Neurological, neurochemical, genomic, environmental, psychogenic, and immunological factors are thought to be involved in GAD. However, studies conducted to establish any suitable biomarkers for the assessment of anxiety disorder is limited. Hence, we aim to investigate the serum levels of interleukin\u20106 (IL\u20106) and transforming growth factor\u2010beta 1 (TGF\u2010\u03b21) in GAD patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>The present study enrolled 44 GAD patients and 44 healthy controls (HCs) from a tertiary care teaching hospital in Dhaka, Bangladesh.
