Advanced Materials Technologies, EarlyView.ABSTRACT Quantifying oral polymorphonuclear neutrophils (oPMNs) is a clinically validated approach for assessing periodontal inflammation. However, current methods, such as manual hemocytometry and flow cytometry, are time‐consuming (>3 h), require invasive sampling, and depend on staining and complex instrumentation, making them unsuitable for point ...

3D Printed Omniphobic Slippery Liquid Infused Porous Surfaces for Low Surface Tension Repellency
Advanced Materials Technologies, EarlyView.A 3D printing strategy fabricates omniphobic slippery liquid‐infused porous structures with lubricant reservoirs and interconnected microchannels. A post‐printing surface treatment modifies the porous surface to ensure compatibility with the infused fluorinated lubricant.

The Membrane Attack Complex of Complement
Annual Review of Immunology, 1986Cell-killing mechanisms are essential components of host defense against infectious agents, parasites, and malignant cells. We distinguish humoral and cellular killing mechanisms. Complement utilizes specific proteins to assemble its killer molecule. Macrophages generate active oxygen radicals that injure target membranes. Lymphocytes, like complement,

Microvascular Deposition of Complement Membrane Attack Complex in Dermatomyositis
New England Journal of Medicine, 1986We examined the role of the complement system in the pathogenesis of dermatomyositis. Using an antibody against the neoantigens of the terminal C5b-9 membrane attack complex, we performed immunocytochemical studies that localized this complex to the intramuscular microvasculature (arterioles and capillaries) of muscle biopsy specimens from 10 of 12 ...

Springer Seminars in Immunopathology, 1984
The “killer molecule” of complement is the membrane attack complex (MAC). It constitutes a supramolecular organization that is composed of approximately 20 protein molecules and has a molecular weight of about 1.7 million. The complex has five precursors, C5, C6, C7, C8, and C9, which are hydrophilic glycoproteins with molecular weights ranging from 70

The membrane attack complex ofXeopus laevis complement
Experientia, 1987Rabbit erythrocyte membranes lyzed by Xenopus laevis serum exhibited a typical ultrastructural complement lesion with an inner diameter of 80 +/- 9 A. The protein pattern associated with lyzed membrane is compared to a similar human preparation.

Membrane permeability to macromolecules mediated by the membrane attack complex
Biochemistry, 1989A simple and well-defined system of purified phospholipids and human complement proteins was used to study membrane permeability to macromolecules mediated by the membrane attack complex (MAC) of complement. Large unilamellar vesicles (LUVs) of phosphatidylcholine (PC) or phosphatidylserine (PS) containing trapped macromolecules [bovine pancreatic ...

Membrane signaling by complement C5b-9, the membrane attack complex
Immunologic Research, 1993The terminal complement complexes C5b-7, C5b-8 and C5b-9 are able to generate nonlethal cell signals. One universal consequence of a cell being targeted by C5b-8 or C5b-9 is an influx of Ca2+. In addition, other second messengers, including cAMP, inositol phosphate intermediates and arachidonate metabolites, are generated by the terminal complement ...

Complement Membrane Attack Complexes in Pathologic Disc Tissues
Spine, 2003Complement membrane attack complexes were located in lumbar spine disc tissues by immunohistochemistry. Their occurrence was compared in control discs obtained from organ donors (CD), discs showing a normal macroscopic anatomy, samples of intervertebral disc herniations (DH), and intervertebral discs found to be degenerated by discography, but not ...
