Binding of Mycobacterium tuberculosis to complement receptor type 3 expressed in mammalian cells : dependence on serum opsonins
… receptor and the complement receptor type 3 (CR3) may support nonopsonic binding. CR3, a β₂ integrin, is a target for diverse intracellular pathogens, but its role in nonopsonic binding remains uncertain. We have examined the binding of M. tb. to human CR3 heterologously expressed in Chinese …

Integrin Modulating Factor 1 (IMF-1): A lipid that modulates leukocyte integrins
… family termed complement receptor type 3 (CR3, also known as α<sub>M</sub>β<sub>2</sub>, Mac-1, Mo1, or CD11b/CD18) that functions in several cell-cell and cell-substratum adhesion events. The capacity of CR3 to mediate adhesion may be rapidly and reversibly enhanced without changes in the …

Molecular Mechanisms Involved in Interleukin-1β Release by Macrophages Exposed to Metal Ions from Implantable Biomaterials
… studies have shown that, in macrophages, Co2+, Cr3+, and Ni2+ can activate the NLR family pyrin domain-containing protein 3 (NLPR3) inflammasome, which is responsible for interleukin(IL)-1β production through caspase-1. Furthermore, these ions are known to induce oxidative stress, and …

The Domains of The Catalytic Subunit of The Eukaryotic Rna Degrading Exosome, Rrp44P, Have Distinct Functions
… an uncharacterized N-terminus, which includes a CR3 region and PIN domain. In an effort to characterize the cellular functions of the domains of Rrp44p, this study identified a second nuclease active site in the PIN domain. Specifically, the PIN domain exhibits endoribonuclease activity in vitro …

Környezetszennyező anionos radionuklidok megkötése módosított agyagkőzeten vizes és művizeletes közegből
Korábban már bizonyították, hogy a Cr3+- és Sn2+-ionokkal módosított bentonitok, vizes közegből közel 100 %-ban megkötik a 99mTc izotópot. Ebben a munkában azt vizsgáltam, hogy egy több ionból álló oldat milyen befolyással van erre a megkötődésre. Erre a célra alkalmas a művizelet. Ezért a …

A consecutive reaction model and kinetics of cr2o3 reduction from slag by carbon dissolved in molten iron
… (cr2+)is the intermediary product. The rate of (cr3+) reduction remained the same in an argon or carbon monoxide atmosphere whilst an argon atmosphere increased the rate of (cr2+) reduction by a factor of about 1.4,compared to a carbon monoxide atmosphere. The rate of reduction of the chronium …
