Beta-1 receptors are found in the heart, and when stimulated will increase herat rate and cardiac contractility. Beta-2 receptors are found on vascular smooth muscle located in the heart and skeletal muscle, and when they are activated, they dilate and decrease SVR.
Viral receptors can also be species specific. The poliovirus receptor, for instance, is only found on primate cells [11]. How an individual virus evolves to make use of a particular cellular receptor is an intriguing and unresolved question. This issue is pertinent to proteinâprotein recognition on cell surfaces.
