Androgen receptor(AR)is a major transcription factor that plays a role in inflammatory response including interleukin-6(IL6)signaling.1 while AR regulation through paracrine loop signaling in prostate tissue is well-studied,its impact through an IL6 autocrine loop in the lung has not been wellstudied despite the organ's response to respiratory viral *** inhibition and RNA knockdown of AR identified a bZIP transcription factor mAF to be a common target of inflammation using these perturbations in lung cells.
