Mitochondrial Biology and Parkinson's Disease

Mitochondrial biology and Parkinson's disease.

Mitochondria are highly dynamic organelles with complex structural features which play several important cellular functions, such as the production of energy by oxidative phosphorylation, the regulation of calcium homeostasis, or the control of programmed cell death (PCD). Given its essential role in neuronal viability, alterations in mitochondrial biology can lead to neuron dysfunction and cel...

The biology of mitochondrial disease.

Mitochondrial Function, Biology, and Role in Disease

1960 Abstract—Cardiovascular disease is a major leading cause of morbidity and mortality in the United States and elsewhere. Alterations in mitochondrial function are increasingly being recognized as a contributing factor in myocardial infarction and in patients presenting with cardiomyopathy. Recent understanding of the complex interaction of the mitochondria in regulating metabolism and cell ...

Biology of TH17 Lymphocytes, their Cytokines and Role in Disease

T lymphocytes that are involved in cellular mediated immunity include two types known as TCD8+ (Cytotoxic T lymphocytes) and TCD4+ (helper T lymphocytes). TCD4+ has four main subtypes, including TH1, TH2, TH17, and Treg Lymphocytes.TH17 lymphocytes play a role in defense against microbes that TH1 and TH2 lymphocytes have not the ability to respond to them. The most important cytokines, which ar...

Prohibitin and mitochondrial biology.

Prohibitins are ubiquitous, evolutionarily conserved proteins that are mainly localized in mitochondria. The mitochondrial prohibitin complex comprises two subunits, PHB1 and PHB2. These two proteins assemble into a ring-like macromolecular structure at the inner mitochondrial membrane and are implicated in diverse cellular processes: from mitochondrial biogenesis and function to cell death and...
