Many gliomas exhibit cells that do not exist in normal brain tissue and are not seen in glial differentiation. [1] Of these gliomas are astrocytomas, which is a type of cancer that occurs in the brain or spinal cord. The main role of astrocytes is to maintain brain homeostasis and neuronal metabolism.
Neurodegenerative diseases such as Alzheimer's, Parkinson's, and Huntington's are all age-related diseases and involve increased apoptosis where cells die that are still able to function or that contribute to support function of tissue. Apaf-1-ALT is an Apaf-1 mutant found in prostate cancer, which does not have residues 339-1248.
The cytoplasm describes all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles [1] and excluding the nucleus in eukaryotic cells. The material inside the nucleus of a eukaryotic cell and contained within the nuclear membrane is termed the nucleoplasm .
The specific results of cell ablation and isolation that highlights autonomously specified cells are the following. If ablation of a tissue from a certain cell occurred, the cell will have a missing part. As a result, the removed tissue was autonomously specified since the cell was not able to make up for the missing part.
Apoptosis is known to be one of the primary mechanisms of targeted cancer therapy. [42] Luminescent iridium complex-peptide hybrids (IPHs) have recently been designed, which mimic TRAIL and bind to death receptors on cancer cells, thereby inducing their apoptosis. [43]
Cell fusion is an important cellular process in which several uninucleate cells (cells with a single nucleus) combine to form a multinucleate cell, known as a syncytium.Cell fusion occurs during differentiation of myoblasts, osteoclasts and trophoblasts, during embryogenesis, and morphogenesis. [1]
Defining cerebral cytoarchitecture began with the advent of histology—the science of slicing and staining brain slices for examination. [2] It is credited to the Viennese psychiatrist Theodor Meynert (1833–1892), who in 1867 noticed regional variations in the histological structure of different parts of the gray matter in the cerebral hemispheres.
Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges , blood vessels , and ducts. The two main types of cells in the brain are neurons , also known as nerve cells, and glial cells , also known as neuroglia. [ 1 ]
