Abstract:

Parkinson's disease (PD) is a chronic neurodegenerative condition which has the second largest incidence rate among all other neurodegenerative disorders barring Alzheimer's disease (AD). Currently there is no cure and researchers continue to probe the therapeutic prospect in cell cultures and animal models of PD. Out of several factors contributing to PD prognosis, the role of p38 MAPKs (mitogen-activated protein (MAP) kinase) and PI3K/AKT signalling module in PD brains is crucial because impaired balance between the pro-apoptotic and anti-apoptotic pathways trigger unwanted phenotypes such as microglia activation, neuroinflammation, oxidative stress, and apoptosis. These factors continue challenging the brain homeostasis in initial stages thereby essentially assisting the dopaminergic (DA) neurons towards progressive degeneration in PD. Neurotherapeutics against PD shall then be targeted against the misregulated accomplices of the p38 and PI3K/AKT cascades. In this review, we have outlined many such established mechanism involving the p38 MAPK and PI3K/AKT pathways which can offer therapeutic windows for rectification of aberrant DA neuronal dynamics in PD brains.

Mechanisms and functions of p38 MAPK signalling.

The p38 MAPK (mitogen-activated protein kinase) signalling pathway allows cells to interpret a wide range of external signals and respond appropriately by generating a plethora of different biological effects. The diversity and specificity in cellular outcomes is achieved with an apparently simple linear architecture of the pathway, consisting of a core of three protein kinases acting sequentia...

Rewriting Game Theory Applied to Protein Signalling in MAPK Cascades

We propose the recent notion of rewriting game theory as a tool for studying biochemical systems. Rewriting game theory is based on a discrete and dynamic notion of Nash-style equilibria for games without structural constraints and with arbitrary payoff values. Our aim here is to show how the formalism can be used to characterise biological information as logical properties of a purely chemical...

p38 MAPK in MDS

(MDS) are a group of heterogeneous hematopoietic malignancies occurring mainly in the elderly and characterized by the defective production of mature blood cells. MDS subtypes can be classified as " low-risk " and " high-risk " syndromes on the basis of their risk of progression to acute leukemia. Although progression to leukemia is the most common cause of death in high-risk patients, infectio...
