Exercise is emerging as a powerful adjuvant therapy during cancer treatment, partly due to its immunomodulatory effects. However, the moderate to vigorous intensities required for optimal immune-boosting effects are a barrier for many patients. β1-selective blockade may bias β2 adrenergic signaling to amplify immune responses at lower exercise intensities, offering a clinically feasible strategy for all cancer patients. SUMMARY: Enhancing β2 adrenergic receptor signaling in cancer patients may increase the beneficial effects of exercise on anti-tumor immunity.

Adrenergic Receptors: β Subtype
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
