Presence of intracytoplasmatic apolipoprotein D (apo D), a lipophilic ligand transporter, was investigated in normal human brains between 20 and 55 years, using an anti-human apolipoprotein D antibody and extravidin-biotin-enhanced immunohistochemistry. Apo D immunoreactivity was found in neuroglial cells of white matter in all sampled brain regions studied(More)
OBJECTIVE To describe a simple method to achieve the differential selection and subsequent quantification of the strength signal using only one section. STUDY DESIGN Several methods for performing quantitative histochemistry, immunocytochemistry or hybridocytochemistry, without use of specific commercial image analysis systems, rely on pixel-counting(More)
The lipocalin apolipoprotein D (Apo D) is upregulated in peripheral nerves following injury and in regions of the central nervous system, such as the cerebral cortex, hippocampus, and cerebellum, during aging and progression of certain neurological diseases. In contrast, few studies have examined Apo D expression in the brainstem, a region necessary for(More)
Apolipoprotein D (Apo D) is a lipocalin expressed in a wide variety of mammalian tissues. Different studies have shown that this protein is upregulated in the central nervous system (CNS) in several neuropathological conditions, after traumatic brain injury and in aging. The Apo D promoter shows 3 estrogen response elements and it has been shown that its(More)
Astrocytosis is a hallmark of damage that frequently occurs during aging in human brain. Astrocytes proliferate in elderly subjects, becoming hypertrophic and highly immunoreactive for glial fibrillary acidic protein (GFAP). These cells are one type that actively responds in the repair and reorganization of damage to the neural parenchyma and are a source(More)
Apolipoprotein D (Apo D) is a lipid binding protein whose expression is strongly induced in the mammalian brain during aging and age-dependent neurodegenerative diseases such as Alzheimer's disease (AD), where it can play an important function as a neuroprotective and antioxidant protein. Increasing evidence suggests that the gradual increase in free(More)
Vincristine is an antitumor drug that inhibits microtubule polymerization, causes G2/M arrest and induces apoptosis. 2D-PAGE and MALDI-TOF-MS analysis of vincristine effects on MCF7 cells, revealed a vincristine upregulated form and a vincristine downregulated form of the antiapoptotic protein HSP27. These findings linked to the lack of vincristine effect(More)
Apolipoprotein D (ApoD) is a secreted glycoprotein that is markedly induced in several pathological and stressful conditions in the nervous system. In the central nervous system, ApoD expression is upregulated during aging, after traumatic brain injury, and in several human neuropathologies such as Alzheimer's disease (AD), where it is found associated with(More)
Apolipoprotein D (Apo D) is a secreted glycoprotein, member of the lipocalin superfamily, with a related beneficial role in metabolism and lipid transport due to the presence of a binding pocket that allows its interaction with several lipids. Nowadays, it has been clearly demonstrated that Apo D expression is induced and its subcellular location undergoes(More)
The aim of cell therapy is to replace, repair, or enhance the function of damaged tissues or organs. Several factors complicate the development of cellular therapies. Of primary importance is protection of the implanted cells from the host's immune system. Cells are encapsulated in selectively semipermeable and biocompatible membranes that block entry of(More)
