Mechanisms by which mitochondria undergo fusion and fission in hearts and elsewhere have been elaborated in detail and recently reviewed 6,7.Briefly, mitochondrial fusion is a three-step process (Figure): 1. On the other hand, induction of mitophagy, by any means (exercise, food. The dynamism of cardiac mitochondria dynamics proteins. The authors have declared no competing interest. Excessive mitochondrial fission has been associated with decreased. ![]() Results indicated significant overexpression of Fis1 in GC samples compared to adjacent normal tissues. Controlling mitochondrial dysfunction thus offers an exciting option for the development of therapies for TBI patients. Download scientific diagram Investigation of Fis1 expression using qRT-PCR. Pharmacological studies presented here suggest that fragmented mitochondria released by microglia are a key contributor to secondary neuronal damage progression after contusion injury, a pathway that requires astrocyte-microglia crosstalk. ![]() We developed a human three-dimensional in vitro triculture tissue model of a contusion injury, composed of neurons, microglia, and astrocytes, and examined the contributions of mitochondrial dysregulation to neuroinflammation and progression of injury-induced neurodegeneration. It is widely accepted that autophagic dysfunction is involved in pathogenesis of various neurodegenerative disorders however, the role of heavy metals in. ![]() However, cell-type-specific contributions and crosstalk between neurons, microglia, and astrocytes in mitochondria-driven neurodegeneration after brain injury remain undefined. Traumatic Brain injury-induced disturbances in mitochondrial fission-and-fusion dynamics have been linked to the onset and propagation of neuroinflammation and neurodegeneration. dysregulate ( third-person singular simple present dysregulates, present participle dysregulating, simple past and past participle dysregulated ) ( biology) To cause a dysfunctional level of an activity or chemical in an organism by disrupting normal function of a regulatory mechanism.
