Neutrophil extracellular traps (NETs) represent an extracellular, spider's web-like structure resulting from cell death of neutrophils. NETs play an important role in innate immunity against microbial infection, but their roles in human pathological processes remain largely unknown. NETs and fibrin meshwork both showing fibrillar structures are observed at the site of fibrinopurulent inflammati...

Cyanobacteria are unicellular photosynthetic prokaryotes. The enzymes of the Calvin cycle of photosynthesis are known to be randomly distributed in the cytosol of these organisms. Such random location of these soluble enzymes, is in disparity with their precise function and regulation for photosynthetic carbon assimilation. This location has been conjectured from the fact that they can be isola...

A gold ridge microstructure fabricated to a height of lambda/8 on a high-reflectivity substrate behaves as a wave-front-splitting self-referencing interferometer in phase quadrature when illuminated by a Gaussian laser beam and observed in the far field along the optic axis. When immuno-gammaglobulin (IgG) antibodies are selectively immobilized on the gold microstructure, they recognize and bin...

The fine structurel distribution of troponin on thin filaments in developing myofibrils was investigated by the use of immunoelectron microscopy. Embryonic chick skeletal muscle cells grown in vitro were treated with antibodies against each of the troponin components (troponin T, I, and C) from adult chicken muscles. Each antibody was distributed along the thin filaments with a period of 38 nm....

Many plasma membrane components are organized into detergent-resistant membrane microdomains referred to as lipid rafts. However, there is much less information about the organization of membrane components into microdomains outside of lipid rafts. Furthermore, there are few approaches to determine whether different membrane components are colocalized in microdomains as small as lipid rafts. We...

The interpodocyte slit diaphragm is an essential structure for maintaining the functional glomerular filtration barrier. The slit diaphragm is proposed to consist of an interacting meshwork of nephrin molecules. Earlier studies with tagged proteins have suggested that the intracellular part of nephrin interacts with CD2-associated protein (CD2AP). This study was addressed to show by coimmunopre...
