My2-Acetone-diacetone[my3-tris­(trifluoro­meth­yl)methano­lato]bis­[my2-tris­(trifluoro­meth­yl)methano­lato]trilithium [PDF]

, 2010
The title compound, [Li3(C4F9O)3(C3H6O)3], features an open Li/O cube with an Li ion missing at one corner. Three of the four bridging O atoms of the cube carry a fluorinated tert-butyl residue, whereas the fourth is part of an acetone mol­ecule.

A C3(H20) recycling pathway is a component of the intracellular complement system [PDF]

, 2017
An intracellular complement system (ICS) has recently been described in immune and nonimmune human cells. This system can be activated in a convertase-independent manner from intracellular stores of the complement component C3. The source of these stores

Incorporation of Novel Synthetic Glycolipids in Liposomal Nanoparticles Affects Opsonization and In Vivo Clearance

Angewandte Chemie, EarlyView.
We prepared five glycosylated liposomal nanoparticles (G‐LNPs) to investigate the role of glycosylation and protein corona in modulating the in vivo behavior of G‐LNPs. We show that IgG and complement C3 adsorption enhanced liposomal nanoparticle clearance, with IgG promoting subsequent C3 binding.

Zinc-induced self-association of complement C3b and Factor H: implications for inflammation and age-related macular degeneration. [PDF]

, 2013
The sub-retinal pigment epithelial deposits (sRPEds) that are a hallmark of age-related macular degeneration (AMD) contain both C3b and mM levels of zinc.

Toxoplasma gondii Recruits Factor H and C4b-Binding Protein to Mediate Resistance to Serum Killing and Promote Parasite Persistence in vivo

Frontiers in Immunology, 2020
Regulating complement is an important step in the establishment of infection by microbial pathogens. Toxoplasma gondii actively resists complement-mediated killing in non-immune human serum (NHS) by inactivating C3b, however the precise molecular basis ...

Role of Electrostatic Hotspots in the Selectivity of Complement Control Proteins Toward Human and Bovine Complement Inhibition

Frontiers in Molecular Biosciences, 2021
Poxviruses are dangerous pathogens, which can cause fatal infection in unvaccinated individuals. The causative agent of smallpox in humans, variola virus, is closely related to the bovine vaccinia virus, yet the molecular basis of their selectivity is ...
