A new study about dysregulated autoantibodies in Post COVID Syndrome (PCS) has been published in Frontiers in Immunologie!
Nearly 160 patients were included in the study and divided into four groups. Most PCS patients present a plethora of symptoms without clear evidence of organ dysfunction. The symptom severity of ME/CFS correlates with natural regulatory autoantibody (AAB) levels targeting several G-protein coupled receptors (GPCR). This study identified the dysregulation of AAB against various receptors and their correlation with symptom severity. Remarkably, severity of fatigue and vasomotor symptoms were associated with ADRB2 AAB levels in PCS/ME/CFS patients.
