editorial team has analyzed recent developments from sciencedaily.com in the Healthcare sector. This report covers key insights related to medical treatment, surgery, prescription and emerging industry trends that professionals should monitor closely.

Industry observers in Healthcare are monitoring emerging trends closely. The researchers also incorporated Artificial Intelligence tools, including machine learning, to analyze biomarker patterns. These methods allowed them to accurately differentiate Long COVID patients from healthy individuals and to pinpoint the most informative biomarker combinations.

Such insights could support more precise diagnostics and future personalized treatments. According to reports that what are neutrophil extracellular traps (NETs)? Alain Thierry and his group at the Montpellier Cancer Institute (IRCM) at INSERM in Montpellier were among the first to highlight the importance of NETs in COVID-19.

NETs form when neutrophils release their DNA through a process called NETosis, creating thread-like structures filled with harmful enzymes that can quickly trap and neutralize invading microbes. Although NETs help defend against infection, producing too many of them can be harmful. Excess NET formation has been linked to serious inflammatory and clotting conditions, including severe infections, autoimmune diseases, cancer, diabetes, and arthritis.

Thierry notes that ongoing overproduction of NETs, driven by cycles of inflammation and clot formation, may worsen disease severity. Sources indicate that in light of this, the teams led by Prof Pretorius and Dr. According to reports that thierry worked together to examine whether microclots and NETs interact in patients with Long COVID. Key findings
Using imaging flow cytometry and fluorescence microscopy, the researchers conducted detailed measurements of microclots and NETs in the plasma of individuals with Long COVID and compared the results to healthy controls.

They also quantified NETs by assessing proteic markers and circulating DNA. They reported several major observations:
“This finding suggests the existence of underlying physiological interactions between microclots and NETs that, when dysregulated, may become pathogenic,” explains Dr. Data shows that the researchers also incorporated Artificial Intelligence tools, including machine learning, to analyze biomarker patterns.

These methods allowed them to accurately differentiate Long COVID patients from healthy individuals and to pinpoint the most informative biomarker combinations. Sources indicate that such insights could support more precise diagnostics and future personalized treatments. Prof Pretorius emphasizes that the study reveals a buildup of microclots in the plasma of Long COVID patients, likely supported by excessive NET activity: “This interaction could render microclots more resistant to fibrinolysis, promoting their persistence in circulation and contributing to chronic microvascular complications,” she explains.

By clarifying how NETs may stabilize microclots, the study contributes valuable information about the biological processes involved in Long COVID. The findings also highlight potential therapeutic approaches aimed at reducing harmful clotting and inflammation. In addition, the work advances the search for new biomarkers that could help diagnose and manage Long COVID.

Evidence suggests that as the authors note, “The combination of advanced imaging techniques and machine learning confers methodological robustness and contributes significantly to the ongoing scientific discourse on post-viral syndromes.”
In patients with Long COVID, a new study has revealed structural association between circulating microclots and neutrophil extracellular traps (NETs). Evidence suggests that this finding suggests the existence of underlying physiological interactions between microclots and NETS that, when dysregulated, may become pathogenic. The term microclots, recently adopted in the scientific literature, refers to abnormal clumps of blood clotting proteins circulating in a patient’s blood stream. Sources indicate that the concept was introduced in 2021 by Prof.

Resia Pretorius from Stellenbosch University’s Department of Physiological Sciences, when they found the abnormal presence of such microclots in the blood samples of COVID-19 patients. Data shows that this discovery generated widespread attention during the pandemic due to its potential role in COVID-related coagulopathies. What are neutrophil extracellular traps (NETs)? Alain Thierry’s team at the Montpellier Cancer Institute (IRCM) at INSERM in Montpellier, was among the first to identify the critical role of NETs in the pathogenesis of COVID-19.

NETs are produced through a specialised form of innate immune response known as NETosis, whereby neutrophils expel their DNA to form filamentous structures embedded with cytotoxic enzymes capable of rapidly trapping and neutralizing pathogens. However, excessive NETs formation can become detrimental, contributing to a wide range of inflammatory and thrombotic diseases, including severe infections, autoimmune disorders, cancer, diabetes, and arthritis. Thierry, it may be that persistent overproduction of NETs, fueled by self-perpetuating inflammatory and thrombotic loops, exacerbates disease severity.

Sources indicate that in a collaborative effort, the teams of Prof. Evidence suggests that thierry investigated the potential interaction between microclots and NETs in the context of Long COVID. Key findings
Using imaging flow cytometry and fluorescence microscopy, they performed a quantitative and structural analysis of microclots and NETs in the plasma of Long COVID patients, compared to healthy controls.

According to reports that nETs were also quantified by analyzing NETs proteic markers and circulating DNA. “This finding suggests the existence of underlying physiological interactions between microclots and NETs that, when dysregulated, may become pathogenic,” explains Dr. Furthermore, the integration of Artificial Intelligence tools, such as machine learning, into the biomarker analysis enabled them to distinguish Long COVID patients from healthy individuals with high accuracy. Evidence suggests that the algorithms identified the most predictive biomarker combinations, enhancing diagnostic reliability and paving the way for personalized medicine approaches.

According to reports that pretorius, the results reveal a significant accumulation of microclots in the plasma of Long COVID patients, likely driven and stabilized by excessive NETs production: “This interaction could render microclots more resistant to fibrinolysis, promoting their persistence in circulation and contributing to chronic microvascular complications,” she explains. By identifying the mechanistic role of NETs in microclot stabilization, this study provides new insight into the pathophysiology of Long COVID. According to reports that these findings support the development of targeted therapeutic strategies aimed at modulating thrombo-inflammatory responses. Finally, the study paves the way for the development of novel biomarkers for diagnosis and management: “The combination of advanced imaging techniques and machine learning confers methodological robustness and contributes significantly to the ongoing scientific discourse on post-viral syndromes,” they conclude.
