Abstract

Alzheimer's disease, a neurodegenerative disorder, is characterized by cognitive impairment, neuronal loss, and synaptic dysfunction. The interplay between the phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) signaling pathway and the caspase-mediated apoptotic cascade plays a pivotal role in its progression. The signaling pathway responsible for neuronal survival also regulates synaptic plasticity and resistance to oxidative stress, whereas caspase activation accelerates neurodegeneration by triggering cell death and inflammation. Dysregulation of these pathways leads to amyloid-beta (Aβ) accumulation, tau hyperphosphorylation, and mitochondrial dysfunction, creating a negative feedback loop and accelerating disease progression. Emerging treatment methods that target PI3K/AKT activation and caspase inhibition have showed promise in preclinical models, preventing neuronal apoptosis while retaining cognitive function. This review investigates the molecular processes driving PI3K/AKT and caspase crosstalk, their significance in Alzheimer's disease, and prospective therapeutic strategies aiming at regulating these pathways to improve disease outcomes.

期刊介绍: Inflammopharmacology is the official publication of the Gastrointestinal Section of the International Union of Basic and Clinical Pharmacology (IUPHAR) and the Hungarian Experimental and Clinical Pharmacology Society (HECPS). Inflammopharmacology publishes papers on all aspects of inflammation and its pharmacological control emphasizing comparisons of (a) different inflammatory states, and (b) the actions, therapeutic efficacy and safety of drugs employed in the treatment of inflammatory conditions. The comparative aspects of the types of inflammatory conditions include gastrointestinal disease (e.g. ulcerative colitis, Crohn''s disease), parasitic diseases, toxicological manifestations of the effects of drugs and environmental agents, arthritic conditions, and inflammatory effects of injury or aging on skeletal muscle. The journal has seven main interest areas: -Drug-Disease Interactions - Conditional Pharmacology - i.e. where the condition (disease or stress state) influences the therapeutic response and side (adverse) effects from anti-inflammatory drugs. Mechanisms of drug-disease and drug disease interactions and the role of different stress states -Rheumatology - particular emphasis on methods of measurement of clinical response effects of new agents, adverse effects from anti-rheumatic drugs -Gastroenterology - with particular emphasis on animal and human models, mechanisms of mucosal inflammation and ulceration and effects of novel and established anti-ulcer, anti-inflammatory agents, or antiparasitic agents -Neuro-Inflammation and Pain - model systems, pharmacology of new analgesic agents and mechanisms of neuro-inflammation and pain -Novel drugs, natural products and nutraceuticals - and their effects on inflammatory processes, especially where there are indications of novel modes action compared with conventional drugs e.g. NSAIDs -Muscle-immune interactions during inflammation [...]
