Matrix metalloproteinases (MMPs) are a family of zinc-dependent extracellular matrix (ECM) remodeling endopeptidases that have the capacity to degrade almost every component ECM. The degradation ECM is great importance, since it related embryonic development and angiogenesis. It also involved in cell repair tissues. When expression MMPs altered, can generate abnormal This initial cause chronic degenerative diseases vascular complications generated by diabetes. In addition, this process has an association with neurodegeneration cancer progression. Within ECM, tissue inhibitors (TIMPs) inhibit proteolytic activity MMPs. TIMPs important regulators turnover, remodeling, cellular behavior. Therefore, (similar MMPs) modulate angiogenesis, proliferation, apoptosis.

Summary

Decades of research have identified genetic factors and biochemical pathways involved in neurodegenerative diseases (NDDs). We present evidence for the following eight hallmarks NDD: pathological protein aggregation, synaptic neuronal network dysfunction, aberrant proteostasis, cytoskeletal abnormalities, altered energy homeostasis, DNA RNA defects, inflammation, cell death. describe hallmarks, their biomarkers, interactions as a framework to study NDDs using holistic approach. The can serve basis defining pathogenic mechanisms, categorizing different based on primary stratifying patients within specific NDD, designing multi-targeted, personalized therapies effectively halt NDDs.

The concept of ‘idiopathic’ Parkinson’s disease (PD) as a single entity has been challenged with the identification several clinical subtypes, pathogenic genes and putative causative environmental agents.

However, mechanisms linking α-synuclein pathology neuronal death to microglial neuroinflammation have not been completely elucidated.
