Ca2Dynamik
Ca2Dynamik is a term used to describe the dynamic behavior of intracellular calcium ions (Ca2+) in biological systems. It encompasses the temporal changes in Ca2+ concentration and the spatial patterns that arise from signaling events, diffusion, and organellar interactions. In many contexts, Ca2Dynamik refers both to experimental observations of Ca2+ transients and to theoretical models that seek to explain their origin and consequences.
Calcium dynamics arise from entry through plasma membrane channels (voltage-gated, ligand-gated), release from internal stores such
In neurons, Ca2+ signals regulate neurotransmitter release and plasticity; in muscle cells, Ca2+ controls contraction; in
Modeling approaches include diffusion-reaction equations, buffering models, and stochastic simulations to capture spatial and temporal aspects.
