Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Regulated Protein Degradation

Regulated Protein Degradation

It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Alzheimer Disease ll: Pathophysiology

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...

Notch Signaling Pathway

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

Background:

Progranulin (PGRN) mutations are linked to frontotemporal dementia (FTD).
Pathogenic mutations often result in PGRN haploinsufficiency, leading to FTD.
Neuropathology includes tau-negative, ubiquitin-positive inclusions (FTLD-U) with TDP-43.

Purpose of the Study:

To review current knowledge on PGRN's role in neurodegenerative diseases.
To discuss molecular genetics, neuropathology, clinical phenotypes, and functional aspects of PGRN.
To explore PGRN's implications in frontotemporal dementia.

Main Methods:

Review of existing literature on Progranulin (PGRN).
Analysis of genetic, neuropathological, and clinical data related to PGRN mutations.
Discussion of PGRN's normal function and its role in the central nervous system (CNS).

Main Results:

PGRN mutations are a significant cause of frontotemporal dementia.
Clinical presentations vary widely among affected individuals and families.
PGRN's dual role in trophic support and inflammation is crucial in the CNS.

Conclusions:

Reduced PGRN levels impact neuronal survival and CNS inflammatory processes.
Understanding PGRN's function is key to developing therapies for FTD.
Further research into PGRN's molecular and cellular mechanisms is warranted.
