Paracrine Action of Bone Morphogenetic Protein 3 in Pulmonary Arterial Hypertension

Aymen Halouani, Eric Mensiah, Mariem Ben Rhouma, Zaujia Athumani, Michael G. Katz, Seun Imani, Samar Antar, Katherine Jankowski, Maryam Mansoori, Vicki Rosen, Kiyotake Ishikawa, Lahouaria Hadri, Yassine Sassi

This study shows that BMP3 overexpression reduces pulmonary vascular remodeling and cardiac dysfunction in PAH by balancing TGF-β and BMP pathways through paracrine signaling.

Bidirectional Crosstalk Between Sleep and Pulmonary Arterial Hypertension

Seun Imani, Aymen Halouani, Jacob Dahlka, Nathan Burgess, Samar Antar, You‐Yang Zhao, Stephen Y. Chan, James D West, Matthew Weston, Yassine Sassi

This study shows poor sleep worsens pulmonary arterial hypertension (PAH) by inducing inflammation and PASMC proliferation, forming a self-amplifying cycle that can be mitigated by improving sleep and reducing inflammation.
