2015 study Pathway-focused genetic evaluation of immune and inflammation related genes with chronic fatigue syndrome Mangalathu S. Rajeevan, Irina Dimulescu, Janna Murray 1, Virginia R. Falkenberg, Elizabeth R. Unger Abstract Recent evidence suggests immune and inflammatory alterations are...

Abstract: The hemostatic system prevents and stops bleeding, maintaining circulatory integrity after injury. It directly interacts with the complement system, which is key to innate immunity. In coronavirus disease 2019 (COVID-19), dysregulation of the hemostatic and complement systems has been...

Unraveling SARS-CoV-2 Host-Response Heterogeneity through Longitudinal Molecular Subtyping Hospitalized COVID-19 patients exhibit diverse immune responses during acute infection, which are associated with a wide range of clinical outcomes. However, understanding these immune heterogeneities...

ABSTRACT The complement system is a vital anti-microbial defence mechanism against circulating pathogens. Excessive complement activation can have deleterious outcomes for the host and is consequently tightly modulated by a set of membrane-associated and fluid-phase regulators of complement...

Abstract Life-threatening thrombotic events and neurological symptoms are prevalent in COVID-19 and are persistent in patients with long COVID experiencing post-acute sequelae of SARS-CoV-2 infection1,2,3,4. Despite the clinical evidence1,5,6,7, the underlying mechanisms of coagulopathy in...

Abstract Myalgic Encephalomyelitis (ME; sometimes referred to as chronic fatigue syndrome) is a relatively common and female-biased disease of unknown pathogenesis that profoundly decreases patients' health-related quality-of-life. ME diagnosis is hindered by the absence of robustly-defined and...
