Astrocytic Tumors

2009
Astrocytic gliomas are the most common primary brain tumors and account for up to two thirds of all tumors of glial origin. In this review we outline the basic histological and epidemiological aspects of the different astrocytoma subtypes in adults. In addition, we summarize the key genetic alterations that have been attributed to astrocytoma patho ...

Hypothalamic Astrocytes in Obesity

Endocrinology and Metabolism Clinics of North America, 2013
Obesity is characterized by a chronic and low-grade inflammation in tissues including the hypothalamus. Hypothalamic inflammation is considered an early and determining factor for the onset of obesity, a factor that occurs even before body weight gain. Within the hypothalamus, microglia and astrocytes produce cytokines that drive inflammatory responses.

Measurements of Astrocyte Proliferation

2011
Astrocytes, the most abundant cell type in the brain, proliferate during brain development. While it is generally accepted that mature astrocytes do not proliferate, neural stem cells, which have characteristics of astrocytes, retain the ability of self-renewal.

Primary astrocyte cultures?a key to astrocyte function

Cellular and Molecular Neurobiology, 1983
Morphological studies have established the ubiquitous nature of astrocytes in the CNS. Their processes surround capillaries and synapses, form the subpial and subependymal layers, and seemingly invest every neuronal surface not covered by other neuronal surfaces or oligodendroglial membranes.

Role of PACAP in Astrocytes and Astrocytic Tumors

2016
In the central nervous system (CNS), astrocytes are the most numerous among glial cells and have diverse physiological functions. These cells also play an important role in many CNS disorders and pathologies. Pituitary adenylate cyclase activating polypeptide (PACAP) is abundantly expressed in the CNS, acting as a neuroprotectant against various ...
