Connexins and Pannexins in Vascular Function and Disease

Area of Science:

• Vascular Biology
• Cellular Physiology
• Membrane Protein Research

Background:

• Connexins (Cxs) and pannexins (Panxs) are integral membrane proteins forming channels.
• These channels facilitate ion and metabolite transport, crucial for intercellular communication.
• They play significant roles in maintaining vascular homeostasis and tissue health.

Purpose of the Study:

• To review the pathophysiological roles of Cx and Panx channels in the vasculature.
• To highlight the involvement of these channels in large arteries, microcirculation, veins, lymphatic system, and platelet function.
• To emphasize the link between Cx and Panx gene mutations/polymorphisms and vascular pathologies.

Main Methods:

• Literature review of current knowledge on connexins and pannexins in vascular physiology and pathology.
• Synthesis of information regarding channel function in different vascular components.
• Analysis of the impact of genetic variations on vascular health.

Main Results:

• Cx and Panx channels are critical for intercellular communication and tissue homeostasis.
• These channels are implicated in the pathophysiology of various vascular beds, including arteries, veins, and lymphatics.
• Mutations and polymorphisms in Cx and Panx genes are associated with vascular diseases.

Conclusions:

• Connexins and pannexins are essential for vascular homeostasis.
• Dysfunction of these channel proteins contributes significantly to vascular pathologies.
• Further research into Cx and Panx channels is crucial for understanding and treating vascular diseases.
