Calcium is a ubiquitous signaling component of neuronal functions. Calcium regulation is a complex phenomenon that is controlled by cellular organelles. Abnormality created by amyloid plaques is a crucial phenomenon in which the [Ca2+] flux enters through the plasma membrane. Entry of such flux is managed by intracellular homeostasis. In the neuronal calcium homeostasis, any alteration could lead to neurodegener-ation. In this paper, the effect of various parameters like SERCA, IPR, Leak, VGCC, etc. has been investigated. A mathematical model has been developed by considering a time-fractional differential approach to investigate the non-local impact on cytosolic [Ca2+]. An analytic solution was obtained by applying the Laplace transform, Fourier cosine transform, and Green’s function. The significant implication of amyloid beta, endoplas-mic reticulum flux, and plasma membrane flux on calcium signaling was observed. It is also observed that Amyloid beta created pores are toxic to the neuron. The effect of S100B, EGTA, and BAPTA with diffusion coefficient observed neuroprotective properties for calcium signaling. From all this simulation therapeutic insight from different buffers and amyloid plaques can be observed which is a better fit as per realistic physiology.
