WebSep 30, 2024 · However, signal compartmentalization may arise at different levels, including (i) receptor spatiotemporal compartmentalization at the subcellular level; (ii) the local modulation of the interaction of the receptors with their downstream signaling partners; and (iii) the compartmentalization of the second messengers ( Calebiro et al, 2024; Bers et … WebJun 15, 2024 · 2. PDE4 and cAMP: Structural and Functional Features. Phosphodiesterase 4 (PDE4) is one of the low K m enzymes that catalyzes the breakdown of cAMP in several immune cell types, such as macrophages and T cells []; this leads to reduced intracellular levels of cAMP, that is ultimately hydrolyzed to inactive 5′-AMP.In mammalian species …
