Optimized survival of hippocampal neurons in B27‐supplemented neurobasal™, a new serum‐free medium combination Tập 35 Số 5 - Trang 567-576 - 1993
Gregory J. Brewer, John R. Torricelli, E K Evege, Paul J. Price
AbstractWe have systematically optimized the concentrations of 20 components of
a previously published serumfree medium (Brewer and Cotman, Brain Res 494:
65‐74, 1989) for survival of rat embryonic hippocampal neurons after 4 days in
culture. This serum‐freemedium Supplement, B27, produced neuron survival above
60% independent of plating density above 160 plated cells/mm2 For isolated cells

Curcumin có hiệu quả ức chế tạo ra fibril β-amyloid liên quan đến Alzheimer trong thí nghiệm in vitro Dịch bởi AI Tập 75 Số 6 - Trang 742-750 - 2004
Kenjiro Ono, Kazuhiro Hasegawa, Hironobu Naiki, Masahito Yamada
Trừu tượngViệc ức chế tích tụ peptide amyloid β (Aβ) và sự hình thành các sợi
fibril β-amyloid (fAβ) từ Aβ, cũng như sự bất ổn của những fAβ đã hình thành
trước đó trong hệ thần kinh trung ương, sẽ là những đích điều trị hấp dẫn để
điều trị bệnh Alzheimer (AD). Chúng tôi đã báo cáo trước đây rằng axit
nordihydroguaiaretic (NDGA) và các polyphenol liên quan đến rượu vang ức chế sự
hình thành fAβ từ... hiện toàn bộ

T‐lymphocyte entry into the central nervous system Tập 28 Số 2 - Trang 254-260 - 1991
William F. Hickey, Benjamin Hsu, Hironobu Kimura
AbstractThe entry of T‐lymphocytes into the parenchyma of the central nervous
system is a critical early feature in the pathogenesis of many experimental and
spontaneously occurring immune‐mediated illnesses. The physiological mechanisms
controlling this entry have not been elucidated. This study reports that T‐cell
entry into the rat CNS appears to be primarily dependent upon the activation

Microglia in health and disease Tập 81 Số 3 - Trang 302-313 - 2005
Seung Up Kim, Jean de Vellis
AbstractMicroglia, one of three glial cell types in the central nervous system
(CNS), play an important role as resident immunocompetent and phagocytic cells
in the CNS in the event of injury and disease. It was del Rio Hortega in 1927
who determined that microglia belong a distinct glial cell type apart from
astrocytes and oligodendrocytes, and since 1970s there has been wide recognition
that mic... hiện toàn bộ
Intravenous bone marrow stromal cell therapy reduces apoptosis and promotes endogenous cell proliferation after stroke in female rat Tập 73 Số 6 - Trang 778-786 - 2003
Jieli Chen, Yi Li, Mark Katakowski, Xiaoguang Chen, Lei Wang, Dunyue Lu, Mei Lü, Subhash C. Gautam, Michael Chopp
AbstractThe present study investigates the induction of neurogenesis, reduction
of apoptosis, and promotion of basic fibroblast growth factor (bFGF) expression
as possible mechanisms by which treatment of stroke with bone marrow stromal
cells (MSCs) improves neurological functional recovery. Additionally, for the
first time, we treated cerebral ischemia in female rats with intraveneous
administrat... hiện toàn bộ
Receptor‐mediated transcytosis of transferrin across the blood‐brain barrier Tập 18 Số 2 - Trang 299-304 - 1987
Jordan B. Fishman, Joshua B. Rubin, J. V. Handrahan, James R. Connor, Richard E. Fine
AbstractThe perfusion of rat brain with 125I‐transferrin resulted in a
receptor‐mediated uptake of transferrin into the endothelium of the blood‐brain
barrier followed by its detecation in the brain. During a pulsechase experiment,
125I‐transferrin accumulated in the endothelial cells during the pulse, with a
decrease of this intraendothelial radioactivity during the chase associated a
concomitant... hiện toàn bộ
Gene expression profiling of 12633 genes in Alzheimer hippocampal CA1: Transcription and neurotrophic factor down‐regulation and up‐regulation of apoptotic and pro‐inflammatory signaling Tập 70 Số 3 - Trang 462-473 - 2002
Vittorio Colangelo, Jill R. Schurr, Melvyn J. Ball, Ricardo Palacios Peláez, Nicolás G. Bazán, Walter J. Lukiw
AbstractAlterations in transcription, RNA editing, translation, protein
processing, and clearance are a consistent feature of Alzheimer's disease (AD)
brain. To extend our initial study (Alzheimer Reports [2000] 3:161‐167), RNA
samples isolated from control and AD hippocampal cornu ammonis 1 (CA1) were
analyzed for 12633 gene and expressed sequence tag (EST) expression levels using
DNA microarrays... hiện toàn bộ
The interaction of circRNAs and RNA binding proteins: An important part of circRNA maintenance and function Tập 98 Số 1 - Trang 87-97 - 2020
Jiankun Zang, Dan Lu, Chunxue Wang
AbstractThe widespread expression of circular RNAs (circRNAs) is regarded as a
feature of gene expression in highly diverged eukaryotes. Recent studies have
shown that circRNAs can act as a miRNA sponge to repress miRNA function,
participate in splicing of target genes, translate genes into protein and
interact with RNA binding proteins (RBPs). RBPs are a broad class of proteins
involved in gene t... hiện toàn bộ
Peroxide detoxification by brain cells Tập 79 Số 1-2 - Trang 157-165 - 2005
Ralf Dringen, Petra G. Pawlowski, Johannes Hirrlinger
AbstractPeroxides are generated continuously in cells that consume oxygen. Among
the different peroxides, hydrogen peroxide is the molecule that is formed in
highest quantities. In addition, organic hydroperoxides are synthesized as
products of cellular metabolism. Generation and disposal of peroxides is a very
important process in the human brain, because cells of this organ consume 20% of
the ox... hiện toàn bộ
