The persistence of SARS-CoV-2 antigens, chronic inflammation, reactivation of latent herpes viruses, and decreased cortisol levels were detected in long COVID patients more than one year after acute infection
Biological (immunological, virological and hormonal) features of long COVID syndrome more than one year after acute infection.
Increased circulating levels of HERV-W envelope proteins and proinflammatory cytokines in SARS-CoV-2-positive patients hospitalized for psychosis spectrum disorders
This study demonstrated increased expression of HERV-W ENV proteins and proinflammatory cytokines only in hospitalized patients with psychosis spectrum disorders who were positive for SARS-CoV-2, suggesting a strong link between HERV-W activation, cytokine expression and SARS-CoV-2 infection.

Circulating HERV-W envelope proteins and elevated levels of anti-SARS-CoV-2 IgE antibodies were detected in patients with post-COVID syndrome one year after the acute infection
HERV-W ENV protein was expressed in 58% of plasma samples of post-COVID patients, long after the acute SARS-CoV-2 infection was resolved .75% of post-COVID patients had elevated levels of anti-S and anti-N IgE antibodies compared to pre-pandemic controls.
