Why fatigue from long COVID goes beyond simply feeling tired

In a latest research posted to the medRxiv* preprint server, researchers within the Netherlands examined the position of inflammatory genes, cytotoxic T-lymphocytes (CD8+  T cells), and pro-inflammatory cytokines in long-lasting extreme fatigue skilled by numerous coronavirus illness 2019 (COVID-19) sufferers.

Study: Severe fatigue as symptom of long COVID is characterized by increased expression of inflammatory genes in monocytes, increased serum pro-inflammatory cytokines, and increased CD8+ T-lymphocytes: A putative dysregulation of the immune-brain axis, the coagulation process, and auto-inflammation to explain the diversity of long COVID symptoms.
