Small heat shock proteins induce a cerebral inflammatory reaction.
More than 80% of Alzheimer's disease (AD) patients have some degree of cerebral amyloid angiopathy (CAA). In addition to arteries and veins, capillaries can also be affected. Capillary CAA (capCAA), rather than CAA in larger vessels, is associated with flame-like amyloid-beta (Aβ) deposits that may extend beyond the vessel wall and radiate into the neuropil, a phenomenon also known as "dyshoric...
متن کاملDevelopmental expression of Drosophila melanogaster small heat-shock proteins.
We have investigated the developmental expression of the small heat-shock proteins (hsps) during embryogenesis and in adult flies by immunocytology using an antibody that specifically identifies the small hsps. Antibody staining of unstressed early embryos reveals a predominantly cytoplasmic, homogeneous distribution of the small hsps throughout the embryo. At 6h of development small hsp expres...
متن کاملHeat shock proteins induce pores in membranes.
Human heat shock protein (hsp) 70 and bacterial protein groEL promote leakage of calcein from liposomes induced by human serum albumin signal peptide, by S. aureus alpha toxin or by diphtheria toxin. Hsp 70 and groEL, as well as two mycobacterial homologues hsp 71 and hsp 65, induce ion conducting pores across planar lipid bilayers at low or neutral pH. It is concluded that hsp induce pores in ...
متن کاملThe Relationship between the Expression of Small Heat-Shock Proteins and Suppression of OCT4B1
Background: OCT4B1, a variant of OCT4, is expressed in both cancer cells and tissues. This variant has a main role in the regulation of both apoptotic and stress (heat-shock proteins) pathways. The aim of this study was to investigate the effects of OCT4B1 silencing on the expression of small heat-shock proteins (sHSPs)in three human tumor cell lines. Methods:...
متن کاملSmall heat-shock proteins: paramedics of the cell.
The small heat-shock proteins (sHSPs) comprise a family of molecular chaperones which are widespread but poorly understood. Despite considerable effort, comparatively few high-resolution structures have been determined for the sHSPs, a likely consequence of their tendency to populate ensembles of inter-converting conformational and oligomeric states at equilibrium. This dynamic structure appear...
