Imbalances in gut microbiota are associated with metabolic disorder, which are a group of obesity-related metabolic abnormalities that increase an individual’s risk of developing type 2 diabetes (T2D) and Alzheimer’s disease (AD). Although a number of risk factors have been postulated that may trigger the development of AD, the root cause of this disease is still a matter of debate. This review further investigates the etiology of A Read More

This review presents a concise update on the inhibitors of the neuroenzyme, acetylcholinesterase (AChE; EC 3.1.1.7). AChE is a serine protease, which hydrolyses the neurotransmitter, acetylcholine into acetate and choline thereby terminating neurotransmission. Molecular interactions (mode of binding to the target enzyme), clinical applications and limitations have been summarized for each of the inhibitors discussed. Traditio Read More

Objectives: The present study compares the role and significance of non-high density lipoproteins (non-HDL) cholesterol level in pre-diabetic and diabetic patients. This study also compares non-HDL cholesterol level between males and females and with different age groups as well. Methods: An observational study was conducted among 3830 randomly selected individuals to envisage the association of non-HDL cholesterol an Read More

Diabetes mellitus (DM) is characterized by hyperglycemia either due to deficient insulin production (Type 1 Diabetes mellitus) or peripheral insulin resistance of the cells (Type 2 Diabetes mellitus). Both Type 1 Diabetes mellitus and Type 2 Diabetes mellitus are more prevalent and efforts are directed to actively control these metabolic syndromes. Currently, Alzheimer’s disease (AD), is gaining popularity as ‘Type 3 diabetes’ or Read More

Parkinson’s disease (PD) is the second most common neurodegenerative disease afflicting about 1% of people over 65 years old and 4-5% of people over 85 years. It is proposed that a cascade of deleterious factors is set in motion within that neuron made not of one, but rather of multiple factors such as free radicals, excitotoxicity, neuroinflammation, and apoptosis to cite only some of the most salient. In this scenario, chr Read More

Diabetes mellitus type 2 is a metabolic disorder characterized by high blood glucose due to insulin deficiency or resistance. Alzheimer's disease (AD) is a complex neurodegenerative disease leading to irreversible loss of neurons, intellectual abilities, memory and reasoning. The worldwide prevalence of diabetes and AD in elderly population is a major public health concern. Interestingly, both health issues are unraveling the Read More

Alzheimer's disease is a progressive degenerative disease of the brain marked by gradual and irreversible declines in cognitive functions. Acetylcholinesterase (AChE) plays a biological role in the termination of nerve impulse transmissions at cholinergic synapses by rapid hydrolysis of its substrate, "acetylcholine". The deficit level of acetylcholine leads to deprived nerve impulse transmission. Thus the cholinesterase inh Read More

Acetylcholinesterase (AChE) is a primary target for Alzheimer’s therapy while recently sodium glucose cotransporter 2 (SGLT2) has gained importance as a potential target for Type 2 Diabetes Mellitus (T2DM) therapy. The present study emphasizes the molecular interactions between a new Food and Drug Administration (FDA) approved antidiabetic drug ‘Invokana’ (chemically known as Canagliflozin) with AChE and SGLT Read More

The present study elucidates molecular interactions of human acetylcholinesterase (AChE), butyrylcholinesterase (BuChE) and 5-lipoxygenase (5-LPO) with a novel natural ligand Galangin (GAL); and also with the well-known ligands Bisnorcymserine (BNC) and Cymserine for comparison. Docking between these ligands and enzymes were performed using ‘Autodock4.2’. It was found that hydrophobic interactions play an im Read More

Chronic infection can cause slow progressive dementia, cortical atrophy and amyloid deposition in the atrophic form of general paresis. Due to the fact that specific bacterial ligands can increase the expression of proinflammatory molecules that can activate innate and adaptive immune systems, inflammation may play a significant role in the pathogenesis of Alzheimer’s disease (AD). Furthermore, there is a significant as Read More

Alzheimer disease (AD) and type 2 diabetes mellitus (T2DM) are chronic health disorders that affect millions of people around the world. According to recent studies, there are molecular similarities in the inflammatory pathways involved in both AD and T2DM, which opens a new avenue for researchers with different perspectives to target the cause of these diseases rather than their obvious symptoms. Several links between Read More

Alzheimer's disease (AD) and type 2 diabetes (T2D) are both prevalent in older individuals and have gained significant attention due to alarming rates of increase. The high incidences of these diseases pose a great socioeconomic burden and cause major public health concerns worldwide. A number of studies have established potential links between AD and T2D, supporting the hypothesis that T2D is linked with an increased ri Read More

The present study emphasizes the molecular interactions between human brain acetylcholinesterase (AChE) and the natural ligand Huperzine-B and its comparison to ‘AChE-Tolserine interactions’. Docking between Huperzine-B and AChE was performed using ‘Autodock4.2’. Hydrophobic interactions and hydrogen bonds both play an equally important role in the correct positioning of Huperzine-B within the ‘catalytic site’ o Read More

Alzheimer's disease, the most important neurodegenerative disorder, is an irreversible, age-dependent disease of the brain characterized by problems in progressive impairments in memory, language, reasoning, behavior and visuospatial skills. It is characterized by the deposition of amyloid beta peptide, forming compact fibrillar plaques and neurofibrillary tau tangles. Another major and much more prevalent cause Read More

Meta-analysis methods exist for combining multiple microarray datasets. However, there are a wide range of issues associated with microarray meta-analysis and a limited ability to compare the performance of different metaanalysis methods. Using cDNA microarray technology (Partek Genomics Suite 6.6) and global pathway analysis with Ingenuity Pathway Analysis tool (IPA, Inc), we examined the transcript level in type Read More

Insulin-degrading enzyme (IDE) is a key protease involved in degrading insulin and amyloid peptides in human body. Several non-synonymous genetic mutations of IDE gene have been recently associated with susceptibility to both diabetes and Alzheimer’s diseases. However, the consequence of these mutations on the structure of IDE protein and its substrate binding characteristics is not well elucidated. The com Read More

Alzheimer’s disease (AD) is a neurodegenerative disorder that leads to memory problems. It has been associated with type 2 diabetes mellitus at both the molecular and biochemical level. Pancreatic cells have molecular similarities to the brain at the transcriptomic and proteomic levels. Several genes have been reported to be responsible for both AD and diabetes. Currently, no proper treatment is available but various th Read More

The prevalence of Alzheimer’s disease (AD) is higher among type 2 diabetes mellitus (T2DM) patients. In T2DM patients, the progression of AD is more rapid. Furthermore, several pathophysiological pathways are common to AD and T2DM. Humanin is a recently introduced, mitochondrial-derived peptide with neuroprotective effects. Humanin can alter the mechanisms involved in AD and T2DM pathogenesis. Insulin resista Read More
