Severe COVID-19 reveals distinct immune patterns tied to metabolism, not just antiviral response

Article excerpt

Researchers at Karolinska Institutet have identified distinct immune patterns in severe COVID-19 patients that link metabolism to disease progression, not merely antiviral response strength. The findings, published in Genome Medicine, reveal that how the immune system interacts with the body's metabolic processes, rather than the vigor of antiviral defenses alone, may determine whether COVID-19 becomes severe. The discovery suggests that different patients mount different immune strategies against the virus, and these variations correlate with metabolic shifts. Understanding these patterns could reshape how doctors predict which patients will develop critical illness and potentially guide more targeted treatment approaches.
