Connexins and Aging-Associated Respiratory Disorders: The Role in Intercellular Communications.
Abstract
This article reviews the contemporary understanding of the functional role of connexins in intercellular communications, their involvement in maintaining cellular and tissue homeostasis, and in aging-associated respiratory disease pathogenesis. Connexins are discussed as potential therapeutic targets. The review particularly focuses on the involvement of gap junction connexins and hemichannels in the transfer of calcium ions, metabolite molecules, ATP, and mitochondria through the cell membrane. Various disorders in the regulation of intercellular communication can heavily contribute to the pathogenesis of multiple diseases, including respiratory system diseases. A deeper understanding of molecular mechanisms underlying the activities of various connexins in gap junction channels will enable the prospective development of therapeutic approaches by either inhibiting or stimulating the activities of a certain connexin, while considering its critical functions in intercellular communications on the whole.

Research summary
The paper discusses the role of connexins in intercellular communication and their potential involvement in aging-associated respiratory disorders. While it touches on mechanisms that could relate to aging, it primarily focuses on the pathogenesis of diseases rather than addressing the root causes of aging itself. The therapeutic implications mentioned are interesting but do not significantly advance the understanding of aging or lifespan extension. Thus, it is a solid contribution but with limited impact.
